A suture enlocation (SE) approach is proposed to manage comminuted intra-articular mandibular condyle fractures not amenable to open reduction internal fixation approaches. The SE approach is an effective operative option for the treatment of condylar fractures with the combination of fracture dislocation, malocclusion, comminution, and inadequate surface area for open fixation techniques. This study describes the SE approach, outcomes, and complications. The SE technique is described, and the health records of patients treated with the SE approach are reviewed. Outcome data were collected for diet, interincisal opening, occlusion, pain, and complications. The SE approach involves reducing the fractured condylar fragment using a hole drilled through the fragment to secure it to the periosteum with a polydioxanone suture. This allows the reduced fragment to be managed as a nondisplaced fracture with mandibulomaxillary fixation and class 2 elastics. A chart review involving 8 patients (11 condyles) illustrates the outcomes of the SE approach from 2006 to 2021. Age at the time of injury ranged from 12 to 51 years and the follow up ranged from 2 to 68 months. At final follow up, 7 patients were eating a regular diet, 7 had normal interincisal opening, 4 had normal occlusion, and 4 reported ongoing mandibular discomfort. Failure of fixation occurred in 1 case, which required further operative management. The SE technique shows promise as an effective way to reduce fracture components, manage occlusion, and facilitate secondary bone healing in comminuted and displaced mandibular condyle fractures.
提出一种缝线内固定(SE)方法来处理不适用于切开复位内固定方法的粉碎性关节内下颌髁突骨折。SE方法是治疗伴有骨折脱位、错牙合、粉碎以及切开固定技术可用表面积不足的髁突骨折的一种有效手术选择。本研究描述了SE方法、结果及并发症。描述了SE技术,并回顾了采用SE方法治疗患者的健康记录。收集了饮食、切牙间开口度、咬合、疼痛及并发症方面的结果数据。SE方法包括通过在骨折的髁突碎片上钻孔,用聚二氧六环酮缝线将其固定于骨膜,从而使骨折碎片复位。这使得复位后的碎片可作为无移位骨折,采用下颌骨-上颌骨固定及Ⅱ类弹力牵引进行处理。一项涉及8例患者(11个髁突)的图表回顾展示了2006年至2021年SE方法的治疗结果。受伤时年龄范围为12至51岁,随访时间范围为2至68个月。末次随访时,7例患者饮食正常,7例切牙间开口度正常,4例咬合正常,4例报告下颌仍有不适。1例出现固定失败,需要进一步手术处理。SE技术有望成为一种有效复位骨折块、处理咬合及促进粉碎性移位下颌髁突骨折二期骨愈合的方法。
