The usage of external drainage in the treatment of chronic exudative otitis media raised as much hope as it did doubts. However this method was not put to common use immediately. The doubts observed by laryngological mele delayed the usage of this method of treatment in many cases. In the Otolaryngological Clinic of the Surgery Institute in Warsaw, the external drainage in chronic exudative otitis media has been in use for several years. The authors of this paper present their own distant observations upon treated patients. They evaluate the efficiency of hearing examination and the lack of recurrence of inflammation of the middle ear.
