“…21,23 The various morphometric results of bisexual and bilateral values of stapes were compared with previous researchers are shown in Table 5. Although results of morphometric analyses did not reveal much statistically significant level of sexual dimorphism, but on discriminant functional analysis it is found that stapes bone can be used as a tool for determination of sex with a good accuracy similar to the findings of Singh et al 24,25 …”

Background: Sexing of human skeleton is highly contested subject and is usually done by using morphological and metrical traits of big intact bones like skull, mandible, pelvis and long bones etc.1 The stapes remains well protected by being housed in the middle ear, even in the mutilated bodies.Methods: The morphometric study of the 120 human stapes bones from 60 unidentified cadavers was aimed to know the presence of sexual dimorphism.Results: The weight and measurements of footplate could be a good criterion for determining percentage accuracy as male and female respectively and could be used as a potential tool for determination of sex.Conclusions: The study of normal dimensions and indices of stapes will provide insight to the forensic experts for deciding the sex of an individual in the disputed cases. Our findings are the results for guidance and future manipulation in the forensic and legal medicine.

“…In that study, mean of total length of incus was 6.43 mm with SD 0.29 mm, mean of total width of incus was 4.99 mm with SD 0.32 mm and mean of maximum distance between the processes of incus was 5.82 mm with SD 0.44 mm. Singh K et al [9] in 2016 measured the total length, total width, maximum distance between the processes and index of incus in population of Haryana, India. In that study, mean of total length of incus was 6.674 mm, of male right side was 6.691 mm with SD 0.419 mm, of female right side was 6.656 mm with SD 0.33 mm, of male left side was 6.682 mm with SD 0.498 mm and of female left side was 6.666 mm with SD 0.334 mm.…”

Background: The incus is the intermediately placed ear ossicle in the middle ear cavity between the malleus and the stapes.Materials and Methods: In present study, various measurements of incus were taken for the purpose of sexual dimorphism. Out of total 60 incus used in the present study, 30 were retrieved from the male cadavers and 30 were retrieved from the female cadavers.Results and Discussion: Mean of total length of incus, mean of total width of incus, mean of maximum distance between the tips of the processes of incus and mean of index of incus in male are more as compared to female in the present study.Conclusion: Among all the measurements taken in the present study; total length of incus and total width of incus having statistically significant difference between the male and female incus and both can be used for the sexual dimorphism of incus for Kachchhi Gujarati population of present study. KEY WORDS: Total length of incus, Total width of incus, Maximum distance between the tips of the processes of incus, Index of incus

Background: Sex determination has been the most intriguing puzzle for forensic pathologists and anthropologists for which efforts are being done since long. Sexual dimorphism is well established in the adult pelvis and it is known to provide the highest level of information about sexual dimorphism. This study was conducted to know whether this dimorphism exists in fetal bones? Method: A total of 34 pairs of fetal pelvis bones (22 Males + 12 Females), age ranging from 4 months to full term were collected from unidentified dead fetuses brought in the Department of Forensic Medicine for the routine medicolegal autopsies, to study for sexual dimorphism in the Department of Anatomy, Pt. B. D. Sharma PGIMS, Rohtak. Samples were divided in 2 age groups and various metric parameters were recorded with the help of digital vernier caliper. Data obtained was subjected to descriptive & discriminant functional analysis. Conclusion:Results of Descriptive and Discriminant Functional Analysis showed that sex determination can be done with 100% of accuracy by using different combinations of parameters of fetal ilium. This study illustrates that sexual dimorphism exists from early fetal life & after mid pregnancy; it can be clearly established by discriminant functional analysis. This research was limited in its analysis due to less availability of specimens as this represents only the results in north Indian population. Future studies should be done to explore different populations to better understand the sexual dimorphism in fetal bones of different geographic contexts.
