Purpose: The aim of this study was to determine the frequency of anatomical parameters and their measurement as seen on normal posteroanterior (PA) chest radiographs in a Turkish population. Materials and Methods: We evaluated fifty normal PA chest radiographs of Turkish population adults. The frequency of anatomical parameters and their measurement with respect to the diaphragm was evaluated. Results: The frequency of anatomical parameters and their measurement with respect to the diaphragm is as follows: level (right side higher in 98%, left and right sides same level 2%), lobulation (88% absent, 12% present), eventration (98% absent, 2% present) and contour (90% smooth, 10% not smooth); level of hilum (right and left sides same level 52%, left side higher 36%, right side higher 12%); number of pairs of ribs (twelve 96%, unable to determine 4%); number of ribs superposing the lung parenchyma (seven 2%, eight 4%, nine 24%, ten 70%); distance from the lateral margin of the vertebral body to the aorta (16.44 +/- 4.35 mm); angle between the vertebral body and the aorticopulmonary line (16.04 +/- 3.110); the carina angle (58.46 +/- 11.130) and the cardiothoracic ratio (38.75 +/- 4.27). Conclusion: The data presented in this study may be useful in understanding normal thoracic structures. A knowledge of the normal anatomy as well as variations are significant for physicians in the assessment of chest radiographs.

(2018) Ozsahin, Esin; Boyan, Neslihan; Kizilkanat, Emine; Soames, Roger W.; Oguz, Ozkan
The current study was undertaken to assess the incidence of different types of suprascapular notch, acromion dimensions and the lower and upper scapular angles. The suprascapular notch and variations of the acromion are clinically important in suprascapular nerve compression and subacromial impingement. Measurements were taken from 73 Anatolian dry scapulae of unknown age or sex. The suprascapuar notch was classified according to that of Rengachary et al. (1979). Its width and depth, the distance between supraglenoid tubercle and the deepest point of notch, as well as the upper and lower scapular angles were also determine measured. The type of acromion was assessed according to shape (type I (cobra), type II (square), type III (intermediate)) and tilt (type I (flat), type II (curve). Acromion length and the distance between acromion and coracoid process were also measured. The frequency of different types of suprascapular notch were type I (28.8 %), type II (23.3 %), type III (13.7 %), type IV (20.5 %), type V (2.7 %), type VI (5.5 %)and absence (5.5 %). Acromion type were type I (45.5 %), type II (7.5 %) and type III (47.0 %), acromion tilt type I (15.2 %), and type II (84.8 %). An understanding of the association between the anatomical structures of the scapula and morphometric measurements is clinically important.

(2016) Ozsahin, Esin; Kizilkanat, Emine; Boyan, Neslihan; Soames, Roger; Oguz, Ozkan
The aim of this study was to determine the types of face shape in the Turkish population. Knowledge on face shape is important in anthropology and for planning medical procedures such as in aesthetic, maxillofacial and orthodontic surgery. The study group consisted of 1003 healthy subjects (470 male, 533 female) aged 18-68 years. Mean height, weight and body mass index (BMI) were 1.74 m, 78.65 Kg, 25.80 +/- 3.50 kg/m(2) and 1.62 m, 60.55 kg, 22.87 +/- 3.49 kg/m(2) in males and females, respectively. Face length (FL; the distance from nasion to gnathion) and face width (FW; bizygomatic breadth) were measured, from which a Prosopic Index (PI) was determined using the following formula: (PI=FL/FW x 100). The types of face shape were classified according to Banister's classification Type I (hypereuryprosopic), Type II (euryprosopic), Type III (mesoprosopic), Type IV (leptoprosopic), Type V (hyperleptoprosopic) in both males and females. PI was 84.31 (FL: 12.07 cm; FW: 14.34 cm) in males and 85.25 (FL: 11.30 cm; FW: 13.28 cm) in females. In males and females Type I face shape was observed in 18.1 % and 15.6 %; Type II in 35.3 % and 34.3 %; Type III in 33.2 % and 34.3 %; Type IV in 8.7 % and 11.8 %; and Type V in 4.7 % and 3.9 %, respectively. The determination of types of face shape as presented in this study may be useful for aesthetic surgical procedures as well as medical and anthropological investigations.

