Various surgical procedures have been used to limit mandibular opening in patients with recurrent dislocations of the temporomandibular joint (TMJ). These include intracapsular injection of sclerosing agents and tethering of the mandible. Other methods include obstruction of the condylar translation by downfracturing the zygomatic arch or by bone graft augmentation of the tuberculum and creating a mechanical impediment using Vitallium mesh or a stainless steel pin.
In this paper, two patients are described in whom the range of condylar movement was restricted by a bone plate attached to the lateral surface of the zygomatic arch. One arm of the plate was extended medially just below the articular eminence. One patient had a hypermobile joint in combination with mitral valve prolapse, and the other patient suffered mental retardation. The surgical technique is described in detail.
Six months postoperatively, TMJ function was unimpeded and there was no recurrence of condylar dislocation.
已采用多种外科手术方法来限制颞下颌关节（TMJ）复发性脱位患者的下颌开口。这些方法包括关节囊内注射硬化剂和下颌骨固定。其他方法包括通过颧弓下骨折或通过结节植骨增加来阻碍髁突平移，并使用维他灵网或不锈钢针制造机械障碍。
本文描述了两名患者，其髁突运动范围通过附着于颧弓外侧表面的骨板受到限制。骨板的一个臂在内侧关节结节下方延伸。一名患者患有活动度过高的关节并伴有二尖瓣脱垂，另一名患者患有智力障碍。详细描述了手术技术。
术后6个月，颞下颌关节功能未受阻碍，髁突脱位未复发。
