Abstract
Background: Estimation of intercanthal width and biocular breadth from digital photography is important in the evaluation of several systemic syndromes, craniofacial abnormalities and in surgical treatments of post-traumatic telecanthus. Dysmorphologists employ canthal measurements in evaluating the degree of hypertelorism. So intercanthal width and biocular breadth values are very important for clinicians, ophthalmologists, plastic and reconstructive surgeons. The reliability of estimation of intercanthal width from biocular breadth by using multiplication factor is high.Objective: To make an attempt to determine the multiplication factor for estimation of intercanthal width.Materials and method: This is a cross sectional study conducted in the Anatomy department of Sir Salimullah Medical College, Dhaka, Bangladesh from January 2010 to June 2011. One hundred Bangladeshi 25 to 45 years old women were selected purposively for the study.Results: The mean±SD intercanthal width was 3.456±0.3585 cm. Multiplication factor for measuring intercanthal width from biocular breadth (9.348±0.7174 cm) was 0.369±0.0232 cm. The mean±SD of estimated intercanthal width was 3.449±0.2647 cm. No significant difference was found between the measured and estimated intercanthal width.Conclusion: Multiplication factor can be used to determine intercanthal width in Bangladeshi women though agreement test would have been done to generalize the finding.Delta Med Col J.

Highlights
Facial anthropometric studies provide a quantitative description of craniofacial complex and these studies in different populations have stated the proportional correlations among different measurements of face.[1]Deformities of the face are most often congenital but may result from trauma, burn, neoplasm or any pathology involving the facial skeleton
The photograph was taken after the subject was seated comfortably on a chair looking straight to the camera which was fixed on its stand at the same level of the subject’s head having a distance of 120 centimeter, both eyes opened and mouth closed with a fixed focus, zoom and illumination
Intercanthal width and biocular breadth of the subjects were measured by digitizing points at endocanthion, exocanthion of both eyes and horizontal lines were drawn on the above mentioned points and photographic measurements were recorded by using the computer programme Adobe Illustrator Version-10
