Pre-operative Computed Tomography Findings and Pre-operative Findings in Sinonasal Diseases - A Comparative Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 8
Abstract
Background: Computed tomography (CT) scan is a useful diagnostic tool in the evaluation of diseases of the paranasal sinuses (PNS) and an integral part of surgical planning. Mastering of anatomy of PNS and its variations helps in understanding the pathological changes and radiological signs of sinonasal diseases to guide an ear, nose, and throat in planning the surgery. Aim of the Study: To compare the CT scans findings and intraoperative findings following functional endoscopic sinus surgeries (FESS) for sinonasal diseases. Material and Methods: A total of 58 patients with sinonasal diseases were included in the study. Pre-operative CT scans were taken in all the patients, and their intra-operative FESS findings were noted. Both the findings were compared and correlated for any discrepancy in reading the radiological signs. The specificity and sensitivity of the CT scan findings were analyzed. Observations and Results: A total of 58 patients were aged between 14 years and 63 years with a mean age of 39.50 ± 3.70. 32 patients belonged to the age groups of 24–43 (55.17%). The most common symptom in the study observed was nasal obstruction in 43 (74.13%) followed by nasal discharge in 38 (65.51%). The positive predictive value was the highest for mucosal thickening was 100% followed by a pathological variation in ethmoid sinus (92%). Conclusions: Specificity of the CT scan findings pertaining to mucosal thickening, fungus, polyp and pathologic variations in ethmoid sinus was good (>80%). CT with its excellent capability for displaying bone and soft tissues is the current diagnostic modality of choice for evaluating the osteomeatal complex. Sensitivity was good for pathological variations in maxillary antrum and ethmoid sinuses (>90%).
