To compare open reduction with internal fixation of mandibular subcondylar fracture with closed reduction in terms of adequate mouth opening.
The randomised clinical trial was conducted from March 2014 to February 2015 at the Oral and Maxillofacial Surgery Department, King Edward Medical University and Allied Hospitals, Lahore, Pakistan, and comprised patients who presented with unilateral subcondylar fractures. The patients were randomly divided into 2 groups. Group-A patients were treated with closed reduction and immobilisation and were discharged the same day, while Group-B patients were treated by open reduction with internal fixation and retained in ward for 1 day. Both were recalled for periodic follow-ups, and were compared in terms of achieving adequate mouth opening. Data was analysed using SPSS 20.
Of the 70 patients, 35(50%) were in each of the two groups. The mean age in Group-A was 28.88±11.86 years compared to 28.22±10.80 years in Group-B (p>0.05). Mean mouth opening in the two groups were consistently positive, and significant at the last two follow ups(p<0.001).
The difference in results of both treatment modalities was significant, indicating that open reduction and internal fixation should be the preferred treatment.
比较下颌髁突骨折切开复位内固定术与闭合复位术在实现充分开口度方面的效果。
这项随机临床试验于2014年3月至2015年2月在巴基斯坦拉合尔爱德华国王医科大学及附属医院口腔颌面外科进行，纳入单侧髁突骨折患者。患者被随机分为两组。A组患者接受闭合复位及固定治疗，当天出院；而B组患者接受切开复位内固定治疗，住院1天。两组患者均被召回进行定期随访，并比较实现充分开口度的情况。使用SPSS 20对数据进行分析。
70例患者中，两组各有35例（50%）。A组平均年龄为28.88±11.86岁，B组为28.22±10.80岁（p>0.05）。两组的平均开口度始终为正值，且在最后两次随访时具有显著性差异（p<0.001）。
两种治疗方式的结果差异显著，表明切开复位内固定术应作为首选治疗方法。
