Why Do People Get Their Tonsils Removed? Common Reasons Explained

Tonsillectomy, the surgical removal of tonsils, remains one of the most frequently performed procedures in otolaryngology, with over 500,000 operations conducted annually in the United States. These lymphoid tissues, positioned at the back of the throat, serve as frontline defenders against pathogens entering through the mouth, yet they sometimes become more problematic than protective. When tonsils cause recurrent infections, breathing difficulties, or sleep-related disorders, surgical intervention often becomes the most effective treatment option.

“Why do people get their tonsils removed?” – This comprehensive guide explores the primary medical indications for tonsillectomy, detailed procedural information, recovery expectations, and long-term outcomes. We’ll examine when conservative treatments fail, how ENT specialists determine surgical candidacy, and what patients can expect throughout their journey from consultation to complete recovery. Understanding these factors helps patients and families make informed decisions about this significant medical procedure.

Understanding Tonsils and Tonsillectomy

What Are Tonsils?

Tonsils are paired masses of lymphoid tissue strategically located on either side of the posterior throat. These palatine tonsils function as immunological sentinels, containing specialized cells that attack and destroy bacteria, viruses, and other microorganisms attempting to enter the body through the oral cavity. As part of Waldeyer’s ring, they work alongside adenoids and lingual tonsils to form the body’s first line of immune defense.

The tonsils’ strategic positioning allows them to sample antigens from inhaled air and ingested materials, initiating immune responses when necessary. However, their location and structure, featuring deep crypts and crevices, can sometimes trap debris and bacteria, leading to chronic inflammation or infection.

Defining Tonsillectomy

Tonsillectomy (pronounced tahn-suh-LEK-tuh-mee) refers to the complete surgical excision of both palatine tonsils. This procedure primarily addresses sleep-disordered breathing, chronic tonsillitis, and recurrent throat infections that haven’t responded to conservative medical management. Modern surgical techniques have evolved significantly, offering various approaches from traditional cold steel dissection to advanced radiofrequency ablation methods.

The operation may be performed in conjunction with adenoidectomy (removal of adenoids), particularly in pediatric patients experiencing upper airway obstruction. This combined approach, called adenotonsillectomy, addresses both tonsillar and adenoidal contributions to breathing difficulties and sleep apnea.

Prevalence and Demographics

While tonsillectomy rates have declined from their peak in the mid-20th century, the procedure remains widely performed across all age groups. Current statistics indicate that pediatric patients comprise the majority of cases, though adult tonsillectomies have increased due to better recognition of sleep-disordered breathing in adults.

The shift in surgical indications has evolved from primarily treating recurrent infections to addressing obstructive sleep apnea and quality-of-life issues. This change reflects improved understanding of sleep medicine and the long-term consequences of untreated sleep disorders.

Primary Medical Indications for Tonsillectomy

Recurrent, Chronic, or Severe Tonsillitis

Recurrent tonsillitis represents the most traditional indication for surgical intervention. This condition involves repeated episodes of tonsillar inflammation, infection, or irritation that significantly impact a patient’s quality of life and overall health status.

Clinical Criteria for Surgical Consideration

The Paradise Criteria, established through landmark research, provide standardized guidelines for determining when tonsillectomy is medically justified for recurrent infections:

Time Period	Minimum Episode Frequency	Additional Requirements
Past 12 months	7 or more episodes	Well-documented cases
Past 24 months	5 episodes per year	Consistent pattern
Past 36 months	3 episodes per year	Failed medical management

Each qualifying episode must feature specific clinical characteristics: fever exceeding 38.3°C (101°F), cervical lymphadenopathy, tonsillar exudate, or positive bacterial culture results. Healthcare providers must document failed attempts at conservative treatment, including appropriate antibiotic therapy for bacterial infections.

Complications and Refractory Cases

Peritonsillar abscess (quinsy) represents a serious complication where pus accumulates behind the tonsil, creating a medical emergency requiring immediate intervention. While initial treatment involves antibiotic therapy and drainage, recurrence rates of 10-15% often necessitate prophylactic tonsillectomy to prevent future episodes.

