Preauricular Aging: A Three-Point Grading System to Guide Treatment in Facial Rejuvenation

Aging affects the face in all its dimensions. However, more has been published about the improvement of the periocular, midface, and perioral aging changes. We believe the profile view, particularly the preauricular area, is of great value when assessing the need for facial contouring procedures, as well as their effectiveness.

To develop and evaluate a classification based on the aging changes around the preauricular area, which aims to provide an objective direction to the appropriate treatment method.

All patients who attended the clinic for different aesthetic procedures between June 2019 and January 2020 were photographed. Two non-treating dermatologists and two non-treating plastic surgeons were asked to evaluate the perceived aging of the preauricular area using a three-point grading system. The assessment of each photograph was made once by each evaluator, and the inter-rater correlation was calculated.

A total of 158 profile pictures of the preauricular area of 158 patients were evaluated by two non-treating dermatologists and two non-treating plastic surgeons. The inter-rater correlation was excellent at 0.942. The mean grading system of the patient samples was 1.42, with a standard deviation of 0.9 and a variance of 0.001.

The preauricular area is often overlooked and undertreated. Our results demonstrate an excellent inter-rater correlation between plastic surgeons and dermatologists at assessing the degree of aging in the area. This relatively hidden lateral area can serve as a test point, evaluating response to selected treatment before proceeding to full-face intervention. We suggest using a simple three-point scale to help guide treatment of the preauricular area and as part of our holistic approach to facial rejuvenation.
