Title: Microanatomic Study of the Temporal Bone of Guinea Pig
Abstract: Objective To locate exactly the structures of middle and inner ears. Methods The location of the middle and inner ear was investigated and photographed with 0.6~1 times magnification under the zeiss dissection microscope in 15 healthy adult guinea pigs. Results The located structures of the middle ear in the guinea pig include tympanic membrane, ossicular chain, oval window, round window, tympanic foramen of eustachian tube, facial nerve, etc; and the inner ear structures include cochlear, triple semicircular canals, utricle, sacculus, sigmoid sinus, internal auditory meatus, endolymphatic sac, foramen of vestibular aqueduct, foramen of cochlear aqueduct, etc. Conclusion Compared with human temporal anatomy, there are some exceptions in spite of general similarities. This study will be a helpful guide for ear researchers to exactly locate the structures of middle or/and inner ear in guinea pigs.
