The objective of this study was to assess the role of computed tomography (CT) scan preoperatively in detecting nasal and paranasal pathologies which impact the surgical outcome, and operative plan.Methodology: This was retrospective descriptive study of 81 patients who underwent preoperative CT scan and were referred for functional septorhinoplasty, at King Abdullah Medical City from 2012 to 2018.Results: There were 75 (92.59%) patients with internal nasal valve obstruction, 26 (34.67%) had bilateral internal nasal valve obstruction, followed by 25 (33.33%) had left internal nasal valve obstruction, and 24 (32%) with right internal valve obstruction. Two third of the cases 68 (83.95%) had severely crocked nose with septal deviation, 21 (30.88%) had J shape, 19 (27.94%) had inverted J shape, 12 (17.64%) had inverted C shape, 10 (14.70%) had C shape, 1 (1.47%) had S shape, and only 5 (7.35%) cases had a normal septum. Of the 81 patients, 68 (83.95%) had grade five septal deviation, six (7.41%) had hidden pathology detected, five (6.17%) had medico-legal cases (trauma and septal perforation), and two (2.47%) had congenital anomaly.Conclusion: Preoperative CT for septorhinoplasty is beneficial to detect anatomy of nose and paranasal sinuses, which is better than nasal endoscopy. Although, cost and radiation burden should be considered, especially in regards to the risk of development of future malignancy. CT scan prior to septorhinoplasty might be a proper tool to decrease surgical failure. PB - https://www.ijmdc.com DO - 10.24911/IJMDC.51-1570357791 UR - https://www.ijmdc.com/?mno=68520 ER -
