Ossicular chain fixation

Ossicular chain fixation refers to the presence of fibrous tissue (chronic adhesive otitis media) which usually appears as noncalcified, soft-tissue density encasing some or all of the ossicular chain.

It may be present in the meso- and epitympanum yet it usually occurs in the niche of oval window forming so called ‘‘peristapedial tent’’.

Clinically the patient complains of conductive hearing loss in the setting of chronic otomastoiditis and dry ear.
