Group:

The domestic temporomandibular joint arthroscopy surgery team

Sample size:

干预措施:

在全麻下采用关节镜双穿刺技术,通过颞下颌关节镜与射频消融电极,在颞下颌关节上腔,将前、外侧附着表面的滑膜及韧带切开,然后将前附着“撕开”,注意保护自前上斜向外下走行的咬肌神经及内侧的翼静脉丛,直至内侧韧带彻底松解,使关节盘自如地覆盖髁突;用钝头闭孔器压住关节盘双板区,使关节盘保持在复位的状态,于关节盘后带与双板区交界处,直接穿透关节盘,植入1颗复位钉,复位钉植入髁突的位置位于髁突外后方距髁突顶点下 8mm处。手术后即刻开始戴用软颌垫两周到三周。

干预措施代码:

Intervention:

Under general anesthesia, the temporomandibular joint (TMJ) arthroscopy was performed using a double-puncture technique. The synovium and ligaments on the anterior and lateral attachments within the upper joint space were incised using the TMJ arthroscope and radiofrequency ablation electrode. The anterior attachment was then "torn open", with careful attention to preserving the masseteric nerve (which runs anterosuperiorly to inferolaterally) and the medial pterygoid venous plexus. The dissection continued until the medial ligament was fully released, allowing the articular disc to freely cover the condyle. A blunt-tipped obturator was used to compress the bilaminar zone (posterior attachment), maintaining the disc in a reduced position. A repositioning anchor was then inserted by penetrating the articular disc at the junction of the posterior band and bilaminar zone. The anchor was placed in the posterolateral aspect of the condyle, 8 mm below the condylar apex. Postoperatively, a soft occlusal splint was immediately applied and worn for two to three weeks.

指标中文名:

手术术野的视野清晰度

指标类型:

主要指标

Outcome:

Visualization quality of the surgical field

Type:

Primary indicator

测量时间点:

测量方法:

外科医生使用数字评分量表对视野清晰度进行评分,用视觉模拟评分(VAS)评估手术过程中解剖结构的可视化难易程度,0分表示完全缺乏可视化,10分表示可视化完全无障碍。

Measure time point of outcome:

Measure method:

The visual clarity of the surgical field was scored by surgeons using a numerical rating system. The difficulty of visualizing anatomical structures was simultaneously evaluated with a Visual Analogue Scale (VAS), where 0 denoted absolute visualization failure and 10 corresponded to perfect, unobstructed visualization throughout the procedure.

指标中文名:

测量时间点:

手术结束后 2小时±15分钟、术后 24小时±4小时、术后 72小时±12小时

测量方法:

采用疼痛视觉模拟评分(VAS)标准观察受试者的疼痛评分。采用 10分制,分数越高代表疼痛程度越强。

Measure time point of outcome:

2 h (+/-15 min) postoperatively, 24 h (+/-4 h) post-operation, 72 h (+/-12 h) after surgery

Measure method:

The Visual Analogue Scale (VAS; 0-10) was administered to quantify pain intensity, with scale anchors defined as 0 (no pain) to 10 (worst imaginable pain).

Measure time point of outcome:

from the operative day until 30 days postoperatively

Measure method:

All complications adjudicated as Clavien-Dindo grade ≥III that were either attributable to or possibly associated with the device, captured from initial surgical incision until postoperative day 30. Outcome adjudication followed the standard Clavien-Dindo classification system.
