Killian's Bayonet shaped gouge
The Killian's nasal gouge is bayonet shaped. Its shaft is bent in such a way that the
tip lies on a higher plane than the handle. This ensures that the hand holding the
instrument does not block the vision of the operating surgeon. The surgeon can
constantly visualize the tip of the instrument inside the nasal cavity.
The tip of the instrument is U shaped and is very sharp. This helps in removal of
spurs and sharp projections during septal surgeries. Its broad handle can be
hit conveniently using a mallet.
The instrument is held in place and its handle is tapped gently using a mallet. The
tip of the gouge cuts through the bony projection which can be removed easily with
a Tilley's forceps.