Bacterial infections that persistently resist antibiotic treatment may indicate the presence of biofilms or protected bacterial communities within tonsillar crypts. These treatment-resistant cases often benefit from surgical removal when medical management repeatedly fails.

Obstructive Sleep Apnea and Breathing Difficulties

Tonsillar hypertrophy can significantly obstruct the upper airway, leading to various breathing-related sleep disorders. This indication has become increasingly prominent as sleep medicine has advanced and recognition of pediatric sleep apnea has improved.

Obstructive Sleep Apnea Syndrome

Obstructive sleep apnea (OSA) occurs when enlarged tonsils partially or completely block the airway during sleep, causing repeated breathing interruptions. Patients experience fragmented sleep, oxygen desaturation, and cardiovascular stress throughout the night. Children with OSA may exhibit behavioral problems, poor academic performance, and growth retardation due to disrupted sleep architecture.

The Apnea-Hypopnea Index (AHI) measures severity:

• Mild OSA: 5-15 events per hour
• Moderate OSA: 15-30 events per hour
• Severe OSA: >30 events per hour

Associated Symptoms and Complications

Chronic mouth breathing develops as patients compensate for nasal and oropharyngeal obstruction. This can lead to dental problems, facial growth abnormalities, and increased susceptibility to upper respiratory infections.

Loud snoring, while common, doesn’t always indicate sleep apnea. However, when combined with witnessed apnea episodes, restless sleep, and daytime fatigue, it suggests significant sleep-disordered breathing requiring evaluation.

Advanced Diagnostic Considerations

ENT specialists employ various assessment tools beyond clinical examination to determine surgical candidacy. The Brodsky grading system evaluates tonsillar size on a scale of 0-4, with grades 3-4 indicating significant airway compromise.

Polysomnography (sleep studies) provides objective data about breathing patterns, oxygen levels, and sleep quality. This comprehensive evaluation helps differentiate between simple snoring and clinically significant sleep apnea, guiding treatment decisions.

Imaging studies, including lateral neck X-rays or CT scans, may be necessary in complex cases to evaluate the entire upper airway and identify additional sources of obstruction beyond the tonsils.

Additional Indications for Surgery

Tonsillar Hemorrhage

Spontaneous bleeding from tonsils, while uncommon, can indicate underlying pathology requiring surgical intervention. Recurrent hemorrhage episodes may suggest vascular malformations or chronic inflammation that won’t resolve with conservative treatment.

Rare Tonsillar Disorders

Malignancy, though uncommon, can affect one or both tonsils. Asymmetric tonsillar enlargement, particularly when accompanied by hard consistency, ulceration, or persistent pain, requires immediate evaluation to exclude neoplastic processes.

Unilateral tonsillar hypertrophy warrants careful assessment, as significant asymmetry may indicate underlying pathology. ENT specialists typically recommend surgical removal for diagnostic purposes when one tonsil is markedly larger than its counterpart, especially if associated with dysphagia, persistent pain, or cervical lymphadenopathy.

Halitosis and Tonsil Stones

Chronic halitosis related to tonsilloliths (tonsil stones) represents a quality-of-life indication for surgery. These calcified deposits form within tonsillar crypts, containing bacteria, food particles, and cellular debris that produce sulfur compounds responsible for persistent bad breath.

Conservative management includes:

• Regular gargling with salt water
• Manual removal techniques
• Oral irrigators for crypt cleaning
• Antibacterial mouthwashes

When conservative measures fail and halitosis significantly impacts social functioning, tonsillectomy may be considered despite the absence of infection or airway obstruction.

The Tonsillectomy Procedure

Preoperative Preparation and Assessment

Comprehensive preoperative evaluation ensures patient safety and optimal surgical outcomes. This process involves multiple components designed to identify potential risks and prepare patients for the procedure.

Medical History and Physical Examination

Healthcare providers conduct thorough reviews of medical history, focusing on bleeding disorders, previous anesthetic complications, and current medications. Family history of anesthetic problems or coagulopathies requires special attention, as these conditions can significantly impact surgical safety.

