[Study on clinic and etiology of human laryngoceles by help of Silopren -casts (author's transl)].

In different papers the statistical number of the finding of a laryngocele is changing. This perhaps should be related to the fact that there is no equal definition. Therefore an own definition for the examination of 50 Silopren -casts from laryngeal autopsies is given. In 64% of the cases one or more sacculi laryngis were found. The sex-distribution was about 50%. By looking at the clinical history it seems that exogenic factors have an influence on the extent of laryngoceles.
