#113 – Dr. Kasey Li – Top sleep surgeon changed his mind on FME

Sleep surgeon Dr. Kasey Li returns to JawHacks three years after his first appearance for an in-depth update on nasomaxillary expansion and maxillomandibular advancement (MMA). Dr. Li developed EASE, a minimally invasive surgical split of the midpalatal suture used alongside an expander. He explains why he now uses the FME in about 95% of his EASE cases, the risks of overexpansion, how FME compares with custom MARPE, and why he sees no value in sleep endoscopy (DISE). The conversation also covers expansion after MMA, the origin of the 10 mm advancement guideline, custom plates, and how MMA affects nasal breathing and aesthetics.
