Paradoxical vocal cord motion (PVCM) is a condition characterized by inappropriate adduction of the vocal cords during respiration. Usually seen in children and adolescents, PVCM presentation in infants is uncommon. Once thought to be a product of psychiatric disease, there are now several other proposed etiologies including irritant-induced and secondary to neurologic disease. Previous studies showed that the treatment of gastric reflux in this age group leads to a resolution of symptoms. We present a case of PVCM in an infant with hydrocephalus and Chiari II malformation. She received reflux therapy and ventriculoperitoneal (VP) shunting with two revisions. Despite these interventions, she continued with symptoms and eventually progressed to bilateral vocal cord paralysis (VCP). There is a paucity of literature describing PVCM as a precursor to VCP. Clinicians should be aware that in this population, refractory PVCM may serve as a warning sign for further vocal cord function decline.
矛盾性声带运动（PVCM）是一种在呼吸时声带出现不适当内收为特征的病症。通常见于儿童和青少年，在婴儿中出现PVCM并不常见。PVCM曾被认为是精神疾病的产物，现在有几种其他提出的病因，包括刺激物诱发以及继发于神经系统疾病。先前的研究表明，该年龄组胃食管反流的治疗可使症状缓解。我们报告一例患有脑积水和Chiari II畸形的婴儿发生PVCM的病例。她接受了反流治疗以及脑室腹腔（VP）分流术并进行了两次翻修。尽管进行了这些干预，她仍持续出现症状，最终发展为双侧声带麻痹（VCP）。描述PVCM作为VCP先兆的文献很少。临床医生应意识到，在这一人群中，难治性PVCM可能是声带功能进一步下降的警示信号。
