Head, neck, face, and ear pains are commonly associated with disorders of the temporomandibular joint (TMJ). Several theories have been proposed regarding the functional relationship of the TMJ and the associated structures, and how they might contribute to certain painful conditions. This study was conducted to determine the anatomic relationship of the auriculotemporal nerve to the middle meningeal artery and the mandibular condyle. Forty human cadaver temporomandibular joints were dissected to locate the precise position of the auriculotemporal nerve to the mandibular condyle. The study findings revealed a significant variation in the relationship of the auriculotemporal nerve to the middle meningeal artery. The auriculotemporal nerve was found to be between 10-13 mm inferior to the superior surface of the condyle and 1-2 mm posterior to the neck of the condyle. The nerve was not found to be in a position that would likely create an entrapment with adjacent tissues. These findings may assist the clinician to locate the most appropriate injection site for an auriculotemporal nerve block.
头部、颈部、面部和耳部疼痛通常与颞下颌关节（TMJ）紊乱有关。关于颞下颌关节及其相关结构的功能关系，以及它们如何导致某些疼痛状况，已经提出了几种理论。本研究旨在确定耳颞神经与脑膜中动脉和下颌髁突的解剖关系。解剖了40个成人尸体颞下颌关节，以确定耳颞神经相对于下颌髁突的精确位置。研究结果显示，耳颞神经与脑膜中动脉的关系存在显著差异。发现耳颞神经位于髁突上表面下方10 - 13毫米处，髁突颈部后方1 - 2毫米处。未发现该神经处于可能与相邻组织形成卡压的位置。这些发现可能有助于临床医生确定耳颞神经阻滞最合适的注射部位。
