The aim of this study was to compare two kinds of reduction malarplasty in terms of their bony consolidation. Patients that underwent reduction malarplasty were reviewed retrospectively. The medial movement of the zygomatic body and the zygomatic arch as well as the complications and satisfaction of patients were investigated. The surgical procedure entailed a classical or modified L-shaped osteotomy through intraoral and sideburn approaches. Two groups were distinguished, those for whom a mortice and tenon joint was formed on the zygomatic arch (Group I), and those that formed end-to-end bone contact (Group II). All the cases in Group I showed an improved facial contour with sufficient bone contact. A larger medial movement of the zygomatic arch was observed in Group I (4.54 ± 0.41 mm) than in Group II (2.72 ± 0.29 mm) (P = 0.016). More bone malunion was observed in six cases of Group II (P = 0.030) and four required a second operation. In conclusion, this study indicates that the mortice and tenon approach is preferable when the priority is bony consolidation.
本研究的目的是比较两种颧骨缩小整形术在骨愈合方面的情况。对接受颧骨缩小整形术的患者进行回顾性分析。研究颧骨体和颧弓的向内移动情况以及患者的并发症和满意度。手术采用经口内和鬓角入路的经典或改良L形截骨术。分为两组，一组在颧弓上形成榫卯关节（I组），另一组形成端端骨接触（II组）。I组所有病例面部轮廓均有改善，骨接触良好。I组颧弓向内移动距离（4.54±0.41mm）大于II组（2.72±0.29mm）（P = 0.016）。II组有6例出现更多骨愈合不良情况（P = 0.030），4例需要二次手术。总之，本研究表明，当优先考虑骨愈合时，榫卯入路更可取。
