External Ear Anthropometry of Healthy Turkish Young Adults.

PURPOSE: The aim of this study was to determine the external ear values in Turkish young adults with 2-dimensional photogrammetry. METHODS: One hundred males and 100 females aged between 18 and 25 years were included in the study. Individuals were photographed from both sides. Ear length (superaurel-subaurel, spa-sba ), ear width (preaurel-postaurel, pra-pa ), and the angle between the vertical axis of the auricle and the line between spa and sba (ear incline angle, eia ) were measured in these photographs. Also, auricular index ( pra-pa / spa-sba ×100) was calculated. RESULTS: The average values of the spa-sba, pra-pa , eia , and auricular index were found as 65.46±4.68 mm, 37.89±3.61 mm, 19.40±4.83 degrees, and 57.93±4.53 in males and 60.90±5.35 mm, 35.62±3.69 mm, 17.95±4.86 degrees, and 58.65±5.29 in females, respectively. While the values of spa-sba ( P =0.001 for the right side and P =0.001 for the left side), pra-pa ( P =0.001 for the right side and P =0.001 for the left side), and eia ( P =0.024 for the right side and P =0.041 for the left side) were statistically higher for males than females, there was no statistically significant difference between the sex and the auricular index ( P =0.404 for the right side and P =0.955 for the left side). Besides, there was no statistically significant difference between the sides for these 4 parameters ( P =0.760, 0.409, 0.225, and 0.521, respectively). CONCLUSION: The authors believe that the results obtained for Turkish young adults can be used as reference values, which can be used in the diagnosis, follow, or surgical treatment of many diseases, forensic procedures, and planning esthetic surgery procedures.

Lip Anthropometry of Healthy Turkish Young Adults.

ABSTRACT: The lips play an important role in evaluating and recognizing the craniofacial complex and our perception of facial beauty and attractiveness. The aim of this study was to evaluate the anthropometric measurements of the lips of Turkish young adults and to look for sexual dimorphism. Anterior view photographs were taken of 100 females and 100 males who volunteered to participate in the study. Seven landmarks were determined, stomion (st), sublabiale (sl), subnasale (sn), labiale superius (ls), labiale inferius (li), crista philtre (cp), and chelion (ch). Then, using these landmarks, lower lip height (st-sl), upper lip height (sn-st), philtrum length (sn-ls), upper vermilion height (ls-st), lower vermilion height (li-st), cutaneous lower lip height (li-sl), philtrum width (cp-cp), and mouth width (ch-ch) were measured. It was observed that there was a statistical difference between genders in the parameters of st-sl, sn-st, sn-ls, li-sl, and ch-ch (P = 0.001, for these parameters). Besides, using these distances, 6 anthropometric ratios (ls-st/li-st, sn-ls/ls-st, li-sl/li-st, sn-st/st-sl, cp-cp/ch-ch, and ls-li/ch-ch) were calculated. Among the ratios investigated, sn-ls/ls-st, li-sl/li-st, and cp-cp/ch-ch were statistically significantly larger in males compared females (P = 0.012, P = 0.002, and P = 0.001, respectively). We believe that the results obtained in this study regarding lip anthropometry will help determine the standard values that can be used for the Turkish population aged 18 to 25.

External Nose Anthropometry of Healthy Turkish Young Adults.

ABSTRACT: Although many studies in the literature examine distances and angles about the nose, there are no clear standard values for different races and ethnic groups. The aim of this study is to determine the anthropometric measurement standards related to the external nose in Turkish young adults between the ages of 18 and 25. The subjects participating in this study were 100 female and 100 male volunteers. Six landmarks (nasion, subnasale, pronasale, alar, subalar and maxillofrontale) on the nose were chosen, and these landmarks were identified on the photographs. Then, using these landmarks, a total of seven distances (nose height, dorsum of nose length, distance between the subnasale and pronasale, nose width, right nostril floor width, left nostril floor width and root of nose width) and four angles (nasofrontal, nasofacial, nasomental and nasolabial angles) measurements were made. There were statistically significant differences between gender in nine parameters. One parameter (nasofrontal angle) is higher in females, and seven parameters (nose height, dorsum of nose length, nose width, right nostril floor width, left nostril floor width, root of nose width and nasofacial angle) are higher in males. It is accepted that distances and angles about the nose differ according to race and ethnicity. The authors believe that the results obtained in this study will help determine the standard values that can be used for the Turkish population between the ages of 18 and 25.

Craniofacial Anthropometry of Healthy Turkish Young Adults: Analysis of Head and Face.

ABSTRACT: The aim of this study was to evaluate the craniofacial anthropometric measurements of Turkish young adults between the ages of 18 and 25. Anterior view and side profile photographs were taken of 100 females and 100 males who volunteered to participate in the study and had no craniofacial anomalies, history of facial trauma, or history of orofacial surgery. Thirteen landmarks on the face and head were chosen, and these landmarks were identified on the photographs. Then, using these landmarks, a total of 19 distance measurements were made, 16 from the anterior view, and 3 from the side profile. There were statistically significant differences between the sexes in 13 parameters: 2 parameters (t-n and ft-ft) being higher in females and 11 parameters (v-n, v-t, t-gn, sn-gn, n-gn, st-gn, sl-gn, fz-fz, z-z, tr-tr and go-go) being higher in males. Also, 7 facial anthropometric ratios were calculated. There were statistically significant differences between the genders in all ratios. The literature reveals that craniofacial anthropometric measurements have been performed on many different populations and that there are numerous differences between the results of the studies conducted. We are of the opinion that the results obtained in this present study will contribute to the literature by helping to determine the standard values for the Turkish population between the ages of 18 and 25, which can be used in diagnosis, treatment and postoperative evaluation in areas such as forensic science, orthodontics, clinical genetics, maxillofacial surgery, and plastic surgery.
