  • Title: Canal wall window mastoidectomy for extensive labyrinthine cholesteatoma: total dissection and hearing preservation.
    Author: Bergeron M, Saliba I.
    Journal: Int J Pediatr Otorhinolaryngol; 2011 Jul; 75(7):976-9. PubMed ID: 21605917.
    Abstract:
    This case report highlights outcomes of a 6-year-old patient who preserved functional hearing after complete dissection of an extensive labyrinthine cholesteatoma causing two semicircular canals fistulas with endolymph leak, tympanic and labyrinthine fallopian canal erosion of the facial nerve and internal auditory canal invasion with cerebrospinal fluid leak. The patient preserved 40 dB average of bone conduction threshold and 92% of speech discrimination score at 26 months postoperatively. This article reveals that canal wall window mastoidectomy might be an option even in cases of extensive cholesteatomatous labyrinthine fistula therefore avoiding hearing loss and long life cleaning of a canal wall down mastoid cavity.
