Bifid mandibular condyle is an infrequent and normally asymptomatic morphological alteration of the mandibular condyle. Although the underlying cause is not clear, a number of theories have been proposed, including teratogenic effects in the embryo, vascular alterations during condyle development, and condylar remodeling following fracture. Since Schier first described this anomaly in 1948 in live individuals, further cases have been documented in the literature. We present a new case of bilateral bifid condyle. The disorder was asymptomatic and constituted a casual finding in a young male presenting for the surgical extraction of two impacted molars.
双侧下颌髁突裂是一种罕见的、通常无症状的下颌髁突形态改变。尽管其潜在病因尚不清楚，但已提出了多种理论，包括胚胎期的致畸作用、髁突发育过程中的血管改变以及骨折后的髁突重塑。自1948年Schier首次在活体中描述这种异常以来，文献中已有更多病例记载。我们报告一例双侧髁突裂的新病例。该疾病无症状，是一名年轻男性在因手术拔除两颗阻生磨牙就诊时偶然发现的。
