RESUMO

The complaints between the women are frequent, particularly between the singers, of whom alterations in the voice occur after the menopause. It has been reported, in literature, that woman’ fundamental frequency is altered in this phase of the life. As the vocal fold possess receivers for the sexual steroids are possible that these alterations are decurrent of the observed hypoestrogenism in the climacteric. To compare the voice fundamental frequency (F0) of postmenopausal women, users and non-users of HRT with women in menache. Forty-five patients have been trialed, divided into the following groups: control group (15 women of 20 to 40 years of age, non-users of hormonal contraceptives, non smokers, with regular menstrual cycles), group with HRT (15 women of 45 to 60 years of age, menopaused for over 2 years, users of estradiol valerate 1mg/norgestimato 90mcg for a minimum period of 6 months) and the group without HRT (15 women of 45 to 60 years of age, menopaused for over 2 years, without HRT for a minimum period of 6 months). All patients had been submitted to the otolaryngological evaluation and videolaryngoscopy in order to confirm the integrity of the larynx. Afterwards F0 has been evaluated by emitting the vowels [e] and [i] in the patient’s habitual voice pitch. The F0 was analyzed using the Dr.Speech Pro. 3 software. The ANOVA test was used in order to compare the averages of F0 between the groups. The average ages of the groups control, with HRT and without HRT were respectively 30,3 years, 54,5 years and 56,5 years. The average F0 of the groups control, with HRT and without HRT were respectively: vowel [e]: 215,97Hz; 206,21Hz and 200,71Hz and vowel [i]: 229,89Hz; 221,79Hz and 212,79Hz. The results showed a trend of aggravation of the F0 in postmenopausal women, once the F0 average of the group with HRT was closer to the group control than the group without HRT. However, in a comparison between those three groups, there were no significant statistical difference in the voice F0 for the vowels [e] (p=0,2127) and [i] (p=0,193). There were no differences in F0, in the speaking voice, between women in menache and postmenopausal users and non-users of HRT. However it’s been recorded a trend in the aggravation of F0 in the postmenopausal women, mainly amongst the without HRT users. In accordance with these results seem not to have significant clinical difference in the F0 of the voice said between women in menacme, postmenopausal users and non-users of HRT. The trend the reduction of F0 in the hypoestrogenism patients suggests the possibility of that small decurrent differences of the hormonal influence on the larynx, that they have not been detected in this study, can reach greaters levels of significance when the groups will be analyzed for the sung voice.
