The use of bone cement in ossicular chain reconstruction (OCR) represents an area of recent interest. This multi-institutional retrospective study assesses the efficacy of glass ionomer cement (GIC) in OCR following the explantation of a fully implantable active middle ear implant. A postoperative 4-frequency mean air-bone gap (ABG) was obtained for 15 subjects by averaging 0.5, 1, 2, and 4 kHz frequencies. For Group A (short-term, N = 15), at a mean of 4.5 months postoperatively, 9 (60%) achieved an ABG between 0 and 10 dB, 5 (33%) were 11 to 20 dB, and 1 (7%) was 21 to 30 dB. For Group B (long-term, N = 5), at a mean of 50 months postoperatively, 4 (80%) were 0 to 10 dB and 1 (20%) was 11 to 20 dB. These results suggest that GIC represents an effective means of ABG closure after device explantation.
骨水泥在听骨链重建（OCR）中的应用是近期备受关注的领域。这项多机构回顾性研究评估了玻璃离子水门汀（GIC）在完全植入式有源中耳植入物取出后用于听骨链重建的疗效。通过对15名受试者的0.5、1、2和4kHz频率进行平均，获得了术后4频率平均气骨间隙（ABG）。对于A组（短期，N = 15），术后平均4.5个月时，9名（60%）受试者的ABG在0至10dB之间，5名（33%）在11至20dB之间，1名（7%）在21至30dB之间。对于B组（长期，N = 5），术后平均50个月时，4名（80%）受试者的ABG在0至10dB之间，1名（20%）在11至20dB之间。这些结果表明，GIC是装置取出后实现ABG闭合的有效手段。
