Three-dimensional building block approach to understanding the anatomy of the frontal recess and frontal sinus

Frontal sinus and frontal recess surgery remain a challenge for endoscopic sinus surgeons. In order to remove obstructing cells from the frontal recess and frontal sinus, the surgeon needs to have a clear understanding of the anatomy of this region. The technique presented uses high-definition computerized tomography scans to create a 3-dimensional picture of the cellular structure of this region, which allows surgeons to formulate a step-wise surgical plan prior to surgery and encourages cell-by-cell removal of the obstructing cells during surgery. This improved understanding of the anatomy of this complex region should allow the surgeon to perform a competent and complete dissection with improved results.
