Fifty\u2010three guinea pigs were divided into 3\u00a0groups. The defects were filled with autogenous bone cement (ABC) or autogenous bone dust (ABD) on the left side while the contralateral sides were kept intact as the blank control (BC) group or a defect was induced without obliteration as the operation control (OC) group (groups 1 and 2, n = 25 each). The animals were sacrificed at 2, 4, 8, and 12 weeks postoperatively. Group 3 (n = 3) was the ototoxicity positive control (OPC) group. The critical defects were evaluated for bone repair by histologic observation and computed tomography (CT), and the ototoxicity of the material was assessed by measuring shifts in the hearing threshold and changes in cochlear morphology.
