Totally 34% of patients presented with facial nerve weakness and 45% of these cholesteatomas arose from the supralabyrinthine area (32.8%) and from the petrous apex (12.2%).\n\nCONCLUSION:\u00a0In this unified classification system, the otologist sees congenital cholesteatoma as a continuum, with facial nerve involvement and anacusis as part of the picture. This system of congenital cholesteatoma accommodates the supralabyrinthine and petrous bone locations of the disease.\n\nCite this article as: Honnurappa V, Mahajan N, Kumar Vijayendra V, Redleaf M.
