Modified approach for pediatric external cricopharyngeal myotomy.Int J Pediatr Otorhinolaryngol. 2018 Feb; 105:111-114.IJ
Pediatric cricopharyngeal achalasia is an uncommon but important cause of oropharyngeal dysphagia. Failure of upper esophageal sphincter relaxation is the currently understood pathophysiology. Therapies include balloon dilation, botulinum toxin injection, and endoscopic or open cricopharyngeal myotomy (CPM). Open CPM is usually performed at the posterior midline of the cricopharyngeus and can be a risky procedure given concern for esophageal perforation and damage to the recurrent laryngeal nerve. Here, we present a novel modified technique for open CPM using a superficial anterolateral transection approach in the case of a young male with refractory cricopharyngeal achalasia.
