The purpose of the present study was to evaluate the clinical application of resorbable and nonresorbable plates for correction of facial asymmetry.
A total of 272 patients who had undergone orthognathic surgery were enrolled. The site of osteotomy was fixed using a nonresorbable plate in group I (n = 152) and using a resorbable plate in group II (n = 120). The postoperative complications included postoperative anterior open bite, infection, temporomandibular joint dysfunction, and postoperative relapse. The incidence of all complications was examined.
The surgical outcome was successful in 269 patients (98.89%). Of the 152 patients with a titanium plate, 13 (8.6%) developed complications. Of the 120 patients with a resorbable plate, 22 (18.3%) developed complications. A greater degree of postoperative open bite and a trend toward relapse were observed in patients' cases in which an absorbable fixation plate was used. Postoperative infection occurred in patients with an absorbable fixation plate.
On the basis of these data, we have concluded that an absorbable fixation plate should be used instead of a titanium fixation plate in indicated patients.
本研究旨在评估可吸收板和不可吸收板在矫正面部不对称中的临床应用。
共纳入272例行正颌手术的患者。I组（n = 152）使用不可吸收板固定截骨部位，II组（n = 120）使用可吸收板。术后并发症包括术后前牙开合、感染、颞下颌关节功能障碍和术后复发。检查所有并发症的发生率。
269例患者（98.89%）手术结果成功。在152例使用钛板的患者中，13例（8.6%）出现并发症。在120例使用可吸收板的患者中，22例（18.3%）出现并发症。在使用可吸收固定板的患者病例中，观察到术后开合程度更大且有复发趋势。可吸收固定板患者发生术后感染。
基于这些数据，我们得出结论，在特定患者中应使用可吸收固定板而非钛固定板。
