Menopause and its Effect on Voice.

ABSTRACT: This study was designed to study the impact of menopause on voice quality. Cross-sectional Observational study with a total of 100 subjects. All subjects underwent biochemical analysis which included thyroid function tests, estrogen levels, progesterone levels and underwent voice analysis using the VAUGHMI voice analyser software. 50 postmenopausal females as cases and 50 premenopausal females as controls were taken for the study. The females were of the age group 35-55 yrs in order to remove age as confounding factor. The primary outcome measure was Total score, calculated based on harshness, hoarseness and breathiness. The postmenopausal females had a poorer voice quality than the premenopausal females (Total score 1.62 vs 2.48, p < 0.001). There was a significant difference between the fundamental frequency and pitch and perturbation in frequency of the postmenopausal females as compared to premenopausal females. The difference in the perturbation in the intensity of the voice was not significant. No linear correlation could be established between the voice quality and oestrogen or progesterone levels but the intergroup variation of the two parameters was significant. The premenopausal females have better voice quality than postmenopausal females. The relationship between hormonal level and voice quality couldn't be established. Further studies are required to assess the relation of hormone levels & voice quality with the possibility of exploring voice cosmesis.

LEVEL OF EVIDENCE: Level 3.
