From Structure to Aesthetics: The Importance of Nasal Bone Thickness in Rhinoplasty Planning

Background: Correct performance of rhinoseptoplasty often requires osteotomy, the effectiveness and safety of which depend on precise knowledge of nasal anatomy, particularly the shape, length, and thickness of the nasal bones. Aim: The aim of this study was to assess the morphometry of the nasal bone and nasal pyramid in adult patients based on three-dimensional computed tomography (CT) using Slicer 3D software. Materials and Methods: A retrospective analysis was performed on data from 87 patients (44 women and 43 men; mean age 50.64 SD ±16.7 years) who underwent head CT between 1 January 2024 and 31 December 2025 because of trauma (to exclude intracranial hemorrhage) or dizziness (to diagnose central causes). Results: The comparative analysis demonstrated statistically significant differences in the dimensions of the nasal bony structures between women and men, with women showing lower values for all assessed parameters. For point 1L, the mean value was 6.29 in women compared with 8.07 in men (p = 0.0056). For point 4L, the values were 2.07 vs. 2.55, respectively (p = 0.009), whereas for point 5L they were 1.52 vs. 1.66 (p = 0.01). A similar relationship was also noted on the right side: for point 1R, the values were 5.95 vs. 8.02 (p = 0.03), and for point 5R they were 1.54 vs. 1.89 (p = 0.03), confirming consistently smaller dimensions of the bony structures in women in the analyzed study group. Conclusions: The obtained results may have important practical significance in planning osteotomy during rhinoseptoplasty procedures, enabling a more precise and safer surgical procedure.
