New Landmarks for the Surgical Creation of Dimples Based on Facial Form.

Dimleplasty is the surgical creation of dimples. The demand for dimpleplasty has increased over the past few years. Despite this increasing demand, the most widely used reference point for determining where to place a surgically created dimple, the Khoo Boo Chai (KBC) point, dates back more than 60 years. The aim of our study was to assess the facial shape of a sample of men and women, all of whom had natural dimples, to determine if characteristic patterns in dimple size, location, and shape existed according to each specific facial shapes. For our study, 1,194 people were examined for dimples and of these, 216 individuals with a group total of 336 naturally occurring dimples were included in the study. Facial form was categorized as mesoprosopic, euryprosopic, or leptoprosopic. We found that 54.8 percent of the total dimples were not positioned on the KBC point. In mesoprosopic group, out of 204 dimples, 117 were not positioned on the KBC point (87 were); in leptoprosopic group, out of 66 dimples, 30 dimples were not positioned on the KBC point (36 were); and in the euryprosopic group, out of 66 dimples, 36 were not positioned on the KBC point (30 were). Most of the dimples in the mesoprosopic group were positioned 4mm anterior to the KBC point, and in the eryprosopic group, most dimples were positioned 3mm above and behind the KBC point. Most of the dimples in the leptoprosopic group were positioned on the KBC point. We also observed differing patterns in size and shape between the groups. Understanding these differences could help surgeons achieve optimal outcomes by creating more natural looking and thus more aesthetically pleasing dimples among their patients seeking dimpleplasty.
