In sagittal split ramus osteotomy (SSRO) surgery, variable methods are used to maintain the proximal segment in the anatomic position during fixation to minimize early built-in relapse. However, there is still a chance of condyle malposition.In this study, a new titanium plate, which has a sliding oval hole in its distal part, was used to enable postoperative mobility of the proximal segment. This plate makes it possible to reposition the condyle during the postoperative intermaxillary fixation period.These plates were used successfully in 23 patients who received SSRO setback surgery. All of the patients were followed up without any complications, including early relapse or temporomandibular joint problems.The authors used a new plate that enables sliding of the proximal segment after SSRO, which can minimize early relapse without any postoperative complications.
在矢状劈开下颌支截骨术（SSRO）中，在固定过程中会采用多种方法将近端骨段维持在解剖位置，以尽量减少早期的内置性复发。然而，髁突错位仍有发生的可能。在本研究中，一种新型钛板被用于术后近端骨段的活动，该钛板在其远端有一个滑动椭圆形孔。这种钛板使得在术后颌间固定期能够重新定位髁突。这些钛板成功应用于23例接受SSRO后退手术的患者。所有患者均获随访，未出现任何并发症，包括早期复发或颞下颌关节问题。作者使用了一种新型钛板，可在SSRO术后实现近端骨段的滑动，从而在无任何术后并发症的情况下将早期复发降至最低。
