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.
Radiological and Anatomical Evaluation of the Tracheal Morphology and Morphometry in Turkish Adults

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.
