A detailed subgross morphometric study on the auditory ossicles of the New Zealand rabbit.

This study was designed to reveal, in detail, the features of the auditory ossicles of the New Zealand rabbit, one of the most frequently used animals in scientific researches. Heads of 10 dead adult New Zealand rabbits of both sexes weighing 2.5 +/- 0.2 kg were used in the study. The auditory ossicles were gently removed from their situs and observed. The auditory ossicles were three small bones: the malleus, the incus and the stapes. The lenticular bone seemed to be the lenticular process, as is in human beings. In general, macroanatomic features of the bones were similar to those reported in the literature. Findings in this study, however, differed greatly, especially in detail. There were statistically significant differences in the morphometric data of the features of the auditory ossicles between the right- and left-hand sides. Data from the right-hand side were significantly higher.
