<unk>  also known as<unk>  myotomy and<unk>  or<unk>  advancement, is a surgical procedure or sleep surgery in which the<unk>  bone and its muscle attachments to the tongue and airway are pulled forward with the aim of increasing airway size and improving airway stability in the retrolingual and hypopharyngeal airway (airway behind and below the base of tongue). The horseshoe shaped<unk>  bone sits directly below the base of tongue with the arms of the bone flanking the airway.<unk>  is typically performed as a treatment for obstructive sleep apnea (OSA). This procedure is frequently performed with a uvulopalatopharyngoplasty (UPPP) which targets sites of obstruction higher in the airway. Typically, a<unk>  is considered successful when the patient’s apnea-hypopnea index is significantly reduced after surgery.
