Fibular Dimensions for Mandibular Reconstruction among Filipinos
Keywords:Mandibular reconstruction, Fibula, Free Flaps, Fibular bone dimensions, Filipino
Objective: To determine if the anatomic dimensions (length, cross-sectional width, cortical
thickness) of the Filipino fibula are ideal for mandibular reconstruction.
Design: Cross-sectional study
Setting: Anatomy dissection laboratory
Patients: 40 fibulas from 20 adult cadavers
Results: Morphometric examination showed the mean length of the harvested fibulas was 33.5 cm. The mean horizontal (a-d) and vertical (b-c) widths of the proximal cross-section (point B) were 15.1 ± 0.28 mm and 9.9 ± 0.15 mm respectively. The mean horizontal (a-d) and vertical (b-c) widths of the distal cross-section (point D) were 15.4 ± 0.24 mm and 10.3 ± 0.49 mm respectively. The mean cortical thickness of the anterior (a), lateral (b), posterior (c) and medial (d) aspects of the proximal cross-section (point B) were 5.2 ± 0.1 mm, 3.2 ± 0.04 mm, 3.6 ± 0.01 mm, and 2.9 ± 0.06 mm respectively. The mean cortical thickness of the anterior (a), lateral (b), posterior (c) and medial (d) aspects of the distal cross-section (point D) were 5.1 ± 0.21 mm, 3.1 ± 0.11 mm, 3.5 ± 0.04 mm, and 2.9 ± 0.09 mm respectively.
Conclusion: Our findings show that the Filipino fibulas studied have dimensions that are ideal for mandibular reconstruction.