Physical examination includes assessment of:

• Tonsillar size and appearance
• Cervical lymph nodes
• Oral cavity anatomy
• Airway assessment for intubation difficulty

Laboratory Studies and Diagnostic Testing

Routine preoperative testing may include:

• Complete blood count (CBC)
• Coagulation studies (PT/PTT) if bleeding history suggests
• Type and screen for potential blood transfusion

Sleep studies may be recommended for patients with suspected sleep apnea to document severity and guide postoperative care planning.

Preoperative Instructions and Guidelines

Timeframe	Instructions
2 weeks prior	Discontinue aspirin, NSAIDs, and herbal supplements
1 week prior	Review medications with anesthesia team
Night before	Nothing by mouth after midnight
Day of surgery	Take only approved medications with small sips of water

Psychological Preparation and Support

Pediatric patients benefit from age-appropriate explanations and preparation programs. Child life specialists may provide comfort items, distraction techniques, and coping strategies to reduce anxiety. Parents receive guidance on supporting their children through the perioperative period.

Intraoperative Techniques and Procedures

Modern tonsillectomy employs various surgical approaches, each with specific advantages and indications. The choice of technique depends on patient factors, surgeon preference, and institutional protocols.

Anesthetic Management

General anesthesia with endotracheal intubation provides optimal surgical conditions and airway protection. Anesthesiologists may use specialized techniques like total intravenous anesthesia (TIVA) to reduce postoperative nausea and vomiting.

Local anesthesia with conscious sedation may be appropriate for selected adult patients, though general anesthesia remains the standard approach for most cases.

Surgical Approaches and Techniques

Cold Steel Dissection Traditional scalpel dissection remains the gold standard for complete tonsillectomy. This technique provides excellent visualization, precise tissue handling, and familiar anatomy for surgeons. Hemostasis is achieved through electrocautery or suture ligation.

Electrocautery Methods Monopolar and bipolar electrocautery techniques use electrical energy to simultaneously cut tissue and achieve hemostasis. These methods may reduce operative time but can cause more thermal injury to surrounding tissues.

Harmonic Scalpel Technology Ultrasonic cutting devices use high-frequency vibrations to cut and coagulate tissue simultaneously. This technology may reduce thermal spread compared to traditional electrocautery while maintaining efficient hemostasis.

Radiofrequency Ablation Controlled thermal injury using radiofrequency energy can reduce tonsillar tissue volume while preserving some immune function. This technique is sometimes used for partial tonsillectomy in selected cases.

Laser-Assisted Techniques Carbon dioxide lasers provide precise tissue removal with excellent hemostasis. However, specialized equipment requirements and potential airway fire risks limit widespread adoption.

Postoperative Immediate Care

Recovery Room Management

Patients transfer to post-anesthesia care units (PACU) for monitoring of vital signs, airway patency, and surgical site assessment. Nursing staff watch for signs of bleeding, respiratory compromise, and adequate pain control.

Common immediate postoperative findings include:

• Mild to moderate throat pain
• Low-grade fever (typically <101°F)
• Voice changes or muffled speech
• Halitosis from healing tissues

Discharge Criteria and Planning

Most tonsillectomies are performed as outpatient procedures, with same-day discharge when patients meet specific criteria:

• Stable vital signs
• Adequate oral intake
• Appropriate pain control
• No signs of bleeding
• Responsible adult caregiver available

Certain patient populations may require overnight observation:

• Children under 3 years of age
• Patients with severe sleep apnea
• Those with significant comorbidities
• Cases with intraoperative complications

Recovery Timeline and Expectations

Comprehensive Recovery Phases

Recovery from tonsillectomy follows predictable phases, though individual experiences vary based on age, surgical technique, and patient factors. Understanding these phases helps patients and families prepare for the healing process.

