Abstract
Endonasal sinus surgery (ESS) is a common surgical procedure that is used to relieve chronic, problematic conditions associated with the paranasal sinuses of the cranium. A potential complication that can arise during ESS is damage to the bone surrounding the sinus. Previous research has shown that x-rays can be used to determine areas of the sinus wall to avoid during ESS (Sprinzl et al., 1999). A more accurate means of determining least-dense bone is to use CT, which images the body based on tissue density. Presented here are the results of an examination of 36 cranial CT scans provided by Saint Mary's Healthcare System, depicting all age groups and both sexes. Using analytical software (Amira 3.5), the bone density surrounding the maxillary and frontal sinuses were examined and the least-dense portion of bone was determined using Hounsfield Units (HU's). By determining the bone density by an absolute measure, the area of bone to avoid during ESS can be delineated with accuracy.
