Surgery of the frontal recess and frontal sinus.

Surgery on the frontal recess and frontal sinus remains a challenge for endoscopic sinus surgeons. This paper examines the philosophy behind such surgery and presents a technqiue for 3-dimensional reconstruction of the anatomy of the frontal recess and frontal sinus. Utilizing this anatomical reconstruction the surgeon is encouraged to develop a pre-operative step-by-step surgical plan for each cell identified within the frontal recess and frontal sinus and thereby predict the anatomy of this region before surgery is undertaken. An increased understanding of the anatomy of this region should improve the surgeon's surgical confidence and ability to remove all the obstructing cells from the frontal sinus ostium.
