The inner ear can be examined mainly by imaging, MRI and CT, and otoacoustic emission and cochleography.
The ear is the hearing organ of the human body and is divided into the outer ear, middle ear and inner ear, and different parts of the ear are examined in different ways. The outer ear can be visualized with an otoscope to observe the condition of the external auditory canal and the eardrum.
In the inner ear, CT of the temporal bone and MRI of the inner auditory canal are usually performed to clarify whether the structure of the inner ear is abnormal or not, whether there is destruction of the semicircular canals, semicircular canal fissure, enlargement of the vestibular aqueduct and other structural abnormalities; whether it is occupied or not, such as acoustic neuroma, etc.; rolling contrast can also clarify the cochlear effusion situation.
Hearing problems can do otoacoustic emission, and cochlea electrogram examination, clear inner ear cochlear hair cells, determine the cause of hearing loss, to help identify the auditory nerve and its peripheral conduction pathway of various types of deafness, and objectively assess the effect of treatment.
