[Irreversible vocal changes in pregnancy (author's transl)].

Disturbances of voice during pregnancy are not uncommon. Non-inflammatory changes of the larynx (or laryngopathia gravidarum) occur but disappear spontaneously after parturition. Two cases of permanent deep voices in women due to pregnancy have been described in the literature. A similar case of this rare afflication is described in one of our patients. However, review of these cases indicates that such mutations of voice due to pregnancy represent an independent clinical problem which should be differentiated from true laryngopathia gravidarum.
