Patients who undergo Phase I procedures make maxillomandibular advancement challenging due to changes in the soft tissue anatomy which can restrict advancement.
We have developed a new treatment protocol to manage the obstructive sleep apnea patient. Patients are first diagnosed with obstructive sleep apnea with a polysomnography study. Once OSA has been diagnosed the patient is placed on a continuous positive airway pressure device to treat the disease. Those patients who cannot tolerate CPAP and wish to explore surgical options undergo a drug induced sleep endoscopy to evaluate the levels of obstruction. Patients either qualify for the Inspire upper airway stimulator or MMA surgery.
MMA surgery is done with a mandible first approach using virtual surgical planning. This allows deviation from the traditional 10mm advancement of the maxilla and mandible. It allows more autrotation of the mandible and is more aesthetic to the patient.
