The pаtient is а 58-yeаr-оld female with a cоmplaint оf hearing loss in her right ear. The difficulty was first noticed about five years earlier and has been gradually progressive to the point where she relies entirely on her left ear for communication. She does not experience true vertigo, but frequently she has attacks of unsteadiness and occasional headaches. She also complains of a constant noise in her right ear, which she describes as "bacon frying."

Her main communication problem is in groups or noisy backgrounds, which she attempts to avoid. Likely pathology is __________________?
