    Abstract:
    BACKGROUND/OBJECTIVE: The Amatsu tracheoesophageal shunt (ATES) represents a nonprosthesis surgical option for voice restoration in laryngectomized patients. However, data regarding the long-term efficacy of ATES are lacking. STUDY DESIGN: Retrospective, single-institution study. METHODS: Between 2001 and 2010, 16 patients with laryngeal cancer underwent total laryngectomy with ATES at the Hyogo Cancer Center (Akashi, Hyogo, Japan). Of these, 11 achieved long-term tracheoesophageal speech that was maintained for a follow-up exceeding 5 years (range 75-161 months; median 95 months). All patients were male and ranged from 46 to 74 years of age at the time of ATES surgery. RESULTS: Of 11 eligible patients, eight were able to speak intelligibly with ATES at last follow-up. Regarding aspiration, three patients experienced no leakage, and six experienced mild leakage of saliva without medical intervention at last follow-up. Almost all patients maintained an unchanged degree of voice quality (9 of 11) and leakage (8 of 11). CONCLUSION: The favorable voice restoration and low aspiration rates achieved in this study appear to support the long-term efficacy of ATES. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:1395-1397, 2018.
