Résumé

Radiation therapy (XRT) for laryngeal cancers causes acute and chronic vocal dysfunction. Although these deleterious effects of XRT are well-established, there is a dearth of research with respect to effective voice rehabilitation following XRT for laryngeal cancers. To obtain preliminary data on the efficacy of voice rehabilitation, using vocal function exercises (VFEs) in improving vocal function in adults irradiated for laryngeal cancer. The comparison treatment group (VH) received vocal hygiene counseling. Randomized clinical trial. Participants were randomized to the VFE + VH or VH group. Both interventions lasted 6 weeks. The primary outcome measure was improvement in VHI scores. Secondary outcome measures included auditory-perceptual assessments, acoustic and aerodynamic measures, and laryngeal imaging. Ten participants were recruited for the study. The VFE + VH (n = 6) group demonstrated a statistically significant improvement in the primary outcome measure (P = 0.03), as well as select parameters of all secondary outcome measures. The VH (n = 4) group did not demonstrate a statistically significant improvement in primary or secondary outcome measures. This study offers preliminary data for the utility of VFEs in the irradiated laryngeal cancer population. However, findings in the VFE + VH group lack generalizability, secondary to sample heterogeneity, and limited sample size.

BACKGROUND BACKGROUND
Radiation therapy (XRT) for laryngeal cancers causes acute and chronic vocal dysfunction. Although these deleterious effects of XRT are well-established, there is a dearth of research with respect to effective voice rehabilitation following XRT for laryngeal cancers.
OBJECTIVE OBJECTIVE
To obtain preliminary data on the efficacy of voice rehabilitation, using vocal function exercises (VFEs) in improving vocal function in adults irradiated for laryngeal cancer. The comparison treatment group (VH) received vocal hygiene counseling.
STUDY DESIGN METHODS
Randomized clinical trial.
METHODS METHODS
Participants were randomized to the VFE + VH or VH group. Both interventions lasted 6 weeks. The primary outcome measure was improvement in VHI scores. Secondary outcome measures included auditory-perceptual assessments, acoustic and aerodynamic measures, and laryngeal imaging.
RESULTS RESULTS
Ten participants were recruited for the study. The VFE + VH (n = 6) group demonstrated a statistically significant improvement in the primary outcome measure (P = 0.03), as well as select parameters of all secondary outcome measures. The VH (n = 4) group did not demonstrate a statistically significant improvement in primary or secondary outcome measures.
CONCLUSIONS CONCLUSIONS
This study offers preliminary data for the utility of VFEs in the irradiated laryngeal cancer population. However, findings in the VFE + VH group lack generalizability, secondary to sample heterogeneity, and limited sample size.
