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.
