The surgical therapy of Obstructive Sleep Apnea (OSA) requires addressing anatomical obstructions or collapse of the pharyngeal airway by skeletal and soft tissue surgeries. Numerous surgical options have been documented for OSA therapy with varying success. OSA surgery is vital when patients refuse continuous positive airway pressure (CPAP). The aim of this article is to review surgeries for OSA and the effectiveness of each surgery in terms of Epworth sleepiness scale(ESS), Apnea Hypopnea Index (AHI) or Respiratory Disturbance Index (RDI) reduction. © 2020 Elsevier B.V., All rights reserved.
