The author reported 27 cases of the chronic progressive unilateral labyrinthine deafness who were observed by the author in the period of past 9 years, and the several problems about this disease were discussed.The summary and conclusions are as follows;1) In nearly all cases the deafness occured and developed in childhood or in the young adult stage. (26 in 27 cases, the deafness occured in the years below 20).2) Only a few reports in literature about this disease were found. They were reviewed and discussed.3) As the probable causes of this disease, the following three conditions were described in literature. That is, (1) subclinical mumps, (2) subclinical otitis and (3) hereditary defect.4) From the many findings in the cases observed by the author and remarks found in the literature, subclinical mumps and subclinical otitis do not fully warrant consideration as the cause of this disease. The author believes that the hereditary defect is the most reliable cause of this disease.5) But since there are still more unsolved problems remaining in the field of these diseases, it is hoped that further studies will be reported.