Days 1-3: Immediate Postoperative Period

The initial recovery phase typically involves the most significant discomfort and requires careful monitoring. Patients experience:

Primary Symptoms:

• Severe throat pain, often described as “razor-like”
• Difficulty swallowing liquids and soft foods
• Low-grade fever (99-101°F)
• Ear pain due to referred pain from shared nerve pathways
• Voice changes and muffled speech
• Fatigue and general malaise

Critical Monitoring Points:

• Hydration status and oral intake adequacy
• Pain management effectiveness
• Signs of bleeding or infection
• Fever patterns and response to medication

Days 4-7: Peak Discomfort Phase

Paradoxically, pain often intensifies during this period as initial inflammation peaks and nerve endings become more sensitive. This phase requires vigilant symptom management and family support.

Characteristic Features:

• Maximum pain intensity, particularly with swallowing
• Persistent low-grade fever
• Continued halitosis from healing tissues
• Gradual improvement in voice quality
• Beginning of eschar (scab) formation

Days 8-14: Healing and Resolution

The second week typically brings significant improvement as tissues heal and normal function returns. Patients notice gradual return to normal activities and diet.

Progressive Improvements:

• Decreasing pain levels
• Improved appetite and oral intake
• Resolution of fever
• Return of normal voice
• Increased energy levels

Pain Management Strategies

Effective analgesia remains crucial for successful recovery, enabling adequate hydration and nutrition while minimizing complications.

Pharmacological Approaches

Primary Analgesics:

• Acetaminophen: First-line therapy for mild to moderate pain
• Ibuprofen: Anti-inflammatory properties help reduce swelling
• Prescription opioids: Reserved for severe pain, used judiciously

Medication Scheduling:

• Around-the-clock dosing more effective than as-needed approach
• Premedication before meals to facilitate eating
• Nighttime doses to ensure sleep quality

Non-Pharmacological Interventions

Comfort Measures:

• Cold compresses applied to neck externally
• Humidified air to prevent throat drying
• Quiet environment to promote rest
• Elevation of head during sleep

Dietary Modifications:

• Cold foods and beverages for soothing effect
• Smooth textures to minimize irritation
• Adequate fluid intake to prevent dehydration
• Avoidance of acidic, spicy, or rough foods

Nutritional Guidelines and Dietary Progression

Proper nutrition supports healing while preventing complications. Dietary advancement follows a systematic approach based on patient tolerance.

Immediate Postoperative Diet (Days 1-3)

Food Category	Recommended Options	Foods to Avoid
Liquids	Water, ice chips, clear broths	Citrus juices, hot beverages
Soft Foods	Ice cream, pudding, applesauce	Yogurt with fruit pieces
Frozen Items	Popsicles, frozen yogurt	Hard ice cubes

Transitional Diet (Days 4-10)

Gradual introduction of more varied textures while maintaining emphasis on soft, non-irritating foods:

• Scrambled eggs and soft pasta
• Mashed potatoes and smooth soups
• Soft breads without crusts
• Well-cooked vegetables

Return to Regular Diet (Days 10-14)

Most patients can resume normal eating habits by the second week, though some may require additional time for complete comfort with all food textures.

Potential Complications and Risk Management

Anesthetic-Related Complications

Modern anesthetic techniques have significantly reduced perioperative risks, though complications can still occur across the spectrum of severity.

Common Anesthetic Issues

• Postoperative nausea and vomiting (PONV)
• Sore throat from intubation
• Temporary voice hoarseness
• Muscle aches and headaches

Serious Anesthetic Complications

• Malignant hyperthermia (extremely rare)
• Anaphylactic reactions to medications
• Cardiac or respiratory complications
• Aspiration pneumonia

Surgical Complications and Management

Postoperative Hemorrhage

Bleeding represents the most serious potential complication, occurring in 2-5% of cases. Two distinct patterns exist:

Primary Hemorrhage (0-24 hours):

• Usually due to inadequate intraoperative hemostasis
• Requires immediate return to operating room
• May necessitate blood transfusion in severe cases

Secondary Hemorrhage (Days 5-10):

• More common, often coinciding with eschar separation
• May be managed conservatively if minimal
• Severe bleeding requires emergency intervention

Warning Signs Requiring Immediate Medical Attention:

