[Results of surgical treatment for advanced otosclerosis].

Abstract

OBJECTIVE:

To assess the effect of stapes surgery on advanced otosclerosis (AO).

METHODS:

In 300 cases randomly collected of otosclerosis in 1970 to 1999, 68 cases (77ears) were selected for retrospective analysis, which met the criteria of advanced otosclerosis (mixed deafness, with bone-conduction levels exceeding 40 dB and air-conduction levels exceeding 70 dB in 500 - 2000 Hz).

RESULTS:

The air-conduction of sixty-eight cases (77 ears) were from 77.32 dB to 53.7 dB (500-2000 Hz) after operation, mean decreased 23.62 dB. Of 71 ears (92.21%) obtained air-conduction improved over 10 dB, of 46 ears (59.74%) gained A-B Gap closure in 10 dB. Air-conduction were from 79.01 dB to 58.23 dB (500 - 4000 Hz) after operation and mean decreased 20.78 dB. Of 68 ears (88.31%) obtained air-conduction improved over 10 dB, of 32 ears (41.56%) gained A-B gap closure in 10 dB. After followed up 5-25 years, of 67 ears were retained stabilization, of 28 ears obtained more improve than postoperation. But 4 ears had drop (all was stapes-elevation and re-improvement after them was reviewed).

CONCLUSION:

Stapes surgery is effective operation to cured otosclerosis, advanced otosclerosis or far-advanced otosclerosis had greater help to improved hearing.
