微型钛板在内固定治疗下颌骨粉碎性骨折中的应用:21例临床分析

目的:研究微型钛板内固定术在治疗下颌骨粉碎性骨折中的应用价值.方法:选择2017年3月-2018年2月沈阳市口腔医院收治的下颌骨粉碎性骨折患者21例.所有患者均给予微型钛板坚固内固定,分别在患者下颌骨下缘、上缘、外皮质中部进行固定.观察术后骨折愈合情况及不良反应发生情况.结果:术后3个月内,所有患者均达到骨性愈合,平均时长为(1.53±0.36)个月.21例患者中,6例(28.57%)出现轻微咬合不正,1例(4.76%)发生局部感染,未出现微型钛板断裂、持续疼痛、开口受限、牙损伤、面神经损伤及骨不连患者.结论:微型钛板内固定术适用于无骨缺损的下颌骨粉碎性骨折患者,具有术后骨折愈合良好、时间短、不良反应少的优点.

Internal fixation of mandibular comminuted fracture with mini-titanium plate: a retrospective study of 21 cases

PURPOSE: To investigate the value of internal fixation in management of mandibular comminuted fracture with mini-titanium plate. METHODS: Twenty-one patients with mandibular comminuted fracture treated in Stomatology Hospital of Shenyang from March 2017 to February 2018 were enrolled, the patients received internal fixation with mini-titanium plate. The lower mandibular margin, upper mandibular margin and middle outer cortex were fixed respectively. The postoperative fracture healing and adverse reactions were recorded and analyzed. RESULTS: All patients achieved bone healing within 3 months after surgery, with an average duration of (1.53±0.36) months. Among 21 patients, six patients (28.57%) had minimal occlusion, and 1 patient (4.76%) had local infection. No microtitanium plate fracture, persistent pain, limited mouth opening, tooth injury, facial nerve injury or nonunion were found. CONCLUSIONS: Internal fixation with mini-titanium for comminuted mandibular fracture patients without bone defects has the advantages of good postoperative fracture healing, short healing time and few adverse reactions.
