This study aimed to compare the hearing results of incus interposition and bone cement ossiculoplasty in patients with incus long process defects.
Ninety-nine patients with incus long process defects were included. Incus interposition was performed in 49 patients (group 1) and bone cement ossiculoplasty was performed in 50 patients (group 2). Group 1 included 29 female and 20 male patients, with a mean age ± standard deviation of 29.43 ± 12.5 years (range, 8–58 years). Group 2 comprised 32 female and 18 male patients, with a mean age ± standard deviation of 29.1 ± 14.89 years (range, 8–67 years).
The mean hearing gain ± standard deviation was 15.2 ± 9.01 dB in group 1 and 19.36 ± 9.08 dB in group 2. Hearing gain was significantly greater in the bone cement group than in the incus interposition group (p = 0.0186). Successful hearing results (i.e. air–bone gap < 20 dB) were achieved by 63.2 per cent of group 1 patients and 78 per cent of group 2 patients.
Incus interposition and bone cement ossiculoplasty are safe and reliable methods with which to manage incus long process defects. Bone cement ossiculoplasty gives a greater hearing gain in appropriate cases.
本研究旨在比较砧骨长突缺损患者行砧骨植入术和骨水泥听骨链成形术的听力结果。
纳入99例砧骨长突缺损患者。49例患者（第1组）行砧骨植入术，50例患者（第2组）行骨水泥听骨链成形术。第1组包括29例女性和20例男性患者，平均年龄±标准差为29.43±12.5岁（范围8 - 58岁）。第2组包括32例女性和18例男性患者，平均年龄±标准差为29.1±14.89岁（范围8 - 67岁）。
第1组平均听力增益±标准差为15.2±9.01dB，第2组为19.36±9.08dB。骨水泥组的听力增益显著大于砧骨植入组（p = 0.0186）。第1组63.2%的患者和第2组78%的患者获得了成功的听力结果（即气骨导间距<20dB）。
砧骨植入术和骨水泥听骨链成形术是治疗砧骨长突缺损安全可靠的方法。在适当的病例中，骨水泥听骨链成形术能带来更大的听力增益。
