"The Accessory Ethmoidal Canal Does Not Necessarily Contain an Arterial Structure".

The aim of our study is to describe the prevalence of the accessory ethmoidal artery in endonasal endoscopic cadaver dissections and to identify its intraorbital origin. : From 2018 to 2020, thirty-four nasal dissections were performed in seventeen adult cadaveric heads. We performed a complete ethmoidectomy to identify the ethmoidal canals.

Management of Patients With Graves Orbitopathy Using Endonasal Endoscopic Techniques.

Objective: The aim of the authors' study is to show their surgical results in orbital decompression using different endonasal endoscopic techniques. These approaches are according to the degree of proptosis and the presence or not of sight threatening.

Methods: The authors performed 31 orbital decompressions on 20 Graves orbitopathy patients.

Our experience in the management of orbital complications in acute rhinosinusitis.

Background And Objective: The spread of an infection from the paranasal sinuses is rare but severe. Between 4% and 20% of all rhinosinusitis can become complicated, orbital involvement being the most frequent (60-75%). Orbital complications are more common in children but more severe in adults.

Rhinocerebral mucormycosis in a 5-month heart transplant recipient.

Mucormycosis is an opportunistic acute fungal infection with a high mortality rate seen in immunocompromised patients. It is extremely rare in heart transplant recipients. Rhinocerebral mucormycosis (RM) is the most frequently observed presentation.

[Mucocele caused by postraumatic orbitary herniation].

Sinusal mucoceles are expansive lesions related to ostium sinus obstruction and treatment is surgical. We present a case of frontal mucocele secondary to ostium drainage obstruction due to herniated orbital content. This entailed difficulties for intranasal surgical resolution so a combined approach was used.
