On the basis of the records compiled from January 1961 to May 1971 at Department of Otolaryngology, Kurume University, statistical observations of the results of tympanoplasty in relation to various preoperative and surgical parameters were made with 456 cases of chronic otitis media.
Postoperative perforation of the new drum was found more frequently for free skin graft than for fascia graft. Open cavity techniques were associated with more frequent postoperative perforation than techniques in which the external meatus had been preserved. In the cases of Wullstein's type I and II, less perforations were developed postoperatively for preoperative dry ears than ears with discharge.
In terms of hearing acuity, the results for type I and II were relatively satisfactory whereas they were poor for type BI and IV. The technique with preservation of the external meatus and with fascia resulted in greater rate of success related to hearing than the other techniques.
Follow-up studies were made in 143 cases. Their results also indicated that preservation of the meatus and usage of fascia should be the basic technique for tympanoplasty except for unusual cases. Indication for mastoidectomy was discussed on the basis of X-ray findings and postoperative results.
