This study was designed to evaluate the feasibility and safety of screw-based semi-rigid intermaxillary fixation (IMF) combined with a specially designed occlusal splint in the conservative treatment of paediatric mandibular condylar fractures. Thirteen paediatric patients with 20 sides of condylar fractures treated with semi-rigid IMF were analyzed retrospectively. Semi-rigid IMF was achieved by inserting self-drilling IMF screws into the anterior alveolar bone of the maxilla and mandible suspended with elastic bands. An occlusal splint with a molar fulcrum was used for functional repositioning of the condylar fragment. After 4 weeks, the screws and occlusal splint were removed. During a mean period of 28.6 months' follow-up, the patients' maximal mouth opening increased to a mean of 37.69 mm. Clinical and radiological examinations revealed satisfactory results in facial symmetry and condylar remodelling. No clinical symptoms or radiographic evidence showed dental injuries associated with screw insertion. This study suggests that this method might be a safe, easy, and effective management of paediatric condylar fractures.
本研究旨在评估基于螺钉的半刚性颌间固定（IMF）联合特制咬合夹板在儿童下颌骨髁突骨折保守治疗中的可行性和安全性。回顾性分析了 13 例儿童 20 侧髁突骨折患者采用半刚性 IMF 治疗的资料。半刚性 IMF 通过将自攻 IMF 螺钉插入上颌和下颌的前牙槽骨中，并悬挂弹性带来实现。使用带有磨牙支抗的咬合夹板对髁突骨折块进行功能复位。4 周后，取出螺钉和咬合夹板。在平均 28.6 个月的随访期间，患者的最大张口度增加至平均 37.69mm。临床和影像学检查显示面部对称性和髁突改建的结果令人满意。没有临床症状或影像学证据表明与螺钉插入相关的牙齿损伤。本研究表明，该方法可能是治疗儿童髁突骨折的一种安全、简便、有效的方法。
