Description
Cottle Chisel
Named after septal surgery pioneer Maurice Cottle, the Cottle chisel suits bone work inside the nose. It comes straight or curved, in six blade sizes altogether.
Straight widths
The straight version comes in 4, 7, 9 and 12 mm. This spread runs from delicate to fairly wide. So a surgeon can shave a small spur or remove a wider strip of bone.
Curved widths
The curved version comes in 4 mm and 6 mm. A curve helps the edge follow the shape of the septum or nasal floor. It also lets the surgeon approach from an angle when a straight blade would not fit.
Where surgeons use it
During septoplasty, a chisel can free bony parts of a deviated septum. For instance, the surgeon may separate a spur from the maxillary crest. Then forceps remove the freed bone.
Choosing among six options
Firstly, pick straight or curved based on the steps you do most. Next, choose widths that fill gaps in your tray. Many teams keep a narrow and a medium straight blade plus one curved blade.
Caring for your Cottle chisel
Wash off blood and bone promptly, especially along the edge. Then clean by hand and dry thoroughly. Also store the chisel so its edge touches nothing else.