(2023) Polat, Sema; Isik, Emir Ibrahim; Vuralli, Duygu; Oksuzler, Mahmut; Oksuzler, Fatma Yasemin; Ozsahin, Esin; Goker, Pinar
Pelvis contributes to both human locomotion and obstetrics, and normal vaginal delivery is associated with a spacious inlet, a large interspinosus diameter. This paper aimed to measure crucial diameters of pelvic ring, and to determine both the prevalence of pelvic types, and labor types including normal vaginal delivery or caesarean section in Turkish healthy females. Additionally, it was aimed to evaluate presence of relationship between pelvic types and pelvic diameters. Labor shape of subjects was obtained from hospital records. This retrospective study was carried out on 165 healthy subjects aged between 18 and 45 years. Anteroposterior diameter of the pelvic inlet (APDI), anteroposterior diameter of the pelvic outlet, sacrum length (SL), sacrum depth, conjugata vera, obstetrical conjugate, the diagonal conjugate, diameter transversa, diameter bispinous, intertuberous diameter were measured. From these measurements, brim index was calculated and decided to gynecoid, anthropoid and platypelloid type. Also, the andoid type was calculated to the ratio of posterior sagittal diameter of the inlet to conjugata obstetrica. 50.91 % of participants has gynecoid type pelvis, followed by 24.85 % anthropoid type, 14.55 % platypelloid, and 9.70 % android type pelvis. There was a significant difference in APDI, SL, SD, Conjugata vera, Conjugata obstetrica, Conjugata diagonalis, Conjugata transversa, diameter bispinous, diameter intertubercularis and Brim index measurements according to pelvic types. the first degree of narrowing (conjugata vera from 11 to 9) was found in 18 pelvises and 12 pelvises with the pathological degree of narrowing bellonged to the platypelloid type followed by android type pelvis with 6 pelvices. The android type pelvis is not appropriate for natural labor and a good assessment of birth canal can reduce the labor risks. Also, only 7 females who delivered with cesarean have gynecoid type pelvic type. The APDI and SL were significantly lower in subjects having pathological narrowing according to conjugata obstetrica values.
Extracranial Landmarks for Surgical Skull Base Approaches
(2021) Ozsahin, Esin
Surgical operations regarding to skull base are challenging and reliable anatomical landmarks are required. There is a lack of knowledge on anatomical variations in this region. The aim of this study was to determine the safe extracranial landmarks for surgical approach to the skull base. In this study, 23 adult dry skulls were evaluated: the age and sex of the specimens were unknown. All measurements were taken from external surface of inferior aspect of the skull by using digital calipers accurate to 0.01 mm. In right and left sides; the distances between the external acoustic meatus (EAM) and the following anatomical landmarks were measured: articular tubercle (AT); anterior margin of squamous suture (ASS); superior margin of squamous suture (SSS); posterior margin of squamous suture (PSS); end point of styloid process (SP); midpoints of pterygomaxillary fissure (PMF); foramen ovale (FO); foramen spinosum (FS); and of carotid canal (CC).The distances of the external acoustic meatus to the anatomical structures on the right and left sides were: EAM-SP; 24.24±3.19 mm, 23.16±3.17 mm; EAM-PMF; 46.56±4.51mm, 46.25±3.96 mm; EAM-FO; 27.57±2.87 mm, 28.70±2.85 mm; EAM-FS; 22.53±3.19 mm, 22.72±3.47 mm; EAM-CC; 17.35±3.56 mm, 17.19±3.39 mm; EAM-AT; 19.31±3.79 mm, 18.95±3.42 mm; EAM-ASS; 43.14±4.80 mm, 46.82±4.61 mm; EAM-SSS; 49.17±4.74 mm, 48.83±3.34 mm and EAM-PSS; 36.15±4.24 mm, 35.39±4.25 mm, respectively. We think that the findings obtained from this study related to external acoustic meatus can be an important reference for surgical anatomy and surgical procedures in skull base.

