OBJECTIVE We evaluated the extent of asymmetry evident in paranasal sinus computed tomography (CT) scans of Turkish patients without sinusitis in the ethmoid roof. Our data contribute to the body of knowledge on the subject. MATERIALS AND METHODS We retrospectively studied multiplanar reformatted CT images of the paranasal sinus (1-mm sections) from 110 patients (50 male, 60 female). Ethmoid ...

Cavernous sinus thrombosis is one of the most severe infections face, orbit, ear, paranasal sinuses and oral cavity. The studyaims to analyse clinical cases carotid-cavernous in patients with complications COVID 19. An analysis 2 clinicalcases a diagnosis cavernous presence 19 was carried out. General ophthalmic research methods (visometry, external examination, study pupillary reactions, ophth...

INTRODUCTION Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. CASE PRESENTATION We described a lateral frontal sinus mucocele w...

Introduction. Complications can occur as a consequence of both acute and chronic sinusitis. Most frequently complications are caused by acute ethmoiditis or frontal sinusitis. The complications of paranasal sinusitis are divided into intraorbital, intracranial and osteomyelitis. The children with complications of paranasal sinusitis require hospitalization, treatment with combined intravenous a...

The sinus sphenoidalis is the paranasal sinus most centrally located in the skull base and known to vary extremely in dimensions. A very large volume of the sinus visible on skull radiographs is called sinus 'hyperaeration'. This finding has been described many times in the literature, but is generally rare. The term 'pneumosinus dilatans' is synonymously used to address an unexpectedly large p...

To investigate the claim that the primate paranasal sinuses possess not a functional but a structural role associated with the skull architecture (Blaney, 1990), the relationship between the maxillary sinus and the skull architecture was studied ontogenetically in 30 skulls of male and female Japanese macaques (Macaca fuscata). Coronal CT scan series and computerised 3-dimensional images served...

Improvements in functional endoscopic sinus surgery (FESS) and computed tomography (CT) have concurrently increased interest in the anatomy of the paranasal region. Common anatomical variations are not rare in patients with chronic paranasal sinusitis. The aim of this retrospective study was to analyze the incidence of anatomic variations of the lateral nasal wall in a series of 200 patients wi...
