Abstract：

In 1993, the Stanford Phase 1 and 2 Sleep Surgery Protocol for upper airway reconstruction in patients with obstructive sleep apnea (OSA) was published. The cornerstone of this protocol is maxillomandibular advancement (MMA). MMA is a multi-level surgery. It increases intraoral and pharyngeal volume. Via drug-induced sleep endoscopy (DISE), it has shown to result in stability and patency of the velum and lateral pharyngeal wall. Its effect on the tongue is less predictable. While classically reserved as Phase 2 for persistent OSA after phase 1 treatment (palate and tongue base surgery), it can often be first-line for patients with concomitant dentofacial deformity. Today at Stanford, MMA is commonly combined with classic and contemporary treatment modalities, ranging from CPAP to hypoglossal nerve stimulation. Like other interventions for OSA, proper patient selection and precise surgical execution are key to success. The contemporary Stanford experience, as it would apply to the Taiwanese patients today, will be shared in this presentation.
