摘要:

目的:介绍改良耳屏内切口颞下颌关节盘锚固术手术方法并评估其临床疗效。方法:对 2017 年 2 月—2021 年10 月期间我院收治的 264 例(328 侧关节)中晚期颞下颌关节盘不可复性前移位(anterior disc displacement without reduction,ADDWoR)患者,采用改良耳屏内切口行颞下颌关节盘锚固术。具体方法为:通过改良耳屏内切口手术入路,依次分离颞浅筋膜、颞深筋膜浅层及关节囊,在颧弓根部切开关节囊,暴露关节盘,使用 1 颗 Mini Mitek 锚固钉固定在髁突后下极,采用 2 条 Orthocord 缝线进行水平褥式缝合,将前移的关节盘进行复位。术前及术后 7 d 内行颞下颌关节磁共振成像(magnetic resonance imaging,MRI) 检查,术后 3 个月复查 MRI 评价关节复位情况,记录患者术后1 周、1 个月、3 个月张口度,采用视觉疼痛模拟评分法(visual analogue scale,VAS)记录患者术后 3 个月颞下颌关节疼痛缓解情况,温哥华瘢痕量表评估患者术后 3 个月术区瘢痕情况。结果:术后 3 个月 MRI 评价显示,306 侧(249 例)关节复位疗效评价为“优”,20 侧(14 例)关节复位疗效评价为“良”,2 侧(1 例)关节复位疗效为“差”,成功复位率为 99.39%(326/328 侧);仅有 1 例患者术后关节复位疗效评价为“差”,占 0.61%(2/328 侧)。术后 3 个月复诊,所有患者张口受限均改善,疼痛评分小于 2 分,瘢痕评价小于 3 分。结论:改良耳屏内切口位置隐蔽,颞下颌关节盘复位效果良好,是一种可推广的颞下颌关节盘锚固术手术入路。

Abstract: Objective: To introduce the surgical technique of temporomandibular joint disc anchoring through a modified tragus incision. Methods: From February 2017 to October 2021, 264 patients (328 sides of joints) with advanced anterior disc displacement without reduction (ADDWoR) admitted to our hospital were treated with temporomandibular joint disc anchorage using a modified tragus approach. The specific method was as follows: Use a modified intraauricular approach to separate the superficial temporal fascia and the deep and superficial layers of the deep temporal fascia, as well as the joint capsule, cut the joint capsule at the root of the zygomatic arch, expose the joint disc, using a Mini Mitek anchor screw to fix it at the posterior and lower pole of the condylar process, and using two Orthocor sutures for horizontal mattress suture to reposition the anterior displaced joint disc. Magnetic resonance imaging (MRI) of the temporomandibular joint was performed before and within 7 days after surgery. The facial nerve condition was observed from 1 to 7 days after surgery, follow-up MRI was performed 3 months after surgery, and the mouth opening degree was recorded at 1 week, 1 month, and 3 months after surgery. The visual analog scale (VAS) was used to record the relief of temporomandibular joint pain in patients at 3 months after surgery. The vancouver scar scale was used to evaluate the scar condition in the surgical area at 3 months after surgery. Results: According to the evaluation of postoperative MRI, 306 joints (249 cases) were evaluated as "excellent", 20 joints (14 cases) were evaluated as "good", and 2 joints (one case) were evaluated as "poor". The successful reduction rate was 99.39% (326/328 sides). Only one patient evaluated as "poor" after surgery, accounting for 0.61% (2/328 sides). At the 3-month follow-up after surgery, all patients showed improvement in limited mouth opening, with pain scores below 2 and scar evaluations below 3. Conclusion: Improving the concealed position of the incision inside the tragus and achieving good results in the reduction of the temporomandibular joint disc is a widely applicable surgical approach for temporomandibular joint disc anchoring.
