Genioglossus advancement is a surgical procedure used to treat obstructive sleep apnea (OSA). It involves repositioning the genioglossus muscle, which is the primary muscle responsible for tongue movement, forward to prevent it from collapsing into the airway during sleep. This results in an increased airway size and improved airflow, reducing the occurrence of sleep apnea episodes. The procedure is typically performed through a hidden incision in the mouth.
