Abstract
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.
