Abstract
ABSTRACT
The anatomy of nose and paranasal sinuses is highly complicated and is most often
characterised by considerable anatomical variations. These variations have often
been linked to the aetiopathogenesis of inflammatory sinonasal pathology. Also
apart from diagnostic value, these variations also predispose the surrounding
critical structures to iatrogenic trauma during functional endoscopic sinus surgery
(FESS). Some of these variations also have a role in recurrence of disease. Computed
tomography (CT) is the mainstay of diagnosis and surgical planning for sinonasal
diseases, and a structured checklist to assess possible anatomic variants helps to
reduce the risk of surgical complications. Hence, we developed a checklist at our
centre with the mnemonic “SNOT RACE”.
