Characteristic of Anatomical Variations in Paranasal Sinus CT-Scan of Chronic Rhinosinusitis Patients at the ENT Clinic Prof. Dr. I.G.N.G Ngoerah General Hospital Denpasar in 2021

Abstract

Background: Anatomical variations and pathological processes in the nose and paranasal sinuses have been widely studied by experts. Many anatomical variations cause chronic sinusitis by causing obstruction of the osteomeatal complex (OMC) and influencing mucociliary transport patterns. Methods: This is a retrospective study based on radiology data of all rhinosinusitis cases that performed a computed tomography scan of the paranasal sinuses at Prof. Dr. I.G.N.G Ngoerah General Hospital Denpasar for one year (January 2021 to December 2021). The sample of this study was all rhinosinusitis patients undergoing surgery, both male and female, from January 1 to December 31, 2021. Results: Based on the results of the research data, the highest anatomical variation was concha hypertrophy in as many as 26 people (38.2%). Conclusion: The most common anatomic variation is concha hypertrophy. Preoperative CT scan examination is essential because it can be helpful as navigation for sinus surgeons. Early detection of anatomic variations is the key for surgical planning and the prevention of complications.
