Abstract

© 2017 The American Society for Aesthetic Plastic Surgery, Inc. Background: The purpose of this study was to attempt to determine a reliable method of evaluating midface position. We assessed a novel parameter called WIZDOM (Width of the Interzygomatic Distance of the Midface) and its relationship to other facial metrics. Objectives: The goal was to evaluate midfacial position quantitatively in women by examining 2-dimensional photographs of a subset of women with idealized facial proportions. Methods: Three examiners analyzed stock photographs of nonsmiling female model faces. Numerous parameters were analyzed for each photograph, including: interpupillary distance, medial canthus (MC) to lip, brow length, WIZDOM, WIZDOM to MC, WIZDOM to hairline, WIZDOM to chin vertical, and lateral brow to WIZDOM. Meaningful relationships between various parameters were statistically analyzed. Examiner measurements were assessed for interobserver reliability. Results: Fifty-five female model photographs were included in the analysis. The average interpupillary distance was 59.2 mm ± 3.54 (range, 50.5- 67.3 mm). The WIZDOM average was 108 mm ± 5.81 (range, 93-127 mm) and brow length was 107 mm ± 5.87 (range, 96.7-124 mm). The difference between brow length and WIZDOM was not statistically different (P = 0.834). The interobserver reliability between the 3 examiners was excellent for all parameters (P < 0.01), ranging from 0.718 (WIZDOM-MC) to 0.993 (interpupillary distance). The WIZDOM measurement was reproducible with an interobserver coefficient of 0.939. Conclusions: WIZDOM can be used to quantify aesthetically desirable midfacial position in patients and can be used as a measurement to aid in assessment and as an ideal to achieve balanced aesthetic results in midface restorative procedures-lifting or volumization-in females.
