Variations in paranasal sinuses anatomy are common and vary among populations. Having clear picture of paranasal sinuses anatomy of a chronic rhinosinusitis patients is essential in surgical planning. This study was done to know paranasal sinuses anatomical variations of chronic rhinosinusitis in Javanese patients by Ct-scan. Retrospective chart survey from medical record of the ORL-HNS outpatient unit at Dr. Soetomo hospital Surabaya during the period January 2019 to December 2020. The data of age, gender, anatomical variations of paranasal sinuses and Keros classification of 55 patients who met the inclusion and exclusion criteria were obtained and recorded. The most common paranasal sinuses anatomical variations were deviated nasal septum (71%), concha bullosa (27%) and ager nasi (22%). Genderwise, anatomical variations were seen more in males. Based on Keros classification, type II(47%) is the most frequently found. The high incidence of paranasal sinuses anatomical variations, emphasize the need for proper preoperative assessment for safe and effective endoscopic sinus surgery.
