The Clinical Analysis of the Nasal Septal Cartilage by Measurement Using Computed Tomography

Abstract

BackgroundThe nasal septal cartilage is often used as a donor graft in rhinoplasty operations but can vary widely in size across the patient population. As such, preoperative estimation of the cartilaginous area is important for patient counseling as well as operating planning. We aim to estimate septal cartilage area by using facial computed tomography (CT) studies.MethodsThe study was performed using facial CT images taken from 200 patients between January 2012 to July 2015. Using the mid-sagittal image, the boundary of cartilaginous septum was delineated from soft tissue using the mean difference in signal intensity (or brightness). The area within this boundary was calculated. The calculated area for septal cartilage was then compared across age groups and sexes.ResultsOverall, the mean area of nasal septal cartilage was 8.18 cm2 with the maximum of 12.42 cm2 and the minimum of 4.89 cm2. The cartilage areas were measured to be larger in men than in women (p<0.05). The area decreased with advancing age (p<0.05).ConclusionMeasuring the size of septal cartilage using brightness difference is more precise and reliable than previously reported methods. This method can be utilized as the standard for prevention of postoperative complication.

“…1,11,13 This overlap decreased with age, which is probably because of the gradual ossification of the septal cartilage along the junction between the septal cartilage and the perpendicular plate of the ethmoid bone. [16][17][18] This measurement did not differ between subgroups with and without a nasal hump, which Palhazi et al have also reported. 1 Lazovic et al described two different types of nasal bones: S-shaped nasal bones and V-shaped nasal bones.…”
