Objectives: The aim of this study was to elucidate the utility of the Kano method with surgical closure of the larynx by cricoid cartilage removal in improving quality of life in patients with severe dysphagia and their caregivers. Methods: Nine patients with severe dysphagia who underwent the Kano method were evaluated for oral intake and activities of daily living using the functional oral intake scale and the Barthel index, respectively, as indices of quality of life. Additionally, nutritional status, inflammation, and postoperative complications were assessed. Furthermore, 7 family caregivers were queried regarding frequency of sputum suction, mood of family caregivers, and postoperative satisfaction. Results: Functional oral intake scale and Barthel index scores as well as inflammation improved significantly after surgery ( P < .05). There were no severe complications or other complications requiring surgical intervention. The frequency of sputum suction was reduced postoperatively ( P < .05). The mood of family caregivers was significantly improved and satisfaction level was high postoperatively. Conclusions: Surgical closure of the larynx is an appropriate choice for patients with irreversible severe dysphagia and impaired articulation or vocal function because quality of life is improved for both patients and family caregivers and the satisfaction of family caregivers is sufficient.
