PURPOSE
Attachments of the medial capsule of the temporomandibular joint (TMJ) to structures other than the medial fossa wall are thought to exist and to have functional significance. This study evaluated these relationships.
MATERIALS AND METHODS
The anatomic relationships between the medial capsule and other medial structures, the sphenomandibular ligament, discomalleolar ligament, and auriculotemporal nerve, were examined in 14 cadaver heads.
RESULTS
The results showed that the sphenomandibular ligament attaches separately from the medial capsule of the TMJ and therefore has no functional significance to the biomechanics of the joint. The discomalleolar ligament was found to be a continuation of the retrodiscal tissues and minimally associated with the medial capsule. The auriculotemporal nerve was not found to be in a relationship with the medial aspect of the condyle to the extent that mechanical irritation is possible during TMJ movement or disc displacement.
目的
颞下颌关节（TMJ）内侧关节囊与内侧窝壁以外结构的附着被认为是存在的且具有功能意义。本研究评估了这些关系。
材料与方法
在14个尸头上检查了内侧关节囊与其他内侧结构、蝶下颌韧带、盘锤韧带和耳颞神经之间的解剖关系。
结果
结果表明，蝶下颌韧带与颞下颌关节内侧关节囊分开附着，因此对关节的生物力学没有功能意义。发现盘锤韧带是盘后组织的延续，与内侧关节囊的关联极小。未发现耳颞神经与髁突内侧有在颞下颌关节运动或盘移位时可能产生机械刺激的关系。
