| Surgical treatment options are plentiful; they include tonsillectomy with uvulopalatopharyngoplasty (tonsillectomy/UPPP), genioglossus advancement, hyoid suspension, palatal advancement or stiffening, and tracheostomy. Some of these patients underwent genioglossus advancement and/or hyoid suspension. Among the possible causes of upper airway obstruction are the posterior displacement of a normal-sized tongue secondary to micrognathia and/or retrognathia, the loss of support of the genioglossus muscle, and negative pressure in the pharynx during swallowing and inspiration. |
