| Summary: | Introduction: The frontal sinus is a well-preserved structure, hence making it a potential site of choice during forensic identification. The coexistence of 2-dimensional (2D) and 3-dimensional (3D) models from imaging has gained interest for forensic usage. Despite the existing comparison between 2D and 3D models, the comparison using frontal sinus within the same patient is yet to be explored. This upsurges a key question on the morphological consistency of 3D over 2D models on the frontal sinus. This pilot study compares the consistency of frontal sinus morphology between 2D and 3D frontal sinus reconstructed models. Methods: The samples comprised 30 digital skull radiographs and CT scans of the same subject. The 3D models of the frontal sinus were reconstructed from CT scans. The 2D and 3D models were superimposed, and the congruence of the morphological features was assessed in a superimposed state using a mix and wipe method. Results: The superimposed frontal sinus morphology on the 2D and 3D models shows a perfect match of 100% in the posteroanterior view. In the lateral view, 77% of the samples failed to match. Conclusion: The 3D frontal sinus model is more recommended to evaluate the frontal sinus region compared to the 2D model. © 2024 Universiti Putra Malaysia Press. All rights reserved.
