Microdissection of Miniature Pig Ear

ObjectiveTo investigate the suitability of miniature pigs as an animal model for otological research.MethodsMicrodissection of the temporal bone was performed on 10 miniature pigs and recorded on photographs.ResultsThe morphology and measurement of the external, middle and inner ear and the lateral recess of the miniature pigs were obtained by microdissection.ConclusionCompared to traditional animal models, the miniature pig may be a better model for biomedical research because of its many similarities in physiological functions with humans. Similarities of the temporal bone structures, including the external, middle and inner ear and the lateral recess, between the miniature pig and human make the animal a potentially useful model for otological research.
