Abstract:

To find out the frequency of protrusion of the Internal Carotid artery in the sphenoid sinus and dehiscence of the carotid canal in a subset of the Karachi population. Study design: This was a cross-sectional study conducted at the Radiology Department of Ziauddin University. Methodology: We analyzed 270 head and neck CT scans 270 Head and neck CT scans (540 sides) were analyzed. CT was performed on a 16-slice Toshiba Alexion at Ziauddin Hospital, Karachi. SPSS version 20 was used for data analysis. Results: Out of 270 CT scans analyzed, 28 (10.3) scans showed protrusion of ICA in the sphenoid sinus. Out of 45 (16.6) of the subjects showed dehiscence of the carotid canal. Out of total dehiscence, present unilateral cases were more frequent as compared to bilateral. The unilateral protrusion was also more common as compared to the bilateral protrusion of the ICA. Conclusion: Knowledge of dehiscence and protrusion related to ICA and sphenoid sinus anatomy is essential to avoid complications in endoscopic sinus surgery
