A 56-year old woman presented with headaches and nasal congestion secondary to bilateral ethmoid osteomas and she made a full recovery following endoscopic resection. Paranasal osteomas are common, benign, encapsulated tumours that are often asymptomatic, but may present similarly to rhinosinusitis and occasionally cause complications depending on their anatomical location. Bilateral ethmoidal ...

One case of recurrent multifocal central giant cell granulomas (CGCG) is presented. Initially, the lesions presented concurrently in the maxilla and mandible with subsequent recurrence in the mandible. Now, two recurrences are seen in the maxillary sinus and ethmoid region. The literature regarding multifocal CGCG is reviewed.

INTRODUCTION To evaluate the efficacy and cost-effectiveness of the treatments used for controlling epistaxis, particularly compared with the surgical endoscopic ligation or cauterization of sphenopalatine (SP) and anterior ethmoid (AE) arteries, a intervention prospective-retrospective study is presented with the aim of assessing the feasibility of these surgical techniques as an alternative t...

This is a case report of aneurysmal bone cyst of the ethmoid. It is a benign process but with high capacity of local damage. Because of its resemblance with other expansive pathologies of the nasal cavity, it needs to be taken into account to ensure proper diagnosis and treatment.

We report the case of a 57-year-old male who presented with recurrent sinus infections and frequent nasal irrigation. He was found at nasal endoscopy to have multiple outgrowths along his ethmoid and maxillary sinuses. Computed tomography (CT) showed multiple bony exostoses along these sinuses. We report the imaging findings of exostoses associated with sinonasal irrigation.

Intranasal schwannomas are rare lesions, specially when they present with an intracranial extension. The fifth case in the medical literature of a naso-ethmoid schwannoma with extension into the anterior cranial fossa is presented. The magnetic resonance findings and the details of the combined intracranial / transfacial operative approach used are described. The possible origin and the clinica...
