From September 1989 to December 1992, 49 patients had been observed at the Centre Hospitalier de Soavinandriana and 31 cases at the prison infirmary of Antananarivo from April 1990 to December 1992. The 31 laryngeal tuberculosis observed in prison existed among 9.1% of tubercular patients, were associated to 10.9% of pulmonary tuberculosis and represented 24.2% of extrapulmonary tuberculosis. The 49 laryngeal tuberculosis of the CENHOSOA were present among 4.6% of tubercular patients, were associated to 7.9% of pulmonary tuberculosis and represented 8.4% of all the extrapulmonary tubercular localizations. Voice disorders, even if always present, rarely represented (<30%) a reason for tuberculosis discovery. Comparison with the whole of tuberculosis cases showed that laryngitis was not most frequent in retreatments and that there was no statistically significant difference in death risk. Laryngeal tuberculosis being mostly in the shadow of pulmonary tuberculosis, it develops in the same way under the same treatment, except when a very ancient laryngitis has given rise to irreversible fiber lesions. Recall of this very early known localization is made in a didactic perspective: in a developing country, all chronical voice disorders must induce to research of tuberculosis.
