In the majority the relapse occurred generally within six months after the treatment, but in some it occurred after more than six months to one and a half years afterward. 3) As for the findings concerning the conditons of the auditory tube in the examinations either by nasopharyngoscopy or of the patency of the Eustachian tube, all showed a marked improvement. 4) Concerning the hearing recovery at the time of re-examinations conducted during the periods from two to six years after the treatment, severe cases showed a morn marked improvement rather than the mild cases. Of them the majority revealed the average hearing loss of about 10 db in speech range.
