Combined laryngeal framework surgery and cricopharyngeal muscle-origin transection: a novel effective surgery for dysphagia with pharyngolaryngeal palsy and cricopharyngeal dysfunction under local anesthesia.

Abstract

Cricopharyngeal myotomy and laryngeal framework surgery can improve swallowing function in patients with severe dysphagia. We developed a novel surgical technique for severe dysphagia associated with pharyngolaryngeal paralysis and cricopharyngeal dysfunction, performed under local anesthesia, and investigated its effectiveness. We included nine patients who underwent cricopharyngeal muscle-origin transection with laryngeal framework surgery through a horizontal skin incision under local anesthesia. All patients demonstrated significant improvement in the Food Intake LEVEL Scale without complications. Thus, this surgical technique may serve as a useful and less invasive treatment option for patients with severe dysphagia.