(2016) Boyan, Neslihan; Ozsahin, Esin; Kizilkanat, Emine; Soames, Roger; Oguz, Ozkan
Anatomical variations in terms of ligamentous attachments, articulations and bony morphology are common in the subtalar region. The shape of the articular facets of the talus and calcaneus and their relationship to each other are important for joint function and surgical procedures. In this study an assessment of the morphology of the articular facets of the talus and calcaneus, in an Anatolian population, was undertaken. 49 tali and 57 calcanei from Anatolian adults of unknown gender were examined. The types of articular facets on the talus and calcaneus were determined using the following classification: Type A1, the distance between the anterior and middle facets was less than 2 mm; Type A2, the distance between the anterior and middle facets was 2-5 mm; Type A3, the distance between the anterior and middle facets was more than 5 mm; Type A4, there was only one articular facet; Type B1, the separation between the anterior and middle facets was not complete; Type B2, separation of the anterior and middle facets was present; Type C, no separation between the anterior, middle and posterior facets was present, i.e. there was one articular facet. In addition, the anteroposterior length and width of the talus and calcaneus, together with the width, length and depth of sulcus tali and sulcus calcanei were determined. Left and right tali, respectively, displayed the folowing types of articular facet: A1, 0 %, 0 %; A2, 0 %, 3,4 %; A3, 0 %, 0 %; A4, 0 %, 0 %; B1, 60 %, 51,8 %; and B2, 40 %, 44.8 %. Articular facets on left and right calcanei, respectively, were: A1, 10 %, 7.4 %; A2, 10 %, 14.8 %; A3, 16.7 %, 11.1 %; A4, 3.3 %, 3.7 %; B1, 30 %, 22.2 %; B2, 30 %, 40.8 %. The length and width of left and right tali were 50.5 +/- 3.81 mm and 39.5 +/- 2.97 mm, and 53.1 +/- 4.38 mm and 39.3 +/- 3.66 mm, respectively. The width, length and depth of left and right sulcus tali were: 5.2 +/- 1.09 mm, 21.7 +/- 2.73 mm and 5.7 +/- 0.84 mm, and 6.1 +/- 2.05 mm, 21.1 +/- 3.66 mm and 5.7 +/- 1.52 mm, respectively. For left and right calcanei length and width were; 76.1 +/- 5.44 mm 44.0 +/- 3.97 mm, and 75.7 +/- 6.76 mm and 45.9 +/- 4.21 mm, respectively. The width, length and depth of left and right sulcus calcanei were: 6.4 +/- 1.19 mm, 31.9 +/- 2.76 mm and 4.0 +/- 0.81 mm, and 5.5 +/- 1.00 mm, 32.4 +/- 3.23 mm and 4.4 +/- 1.05 mm, respectively. The articular facets on both the talus and calcaneus in the Anatolian population studied was predominantly type B. This observations is similar to previous reports conducted in America, India and Africa, but differ from those undertaken in Europe. A knowledge of variations of the articular facets of the talus and calcaneus provides a valuable road map for orthopaedic surgeons, as well as others involved in foot rehabilitation.

(2023) Polat, Sema; Oksuzler, Mahmut; Oksuzler, Fatma Yasemin; Ozsahin, Esin; Goker, Pinar
The trachea is a tubular organ lying between larynx and lungs containing smooth muscle, membranes, and cartilage. This paper evaluated the dimessions of the trachea and main bronchi morphometry in healthy adults using Computed Tomography. This retrospective observational study was performed with 170 healthy adult subjects (89 females, 52.35 %; 81 males,47.65 %). The length of the trachea, the anteroposterior and transverse diameter of the trachea and the right and left main bronchi were measured. From these measurements, the trachea shape were calculated and four types of trachea were identified as circular, oval, horseshoe-shaped, and rectangular. All measurements were significantly higher in males than females (excluding tracheal bifurcation angle). According to the value obtained by dividing the anteroposterior by the width of the trachea, tracheal shapes are considered; the circular shape was seen 104 subjects (61.2 %), followed by oval type (34 subjects), horseshoe type (24 subjects) and rectangular type.(8 subjects). Also, the most frequently seen was circular type in both females and males. Hovewer, there was no significant difference between sex in terms of trachea shape. Additionally, a striking finding was that trachea morphometry and morphology showed the significance according to age dependent changes. Trachea measurements were affected several reasons such as used methods, age, sex, or race. This study has many clinical importance as it may reduce the risk of accidental damage to these area by clinicians such as cardiothoracic surgeons, anesthetist, or radiologist.
