Penetration of the cochlear endost by the fibrous component of the otosclerotic focus.
The role of the "third", "fibrous" component of the otosclerotic focus in penetrating and absorbing the cochlear endost is documented. An otosclerotic focus rich in fibrous-granulomatous component shows equal power as spongiotic or sclerotic components producing fragmentation resulting in rosary-formed absorption of the endost opening access to the soft-tissue containing regions of the cochlea.
