Otolaryngologic heuristics: a rhinologic perspective.

Rhinological heuristics are adapted from common principles within the field of otolaryngology. The most important principle in achieving quality endoscopic sinus surgery is good haemostatic control of the surgical field. Once this is achieved, the surgeon can then begin advancing to other heuristic principles. Thinking one to two moves in advance allows the surgeon to take advantage of the many dually purposed instruments available. Learning to visualize buried structures by their subtle projections quickly follows. Finally, an ergonomically positioned surgeon with intricate anatomical knowledge of the sinonasal cavities permits a second surgeon to assist and greatly expand the limit of what is possible.
