ABSTRACT
OBJECTIVE@#To study the effects of different types of prosthesis used in ossiculoplasty on mastoidectomy of treating chronic otitis media.@*METHOD@#One hundred and forty three patients with chronic otitis media were treated by canal wall-down tympanoplasty with ossiculoplasty in a single stage. According to material of prosthesis, they were classified as titanium group (group A, 52 cases), hydroxypatite group (group B, 47 cases) and autogenous bone group(group C, 44 cases). The postoperative complication and hearing thresholds were analyzed in the 24 months follow-up. Average postoperative air-conduction gain and air-bone gap were measured at four frequencies: 0.5, 1.0.2, and 4.0 kHz.@*RESULT@#12-month after operation, the average air threshold and air-bone gaps of the three groups were reduced (P < 0.05). The reconstruction successful rate (78.7%) of group A was slightly better than that of B, C (68.1%, 70.4%), there was no statistically significant difference. The difference of the average air threshold and air-bone gaps of group B, C after 24-month of operation and 12-month after operation was statistically significant (P < 0.05). The reconstruction successful rate (48.9%, 45.5%) of group B, C was lower than that of A (76.9%), the difference was also statistically significant (P < 0.05).@*CONCLUSION@#Prostheses using titanium type could give good functional results and strong stability with low complication.
