A labyrinthine fistula ranges from 5.8% to 21%. The involvement of inner ear is a negative prognostic factor in term of hearing preservation. We report three cases with intralabyrinthine extension of cholesteatoma and high risk of hearing loss during surgery, but the hearing was maintained as serviceable in all cases. All different hypothesis were discussed: gradual aseptic inflammatory process involving the labyrinth, creating a “wall” between superior labyrinth and the cochlea; a slow and progressive disease could lead to inflammation and produces a sealing effect, protecting hearing function from vestibular damage; a sudden decompression of the endolymphatic system could cause the collapse of the utricle and therefore a passive closure of the utriculo-endolymphatic valve, preventing the leakage of endolymph from saccule and cochlear duct.
