Introduction: Middle turbinate is an important landmark of lateral nasal wall during endoscopy. The aim of this study was to examine the surgical anatomy of middle turbinate in hemisected heads which allows better visualization of the middle turbinate and middle meatus and to provide anatomical knowledge to the surgeons performing Endoscopic Sinus Surgeries (ESS) and middle turbinectomies. Method: The openings of paranasal sinuses in middle meatus were studied in 100 hemisected adult Indian cadaveric heads. Results: The mean angles between the lowermost portion of limen nasi and openings of frontal sinus i.e. f’, middle ethmoidal cells i.e. m’, maxillary sinus i.e. s’ were 64.8°, 46.71°, 38.59° respectively. The mean distance between the lowermost portion of limen nasi and openings of frontal sinus i.e. f, middleethmoidal cells i.e. m, maxillary sinus i.e.s.are 41.07 ± 4.86 mm, 43.56 ± 3.8 mm, 36.84 ± 3.96 mm.The difference observed in the readings for the two sides is not statistically significant.

Three percent cases showed two middle ethmoidal cell openings.Fivepercentcases showed dual maxillary sinus openings.Fourpercent cases showed absence of maxillary sinus openings.
