Abstract/OtherAbstract:
BACKGROUND: Reduction malarplasty via an intraoral approach for correction of a prominent malar complex is quite popular in the Orient. However, one point of fixation in the anterior zygoma body area, the most widely used method, sometimes is insufficient and likely to result in malunion and cheek drooping. We designed a new assisted fixation technique to strengthen the effect of fixation. METHODS: Two parallel oblique vertical ostectomies were performed on the zygomatic body with a groove left in the inner osteotomy line. The zygomatic arch root was cut obliquely through a small sideburn incision just in front of articular tubercle, medial to lateral and anterior to posterior. The freed malar complex was medially and superiorly repositioned with the zygomatic body wedged in the groove, followed by fixation with one miniplate or wire. Finally, the periosteum in the zygomatic area was pulled and sutured to the deep temporal fascia. RESULTS: Most patients were satisfied with their results. No inferiorly displaced malunion occurred in the zygomatic body. There were no serious complications such as nonunion or permanent facial nerve injury. Minor complications, including palpable step-off, mild asymmetry, hematoma, and mild cheek drooping, occurred in some cases. CONCLUSION: Our assisted fixation method, combined with subperiosteal lifting, can provide ideal effects and sufficient fixation in malar reduction to prevent many complications such as malunion and cheek drooping.
