Objective: To report anatomical variations on routine CT Scans observed in the paranasal sinuses in patients presenting to a tertiary care facility.

Methods: A cross-sectional study conducted at the department of radiology of a tertiary care centre, intended to evaluate anatomical variations in patients with benign Sino-nasal pathologies presenting to the facility between 1st of August, 2016 and 31st of July, 2017. The data was collected by evaluating digital records of patients collected over the specified time.

Results: A complete analysis of the cross-sectional radiological examinations of 70 patients was carried out for the evaluation of anatomical variants prevalent in the population subset. The study included 44 males and 26 females with a median age of 35.8 years. Among the study population, 71.24% had a deviated septum with right-sided predominance, 35.71% with concha bullosa, 21.42% had septated maxillary sinus, 70% had agger nasi cells, 20% had haller cells, 18.57% had onodi cells and lastly 2.85% had hypertrophied ethmoid sinuses. A differentiation of olfactory fossa depth was also studied and characterized as per the Kero’s classification in which type-II was the predominant variety corresponding to 71.42% of the test subjects.

Conclusion: Knowledge of these variations preoperatively is of utmost importance for surgeons and failure to pay attention to these details can end up in devastating complications. Such studies can optimize patient care and can lead to reduction in adverse sequalae of surgical intervention.
