Tonsillectomy and adenoidectomy, though less frequently performed now than in the 1930s, remain among the most common surgical procedures in the United States. The need for and benefits of tonsillectomy and adenoidectomy have been a source of controversy for several decades. Nonetheless, there are situations in which these procedures definitely are beneficial. Tonsillectomy and adenoidectomy are two distinct procedures with separate indications, and they are performed concurrently only when the specific indications for each coexist. Tonsillectomy is indicated by recurrent tonsillitis, peritonsillar abscess, chronic tonsillitis, tonsillar neoplasm, or tonsillar hypertrophy that is obstructive to the upper aerodigestive tract (respiratory distress, dysphagia, or interference with performance of an adenoidectomy). Adenoidectomy is indicated for nasal airway obstruction due to adenoidal enlargement from hypertrophic or inflammatory processes. Although correlation exists among obstructive adenoids, mouth breathing, and dentofacial anomalies, present evidence is not sufficient to justify adenoidectomy solely on the basis of craniofacial or dentofacial abnormalities. Today, elimination of an occult source of infection (once called focal infection) in patients with disorders such as rheumatic fever or serous otitis media is not a valid indication for either operation. Contraindications to tonsillectomy and adenoidectomy include bleeding disorders, familial anesthetic intolerance, velopharyngeal insufficiency, and concurrent disease that may enhance operative risks. Like all surgical procedures, tonsillectomy and adenoidectomy entail morbidity and risk of mortality. The most frequent complication of these operations is hemorrhage. Risk of mortality is approximately 0.006%. Mortality and morbidity can be minimized by appropriate preoperative evaluation, complete control of the airway with endotracheal anesthesia, and meticulous surgical technique.

Tonsillectomy for improvement of dysphagia in children is well recognized, but its effects upon deglutition in the neurologically impaired child have not been described. A review was performed of pre- and post-operative oral-pharyngeal motility (OPM) studies obtained on 15 children (aged 1-10 years; mean 4.6 years) with neurologically-based dysphagia who underwent tonsillectomy for upper airway obstruction (13) or recurrent tonsillitis (2). Each OPM study was rated independently by two trained observers for the presence or absence of 13 features of deglutition. Subjects served as their own control in comparative analysis. There was a mean improvement of 4.33 features of deglutition (mode: 4, range: -1(-)+7) following tonsillectomy. Of 10 children with pre-existing laryngeal penetration or aspiration, two had partial resolution and five had complete resolution following surgery. Post-operatively, two children developed new laryngeal penetration with one also having aspiration. The inter-observer reliability for the OPM study interpretation was 0.90. We conclude that tonsillectomy has a role in the neurologically impaired child with dysphagia, but a pre-operative OPM study is indicated to identify silent aspiration and to aid in necessary counseling for the possibility of a deterioration of deglutition following surgery.

Adenotonsillar disease (adenoiditis and recurrent tonsillitis) is a prevalent otolaryngologic disorder aetiologically based on chronic inflammation triggered by a persistent bacterial infection. These bacteria, mostly Staphylococcus aureus, Haemophilus sp., and Streptococcus sp., persist predominantly intracellular and within mucosal biofilms. The recurrent or chronic inflammation of the adenoids and faucial tonsils leads to chronic activation of the cell-mediated and humoral immune response, resulting in hypertrophy of the lymphoid tonsillar tissue. This hypertrophic tissue is the cause for the prominent clinical symptoms: obstruction of the upper airways, snoring, and sleep apnea for adenoiditis or sore throat, dysphagia and halitosis for recurrent tonsillitis. Treatment strategies should target the persisting bacteria within their biofilm or intracellular shelter. Macrolide antibiotics like clarithromycin are able to modulate the immune system and to interfere in bacterial signaling within biofilms. Clindamycin, quinupristin-dalfopristin, and oritavancin are intracellular high active compounds. Surgical removal of the hypertrophic tissue by modern procedures like laser tonsil ablation, eliminates not only a mechanical obstacle of the airways, it removes also the basis for the aetiologic cause, the "biofilm carrier". This review summarizes the role of bacterial persistence in mucosal biofilms for the aetiology, diagnosis and treatment of adenotonsillar disease and relevant patents.
