In this paper, an archaeological case of unilateral bifid mandibular condyle is presented. This uncommon anomaly is characterized by a division of the mandibular condylar head. In this case, the left condyle was divided into two articulating surfaces oriented mediolaterally; two articular facets on the anterior wall of the glenoid fossa for the double condyle were observed. The morphological and radiological analysis do not show any evidence of injuries or degenerative pathology. Taking into account the two main causes of bifid condyle suggested in the literature (traumatic and developmental), an embryopathy by teratogenic agents is proposed as a possible aetiology of the bifid condyle reported here.
本文介绍了一例单侧下颌髁突裂的考古学病例。这种罕见的异常表现为下颌髁突头部的分裂。在该病例中，左侧髁突被分为两个呈内外侧排列的关节面；观察到关节盂前壁上有两个用于双髁突的关节面。形态学和放射学分析未显示任何损伤或退行性病变的迹象。考虑到文献中提出的髁突裂的两个主要原因（创伤性和发育性），本文报道的髁突裂可能病因是致畸剂导致的胚胎病。
