this is a report of a case with unilateral cavernous sinus thrombosis due to ipsilateral ethmoid sinusitis. a 10 year old female was admitted in our hospital with severe headache, purulent postnasal discharge, right eye proptosis and third cranial nerve palsy in the same eye. she had history of viral upper respiratory tract infection and then acute otitis media which did not improve with routin...

BACKGROUND Anterior and posterior ethmoid arteries supply the paranasal sinuses, septum, and lateral nasal wall. Precise identification of these arteries is important during anterior skull base procedures, endoscopic sinus surgery, and ligation of ethmoid arteries for epistaxis refractory to standard treatment. There is controversy in the literature regarding the prevalence of supernumerary eth...

OBJECTIVES Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior eth...

Ethmoid adenocarcinoma is the most frequent ethmoid tumor. To date, only a single case of spinal cord compression resulting from ethmoid adenocarcinoma has been reported. The current case study presents a recent case of vertebroepidural metastasis of an ethmoid adenocarcinoma leading to spinal cord compression. Modern imaging studies, including magnetic resonance imaging (MRI) and 18 fludeoxygl...

Progressive ethmoid hematoma is a widely recognized disease process in horses but has an incompletely understood etiopathogenesis. The mass lesion of progressive ethmoid hematoma expands by repeated hemorrhage and is usually extensive when a diagnosis is made. Diagnostic techniques (e.g., upper airway endoscopy, radiography, computed tomography) aid in determining the extent of a progressive et...

Globe perforation was detected in an 18-year-old male patient having total vision loss in the left eye following a car accident. The middle meatus could not be evaluated by sinonasal endoscopy because of edema. Computed tomography showed a foreign body in the left posterior ethmoid sinus, with a trajectory coursing from the globe to the lamina papyracea, and the posterior ethmoid sinus. Endosco...

Introduction The anterior ethmoidal artery (AEA) is one of the main arteries that supply both the nasal mucosa and the ethmoid sinuses. The AEA shows variability regarding its distance from adjacent structures. Several studies have developed techniques to identify the AEA. Objective This study aimed to compare the measurements from the AEA to the ethmoid bulla and to the frontal beak by using c...
