Abstract：
The purpose of this study was to assess the effects of protecting the facial nerve with a modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint which allows an excellent operative field of visualization, multiple surgical procedures of the temporomandibular joint, and general care which improves the immediate postoperative period, making this a less morbid surgery. This study included 33 patients (39 sides) who underwent surgical treatment for disorders of the temporomandibular joint from the years 2021 to 2023 at the maxillofacial department of the clinic \"Colsanitas\" located in Bogota, Colombia. Therapeutic results were evaluated by postoperative facial nerve injury, with the House-Brackman scale; every patient was examined for adequate facial musculature function immediately after surgery. Notably, zero patients presented facial nerve injury. These results imply that the modified endaural approach with a peripheral dissection of the superficial musculoaponeurotic system to access the temporomandibular joint reduces the incidence of facial nerve injuries, improves operative site exposure, and lowers the frequency of complications.
摘要：
这项研究的目的是评估通过改良的耳内入路保护面神经的效果，并对浅表肌肉腱膜系统进行外周解剖，以进入颞下颌关节，从而获得出色的手术视野。颞下颌关节的多种外科手术，和改善术后即刻的一般护理，让这个手术变得不那么病态.这项研究包括33名患者（39侧），他们从2021年到2023年在位于波哥大的诊所“Colsanitas”的颌面部部门接受了颞下颌关节疾病的手术治疗，哥伦比亚。通过术后面神经损伤评估治疗效果，使用House-Brackman量表；手术后立即检查每位患者的面部肌肉组织功能。值得注意的是,零患者出现面神经损伤。这些结果表明，改良的耳内方法与浅表肌肉腱膜系统的外周解剖以进入颞下颌关节减少了面神经损伤的发生率，改善手术部位暴露，并降低并发症的发生频率。
