Objective:
Age-related vocal atrophy (ARVA) negatively impacts voice and quality of life (QOL). This study aims to determine utility-based QOL in ARVA patients, correlate findings with traditional patient-reported outcome measures (PROMs), and generate utility-based inferences.
Methods:
Forty ARVA patients were prospectively recruited from a tertiary care center. Health utility was measured using standard gamble, time trade-off, and visual analog scale, assessing participants' current health states relative to defined comparison states (blindness/death). Traditional PROMs (Voice Handicap Index-10 [VHI-10] and Voice-Related Quality of Life Scale [V-RQOL]) were also collected. Descriptive and paired statistics were performed to determine health utility, and Pearson correlation assessed the association between PROMs and health utilities.
Results:
Mean health utility in ARVA was 0.84 ± 0.22, 0.88 ± 0.17, and 0.62 ± 0.25 using standard gamble, time trade-off, and visual analog scale, respectively. There were positive correlations between V-RQOL and time trade-off (r = 0.66; p < 0.0001) as well as with standard gamble (r = 0.47; p = 0.002). Participants with ARVA reported no difference in health utility impact between their voice impairment and monocular blindness (Mean dif 10.9; 95% CI -1.6, 23.5; p = 0.101). Patients with ARVA were willing to part with an average 4.6 ± 6.1 years of life to restore normal voice.
Conclusions:
ARVA patients view their voice impairment as a significant health decrement, comparable to monocular blindness. These findings underscore the substantial impact of ARVA on QOL and highlight the need for continued research and new therapies.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
