摘　　要：目的 评估听骨成形术的临床疗效。方法 用自体残存听小骨雕刻成形重建听骨连接。结果 术后３个月，１７１／１９６耳听力提高＞１５ ｄＢ，总有效率为８７．２４％；１４３／１９６耳达到应用听力水平；骨－气导间距＜２０ ｄＢ为６８％，１年后为６４％，随访３～５年仍保持术后的听力水平。结论 采用自体残存听小骨行听骨成形术是治疗慢性化脓性中耳炎、先天性中耳畸形及外伤性听骨链中断的一种有效方法。Objective To evaluate the effect of ossiculoplasty in patients who have sustained fixation, dislocation, or dissolution of the ossicular chain as a result of trauma infection or congenital deformity. Methods The shaped columella was sculptured in the remnants of the incus and malleus. The shape of minor columella was similar to a cup. A small acetabulum was bored out to fit the capitulum of the stapes and a notch was made to hold the manubrium of the malleus. The long process was served as manubrium if the malleus is defective. The placements remade were created by using the malleus and incus and to rest between the footplate and tympanic membrane. Results The total effective rate of hearing gain (>15 dB) was 87.24% (171/196) and 143 out of 196 had regained socially acceptable hearing ability. The residual air-bone gap was <20 dB in 68% of all cases 3 months after surgery, and in 64% after 1 year. Then they remained stable over time, even in patients 3- 5 years after the operation. Conclusion This type of ossiculoplasty is an adequate procedure for primary restoration of hearing in chronic otitis media, congenital malformation of the middle ear and ossicular chain dislocation.
