目的：观察大年龄儿童肌性斜颈的手术疗效。方法：手术治疗肌性斜颈患儿49例，对大年龄患儿部分切除胸锁乳突肌远端。对22例手术时年龄＞7岁（平均11岁8个月）者随访1年以上（平均3年4个月）。结果：所有患儿的功能和外观均有改善，但有些病儿后遗脊柱侧凸畸形，尤其是女孩。结论：大年龄儿童尤其女孩可继发脊柱畸形。 Objective: To observe the operative effect of muscular torticollis in older children. Methods: Forty-nine children with muscular torticollis were treated surgically, and the distal part of the sternocleidomastoid was resected. Twenty-two patients, aged> 7 years (average 11 years and 8 months) at the time of surgery, were followed up for more than 1 year (average 3 years and 4 months). Results: All children had improved function and appearance, but some had delayed scoliosis, especially in girls. Conclusions: Large age children, especially girls, may have secondary deformities.
