Adenoma of the middle ear is a benign tumor that develops from the epithelium of glandular organs and is a rounded node, clearly delimited from the surrounding tissue. A distinction is made between simple adenomas, in which the proliferation of glandular epithelium predominates, and fibroadenomas, in the parenchyma of which the proliferation of stroma predominates.
Middle ear adenoma is a very rare disease in otolaryngology; the tumor develops from the glands of the mucous membrane of the tympanic cavity.
[ Symptoms of middle ear adenoma
As it grows, a middle ear adenoma has the same symptoms as osteoma: constant noise in the ear, hearing loss, and in some cases vestibular disorders. Hearing disorders are caused by the tumor's pressure on the eardrum from the inside, pressure on the auditory ossicles, which also leads to vestibular disorders caused by the stapes pressing into the vestibule of the ear labyrinth and its impact on the cochlear window.

Diagnosis of middle ear adenoma
Diagnosis of middle ear adenoma is based on the use of tympanometry and impedancemetry, which establish a violation of sound conduction. During tympanotomy, a tumor is detected that dislocates the chain of auditory ossicles and is tightly adjacent to the eardrum.
