Modified genioglossus advancement with radiofrequency tongue base reduction for retroglossal collapse in Obstructive sleep apnea patients

To study the combined effect of modified genioglossus advancement (MGGA) and radiofrequency tongue base reduction (RFTBR) a long with anterolateral advancement (ALA) pharyngolplasty on OSA patients with retrolingual airway collapse. Prospective clinical study. Zagazig and Benha Universities Medical Hospitals. Twenty-one patients (21)with multilevel OSA underwent modified genioglossus advancement with radiofrequency tongue base reduction and anterolateral advancement pharyngolplasty. All patients were assessed before and 6 months after surgery by history talking, clinical examination, Epworth Sleepiness Scale evaluation fiberoptic examination during muller's maneuver, drug induced sleep endoscopy (DISE), panoramic X-ray, Cephalometry and polysomnography. Postoperative mean ± SD Epworth Sleepiness Scale (ESS) significantly decreased from 18.86 ± 2.03to 8.19 ± 1.86 (P-value was
