The variants of paranasal sinuses (PNS)and nasal cavity are of clinical importance since some variants are susceptible to recurrent infection. Moreover, during functional endoscopic sinus surgery, knowledge of anatomy is of utmost importance in order to prevent injury of vital structures like optic nerves, carotid arteries etc. However, there is lack of study enrolling adequate number of patients in our country.
