[Launois-Bensaude disease and sleep apnea syndromes. Apropos of a recent case].

About a recent case of Launois-Bensaude's disease (Madelung's disease) the authors discuss the possibility of complications such as bronchopathy and sleep apnoea syndrome. General anaesthetics have to be performed with care, the anaesthetic risk exists even so during the premedication. Such patients have to be explored before the general anaesthetics by sleep polysomnography.
