Morphologic And Morphometric Parameters Of Lateral Wall Of Nose Including Ostiomeatal Complex An Anatomical Study With Clinical Correlations

Abstract

The distances from various bony landmarks in cadaveric heads and CT scans, along with their mean with standard deviation for male and female subjects have been observed. The mean distance between the LMT and UIT landmarks was significantly higher in cadaveric heads compared to CT scans, (t- 4.34 and p- 0.0003). Similarly, the mean distance between the SO from CH landmark was significantly higher in CT scans compared to cadaveric heads, (t-3.15 and p- 0.007). However, for some landmarks, such as the SO - CS landmark, there were no significant differences in distance between the two groups, as indicated by the low t-values and high p-values. newlineVarious morphological parameters of the lateral wall of the nose between cadaveric heads and CT scans of both sexes were observed. There was a statistically significant (Chi-squared test, *pand#8804; 0.05) difference in the presence of hypertrophied MT on the left side, morphological changes in maxillary ostia on the left side, morphological changes in the uncinate process on both sides and elevation formed by onodi cells on the right side in males. newlineSimilarly, significant association was observed for various morphological changes of lateral wall of nose in female cadaveric heads as well as CT scans. newlinePresence of inter sinus septa of sphenoid air sinus (SS) and morphological changes of sphenoid ostia (SO) (number) have been also examined in the current study in cadaveric heads and CT scans of both sexes. Apart from that, variations of SO and a rare variation named as multiple/double ostia was also observed. newline
