내시경적 보툴리눔 독소 주입으로 치료한 윤상인두근이상증 1예

Abstract

Botulinum toxin has been used to treat various gastrointestinal tract diseases such as achalasia, diabetic gastroparesis, sphincter of oddi dysfunction, and chronic anal fissures. Recently, it has also been used for the treatment of cricopharyngeal muscle dysfunction. Several studies have reported that botulinum toxin injections may be a safe and effective treatment. Previously, cricopharyngeal muscle dysfunction was treated by mechanical balloon dilation or cricopharyngeal myotomy. Here, we report a case of a 57-year-old man who presented with cricopharyngeal dysphagia due to cerebral infarction and who was successfully treated with endoscopic botulinum toxin injection
