The most studied recess of the sphenoid sinus seems to be the lateral one, which is highly variable. Less attention seems to be paid to the maxillary recess, extending anterior, inferior and lateral towards the maxillary sinus. Twenty patients were referred for CT of the paranasal sinuses (axial CT), during a 3-month period. After examining the morphology of the sphenoid sinuses, the authors found bilateral maxillary recesses in one patient. On either

The corona mortis (CMOR) represents the vascular connection of the obturator and external iliac systems. We aimed to evaluate by dissections the morphological possibilities of the CMOR and their individual combinations. For the study we used 20 human adult cadavers that were bilaterally dissected (40 hemipelvises), with evidences of the vascular elements at the level of the superior pubic branch in 32 (80%) of hemipelvises. The morphological patterns

The atrioventricular node (AVN) is the relay station for electrical impulses passing from the atria to the ventricles. The arterial resources of the AVN are functionally relevant and may be interfered by various surgical procedures which deal with the cardiac valves. Our study aim to bring detailed evidences on the arterial supply of the AVN. We dissected and microdissected 50 human adult hearts without any known history or evident cardiac pathology,

Collateral circles in neck own a particular importance in compensating the symptoms due to the unilateral occlusion of the common carotid artery. In addition, surgical procedures at the level of the thyroid gland and larynx raise the problem of a good knowledge of the arterial morphology at those levels. The present study was designed to investigate the possible morphologies of the thyroid arteries anastomoses. For the present study, 20 human adult

The present study was designed and performed on 20 human adult cadavers at the level of the retroperitoneal space in order to provide evidence of the paravertebral and prevertebral sympathetic ganglia. Only one specimen, male, presented two ganglia on the left side located on the first lumbar splanchnic nerve, one proximal and the other distal. The macroscopically detected swellings were drawn and certified as autonomic ganglia after performing silver

The aim of the present study was to anatomically evaluate in adults the neurovascular trigeminal relations in the cerebellopontine angle (CPA), from a morphological and topographical perspective and thus to improve, detail and debate the pre-existing information, with educational and surgical implications. For the present anatomical study we performed bilateral dissections on 20 human adult skull bases, in formalin-fixed cadavers, at the level of

As a rule the pterygopalatine ganglion (PPG) is considered to be a single structure of the parasympathetic nervous system, associated with the maxillary nerve in the pterygopalatine fossa (PPF). A few structural studies in humans are available in the indexed references. We designed the present study of the PPG in order to provide evidence of possible variations in morphological patterns of the PPG. We performed dissections of the PPF on 20 human
