Objective: This study aimed to analyze the treatment for mandibular coracoid fractures retrospectively.
Methods: A retrospective study on 37 patients with mandibular coracoid fractures treated at Department of Traumatic and Plastic Surgery, West China Hospital of Stomatology, Sichuan University from January 2010 to December 2015 was conducted. Eleven patients were treated conservatively, and 26 patients underwent surgical restoration and internal fixation. Mouth opening and pain degree were used as indicators to analyze treatment results.
Results: The 37 cases of coracoid fractures accounted for 3.18% of the total mandibular fractures. The average age of patients was 38.05 years. Satisfactory results were obtained in both treatments. A considerable change in the degree of mouth opening before and after 6 months was found in the two groups. The pain degree before treatment and 1 day after operation, 1 day and 4 weeks after operation, and 4 weeks and 6 months after operation indicated that the two groups did not significantly differ. However, substantial changes between the two groups were found before treatment and 6 months after operation.
Conclusions: Conservative treatment is recommended for patients with linear, temporalis muscle-located, and non-displaced coracoid fractures. Surgical treatment is recommended for patients with large fractures and those with accompanying zygomatic arch and mandible fractures.
目的 回顾性研究下颌骨喙突骨折治疗方法的选择。方法 选取四川大学华西口腔医院创伤与整形外科2010年1月—2015年12月收治的37例下颌骨喙突骨折患者，其中11例进行保守治疗，26例进行手术复位内固定。通过开口度及疼痛度作为指标来分析治疗效果。结果 37例喙突骨折占全部下颌骨骨折的3.18%，平均年龄38.05岁；两种治疗都取得了满意的效果。两组患者治疗前和治疗后6个月最大开口度有明显变化（P<0.05）。两组患者治疗前和治疗后1 d、治疗后1 d和4周、治疗后4周与6个月相比变化不明显，其他时间相比都有明显变化。结论 对颞肌内、线性、无移位的喙突骨折建议采取保守治疗，对骨折移位较大、影响张口、伴有面中份或面下份骨折的患者建议采取手术治疗。.
