This study assessed the efficacy of the retromandibular antero-parotid approach for open reduction and internal fixation (ORIF) of subcondylar fractures. Sixty patients with the mean age of 31.03 years underwent surgical reduction with a 20-25mm incision in the retromandibular area with an antero-parotid transmasseteric approach. All patients were followed between 6 to 12 months. At the end of the first week, six patients exhibited postoperative malocclusion. At the next visits, all patients had optimal occlusion. Maximal interincisal opening (MIO) of 56 patients (93.3%) was >37mm, and only four patients (6.7%) had MIO<37mm. In three patients (5%), weakness of the buccal branch of the facial nerve was noticed postoperatively. No salivary gland complications were seen. The surgical scar was hardly noticeable. Retromandibular access with transmasseteric antero-parotid approach is the technique of choice for treatment of high- and low-level subcondylar fractures with adequate visibility and direct access to the condylar area.
本研究评估了下颌后窝腮腺前入路用于髁突骨折切开复位内固定(ORIF)的疗效。60例平均年龄为31.03岁的患者采用下颌后窝20 - 25mm切口及腮腺前经咬肌入路进行手术复位。所有患者随访6至12个月。术后第一周结束时,6例患者出现错牙合。在随后的随访中,所有患者均达到了理想的咬合关系。56例患者(93.3%)的最大切牙间开口度(MIO)>37mm,只有4例患者(6.7%)的MIO<37mm。3例患者(5%)术后出现面神经颊支无力。未观察到唾液腺并发症。手术瘢痕几乎不可见。下颌后窝经咬肌腮腺前入路具有足够的视野且能直接进入髁突区域,是治疗高位和低位髁突骨折的首选技术。
