otosclerosis
Otosclerosis is a condition of the middle and inner ear where portions of the dense enchondral layer of the bony labyrinth]] remodel into one or more lesions of irregularly-laid spongy bone. As the lesions reach the stapes the bone is resorbed, then hardened (sclerotized), which limits its movement and results in hearing loss, tinnitus, vertigo or a combination of these. The term otosclerosis is something of a misnomer: much of the clinical course is characterized by lucent rather than sclerotic bony changes, so the disease is also known as otospongiosis.

==Etymology== The word otosclerosis derives from Greek ὠτός (ōtos), genitive of οὖς (oûs) "ear" + σκλήρωσις (sklērōsis), "hardening".
