Abstract

The first priority to solve the sleep-disordered breathing could be soft-tissue surgery or non-surgical therapy such as continuous positive airway pressure (CPAP). However, in patients with incomplete remission or relapse, the sleep quality and day time symptoms may persist. The case report presented a young man with main problems of obstructive sleep apnea (OSA) and Skeletal Class II maxillary protrusion. We proposed a segmental maxillomandibular rotational advancement (SMMRA) with surgery-first procedure at the end of his puberty. The surgical orthodontic treatment achieved good outcome of function and esthetics at the same time. The polysomnogrphic data and airway dimension were dramatically improved without jeopardize the facial profile of the patient.
