Prevention of blood staining of endoscope tip during Functional Endoscopic Sinus Surgery: sleeve technique.

Optimisation of the endoscopic view during FESS may require correction of a deviated septum. The resulting incision leads to bleeding which could obscure the view of the endoscope. Repeated cleaning of the endoscope intraoperatively is time consuming and traumatisation of the lining of the nasal mucosa may lead to formation of adhesions post operatively. We discuss the use a segment of suction tubing that can act as a conduit or sleeve for the passage of the endoscope into the nasal cavity. This protects the endoscope tip from the bleeding area.
