Ear diseases (otology and neurotology) are a specialty of otolaryngology, dealing with the treatment of diseases involving both the ear and the brain at the same time.
All diseases and tumors of the external auditory canal are of interest to otology.
Middle ear infections, cholesteatoma surgery, fluid accumulation in the middle ear, calcification of the middle ear and inner ear connection (otosclerosis) are also of interest in otology.
Inflammatory disorders of the inner ear, such as labyrinthitis, vestibular neurinitis, and dizziness, such as benign paroxysmal positional vertigo, are the major diseases of neurotology.
