Hyperfunction of the upper esophageal sphincter (UES) can cause severe dysphagia. This condition referred as cricopharyngeal dysphagia may occur after head and neck surgery due to altered muscle spasm and stenosis of the pharyngo-esophageal segment. Among various treatment options available, Botulinum toxin A (Botox) injection offers a nonsurgical treatment which is useful especially for debilitated patients, and there has been a recent increase in the clinical use of Botox by otolaryngologists for managing such conditions. A 55-year-old male with base of tongue (BOT) cancer suffered from severe dysphagia after total glossectomy and neck dissection treatment. Videofluoroscopic swallow study (VFSS) and flexible endoscopic evaluation of swallowing (FEES) showed inability to pass food through the UES due to cricopharyngeal spasm. After injection of 10 U of Bot ox into each cricopharyngeus muscles (total 20 U) via EMG-guided percutaneous injection, swallowing function had improved and oral nutrition was possible, with food passing through the UES visualized on VFSS and FEES.
