Botulinum toxin A injection of UES in schizencephaly with dysphagia: Case report

초록

A 4-year-old schizencephaly patient admitted to authors' institution with dysphagia caused by upper esophageal sphincter (UES) dysfunction. Videofluoroscopic swallowing study (VFSS) was done for the diagnosis and the botulinum toxin type A (BTX-A) was injected to the cricopharyngeal muscle. UES dysfunction improved and oral feeding was possible after the injection. This normal swallowing function remained for over 79 months which was confirmed by follow up VFSS. To the best of our knowledge, this is first case of schizencephaly patient to be treated by BTX-A for UES dysfunction and longest to maintain its effect with single session of injection.