• Bright red blood from mouth or nose
• Frequent swallowing or spitting of blood
• Vomiting blood or coffee-ground material
• Signs of hemodynamic instability

Infection and Inflammatory Complications

While rare due to the oral cavity’s natural bacterial environment, significant infections can occur:

Local Infections:

• Persistent or worsening throat pain beyond day 5
• High fever (>102°F) unresponsive to medication
• Purulent drainage or foul odor

Systemic Complications:

• Pneumonia from aspiration
• Bacteremia in immunocompromised patients
• Deep neck space infections (very rare)

Respiratory Difficulties

Upper Airway Swelling:

• Tongue and soft palate edema
• Most common in first 24 hours
• May require steroids or extended observation

Persistent Sleep Apnea:

• Temporary worsening due to surgical swelling
• Usually resolves as healing progresses
• May require CPAP therapy during recovery

Dehydration and Nutritional Concerns

Inadequate fluid and caloric intake can lead to secondary complications requiring intervention.

Dehydration Warning Signs

Pediatric Patients:

• Decreased urination (<2-3 times daily)
• Crying without tears
• Dry mouth and mucous membranes
• Lethargy or irritability

Adult Patients:

• Decreased urine output
• Dizziness or lightheadedness
• Dry mouth and skin
• Concentrated urine

Management Strategies

Mild dehydration often responds to increased oral intake with electrolyte solutions. Severe cases may require:

• Emergency department evaluation
• Intravenous fluid resuscitation
• Possible hospitalization for monitoring

Long-Term Outcomes and Benefits

Infection Reduction and Quality of Life

Tonsillectomy provides significant long-term benefits for appropriately selected patients, with improvements often persisting for years following surgery.

Reduced Infection Frequency

Studies demonstrate substantial decreases in:

• Streptococcal pharyngitis episodes
• Antibiotic usage for throat infections
• School or work days missed due to illness
• Healthcare visits for throat-related problems

The magnitude of benefit correlates with preoperative infection frequency, with patients meeting Paradise Criteria experiencing the most dramatic improvements.

Quality of Life Enhancements

Physical Improvements:

• Decreased throat pain and discomfort
• Improved ability to eat and swallow
• Reduced halitosis and oral hygiene issues
• Better overall energy levels

Social and Psychological Benefits:

• Increased confidence in social situations
• Reduced anxiety about recurrent illness
• Improved family dynamics due to less illness stress
• Enhanced work or school performance

Sleep-Related Improvements

For patients with obstructive sleep apnea, tonsillectomy can provide transformative benefits affecting multiple aspects of health and functioning.

Objective Sleep Parameter Improvements

Measurement	Pre-Surgery	Post-Surgery	Improvement
Apnea-Hypopnea Index	15-45 events/hour	2-8 events/hour	70-85% reduction
Oxygen Saturation	85-92% minimum	92-96% minimum	Significant increase

Adult Benefits:

• Decreased daytime sleepiness
• Improved work productivity
• Better mood and reduced depression
• Enhanced cognitive function
• Reduced cardiovascular risks

Impact on Immune Function

Contrary to historical concerns, modern research demonstrates that tonsillectomy doesn’t compromise overall immune function.

Immune System Adaptation

The immune system possesses remarkable redundancy, with other lymphoid tissues compensating for tonsil removal:

• Adenoids and lingual tonsils remain functional
• Cervical lymph nodes increase activity
• Systemic immune responses remain intact
• No increased susceptibility to infections

Potential Immune Benefits

Some patients experience improved immune function following tonsillectomy:

• Elimination of chronic inflammatory focus
• Reduced systemic inflammation markers
• Better response to vaccines
• Decreased autoimmune complications

Considerations for Tonsillar Regrowth

Partial tonsillar tissue regrowth can occur, particularly in children, though clinically significant regrowth is uncommon.

Factors Influencing Regrowth

• Surgical technique completeness
• Patient age at time of surgery
• Individual healing characteristics
• Presence of remaining lymphoid tissue

Clinical Significance

Most regrowth remains asymptomatic and doesn’t require intervention. Rarely, significant regrowth may recreate original symptoms, potentially necessitating revision surgery.

