[Operative therapy of the adhesive otitis media].

OBJECTIVE

To study the operative indications and treatment for adhesive otitis media (AOM).

METHODS

Sixty-nine cases of AOM were undergone tympanoplasty between 1995 to 2000. Preoperative average air-bone gap(A-B gap) were (43.7 +/- 3.9) dB. Forty-one cases could be postoperative followed up for more than one year. Preoperative average A-B gap of this group were (43.8 +/- 4.2) dB. The adhesive ear drum and the other processes in middle ear were inserted and reconstructed with cartilage.

RESULTS

The postoperative average A-B gap after one month(69 cases) and one year(41 cases) were (23.7 +/- 8.6) dB and (27.9 +/- 10.7) dB. In the long-time follow-up group, the A-B gap of 18 cases (43.9%) were less than 20 dB. Twenty-four cases (58.5%) become a nearly normal tympanum.

CONCLUSION

The AOM can treatment with tympanoplasty. But the indication must be carefully selected. The cartilage was a good material for reconstruction of the ear drum to treatment the AOM. The influence factor were analyzed.
