[Functional laryngectomy using a technic of subperichondrial laryngeal curettage].

A new technique of functional laryngectomy using sub-perichondral curettage of some or all of the soft parts of the larynx is described. This method has an embryological and anatomical basis. It is supported by a score of cases which have had a satisfactory outcome, all the patients operated on having been decannulated. Histopathological research was continued with a view to confirming the function of the perichondrium and the cartilage as a barrier to neoplastic invasion.
