【摘要】 目的探讨单侧外伤性骨性颞下颌关节强直伴内侧髁突残存的手术治疗方法及疗效。方法南昌大学附属口腔医院2010—2016年收治的内侧有髁突残存的外伤性颞下颌关节强直10例10侧关节纳入研究,采用外侧成形术+颞肌筋膜瓣进行治疗。通过临床和CBCT随访,评价该治疗方法疗效,采用SPSS18.0软件包对术前术后最大开口度的变化进行统计学分析。结果术后随访3—12个月,10例患者无一例关节复发,开口度改善显著(P<0.05)。结论外侧成形术保留了残存的关节结构,与颞肌筋膜瓣结合,可以很好地预防颞下颌关节强直复发。更多还原

【Abstract】 Objective To investigate the surgical method for traumatic temporomandibular joint(TMJ)ankylosis with medially displaced residual condyle.Methods From 2010 to 2016,10 patients with TMJ ankylosis and medially displaced residual condyle(10 joints)were treated with lateral arthroplasty(LAP)and temporalis myofascial flap(TMF).The curative efficacy was evaluated by postoperative CBCT and clinical follow-up.SPSS 18.0 software package was used to analyze the improvement in maximal mouth opening.Results All patients were followed up for 3-12 months.No recurrence was found and the maximal incisal opening was significantly improved in all patients(P<0.05).Conclusion LAP can reserve the residual TMJ structure.The combined treatment with LAP and TMF can effectively prevent the recurrence of TMJ ankylosis.更多还原
