The knowledge of the facial angles is essential for safe and accurate plastic surgery interventions. Facial angles are used as a reference value for comparison during diagnosis and treatment planning. Also, the facial angles will provide valuable data in evaluation of facial aesthetics. So, the aim of this study was to determine the ideal values of the facial angles in Turkish healthy adults.METHODSTwo hundred and forty seven (129 females; 118 males) subjects aged between 18 and 25 years were included in this study. Frankfort horizontal plane was chosen to determine the angles related with face. Photographs were acquired using a Digital SLR Camera with fixed shooting values. (Canon EOS 80D; ISO 100 f/4.5). In all the shoots, a printed scale with known dimensions was present. Acquired images were then transferred to a computer station. Measurements were made using Image J 1.52a with 1/100 mm sensitivity. Statistical analysis was done using SPSS Ver. 22.00. A p<0.05 value was considered as significant. Student’s T Test was used to determine the significance between gender, while Pearson Correlation analysis was done to evaluate the relation between gender.RESULTSStatistically significant difference was found between the genders and the frontonasal angle, the nasofrontal angle, the nasolabial angle, the chin neck angle, and the nasal projection. Also, the fronto nasal angle, chin neck angle, and nasal projection measurements were higher in males than in females, whereas the nasofrontal angle and nasolabial angle were lower in males than in females. Additionally, there was a significant, negative very low correlation between fronto-nasal angle (-0.148), chin-neck angle (r=-0.179) and gender; a significant, negative and low correlation (r=-0.243) between nasal projection and gender, a significant, positive and low correlation between nasolabial angle and gender (r=0.259); and nasofrontal angle and gender (r=0.388).CONCLUSIONSFacial angle values of healthy population provide important and useful knowledge in terms of comparison of abnormalities clinically, and data may be valuable for the representatives of clinical disciplines.

Wormian (sutural) bones are accessory small bones located on the skull. These bones consist of extra ossification centers around cranial sutures. This study was carried out in 28 dry human skulls with unknown age and sex in the Department of Anatomy, Cukurova University. The aim of the study was to investigate incidence and to determine morphologic and morphometric characteristics of wormian (sutural) bones. Total incidence of wormian bone presence was 42.86 % (n=12) and most of them were located on lambdoid suture (57.14 %). Wormian bones were seen at lambdoid suture at a rate of 62.5 %, occipito-mastoid suture 9.37 %, asterion 18.76 %, lambda 9.37 %, and were not seen on pterion, bregma, parietotemporal, sagittal and coronal sutures. Wormian bones were seen on left side at a rate of 65.62 % and 34.38 % on right side of skull. According to our study, wormian bone shapes were seen as quadrangular (56.26 %), triangular (15.62 %) and irregular (28.12 %). The mean values of wormian bones were as follows; vertical diameter: 12.29±4.48 mm and horizontal diameter: 10.93±4.39 mm. For cephalic index, the result of our study shows that most of our skulls with or without wormian bones belong to dolichocephalic group. Knowledge of variations and characteristics of skull is important for forensic medicine, anatomy, radiology and neurosurgery fields and for literature data or clinical practices.

Beauty indicates a specific proportion system. It comprises facial height, width, and symmetry. A beautiful and an attractive face or facial morphology, which is affected by many factors such as social, cultural, ethnic, racial, climate, gender, age, socio-economic, nutritional, and genetic is a subjective concept. We wanted to determine the facial morphology, golden ratio, and classify the face shape, in Turkish healthy adults. METHODSThis is a descriptive study conducted among two hundred twenty-eight (139 females; 89 males) subjects aged between 18 and 25 years. Physiognomic facial height, the width of face, face golden ratio, morphological facial height, facial index were measured. Based on the face index, the face shape was classified as hypereuryprosopic, euryprosopic, mesoprosopic, leptoprosopic, and hyperleptoprosopic. Also, the face shape was determined according to the golden ratio. Statistical analysis was done by SPSS Ver. 22. Chi-Square Test was used to determine the differences between gender and face measurements. A p value of <0.05 value was considered as significant.RESULTSOut of 228 subjects, face shape according to golden ratio was normal in 11 female subjects, short in 128 female subjects. Also, in males, the same parameter was normal in 10 subjects, short in 72, and long in 7 subjects. On the other hand, significant differences were found between the genders. Hypereuroprosopic face type was the least observed in males but not in females.CONCLUSİONSThe facial shape data may be valuable for evaluating various disorders and variations for plastic surgeons and orthodontists and other clinicians

The aim of this study was to determine the normal values of brain ventricles and indices in healthy subjects in our population using magnetic resonance imaging (MRI) and to reveal sex and age related differences. The MRI of two hundred-sixty-five healthy individuals aged between eighteen and eighty-seven years were examined and the midsagittal and axial images were used for measurements. The measurements were performed from MRI on a Workstation. The following mean values of brain ventricles and indices were observed; frontal horn width (FHW) (33.14 mm); third (3rd) ventricle width (TVW) (3.37 mm); fourth ventricle anteroposterior width (FVWAP) (9.93 mm); fourth ventricle transverse width (FVWT) (12.40 mm); and the maximum transverse inner diameter of the skull (TIDS) (128.75 mm) in females. The same dimensions were 34.85 mm, 3.91 mm, 10.26 mm, 12.81 mm, and 134.68 mm in males, respectively. There were statistically significantly differences in the frontal horn width, third (3rd) ventricle width, and the maximum transverse inner diameter of the skull values in between sexes. The mean values of Evans' index which obtanied with maximum width between the frontal horns of the lateral ventricles divided by the maximum transverse inner diameter of the skull were found as 0.280 ±0.172 in females; whereas the same dimensions were calculated 0.276±0.161 in males. These values were lower in healthy male subjects than females, however; there were no found significantly difference between groups. Present findings obtained from MRI are necessary anatomical baseline data for interpreting pathological changes, planning surgery, and determining presence and progress of some neurological diseases.
