Application of the Bracing System in Reduction Malarplasty in Asian Population.

[BACKGROUND] In the East, a broad and prominent malar is considered to express an aggressive and unpleasing impression; therefore, patients seek to improve their appearance through malar reduction. Although most of the techniques have been greatly improved, still there are some pitfalls in the form of cheek sagging or bone nonunion. In this study, we performed a reduction malarplasty using a firm bracing system to minimize major postoperative complications.

[METHOD] This was a retrospective study evaluating the results of a total of 157 patients (139 women and 18 men) who underwent reduction malarplasty using a bracing system via intraoral and periauricular. The age of the patients ranged from 17 to 44 with a mean age of 25.3 years. The mean follow-up period was 9.4 months. All patients underwent routine physical and laboratory examinations. Facial photographs in the frontal, oblique, and submentovertical views were taken. Patients with severe facial asymmetry and facial deformities were excluded from the study. Preoperative states and patients' desires were considered. In some patients, combined malarplasty with mandibular angle reduction or genioplasty was performed.

[RESULTS] A total of 157 patients who underwent this modified reduction malarplasty between January 2015 and January 2019 were retrospectively reviewed. Decent postoperative facial stability and satisfactory aesthetic results were realized among all patients. Major complications such as severe asymmetry or bone nonunion were not observed in our patients.

[CONCLUSION] Based on a thorough anatomic understanding of zygoma and masseter action, we modified previous L-shaped reduction malarplasty through constructing a firm bracing system on the malar complex. Satisfactory surgical outcomes were obtained. Our method is an ideal surgical method to effectively reduce the height and width of the zygomatic arch and prevent complications such as bone nonunion and cheek drooping.
