Abstract
Background
The use of tracheoesophageal speech with voice prosthesis (T-E speech) after total laryngectomy has increased recently as a method of vocalization following laryngeal cancer. Previous research has not investigated the relationship between quality of life (QOL) and phonatory function in those using T-E speech. This study aimed to demonstrate the relationship between phonatory function and both comprehensive health-related QOL and QOL related to speech in people using T-E speech.
Methods
The subjects of the study were 20 male patients using T-E speech after total laryngectomy. At a visit to our clinic, the subjects underwent a phonatory function test and completed three questionnaires: the MOS 8-Item Short-Form Health Survey (SF-8), the Voice Handicap Index-10 (VHI-10), and the Voice-Related Quality of Life (V-RQOL) Measure.
Results
A significant correlation was observed between the physical component summary (PCS), a summary score of SF-8, and VHI-10. Additionally, a significant correlation was observed between the SF-8 mental component summary (MCS) and both VHI-10 and VRQOL. Significant correlations were also observed between voice intensity in the phonatory function test and both VHI-10 and V-RQOL. Finally, voice intensity was significantly correlated with the SF-8 PCS.
Conclusions
QOL questionnaires and phonatory function tests showed that, in people using T-E speech after total laryngectomy, voice intensity was correlated with comprehensive QOL, including physical and mental health. This finding suggests that voice intensity can be used as a performance index for speech rehabilitation.
