Conventionally, cricopharyngeal myotomy has been performed by collar incision. We performed endoscopic trans-oral cricopharyngeal myotomies on three cases:cricopharyngeal dilatation insufficiency, Wallenberg syndrome and sporadic inclusion body myositis. Laryngeal elevation and pharyngoplasty were added in the Wallenberg syndrome case. In all cases, there were no serious complications, and the swallowing disorder improved. Compared with the conventional cricopharyngeal myotomy by collar incision, endoscopic trans-oral cricopharyngeal myotomy is less invasive and useful, especially when treating elderly cases. Further adoption and verification of this method are eagerly awaited.
