ABSTRACT Introdução: O Fumo é altamente agressivo ao trato vocal e é um dos principais fatores de risco ao câncer de laringe. A fumaça pode levar a irritação do trato vocal, edema em pregas vocais, pigarro, tosse, aumento de secreção e de infecções. Objetivo: Avaliar as dimensões das pregas vocais em idosos fumantes e não fumantes do sexo masculino. Método: Foram estudados 15 cadáveres do sexo masculino, na faixa etária de 60 a 90 anos, sendo 8 não fumantes e 7 fumantes. Para a coleta de dados foram seguidas quatro etapas sequenciais: 1ª) História clínica do cadáver; 2ª) Remoção da laringe; 3ª)Dissecação da laringe e 4ª) Morfometria das dimensões das pregas vocais. Resultados: Não houve diferença estatística significativa quanto à morfologia das dimensões das pregas vocais entre idosos fumantes e não fumantes, sendo o comprimento (p=0,58), largura (p=0,72) e espessura (p=0,65) equivalente entre os dois grupos estudados. Conclusão: Constata-se que macroscopicamente não foi possível encontrar diferenças ocasionadas pelo fumo nas três dimensões das pregas vocais, entretanto, histologicamente, em fumantes, as chances de achados referentes a displasias e neoplasias no tecido das pregas vocais e que causam problemas na qualidade vocal já são comprovadas.

    ABSTRACT: Previous group research has shown that the mean voice-fundamental frequency (F0) for individuals who smoke is lower than that of age- and sex-matched nonsmokers. It is believed that this reduction in F0 is a result of edema of the vocal folds caused by tobacco smoke. This study investigated F0 changes during smoking and no-smoking periods. Data were collected before, during, and after a 40-hour period of no-smoking. Analysis of the voice recordings showed a rise in voice F0 for the two smoking subjects during the 40-hour no-smoking period. Age- and sex-matched control subjects did not show a rise in their F0 during the same tasks. Results suggest that the pitch-lowering effects of cigarette smoking may be reversed after as few as 40 hours of smoking cessation.

    ABSTRACT: The effects of long-term cigarette smoking were examined in a series of phonatory tasks. The results indicated that a significant difference existed between the fundamental frequency of the male smokers and the male nonsmokers in the oral reading and spontaneous speech tasks. Differences between the fo values of the female smokers and nonsmokers in these tasks were not significant, but the same trends were notes. Results of the fo analysis of the sustained vowel phonations were not significant, but showed the same trend; that is, the smokers had lower fundamental frequency values than the nonsmokers.

    ABSTRACT: The human larynx is essential not only for speech, but also for swallowing and respiration. Its tissues are affected by the presence of alcohol and cigarette smoke. In this report we present our findings on the effects of smoking and drinking on histological changes in laryngeal tissue. The larynges studied were those of autopsy patients: cases with damaged tissue were excluded. We studied the larynges of 84 men (non-smoker and non-drinker, 22 cases; smoker and drinker, 62 cases) and 48 women (non-smoker and non-drinker, 40 cases; smoker and drinker, 8 cases) between the ages of 12 and 88. The squamous metaplasia of laryngeal epithelium was examined using the gross staining method (Pyronin Y) of STELL et al. (J. Laryngeal. Otol. 86: 589-594, 1972). The squamous epithelium is unstained, whereas the respiratory epithelium is a brilliant red. The area of metaplasia in the supraglottic region increased with aging, tobacco and alcohol consumption. Microscopic changes of the laryngeal epithelium were investigated using the hematoxylin-eosin staining method. The thickness of epithelium of the supraglottic region and vocal cord increased with age. There is a significant difference in the thickness of the epithelium of the supraglottic region and vocal cords of smoking and drinking patients, when compared with the same tissues of non-smokers and non-drinkers. Furthermore, there is a significant difference in those tissues of the supraglottic region of heavy smokers, when compared with light smokers, but no significant difference when compared with drinkers. However, there is no significant difference in the thickness of vocal cord tissues when comparing light smokers and drinkers on the one hand, and heavy smokers and drinkers on the other.
