• Auricular reconstruction is a technically challenging and aesthetically demanding procedure as the ear has a complex anatomy. Anthropometry aids in achieving aesthetic ear reconstruction. We considered that implication of stereophotogrammetric technology will lead to a better understanding of human ear morphology. A cross-sectional study was conducted in our institutional OPD in a tertiary health care centre in the Northern part of India.400 people were chosen based on selection criteria. facial scans were done for 3D pictures using Canfield VECTRA® H2 3D imaging device. Study variables were assessed after marking landmarks on the 3D-generated auricular image of an individual. This study consisted of 55.5% males and 44.5% females belonging to the age group of 5–25 years (30.3%), 26–40 years (38.8%) and>40 yr (31.0%). Out of 400 cases, the majority had; oval shaped auricle, normally rolled helix, square earlobe; knob shaped tragus. The attached type of earlobe attachment was more in the right auricle (37%) and the partial attachment ear lobe was more in the left side auricle (35.5%). Darwin's tubercle showed more proportion in the case of males. The mean length and width of the auricle & attachment length are higher in males compared to females. Ear Angulation is highest among females. Assessment of ear morphology using technologically sound methods like stereophotogrammetry paves the way for a more quick, reliable and easy-to-use method for understanding ear morphology. Precise assessment of ear morphology using stereophotogrammetry helps in providing more cosmetic and acceptable ear restoration. [Display omitted]
