The surgical treatment of obstructive sleep apnea

Obstructive sleep apnea is a highly prevalent disorder that significantly increases mortality when it is moderate to severe. Continuous positive airway pressure (CPAP) provides excellent relief to sleep apnea in the majority of patients. Unfortunately, many patients cannot tolerate CPAP and seek surgical alternatives. The reported surgical success rates range between 25 and 100% with most studies achieving a 50-70% success rate. The severity of the sleep apnea, as well as the patient's physical features influence the surgical success rate. Patients with mild sleep apnea should be treated if systematic. Treatment should be encouraged for patients with moderate to severe sleep apnea because of the decrease in life expectancy and other associated morbidities. Current surgical procedures include uvulopalatopharyngoplasty, genioglossus advancement, radiofrequency ablation to the base of tongue, tongue suspension, maxillomandibular advancement, and tracheostomy.
