Objectives/Hypothesis To describe indications, management, and outcomes of endoscopic CO 2 laser cricopharyngeal myotomy (CPM). Study Design Case series with chart review. Methods All patients treated with endoscopic CO 2 laser CPM over a 6‐year period were identified. A retrospective chart review was performed for surgical indication, history and physical examinations, and swallow evaluations. Swallowing outcomes were assessed using the Functional Outcome Swallowing Scale (FOSS); findings were compared across groups. Results Eighty‐seven patients underwent endoscopic CO 2 laser CPM during the study period for cricopharyngeal dysfunction. Indications included Zenker's diverticulum (ZD) (39), DiGeorge syndrome (two), stroke (five), nerve injury (two), radiation for head and neck cancer (15), idiopathic (16), hyperfunctional tracheoesophageal speech (five) and dysphagia from cricopharyngeus stricture after laryngectomy (three). Mean, median, and mode time to feeding postoperatively were 1.4, 1, and 0 days respectively. Mean, median, and mode hospital stays were 1.8, 1, and 1 day respectively. Overall, FOSS scores improved from 2.6 to 1.6 ( P < .001). Improvement was greatest for patients with ZD (2.4 to 1.0) and cricopharyngeal dysfunction from nerve injury (3.3 to 1.8) and least for those with prior radiation (3.9 to 3.2). All patients undergoing CPM for poor tracheoesophageal speech regained speech postoperatively. No patients developed mediastinitis, abscess, or fistula. Conclusions Endoscopic CO 2 laser CPM is a safe treatment for cricopharyngeal dysfunction of various causes, though swallowing outcomes may vary depending on the surgical indication. Early feeding postoperatively after CPM is safe and facilitates early hospital discharge. Level of Evidence 4. Laryngoscope , 124:950–954, 2014
