Abstract:
Introduction: Race estimation of unknown individual is essential in forensic investigation. The resiliency of frontal
sinus makes it a potential tool for biological profiling, particularly in cases where fragmented skeleton persists. Geometric morphometrics is an efficient way to characterise shape. However, the use of frontal sinus to identify race of
Malaysians is yet to be investigated. This research employed a two-dimensional (2D) geometric morphometric to
examine the morphological differences of the frontal sinus among the major races in Malaysia. Methods: Lateral skull
radiographs which comprising of 453 adult Malaysian (151 Malays, Chinese and Indian respectively) were used. The
2D landmarks of eight were placed on the digitalized radiographs and 2D geometric morphometric analysis was
performed using MorphoJ software. Results: Procrustes ANOVA revealed a significantly different frontal sinus shape
(p-value < 0.05) between races. Canonical variate analysis showed significantly different frontal sinus morphology
(p-value < 0.05) between Malay and Indian as well as Chinese and Indian. Discriminant function analysis with
cross-validation demonstrated a 57.4% accuracy rate. Conclusion: This population-specific study based on frontal
sinus of Malaysians using the 2D geometric morphometric, though less reliable, sheds new light on the potential
applicability of this method for race estimation purpose.
