The impact of vocal rehabilitation on quality of life and voice handicap in patients with total laryngectomy

Abstract

Background: Health?related quality of life (HRQL) and voice handicap index (VHI) of laryngectomies seem to be relevant regarding voice rehabilitation. The aim of this study is to assess the impact on HRQL and VHI of laryngectomies, following voice rehabilitation. Materials and Methods: A retrospective study done at the Ear, Nose, and Throat Department of the Emergency County Hospital. Sixty?five laryngectomees were included in this study, of which 62 of them underwent voice rehabilitation. Voice handicap and QOL were assessed using the QOL questionnaires developed by the European Organisation for Research and Treatment of Cancer (EORTC); variables used were functional
scales (physical, role, cognitive, emotional, and social), symptom scales (fatigue, pain, and nausea and vomiting), global QOL scale (pain,swallowing, senses, speech, social eating, social contact, and sexuality), and the functional, physical, and emotional aspects of the voice handicap (one?way ANOVA test). Results: The mean age of the patients was 59.22 (standard deviation = 9.00) years. A total of 26 (40%) patients had moderate VHI (between 31 and 60) and 39 (60%) patients had severe VHI (higher than 61). Results of the HRQL questionnaires showed that patients who underwent speech therapy obtained better scores in most scales (P = 0.000). Patients with esophageal voice had a high score for functional scales compared with or without other voice rehabilitation methods (P = 0.07), and the VHI score for transesophageal
prosthesis was improved after an adjustment period. The global health status and VHI scores showed a statistically significant correlation between speaker groups. Conclusion: The EORTC and the VHI questionnaires offer more information regarding life after laryngectomy.
