Abstract

Purposes: To evaluate the sphenoid sinus pneumatization on sinus multi-slice CT scanner (MSCT) in the pre-endoscopic sinus surgery of chronic sinusitis patients. Matherial and Method: The cross sectional descriptive study on the chronic sinusitis patients who underwent the sinus MSCT and the endoscopic sinus surgery. Then, the sphenoid sinus was classified after the classification of Hammer. The sphenoid sinus pneumatization was evaluated and classified on sagittal plan to avoid the surgery complication. Results: From 09/2020 to 9/2022, 200 chronic sinusitis patients who underwent the sinus MSCT and endoscopic sinus surgery at Hanoi Medical University Hospital. Among them, 78 patients with sphenoid sinus pneumatization was observed, account for 39% of all study population. The sphenoid sinus was pneumatized into the base of skull on 40 patients, account for 51.28%, into the anterior clinoid process on 29 patients, account for 31.28%. The internal carotid bulging into the sphenoid sinus was observed on 4 patients, account for 5.13% and the sphenoid sinus pneumatization caused an anormal septal on 5 patients, account for 6.41%. Conclusion: The sphenoid sinus pneumatization was a common anomaly. The detection and classification of this anomaly on MSCT had an important role for the pre-endoscopic sinus surgery evaluation.
