Tonsillectomy and OSAs
In the adult population, tonsillectomy is the appropriate first line treatment in select patients (Epstein 2009, Evidence Based Clinical Guideline). After thorough examination, if the primary site of obstruction is hypertrophied tonsils, tonsillectomy has been shown to be a very effective treatment regardless of the severity of the OSA (Verse 2000, Level 3). While most of the articles supporting adult tonsillectomy for OSA are small, the results of these 7 articles strongly support this treatment. In Verse 2000, many of the studies prior to 2000 are reviewed. In this review, patients had a mean preoperative Apnea-Hypopnea Index (AHI) of 54.6 and mean post operative AHI of 3.6.
Surgical treatment of pediatric sleep disordered breathing with tonsillectomy and adenoidectomy is the recommended first line treatment. In the pediatric population, resolution of OSA occurs in 82% of patients who are treated with T&A. (Brietzke 2006, Meta-analysis) The effects of T&A include normalization of AHI, improvement of quality of life (QOL) measures, improved behavior, improved academic performance, and improved neurocognitive functioning. In snoring pediatric patients with symptoms of sleep disordered breathing in whom AHI is not normalized postoperatively, or in whom AHI was not elevated preoperatively, significant improvement are seen in all QOL measures, neurocognitive functioning and behavior (Chervin 2006,Level 2 evidence).
The clinical practice guideline for tonsillectomy in children (Roland, 2011), developed by the AAO-HNS in 2011, defines SDB as abnormalities of respiratory pattern or the adequacy of ventilation during sleep, which include snoring, mouth breathing, and pauses in breathing. SDB encompasses a spectrum of obstructive disorders that increases in severity from primary snoring to obstructive sleep apnea (OSA). Daytime symptoms associated with SDB may include excessive sleepiness, inattention, poor concentration, and hyperactivity (Marcus 2012). Children have been shown to have significant improvement in these symptoms with tonsillectomy and adenoidectomy (Chervin 2006).
