In 5 years from May 1993 to Apr 1998 we performed canal wall down tympanoplasty with canal reconstructionmethod using auricular cartilage on 102 ears with fresh cholesteatoma and 58 cases of them wereattic cholesteatoma. An original approach by using the auricular cartilage to prevent retraction pocket wascarried out at the attic reconstraction.
In 58 cases, 33 cases were carried out by single-stage surgery and remain 18 cases were carried out bystaged surgery.
We examined 58 ears with attic cholesteatoma about postoperative results and aeration in the attic andmiddle ear cavity by CT.
After we followed them over 2 years, we could evaluated 43 cases out of 58 about postoperative aerationby CT. Respectively good aeration was seen in 40 cases out of 43 (93%) in the middle ear cavity and in 23cases out of 43 (53%) in the attic.
Respectively the rate of success of hearing was 100% in Tympanoplasty type 1, 73% in type 3-C, 50% inthe case of first-stage surgery→type 3-C, 50% in the case of first-stage surgery→type 4-C. As a whole thesuccess of hearing was 71% in attic cholesteatoma totally.
There was no evidence of perforation in ear drum in all cases and residual cholesteatoma, but in only onecase showed recurrence.
We think that our method is more useful to reconstruct the attic and middle ear with good aeration andto prevent postoperative retraction pocket and recurrence.
