Perceptual Voice and Speech Analysis after Supraglottic Laryngeal Closure for Chronic Aspiration in Head and Neck Cancer.

Objectives/hypothesis: To evaluate the voice and speech outcomes after tubed supraglottic laryngeal closure (TSLC) surgery to treat chronic aspiration after radiotherapy for head and neck cancer.

Study Design: A retrospective case-control study.

Methods: The data of patients who underwent radiotherapy for head and neck cancer and who later required total laryngectomy or TSLC for chronic aspiration between 2004 and 2017 were retrieved from a dysphagia clinic.
