Abstract |
Introduction |
Endoscopically assisted malarplasty with a greenstick fracture is a method for preserving the body eminence and improving arch protrusion. However, this technique is inadequate when malar body reduction is required. To compensate for these limitations, we developed a new surgical technique using the endoscope to reduce body protrusion.
Material and methods |
We enrolled 261 patients who visited our clinic for zygoma reduction from January 2017 to December 2018. Their mean age was 31 (range 17–63) years. After a scalp incision, an incomplete osteotomy was created from the most prominent portion of the zygoma body to the zygomaticomaxillary suture line. A complete osteotomy was performed on the arch. These osteotomies resulted in an L-shaped zygoma segment after tapping the bone with a mallet.
Results |
Of the 261 patients who underwent our L-rotation technique, 242 also received a corticotomy. Of those patients, 15 underwent a different degree of zygoma reduction on both sides. A floating zygomatic segment occurred in four cases, although no further surgery was required. One patient's zygomatic segment dropped on one side, requiring rigid fixation through the intraoral approach. Most patients were satisfied and there were no specific complications.
Conclusions |
Endoscopically assisted malarplasty using an L-rotation technique enables the protrusion of both the arch and body to be reduced. The zygoma reduction can be modified based on the location of the incomplete osteotomoy line and the number of corticotomies required.
