摘　　要：目的探讨分侧口内外联合法治疗颞下颌关节前脱位的临床效果。方法利用口颌系统姿态肌链平衡理论对颞下颌关节复位过程进行生物力学分析,改进复位手法;运用分侧口内外联合法治疗87例颞下颌关节前脱位患者,对临床效果进行评价。结果分侧口内外联合法可有效避免升颌肌群反射性收缩,提高复位效率;87例患者均成功复位,术程用力轻巧高效,髁突下降指征明确,患者并发症少。结论分侧口内外联合法是一种高效、便捷、微创的颞下颌关节前脱位复位方法,在临床上有一定的推广应用价值。Objective To observe the clinical outcomes of a combined unilateral intraoral and extraoral reduction approach in the treatment of anterior temporomandibular joint (TMJ) dislocation. Methods Postural muscular chains were utilized in the biomechanical analysis of stomatognathic systems for improving TMJ repositioning approaches. A total of 87 patients with anterior TMJ dislocation were included in the present study. A combined unilateral intraoral and extraoral reduction approach was applied, and the clinical effects were evaluated. Results Biomechanical analysis reveal that reflexive contraction of the maxillary muscle group was blocked sufficiently during the combined unilateral intraoral and extraoral reduction process. All dislocated TMJs were set successfully and efficiently with few complications. Conclusion Combined unilateral intraoral and extraoral reduction approach is an effective, convenient, and minimally invasive way to treat anterior TMJ dislocations.
