About the Cottle Osteotome
The Cottle osteotome is a slender nasal osteotome with depth graduations marked on the instrument, which let the surgeon read how far the blade has advanced. Manufacturers describe it as a graduated fine osteotome and list it among the standard patterns for nasal bone work.
It belongs to the plastic surgery osteotome group: chisel-like instruments that are tapped with a mallet to cut or shape small bones and cartilage. Versions with a flat handle carrying the graduations are common, and both straight and curved blades are listed.
The Cottle name is attached to several different nasal instruments (elevators, chisels, scissors and specula), so the full description should be checked when ordering.
