Maxillomandibular advancement Surgery in Morbidly Severe Obstructive Sleep Apnea: A 2-year follow-up

Obstructive sleep apnea syndrome is a common disorder characterized by recurrent episodes of upper airway obstruction during sleep. Its prevalence is estimated at 2% to 4% among middle-aged adults (30 to 60 years), while approximately 1% of children are also affected. OSAS is now recognized as an independent risk factor for cardiovascular diseases, highlighting the importance of early diagnosis and appropriate treatment. Polysomnography remains the gold standard for diagnosing obstructive sleep apnea syndrome. Therapeutically, nasal continuous positive airway pressure is considered the first-line treatment for both snoring and obstructive sleep apnea. Oral appliances may be used in mild to moderate cases. However, in severe forms of the condition, especially when associated with craniofacial abnormalities, maxillomandibular advancement is often the only effective option capable of providing long-term improvement. This case report presents the management of a 27-year-old male patient with obstructive sleep apnea syndrome, associated with a significant mandibular retrognathia. The treatment plan involved maxillomandibular advancement, with the objective of increasing the oropharyngeal airway volume. The surgical outcome was favorable, offering a definitive resolution of the patient’s obstructive sleep apnea syndrome.
