It is clear that the Superior Temporal Artery (STA) [1-4] represents 85% of the vascular supply to the scalp, whilst the remaining 15% is provided by the Occipital Artery (OA). In healthy Class I skeletal relationship (Figure 1), there is adequate clearance (3.5 mm) between the base of the skull, and the eminence of the condyle, to allow for adequate perfusion of the scalp by the STA [5]. However, in the instance of Class II Skeletal malocclusion, there is the possibility of reduced perfusion or occluded blood flow in the STA, due to the retrognathic architecture of the skull. Evaluation of the population reveals that hair loss is seen overwhelmingly among individuals with Class II skeletal profile, supporting the hypothesis that malocclusion leading to reduced vascular perfusion of the scalp in turn results in hair loss (Figure 2).
With respect to the control group, only those individuals with no prior experience of orthodontic treatment, with a minimum age of thirty years, and with Class III Skeletal jaw relation were selected for inclusion. A total of fifty individuals with no hair loss were selected for inclusion, and served as the control group (Figure 3).
Results
Of the one hundred individuals suffering from hair loss, direct visual, and observation of dental model occlusion demonstrated that ninety-six individuals had Class II dental malocclusion. However, a more thorough evaluation of the one hundred individuals, those with or without Class II dental malocclusion, through analysis of their skeletal cephalometric radiographs, reveals that all one hundred subjects selected for inclusion present with Class II skeletal malocclusion (Figure 4).
Of the fifty individuals presenting with no hair loss, all subjects present with a Class III skeletal relationship, upon evaluation of their dental and skeletal occlusal records.
A reminder that bald men suffe suffer from higher risk of strokes.
