Kamal Singh, Aarti Rohilla and Jyoti Rohila

The adult human skeleton is sexed using morphological and metrical traits of big intact bones like skull, mandible, pelvis and long bones etc. The Incus is housed in the middle ear; so it remains well protected even in the mutilated bodies. Morphometry of the 120 human Incus bones from 60 cadavers have been studied with the aim to know thesexual dimorphismin north Indian population. It is observed that study of normal dimensions and indices will provide insight for the surgeons and will have surgical implications in reconstruction of ossicular chain, which may have been congenitally absent, malformed, fixed, disrupted or destroyed by trauma or disease. These are the results for guidance and future manipulation in the field of ENT and Forensic Medicine.
