Hyoid myotomy and suspension without simultaneous palate or tongue base surgery for obstructive sleep apnea

Objective: Determine the effects of hyoid myotomy and suspension (HMS) without concurrent palatal or tongue base sleep surgery for obstructive sleep apnea (OSA). Method: Patients with OSA treated with HMS were identified using CPT code (21685) at an academic and private sleep surgery clinic. Those who underwent concurrent palatal or tongue base sleep surgery were excluded. Outcomes included simultaneous procedures, apnea-hypopnea index (AHI), lowest oxyhemoglobin saturation (LSAT), and Epworth Sleepiness Scale (ESS). Results: Nineteen patients with OSA underwent HMS without palatal or tongue base sleep surgery. The average age at surgery was (55.3 ± 13.5) years with a majority of patients being male (71%). Concurrent procedures included the following: torus mandibularis excision (n = 1), endoscopic sinus surgery (n = 4), septoplasty (n = 10), inferior turbinate reduction (n = 12), and nasal valve repair (n = 2). AHI improved significantly from (39.7 ± 21.2) events/h to (22.6 ± 22.7) events/h after HMS (P 30 events/h) had an improvement in AHI from (49.9 ± 16.6) events/h to (29.1 ± 24.9) events/h, P
