otospongiosis การใช้

This indicates otospongiosis ( active otosclerosis ).
In otospongiosis, a leading cause of adult-onset hearing loss, the otic capsule is exclusively affected.
Much of the clinical course is characterised by lucent rather than sclerotic bony changes, hence it is also known as otospongiosis.
With otospongiosis, the normally dense enchondral bone is replaced by haversian bone, a spongy and vascular matrix that results in sensorineural hearing loss due to compromise of the conductive capacity of the inner ear ossicles.
