ABSTRACT
SUMMARY: The structure formed by the arteries, which is of great importance in the irrigation of the brain, is called the cerebral arterial circle (Polygon of Willis). Since the cerebral arterial circle provides brain nutrition, vascularabnormalities in this region are highly relevant. Therefore, the aim of our study was to examine the variations of the cerebral arterial circle in cadavers of Turkish individuals. In our study, 32 human cadavers obtained from three different universities were retrospectively examined. Brain tissue obtained from cadavers by craniotomy was kept in 20 % formaldehyde solution for an average of 10 days for fixation. Cerebral arterial circle diagrams were determined in all cadavers by staining and photographs were taken. As a result of the brain examinations, a variation of the cerebral arterial circle was detected in 24/32 brains. Vascular variations have an important place in congenital variations. For this reason, we believe that our brain study will contribute to clinical studies on this topic by investigating variations of the cerebral arterial circle.
La estructura formada por las arterias que tiene una gran importancia en la irrigación del cerebro se denomina círculo arterial cerebral (Polígono de Willis). Dado que el círculo arterial cerebral proporciona la irrigación cerebral, las anomalías vasculares en esta región son muy relevantes. Por lo tanto, el objetivo de nuestro estudio fue examinar las variaciones del círculo arterial cerebral en cadáveres de individuos turcos. En nuestro estudio, se examinaron retrospectivamente 32 cadáveres humanos obtenidos de tres universidades diferentes. El tejido cerebral de los cadáveres fue obtenido por craneotomía y se mantuvo en solución de formaldehído al 20 %, durante 10 días en promedio para su fijación. Se determinaron los diagramas de círculo arterial cerebral en todos los cadáveres mediante coloración y se tomaron fotografías. Como resultado de los exámenes, se detectó una variación del círculo arterial cerebral en 24/32 de los cerebros. Las variaciones vasculares tienen un lugar importante en las variaciones congénitas. Por esta razón, creemos que nuestro estudio contribuirá a estudios clínicos sobre el tema al pesquisar las variaciones del círculo arterial cerebral.

SUMMARY: Several studies have shown beneficial effects of platelet-rich plasma. However, there are very few studies investigating the effectiveness of PRP in the neck region. We aimed to assess the efficacy of PRP injection for neck rejuvenation in females aged 40-55. Fifty-two female consecutive participants had PRP injected and roller applied in three sessions at 3-week intervals. Evaluations were blindly performed by comparing the improvements from the pre- to post-application assessments of anatomical measurements of the neck area based on before and after photography of the participants by two anatomists and three medical aesthetic doctors. The Fitzpatrick Skin Scale, Fitzpatrick Goldman Scale, Wrinkle Assessment Scale (Dedo classification system) and patient satisfaction scale were used for assessment. Additionally, skin stiffness and elasticity, cervicomental angle and jawline angle measurements were performed to analyze anatomical changes in the neck area. The study enrolled 52 volunteers with a mean age of 48.60±5.35 years, mean body weight of 63.21±8.43 kg and mean height of 163.25±4.56 cm. Significant differences were found in the elasticity, jawline angle, cervicomental angle, wrinkling, elasticity G and patient satisfaction scores before and after the treatment. When the results of anatomical parameters and scales are compared, it was revealed that PRP is effective in neck rejuvenation.
RESUMEN: Varios investigaciones han demostrado los efectos beneficiosos del plasma rico en plaquetas. Sin embargo, existen muy pocos estudios que investiguen la efectividad del PRP en la región del cuello. Nuestro objetivo fue evaluar la eficacia de la inyección de PRP para el rejuvenecimiento del cuello en mujeres de 40 a 55 años. A cincuenta y dos mujeres participantes consecutivas se les inyectó PRP y se les aplicó rodillo en tres sesiones a intervalos de 3 semanas. Las evaluaciones se realizaron a ciegas comparando las mejoras de las evaluaciones previas y posteriores a la aplicación de las medidas anatómicas del área del cuello basadas en fotografías de antes y después de los participantes realizadas por dos anatomistas y tres médicos especialistas en cirugía estética. Para la evaluación se utilizaron la escala de piel de Fitzpatrick, la escala de Fitzpatrick Goldman, la escala de evaluación de arrugas (sistema de clasificación Dedo) y la escala de satisfacción del paciente. Además, se realizaron mediciones de rigidez y elasticidad de la piel, ángulo cervicomentoniano y ángulo de la línea de la mandíbula, para analizar los cambios anatómicos en el área del cuello. El estudio inscribió a 52 voluntarios con una edad media de 48,60±5,35 años, un peso corporal medio de 63,21±8,43 kg y una altura media de 163,25±4,56 cm. Se encontraron diferencias significativas en las puntuaciones de elasticidad, ángulo mandibular, ángulo cervicomentoniano, arrugas, elasticidad G y satisfacción del paciente antes y después del tratamiento. Cuando se compararon los resultados de los parámetros anatómicos y las escalas, se reveló que el PRP es eficaz en el rejuvenecimiento del cuello.

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.

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
ABSTRACT
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.
El objetivo de este estudio fue determinar los valores normales de los ventrículos e índices cerebrales en sujetos sanos en nuestra población mediante el uso de imágenes de resonancia magnética (RM) y revelar las diferencias relacionadas con el sexo y la edad. Se examinó la resonancia magnética de 265 individuos sanos de entre 18 y 87 años, y se utilizaron las imágenes en sentido medio y sagital para las mediciones. Las mediciones se realizaron a partir de IRM en una estación de trabajo. Se observaron los siguientes valores medios de ventrículos e índices cerebrales: longitud del asta frontal (FHW) (33,14 mm); longitud del tercer ventrículo (TVW) (3,37 mm); longitud anteroposterior del cuarto ventrículo (FVWAP) (9,93 mm); longitud transversal del cuarto ventrículo (FVWT) (12,40 mm); y el diámetro transversal máximo del cráneo (SID) (128,75 mm) en las hembras. Las mismas dimensiones fueron 34,85 mm, 3,91 mm, 10,26 mm, 12,81 mm y 134,68 mm en machos, respectivamente. Hubo diferencias estadísticamente significativas en el ancho del asta frontal, el ancho del tercer ventrículo y el diámetro interno transversal máximo de los valores del cráneo entre los sexos. Los valores medios del índice de Evans que obtuvieron el ancho máximo entre los cuernos frontales de los ventrículos laterales dividido por el diámetro interno transversal máximo del cráneo se encontraron en 0,280 ± 0,172 en las mujeres; mientras que las mismas dimensiones se calcularon en hombres (0,276 ± 0,161). Sin embargo, estos valores fueron más bajos en hombres sanos que en mujeres; no se encontraron diferencias significativas entre los grupos. Los hallazgos actuales obtenidos de IRM son datos anatómicos de referencia necesarios para interpretar los cambios patológicos, planificar la cirugía y determinar la presencia y el progreso de algunas enfermedades neurológicas.
