It is often suggested that the frontal sinus morphology of no two individuals is alike, and that the configuration of the frontal sinus is as unique to an individual as his or her fingerprints. However, no empirical, quantitative testing of the uniqueness of frontal sinus outlines has ever been performed. Such testing is necessary for frontal sinus identifications to be admissible in many courts. This study investigated frontal sinus outline variability using elliptic Fourier analysis (EFA), a geometric morphometric approach that fits a closed curve to an ordered set of data points, generating a set of coefficients that can be used to reproduce the outline. Two-dimensional representations of 808 frontal sinuses (as seen in posterior-anterior cranial radiographs) were digitized, and differences in their shapes were assessed quantitatively by comparing the Euclidean distances between EFA-generated outlines. Results show that Euclidean distances between outlines of different individuals are significantly larger than those between replicates of the same individual, and typicalities show that the probability of finding two different individuals with Euclidean distances less that that between a particular case's replicate is very small. Thus, there is a quantifiable and significant difference between the shapes of individuals' frontal sinus outlines
