The ossicles of the middle ear are affected by the erosive effect of pathology in chronic otitis media. Ossicular reparation can be done via autologous incus or with alloplastic materials. Glass ionomer cement (GIC) is simple to use and saves considerable operative time and expenses especially in developing countries where costly ossicular prosthesis are not affordable for the majority of the patients.
Twenty-five chronic otitis media patients who underwent surgery were included in this study. The reconstruction material used in this study was glass ionomer cement. All patients had erosion of the long process of incus and a normal stapes.
Pure tone average in pre-operative and post-operative period of study patients were 50.09 & 29.92 dB respectively (P=0.01) and the air-bone gap was 24.85 dB preoperatively and 14.05 dB postoperatively. The closure of the air-bone gap was statistically significant (P= 0.01).
The study showed that the use of GIC ossiculoplasty is an efficient method for the reparation of the long process of the incus. The results are encouraging and indicate that it is worthwhile to conduct more trials using this method.
慢性中耳炎的病理侵蚀作用会影响中耳听小骨。听骨修复可通过自体砧骨或使用异体材料来完成。玻璃离子水门汀（GIC）使用简便，可节省大量手术时间和费用，尤其在发展中国家，大多数患者负担不起昂贵的听骨假体。
本研究纳入了25例接受手术的慢性中耳炎患者。本研究使用的重建材料为玻璃离子水门汀。所有患者均有砧骨长突侵蚀且镫骨正常。
研究患者术前和术后的纯音平均值分别为50.09 dB和29.92 dB（P = 0.01），气骨导差术前为24.85 dB，术后为14.05 dB。气骨导差的缩小具有统计学意义（P = 0.01）。
该研究表明，使用玻璃离子水门汀进行听骨成形术是修复砧骨长突的有效方法。结果令人鼓舞，表明使用该方法进行更多试验是值得的。
