Botulinum Toxin Injection for Postlaryngectomy esophageal speech failure and Achalasia
보툴리눔독소를 이용한 후두전적출술후 식도발성장애 및 식도이완불능증의 치료
Abstract
Persistent pharygoesophageal spasm has been demonstrated to be responsible for poor speech rehabilitation after laryngectomy Management of these patients has included bougienage and pharyngeal neurectomy. Achalasia is a disorder of swallowing in which the lower esophageal sphincter fails to relax. Botulinum toxin injection of the upper esophageal sphincter or lower esophageal sphincter has been successfully used diagnostically and therapeutically for esophageal speech failure or achalasia. So, we report the use of botulinum toxin, a paralytic agent, for the treatment of these conditions.
