Abstract
Objective:
To compare the harvestable donor septal cartilage among patients.
Background:
Trends in donor septal cartilage anatomy are not well quantified in the literature.
Methods:
Harvestable septal cartilage area and length (preserving a 1-cm L-strut) were measured on fine-cut maxillofacial computed tomography (CT) for 200 patients in four self-described racial/ethnic groups: African American, Asian American, European American, and Latin American. Height, sex, and age were recorded. Demographic variables were modeled by multivariate logistic regression to determine characteristics predictive of harvestable septal cartilage.
Results:
Older age, shorter height, African American or Asian American self-described race, and female sex were independently associated with smaller harvestable area and shorter length (all p < 0.05). On multivariate regression, Asian American [odds ratio (OR) 5.23, p = 0.005] and African American (OR 3.75, p = 0.015) patients were more likely than Latin American or European Americans patients have a smaller harvestable area. Age (OR 1.02, p = 0.043) and height (OR 0.94, p = 0.029) were also correlated with smaller cartilage area and length, respectively.
Conclusions:
CT scan and demographic characteristics predicted donor septal cartilage availability.
