ABSTRACT
BACKGROUD AND OBJECTIVES:
Incus erosion with intact stapes head was most common ossicular impairment in chronic otitis media. Here, we aimed to investigate hearing and clinical results of the ossiculoplasties when the stapes head was intact. SUBJECTS ANDMETHOD:
We analyzed 281 patients of ossiculoplasties over stapes head performed from 1990 to 2005. Patients were divided into 3 groups Si group (n=121) included patients with interposition of prosthesis between malleus and stapes; Sc-PORP group (n=99) included patients with columellarization between tympanic membrane and stapes head with PORP; Sc-SC group (n=61) included patients with columellarization with the autologous materials between tympanic membrane and stapes head. Hearing improvement and extrusion rates of three groups were analyzed.RESULTS:
At 6 months after the surgery, the postoperative air-bone gap (ABG) level within 20 dB was 45%, 44%, 25% in Si, Sc-PORP, Sc-Sc, respectively. The closure of ABG was statistically better in Si and Sc-PORP compared with Sc-SC. In canal wall-up mastoidectomy, Sc-PORP showed better hearing results than Si, while Si was better than Sc-PORP in canal wall-down mastoidectomy. At 36 months after the surgery, extrusion-free survival according to the type of ossiculoplasty were 100%, 89.6%, 100% in Si, Sc-PORP, Sc-SC, respectively.CONCLUSION:
Si and Sc-PORP provide good hearing results. However, Si has lower extrusion rates than Sc-PORP and remains stable over time.
