Morphometric analysis of various measurements of malleus on the basis of sexual dimorphism

Abstract

The malleus is the largest of the ear ossicles. In the present study, we tried to determine the normal range of the values of various measurements of malleus and whether these measurements are useful for the sexual dimorphism or not. Out of total 60 malleus used in the present study, 30 were retrieved from the male cadavers and 30 were retrieved from the female cadavers. Mean of total length of malleus, mean of length of manubrium of malleus and mean of length of head and neck of malleus in male are more as compared to female in the present study. Mean of index of malleus in male is less as compared to female in the present study. Among all the measurements taken in the present study; total length of malleus having statistically significant difference between the male and female malleus and it can be used for the sexual dimorphism of malleus for Kachchhi Gujarati population of present study.
