Unlabelled: The purpose of the research was to define the frequency prevalence of the incorporation of sphenoid sinuses' septum / septa in the carotid canal of the adult population.
Materials And Methods: 296 computed tomography (CT) scans of the patients (147 females, 149 males), who did not present any pathology in the sphenoid sinuses, were evaluated in this retrospective analysis. Spiral CT scanner - Siemens Somatom Sensation 16 - was used to glean the medical images. Standard procedure applied in the option Siemens CARE Dose 4D. No contrast medium was administered. Multiplans reconstruction (MPR) tool was used in order to obtain frontal and sagittal planes from the transverse planes previously received.
Results: Bilateral incorporation of the main septum (MS) in the carotid canal was not present in any of the patients, whereas unilateral incorporation was noticed in 21.96% of the patients (17.68% females, 26.17% males). On the right side it occurred in 11.82% of cases (10.88% females, 12.75% males), and on the left side in 10.14% of cases (6.8% females, 13.42% males). Bilateral incorporation of the additional septum (AS) was found in 8.45% of the patients (4.08% females, 12.75% males), whereas unilateral incorporation was noted in 28.37% of the patients. It was seen on the right side in 11.82% of cases (12.93% females, 10.74% males), and on the left side in 16.55% cases (15.65% females, 17.45% males). The most common variant was the incorporation of only one of the septa (either the MS or the AS) in the wall of the carotid canal unilaterally. Such situation took place in 30.07% of the patients (29.25% females, 30.87% males). Incorporation of two septa on the same side was noticed in 4.39% of cases (4.08% females, 4.7% males), and incorporation of three septa in 0.34% of cases (0.7% males).
Conclusions: The anatomy of the paranasal sinuses is varied to a great extent, hence performing a CT scan is crucial before the scheduled surgery, as it may lessen the unforeseeable surgical complications, that may result from the high prevalence of variants in the sinuses.

The endoscopic transsphenoidal approach is a common approach used in skull base neurosurgery to reach the sellar region. One of the intraoperative risks of this approach is intraoperative bleeding out of the carotid artery. Gentle drilling can prevent carotid artery injury.

Introduction: Tuberculous otomastoiditis is a rare and serious infection that most often occurs in association with pulmonary involvement. It is easy to diagnose when the two pathologies are associated and isolated. We herein report the case of a patient initially hospitalized for Pseudomonas aeruginosa necrotising otitis externa (NOE), which delayed the diagnosis of tuberculous otomastoiditis.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Background: Transnasal endoscopic decompression of the optic nerve is increasingly gaining acceptance among ear, nose, and throat (ENT) surgeons, however neither strict indications for the procedure nor the precise extent of effective decompression have been firmly established to date. This study aimed to determine the distance between endoscopically visible, anatomical structures within the sphenoid sinus and the posterior (i.e.
