目的是从常规取出接骨板的角度分析手术治疗下颌角骨折的临床过程，因为这些骨折与并发症和接骨板取出的高发生率相关。受试者为40例单侧下颌角骨折患者，经口内复位，主要用外斜脊上的单个微型钢板固定。在手术过程中，7名患者的第三磨牙与骨折线相关。从接骨板移除、第三磨牙保存和并发症方面评估临床过程。1例患者术后出现伤口感染，2例患者在随访期间发生冠周炎。这些都是通过药物和局部灌溉来管理的。1例保留第三磨牙的患者未进行必要的访视，失访。39例患者在确认骨折愈合良好后取出接骨板，大多数在一年内。32颗保存的第三磨牙中有24颗同时拔除。这些手术通常在门诊局部麻醉下进行，不会引起任何并发症。下颌角骨折手术治疗后常规取出接骨板，同时拔除第三磨牙（如有指征），可能有助于避免日后与接骨板和第三磨牙相关的并发症。
The purpose was to analyze the clinical course of surgically treated mandibular angle fractures from the viewpoint of routine removal of the plate because these fractures are associated with high rates of complications and plate removal. The subjects were 40 patients with unilateral mandibular angle fracture, which was intraorally reduced and principally fixed with a single miniplate on the external oblique ridge. The third molar in relation to the fracture line was extracted in seven patients during the surgery. Clinical course was evaluated in terms of removal of the plate, preservation of the third molar and complications. One patient showed a wound infection postoperatively, and two patients developed pericoronitis during the follow-up. These were managed with medication and local irrigation. One patient with a preserved third molar did not make a required visit and was lost from the follow-up. Removal of the plates was performed in 39 patients after confirmation of good fracture healing, mostly within a year. Twenty-four of 32 preserved third molars were simultaneously extracted. These procedures were generally performed under local anesthesia on an outpatient basis, and they did not cause any complications. Routine removal of the plate after surgical treatment for mandibular angle fractures, simultaneously with extraction of the third molar if indicated, may be beneficial to avoid complications related to the plate and the third molar later in life.
