Abstract: | The use of inhaled steroids in the treatment of asthma is not without its complications. In some studies up to 50% of such patients complain of oropharyngeal and voice problems. We present the findings in 22 patients complaining of dysphonia who underwent videostrobolaryngoscopy (VSL) and computerized speech analysis. A number of abnormalities were identified. On VSL, these included mucosal changes (noted in 58%), apposition abnormalities (noted in 43%), and supraglottic hyperfunction (noted in 40%). On speech analysis, cycle-to-cycle irregularity was frequently noted (mean of 39%). Maximum phonation time was reduced in 73%. Our findings did not confirm the widely held views that steroid dysphonia is due primarily to a fungal infection or a steroid-induced adductor myasthenia of the larynx. A larger-scale prospective study is indicated. |
