ABSTRACT
Upper airway resistance syndrome (UARS) andOSAS encompass a spectrumof sleeprelated upper airway obstruction collectively referred to as SDB. Ifmedical therapy has been unsuccessful, surgical therapy is a therapeutic option. A preoperative assessment estimates the areas of the upper airway thatmay be causing obstruction. Base of tongue collapse may be a component of this obstruction. The surgical armamentarium of procedures to improve the posterior airway space (PAS) includes the mandibular osteotomy with GA. The practice parameters for the surgical treatment of obstructive sleep apnea published by the American Academy of Sleep Medicine states that ‘‘of the procedures directed at enlarging the retrolingual region, inferior sagittal mandibular osteotomy and genioglossus advancment with or without hyoid mytomy and suspension appears to be the most promising’’ (1).
