This study describes a hitherto unreported, functionally distinct craniomandibular muscle as observed in 25 cadaveric specimens and MRI scans of clinical patients. The muscle was consistently observed as originating from the maxillary surface of the sphenoid bone and inserting on the temporal crest (internal oblique line) of the mandible. This anatomic observation should broaden our understanding of craniomandibular function and may have clinical implications regarding retro-orbital pain.
本研究描述了在25个尸体标本和临床患者的MRI扫描中观察到的一种迄今未报道的、功能独特的颅下颌肌肉。该肌肉始终被观察到起自蝶骨的上颌面，止于下颌骨的颞嵴（内斜线）。这一解剖学观察结果应能拓宽我们对颅下颌功能的理解，并可能对视后疼痛具有临床意义。
