Feasibility of 2-Point Fixation by Absorbable Plates Using the Transoral Approach in Management of the Zygomatic Complex Fractures.

ABSTRACT

PURPOSE: The purpose of this study was to retrospectively evaluate the feasibility of 2-point fixation using absorbable plates by the transoral approach in the management of the zygomatic complex (ZMC) fractures. METHODS: Twenty-five patients (15 male and 10 female, age range 16 y to 55 y) with Knight and North Group Ⅲ zygomatic fractures were included in this case series. Open reduction by intraoral approach was performed on these patients, and the fractures were fixed using absorbable plates placed at the zygomaticomaxillary buttress and infraorbital rim. Postoperatively, follow-up was undertaken to evaluate the fracture healing, mouth opening, facial asymmetry, diplopia, and paresthesia. RESULTS: Postoperatively, all patients achieved uneventful healing; facial symmetry and wound healing were achieved, along with sensory recovery involving the infraorbital nerve. Complications such as sensory disturbances, infection, diplopia, malunion, and nonunion were not encountered in these patients. CONCLUSIONS: Two-point fixation using absorbable plates by transoral approach can provide sufficient stabilization for Knight and North Group III zygomatic fractures.
