The sternomastoid "tumor" of infancy is a firm, fibrous mass, appearing at two to three weeks of age. It may or may not be associated with torticollis. Generally, the "tumor" initially grows, then stabilizes, and in about half the cases recedes spontaneously after a few months. It may leave a residual torticollis or may be associated with a facial or cranial asymmetry of a delayed torticollis. The etiology is unknown, a direct cause and effect relationship to birth trauma has been largely disproved although approximately half these children are products of breech deliveries. The treatment is controversial. Approximately half of these "tumors" will resolve spontaneously without sequelae. Progressive torticollis or development of facial asymmetry are considered indications for surgery. The purpose of this report is to acquaint the head and neck surgeon with this entity which may confront him for diagnosis and treatment.
婴儿期的胸锁乳突肌“肿瘤”是一种质地坚硬的纤维性肿块，出现在两到三周龄时。它可能与斜颈有关，也可能无关。一般来说，该“肿瘤”最初会生长，然后稳定下来，大约半数病例在几个月后会自行消退。它可能会留下残余斜颈，或者与迟发性斜颈导致的面部或颅骨不对称有关。病因不明，尽管这些孩子中约有一半是臀位分娩的产物，但出生创伤与之存在直接因果关系这一说法已基本被否定。治疗存在争议。这些“肿瘤”中约有一半会自行消退且无后遗症。进行性斜颈或面部不对称的发展被视为手术指征。本报告的目的是让头颈外科医生了解这种可能需要其进行诊断和治疗的疾病。
