Background: Damage to ethmoid skull base (ESB) and lateral lamella (LL) during endoscopic sinus surgery (ESS) causes penetration into brain.The height of the ESB and the length the LL can vary significantly. The aim of this study was determining the relationship between height of ESB and length of LL by sectionalcoronal computed tomography(CT) scans before ESS. Material and methods:In a cross sectional study, we admitted 100 patients who came to ENT clinic of AL Zahra hospital, then we obtained consent regarding the use of CT scan stereotype. After collecting the CT scan files, each stereotype was evaluated, and by using software in two sides the height of ESB and the length of LL were measured,investigated and recorded. Next, the maximum and minimum height and length in the two sides was measured and its mean calculated. Then, the relationship between the length of LL and the height of ESBwas investigated.Results: There was a direct correlation, with rate of 0.25 between the length of right LL and height of right ESBthatwas significant according to Pearson Test (p=0.013). Also, therate of correlationbetween the left LL and height of left ESB was 0.15that was not significant according to Pearson Test (p=0.15).Conclusion:Based on this study there was a direct correlation between height of the right ESB and the length of LL but this correlation is very low, about 0.25 and even this correlation was lower in the case of left, about 0.15, which both of them are not significant. This may be due to other affecting factors, such as length, slope and angle of fovea ethmoidallis from horizontal line.
