Quantification of Bending Tolerance of the Cartilaginous Nasal Septum: Computer-Based Measurements (original) (raw)

Objective: Nose deformity, including nasal deviation, is conspicuous since it locates in central face area. Regarding this and its prevention, nasal septum is one of the important supporting structures. Understand bending tolerance of the cartilaginous septum not only helps mitigate secondary deformity from surgical intervention, but also provides baseline information for further study regarding the nasal septum.Materials and Methods: Nineteen fresh cadavers were dissected to expose the cartilaginous nasal septum. It was connected with the set-up computer system for detection of electrical signal at 1-mm septal bending from the midline. Mechanical load (bending load) was applied over the dorsal septum to quantify its bending tolerance. The data of bending tolerance and Pearson’s correlation were reported.Results: The mean of septal thicknesses is 1.5 ± 0.4 with the average bending load of 19.0 ± 11.2 g. The majority of the septal thicknesses (15/19; 78.9%) of the dissections are wit...
