Congenital muscular torticollis results from shortening or excessive contraction of the sternocleidomastoid (SCM) muscle. The reported incidence varies between 0.4 and 1.9%. Various theories have been proposed, but its true aetiology remains obscure. The deformity is characterized by a practically painless, contracted cordlike SCM muscle, which pulls the head toward the side affected, narrows and draws the shoulder upward, forcing the chin in the opposite direction. Torticollis of congenital origin is a deformity not commonly met with in the practice of maxillofacial surgery. The rarity, lack of, or inadequacy of the previous treatment, together with the advanced age and marked deformity appear to warrant an investigation and report of the outcome. A case of congenital muscular torticollis is presented who reported at the age of 18 years and has been successfully treated by unipolar SCM release.
先天性肌性斜颈是由胸锁乳突肌（SCM）缩短或过度收缩引起的。报道的发病率在0.4%至1.9%之间。人们提出了各种理论，但其真正病因仍不清楚。该畸形的特征是胸锁乳突肌实际上无痛、呈条索状收缩，将头部拉向患侧，使肩部变窄并向上牵拉，迫使下巴转向相反方向。先天性斜颈是颌面外科实践中不常见的畸形。由于以往治疗的罕见性、缺乏或不足，再加上患者年龄较大和明显畸形，似乎有必要对治疗结果进行调查并报告。本文介绍了一例18岁就诊的先天性肌性斜颈病例，该病例已通过单极胸锁乳突肌松解术成功治疗。
