The study was carried out on 50 human lower legs obtained during autopsies (KBET: 122.6120.315.2016). The anatomy of the joint was studied using classical anatomical description methods. Based also on literature we have reviewed the current knowledge on the inferior tibiofibular joint blood supply considering the important clinically aspect - vascular density. Authors of this paper postulate relatively low vascular density of the region described and potential worse condition for healing in case of injury or after surgical procedures performed. We also postulate that ligament screws should be positioned with special respect to time limit which enables proper healing of the syndesmosis.
The main goal of this study was to investigate possible residua of thymic tissue in 100 adult cadavers with no thoracic pathology known before, by dissection of standard locations of thymic tissue in perithyroid, periaortic, peritracheal and retrotracheal spaces, as well as areas located next to the course of phrenic, vagus and left recurrent laryngeal nerves. Thus obtained tissue samples were studied by two pathologists independently. The remnants of the thymic tissue were found in 61 out of 100 specimens studied. It means that residua of ectopic thymic tissue is common, which may have a huge impact on the results of treatment of many diseases i.e. myasthenia gravis in course of thymoma.
Autonomic nervous system of the pelvis is still poorly understood. Every year more and more pelvic procedures are carried out on patients suff ering from diff erent pelvic disorders what leads to numerous pelvic dysfunctions. Authors tried to review, starting from historical and clinical background, the most important reports on anatomy of the pelvic autonomic plexuses. We also pay attention to complete lack of knowledge of students of medicine on the autonomic nervous structures in the area studied. We present anatomical description of the pelvic plexuses including their visceral branches and anatomy of surrounding pelvic tissues which still remains unclear. More and more attention is paid to the topography of the plexuses specially because of new pain releasing techniques — neurolysies.
Purpose: The purpose of this research is to defi ne the total number of septa and the total number of antra in the sphenoid sinuses (created as a result of the presence of additional septa), as well as the relation between the number of the septa and their location in the adult population. Materials and Methods: The study was conducted as a retrospective analysis of the computed tomography (CT) scans of the paranasal sinuses of 296 patients (147 females and 149 males), who did not present any pathology in the sphenoid sinuses. The CT scans of the paranasal sinuses were done with the spiral CT scanner (Siemens Somatom Sensation 16) by using a standard procedure, in the option Siemens CARE Dose 4D, without using any contrast medium. After obtaining the transverse planes, the frontal and sagittal planes were created using secondary reconstruction tool (multiplans reconstruction — MPR). Results: The analysis of the obtained images in the transverse plane and secondary CT reconstructions has shown the presence of only one sphenoid septum (main septum — MS) in 21.96% of the patients, which divided the sphenoid sinus into two sphenoid antra. In 78.04% of the patients, there were more than one sphenoid septa present in the posterior part of the sphenoid sinuses, hence there were additional septa (AS) present. One AS was present in 22.97% of the patients. The most common variant — two AS — was found in 32.09% of the cases. The presence of more than two AS was found in the following number of patients: three AS in 9.8%, four AS in 7.09%, five AS in 1.69%, six AS in 3.04% and seven AS in 1.01%. Th e rarest variant was the presence of more than seven AS: eight AS in 0.34% and nine AS also in 0.34%. Th ere were no sphenoid sinuses that would have more than nine AS in the researched material. Conclusions: Due to the high incidence of the anatomical variants of the paranasal sinuses, a CT scan is recommended in all patients before a planned surgery in order to avoid the potential complications that might arise as a result of the complicated structure of the paranasal sinuses.
