Fractures of the jaw are often treated with rigid and stable internal fixation using plates or miniplates. Early surgery for jaw fractures is the optimal treatment; however, if a late treatment is begun, often the adoption of other protocols is needed. When the jaw fracture has one free bone fragment with 2 full-thickness lesions of mucoperiosteal soft tissues both on the buccal and palatal sides, the risk of resorption or necrosis is very high after elevating a mucoperiosteal flap for rigid fixation. For this reason, we developed an intraoral epimucosal fixation technique using self-locking screws and plates. Substantial advantages of this new technique, in comparison with other commonly used fixation techniques, consisted in the prevention of bone resorption or necrosis by safe and simple screw insertion procedure after manipulation of the fracture for reduction in closed surgery. Major indications for epimucosal fixation in closed surgery are the presence of jaw fractures without dislocation or reducible jaw fractures by manipulation particularly in edentulous patients.
颌骨骨折通常采用钢板或微型钢板进行坚固稳定的内固定治疗。早期进行颌骨骨折手术是最佳治疗方法;然而,如果开始进行延迟治疗,通常需要采用其他方案。当颌骨骨折有一个游离骨块,颊侧和腭侧均有2处全层粘骨膜软组织损伤时,掀起粘骨膜瓣进行坚固内固定后,骨吸收或坏死的风险非常高。因此,我们开发了一种使用自锁螺钉和钢板的口内粘膜上层固定技术。与其他常用固定技术相比,这种新技术的显著优点在于,在闭合手术中对骨折进行复位操作后,通过安全简单的螺钉植入程序可预防骨吸收或坏死。闭合手术中粘膜上层固定的主要适应证是无脱位的颌骨骨折或通过手法可复位的颌骨骨折,尤其是无牙患者。
