The present study aimed to introduce an accurate, less morbid and less time-consuming approach that secures the stability of the condylar movement's range for treating recurrent TMJ dislocations.
Five patients were treated by surgical implantation of bilateral patient-specific titanium onlay eminoplasties; each implant was virtually designed using specific software and milled from grade V titanium blocks. Intraoperatively, each implant was fixed with three mini-screws along the lateral aspect of the zygomatic arch.
The follow-up period ranged from 6 months to 1 year, which targeted the assessment of the maximal incisal mouth opening (MIO). The mean preoperative maximal incisal mouth opening figured (47.8 mm) vs (33.2 mm) for that recorded postoperatively. One patient reported postoperative slight unilateral pain that was gradually diminished through the first postoperative month.
The innovated patient-specific titanium eminoplasty represents an accurate alternative for treatment of chronic recurrent TMJ dislocation.
本研究旨在介绍一种准确、微创且耗时较短的方法，以确保髁突运动范围的稳定性，从而治疗复发性颞下颌关节脱位。
5 名患者接受了双侧患者特异性钛质颧骨板成形术的手术植入治疗；每个植入物均使用特定软件虚拟设计，并从 5 级钛块铣削而成。术中，每个植入物均通过颧弓外侧的 3 个微型螺钉固定。
随访时间为 6 个月至 1 年，旨在评估最大开口度（MIO）。术前最大开口度平均值为（47.8mm），术后记录为（33.2mm）。1 名患者报告术后出现轻微单侧疼痛，在术后第一个月逐渐减轻。
创新的患者特异性钛颧骨板成形术是治疗慢性复发性颞下颌关节脱位的一种准确替代方法。
