Mandibular midline distraction (MMD) is a relatively new surgical technique for correction of transverse discrepancies of the mandible. This study assesses the amount and burden of complications in MMD. A retrospective cohort study was performed on patients who underwent MMD between 2002 and 2014. Patients with congenital deformities or a history of radiation therapy in the area of interest were excluded. Patient records were obtained and individually assessed for any complications. Complications were graded using the Clavien-Dindo classification system (CDS). Seventy-three patients were included of which 33 were males and 40 were females. The mean follow-up was 2.1 years. Twenty-nine patients had minor complications, grades I and II. Two patients had a grade IIIa and three patients had a grade IIIb complication. Common complications were pressure ulcers, dehiscence, and (transient) sensory disturbances of the mental nerve. This study shows that although MMD is a relatively safe method, complications can occur. Mostly the complications are mild, transient, and manageable without the need for any reoperation.
下颌骨中线牵张成骨术（MMD）是一种用于矫正下颌骨横向差异的相对较新的外科技术。本研究评估了MMD并发症的数量和负担。对2002年至2014年间接受MMD治疗的患者进行了一项回顾性队列研究。排除了患有先天性畸形或在感兴趣区域有放射治疗史的患者。获取患者记录并对任何并发症进行个体评估。并发症采用Clavien-Dindo分类系统（CDS）进行分级。纳入73例患者，其中男性33例，女性40例。平均随访时间为2.1年。29例患者出现轻度并发症，即I级和II级。2例患者出现IIIa级并发症，3例患者出现IIIb级并发症。常见并发症包括压疮、裂开以及颏神经（短暂的）感觉障碍。本研究表明，尽管MMD是一种相对安全的方法，但仍可能发生并发症。大多数并发症是轻度、短暂的，且无需再次手术即可处理。
