STUDY OF ANATOMICAL VARIATIONS OF LATERAL WALL OF NOSE BY ENDOSCOPE

Endoscopic examination of lateral wall of nose is usually required prior to endoscopic surgery on lateral wall of nose & paranasal sinuses. It demonstrates both the extent of disease(s) & anatomical variations that predispose to diseases & iatrogenic damage of nearby vital structure can be avoided. We conducted this study at Department of anatomy, Al-Ameen Medical College, Bijapur between March 2013 to December 2013. Adult 75 patients suffering with disease of sinuses & lateral wall of nose were included. Our study showed middle turbinate variation in 49.32 % of lateral wall of nose [concha bullosa 30.66%, paradoxically curved middle turbinate 18.66%)], large bulla ethamoidalis in 17.33 % & accessory maxillary sinus ostium in 13.33 % of lateral wall of nose. We came across concha bullosa as common variation. 82.62 % of concha bullosa & 53 % paradoxically curved middle turbinate gave rise to disease of sinuses which were statistically significant & 6 1 % of large bulla & 50 % of accessory ostia presented with diseases of sinuses which is statistically non significant
