Sacculus laryngis.

100 preparations of the larynx from 104 autopsies were examined with reference to the condition of the laryngeal saccule. In 54% of the cases the saccule could not be demonstrated. The examination showed a clear sex difference regarding the existence and size of the laryngeal saccule. In 6% the laryngeal saccules were pathologically enlarged as interne laryngoceles, in all cases in males. The laryngeal saccule must regarded as an atavistic structure.
