Aim: To determine the incidence of concha bullosa in the CT scans ordered in the hospital in a certain period.
Study design: This was a cross sectional study.
Place and duration of study: the study was conducted in the out patients’ department of the Doctors Hospital, Lahore.
The study was conducted from March 2019 till May 2019.
Methods: Patients presenting in the ENT out patients department in the prescribed period and who were ordered a CT scan of the paranasal sinuses had the concha bullosa recorded as present or not and if it was one sided or was present on both sides.
Results: A total of 33 CT scans were thus examined. The age ranged from 12 years to 75 years old patient. There were 19(57.5%) female patients and 14 (42.4%) male patients who had their CT scans recorded for concha bullosa. The incidence of a Concha Bullosa present out of the total CT scans performed was 18.18% whereas, the incidence in females was higher at 28.57% whereas it was 10.52% in the males.
Out of the total CT scans with identifiable concha bullosa 16.6% were bilaterally present and the concha was unilaterally present in the majority of the CT scans examined (83.3%).
Conclusion: There is enormous variation in the incidence of concha bullosa as is evident from data from various countries. There is variation from a single country even. Further studies may be able to determine the cause of this anatomical variation.
