Abstract
Purpose: This observational, cross-sectional study evaluated healthy Caucasian Brazilian individuals' normal lip dimensions according to sex and age (20-50 years) using stereophotogrammetry.
Methods: A total of 130 individuals divided into four groups according to sex and age were analyzed using stereophotogrammetry. Ten linear lip, five angular lip, and three lip surface measurements (upper, lower, and total lip vermilion) were obtained. Comparisons were performed using two-way ANOVA.
Results: Mouth width, philtrum width, and lower lip cutaneous height were significantly greater in men than women. The upper lip height, upper lip cutaneous height, and average lower vermilion lip angle were significantly larger in men than women and increased with age (group), with medium or large effect sizes. A sex × group interaction was present for total vermilion height, upper vermilion height, total lip height, lower lip height, average upper vermilion lip angle, average Cupid's bow angle, mentolabial angle, and upper and total vermilion lip areas. When factors interact (sex/group), one affects the outcome of the other.
Conclusions: Relevant linear lip measures were greater in men than women and increased with age in a mixed population from 20 to 50 years old. Thus, the lip and mouth are severly impacted by aging.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