Long-Term Developmental Considerations

Pediatric Growth Patterns:

• Improved weight gain in previously failure-to-thrive children
• Enhanced linear growth following sleep improvement
• Better dental and facial development
• Normalized eating behaviors

Adult Productivity Measures:

• Increased work attendance and performance
• Reduced healthcare utilization
• Improved relationship satisfaction
• Enhanced overall life satisfaction scores

• Coblation tonsil reduction

5 common questions many people ask about “why do people get their tonsils removed?”

1. Why do people get their tonsils removed?
People get their tonsils removed, a procedure called a tonsillectomy, primarily to treat recurrent or chronic tonsillitis (frequent throat infections), sleep apnea caused by enlarged tonsils, or other complications such as difficulty breathing or swallowing.

2. What conditions typically lead to tonsil removal?
The most common reasons include:

• Recurrent tonsillitis (usually 5-7 or more episodes in a year)
• Chronic tonsillitis that does not respond to antibiotics
• Obstructive sleep apnea due to enlarged tonsils
• Peritonsillar abscess (a painful collection of pus near the tonsils)
• Difficulty swallowing or breathing caused by enlarged tonsils

3. Is tonsil removal a common surgery?
Yes, tonsillectomy is one of the most common surgical procedures, especially in children. It is generally safe and effective for improving quality of life when tonsil problems are severe or persistent.

4. What are the benefits of having tonsils removed?
Removing the tonsils can reduce the frequency and severity of throat infections, improve breathing and sleep quality, and prevent complications related to chronic tonsil problems, such as abscess formation or difficulty swallowing.

5. Are there risks or side effects associated with tonsillectomy?
Like any surgery, tonsillectomy carries risks such as bleeding, infection, pain, and reactions to anesthesia. Recovery usually takes about 1-2 weeks. Most people recover fully and experience significant relief from symptoms after the procedure.

 

Conclusion

Tonsillectomy represents a well-established surgical intervention that provides significant benefits for carefully selected patients suffering from recurrent tonsillitis, obstructive sleep apnea, or other tonsillar-related disorders. The decision to proceed with surgery requires thorough evaluation of symptoms, failed conservative treatments, and individual patient factors that influence both surgical risks and potential benefits.

Modern surgical techniques and perioperative care have significantly improved safety profiles while maintaining excellent therapeutic outcomes. Patients who meet established criteria for surgery typically experience substantial improvements in quality of life, reduced illness frequency, better sleep quality, and enhanced overall health status. The procedure’s success depends largely on appropriate patient selection, skilled surgical technique, and comprehensive postoperative care.

Healthcare providers emphasize the importance of individualized decision-making that considers each patient’s unique circumstances, symptoms severity, treatment response history, and personal preferences. While tonsillectomy offers remarkable benefits for appropriate candidates, the decision should always involve careful consultation with qualified ENT specialists who can provide expert guidance based on current medical evidence and clinical expertise.

For patients and families considering tonsillectomy, understanding the complete process from initial evaluation through long-term outcomes enables informed participation in treatment decisions. With proper preparation, skilled surgical care, and attentive recovery management, tonsillectomy continues to provide life-changing benefits for those suffering from chronic tonsillar problems.

2. Sleep-Disordered Breathing (SDB) and Obstructive Sleep Apnea (OSA)

This is now the most common reason for tonsillectomy in children. Enlarged tonsils and adenoids can block the upper airway during sleep, causing snoring, pauses in breathing (apnea), and poor sleep quality. This can lead to daytime sleepiness, behavioral problems, and even cardiovascular issues if left untreated.

3. Other, Less Common Indications

While infection and sleep apnea are the main drivers, there are other important reasons for tonsillectomy.

Evidence 1: Peritonsillar Abscess (Quinsy)

A peritonsillar abscess is a collection of pus that forms behind one of the tonsils. It is extremely painful and can be a medical emergency. Tonsillectomy is often recommended to prevent it from happening again.
