Abstract
Obstructive sleep apnea syndrome (OSAS) is a common condition that,if left untreated, results in significant health risks. In addition to weight agin, cardiovascular risks, and other medical sequelae. The perferred method of treatment for OSAS is continuous positive airway pressure (CPAP). However, compliance varies but ranges around 50%. Those patients not using CPAP are therefore candidates for surgical intervention. UPPP is a classic common surgical intervention but has limitations. Although reducing obstruction caused by the soft palate and tonsils, UPPP does not improve obstruction of the retroglossal space and the hypopharynx.
Meta- analysis of reported success rates for UPPP hovers around 40%.
These disappointing results led to a wide variety of procedures to alleviate obstruction at the hypopharynx. level, including genioglossus advancement hyoid advancement, partial glossectomy, and maxillary mandibular advancement.Although many of these procedures have shown promise, the complexity of many of these procedures is adisavantage. Radiofrequency tongue base reduction (TBRF) was introduced as a simplified solution to decrease retroglossal space obstruction in OSAS.
This study was conducted on 32 matching patients as regard Age, Sex , BMI and Neck circumference, selected randomly from the Menofia University hospital form Jun. 2007 to Dec. 2008.
These 32 patients were diagnosed as having OSA (byPolysomnography). Under general anaesthesia all procedures were
