Specialized surgical burrs ( 122, 124, 162, 164 ) permit safely fenestrating the otic capsule bone adjacent to the scala tympani ( 44 ) of the cochlea ( 34 ) without damaging the basilar membrane ( 52 ) or organ of cordi. The invention disclosed herein may also be adopted for safely fenestrating other areas of the inner ear such as the scala vestibuli ( 42 ), bony labyrinth of semicircular canals, or walls of the vestibule, or perhaps even the oval or round windows thereof.
