Abstract

Background: The diagnosis of chronc rhinosinusitis relies on clinical judgment based on a number of subjective symptoms and few findings in physical examination in addition to Computerized Tomography and endoscopy.

Objective: Correlation of findings and preoperative diagnoses detected by nasal endoscopy and computed tomography scan of the nose and paranasal sinuses in patients with chronic rhinosinusitis with or without polyps with operative findings and intraoperative diagnoses to declare the most accurate tool for diagnosis.

Material and methods: Forty patients with chronic rhinosinusitis. The diagnosis was confirmed by symptoms, nasal endoscopy and CT of the nose and paranasal sinuses. Then patients were subjected to the endoscopic sinus surgery, final diagnosis was confirmed based upon endoscopic surgery.
Data from the nasal endoscope and CT were reported, statically analyzed, and compared to the data obtained from the surgery.

Results: Twenty six patients had a match between the sinuses on the CT and during the FESS, (65%), while 14 patients had a mismatch between their sinuses on the CT and FESS (35%). Out of the 14 patients, 12 had a mismatch in one sinus and 2 had a mismatch in more than one, with the maxillary, anterior ethmoid and the frontal sinuses showing the most degree of mismatch in 4 patients.
The degree of matching between the endoscope/CT to the intraoperative endoscopic findings were 40 % with the endoscope and 50% matching with the CT.

Conclusion: No single procedure can be sufficient in accurately diagnosing chronic rhinosinusitis, and its different classes. Both procedures are required to be performed pre-operatively as they are complementary to each other, for adequate guidance and identification of the important anatomical landmarks of the nose and paranasal sinuses through the endoscopic sinus surgery.
