Abstract
Objective:To investigate the bone conduction (BC) in tympanosclerosis patients and its changes after surgery for tympanosclerosis, as well as its possible causes.Method:Retrospectively analyzed 30 cases of tympanosclerosis patients.Result:Before surgery, the average BC of the operated ear was (21.06±8.88) dBHL, the average BC of the healthy side was (16.78±8.97) dBHL, the difference had a statistical significance (t= 3.072, P< 0.01). The BC threshold, air conduction (AC) and ABG were significantly lower after operation. Preoperative BC at 2 000 Hz was the highest threshold (25.17±10.95) dBHL, and the postoperative decrease of BC thresholds at 500 Hz, 1 000 Hz and 2 000 Hz were statistically significant (P< 0.05 or P< 0.01). Tympanoplasty with mastoidectomy for BC threshold improvement was better than only tympanoplasty (P< 0.05)Conclusion:Tympanosclerosis leads to elevated BC threshold. Removal of tympanosclerosis lesions together with the removal of the lesions in antrum and mastoid and the reconstruction of sound conduction structures not only improve AC hearing and shorten ABG, but also improve postoperative BC hearing significantly.
