“…The Brazilian mean values for both sexes were discretely higher than those detected for young Chinese and Korean subjects [17] and similar to other studies [1, 5, 10, 14]. Similarly, men presented a higher mouth width value compared to women [19, 21], with a mean difference of up to 5 mm. Although some parameters showed similarity to those of foreign populations, others differed, even if discretely.…”

“…This does not imply that the ls-li values between men and women are statistically different, but this heteroscedasticity suggests that separate analysis would be more adequate to document the anthropometric data of each population. Other studies found differences between the genders, whether for ls-li or other variables, and in which the male values repeatedly assumed higher values [1,10,16–17,21]. …”

“…For PM-SD and ID-SM, the authors attempted to verify proportions based on the growth of alveolar processes and their reduction with age [21,30] versus the similar tendency of the height of the vermilion borders, li [1, 10, 16]. The authors found a narrower interval of confidence that may make the estimate of ls-li applicable by attributing 85% of its value to PM-SD in men and 88% of its value to PM-SD in women.…”

The oral cavity’s importance in defining the facial region makes it a primary feature for forensic facial reconstruction (FFR). The aim of this study is to construct a pattern of reference for dimensions and proportions of the lips and establish parameters that may help estimate the vermilion borders’ height dimensions and the mouth’s width. By means of cone beam computed tomography, divided into two samples: sample 1 (n = 322; 137 male, 185 female) verified the linear distances delimited by anatomical landmarks in soft tissue. The sample 2 (n = 108; 40 male, 68 female), verified the proportions among the height of the vermilion borders, width of the mouth, and linear distances between craniometric landmarks in hard tissues, both from a Brazilian database. The measurements were completed using OsiriX, and the results were analyzed by means of descriptive statistics at a level of significance of 5%. The height of the vermilion borders corresponded to approximately 26% of the width of the mouth. The width of the mouth increased over the course of time in men and remained stable in women. In men, a mean intercanine distance of 75% of the total mouth’s width was found; for women, it was 80%. The parameters of the relations between soft and hard tissues in the oral cavity region presented that the distance between landmarks ID-SM (Infradentale-Supramentale) corresponded to 55% of the height of the vermilion borders of the mouth for both sexes, while the distance between landmarks PM-SD (Philtrum medium-Supradentale) corresponded to 85% in men and 88% in women. Mean values of 97% of the width of the mouth in women and 93% in men were attributed to the distance between the mentonian foramina. It was not possible to estimate the height of the labial vermilion borders by the bone measurements, FIs-Fli (Foramen incisivus superius-inferius) and NS-GN (Nasospinale-Gnathion). Profound knowledge of the anatomy and morphology of the oral cavity may contribute to increasing the precision of FFRs and help with human identification.

“…1 Modifications of facial structures continue in the early adulthood. 2,3 In addition, age-related facial changes have been reported to occur as early as 20-years old and extend thereafter. 4 It is to the interest of plastic and orthopedic surgeons to quantify the normal patterns of facial changes overtime for the purposes of diagnosis and treatment.…”

Human faces are under a constant state of change throughout the entirety of one's lifetime. Photogrammetry has been advocated for use in large epidemiological studies investigating facial characteristics. This study aimed to review existing longitudinal photogrammetric studies in terms of the measurements selected and the observed facial changes overtime. A comprehensive literature search was performed in 4 databases, PubMed, ISI Web of Science, EMBASE, and Scopus, which was supplemented by hand search. No limitations were set as to the language, dates, or status of publication. The records were assessed for the eligibility and rated for the risk of bias by 2 independent reviewers. Data regarding study characteristics, measurements selected and the outcomes reported, were extracted for analysis. An initial search identified 5127 studies. After 2 rounds of study screening, 6 eligible studies informed this review. The risk of bias of the studies ranged from 41.7% to 80.8%. Only 1 study performed sample size calculation, and only 17% of the studies had a sample size of over 30 subjects. Confidence interval was reported by none of the studies. The facial features assessed varied among the studies, and some studies focused on only specific regions of the face. Photogrammetry has been used by a limited number of studies in the analysis of longitudinal soft tissue facial changes. Moreover, these studies are heterogeneous with respect to their levels of risk of bias and the facial features assessed. Recommendations are provided to improve the qualities of future photogrammetric studies.
