Recent results of tympano plasty and its unsettled problems

, : Recent results of tympano plasty and its unsettled problems. Otologia Fukuoka 28(SUPPL 1): 281-285

The results of tympanoplasty of 620 cases [human] operated on from 1964 to 1974 (series K) and of 229 cases operated on from 1977 to 1980 (series M) were studied. The cases in which the postoperative airborne gap is < 30 dB are judged to be successful. In simple otitis media, the success rate for hearing and otorrhea was 91% in the series M and 75% in the series K. As the success rate in the series K was > 90% after 1970, it was reasonable to assume that modern tympanoplasty was successful. One of the unsettled problems is the discouraging result for adhesive otitis media. The success rate in series K was 41% and that in series M was 44%. No progress in the results of tympanoplasty for this disease was evident from 1964 to 1980. Modern tympanoplasty seems unavailable for this condition. The other problem is the poor results in type IV tympanoplasty for all types of middle ear diseases. The success rate in both series is 27% and 24%, respectively. To resolve this difficulty the use of TORP, PORP or homograft should be attempted.
