Nasorbital mucormycosis

Last reviewed: 23.04.2024
Naso-orbital mucormycosis is a rare opportunistic infection caused by fungi of the family Mucoruceae, usually affecting patients with diabetic ketoacidosis or with suppression of immunity. This aggressive and fatal infection is characterized by the defeat of the upper respiratory tract through inhalation of spores. Hence the defeat passes to the adjacent sinuses, then into the orbit and the brain. The defeat of vessels in the form of occlusive vasculitis leads to ischemic infarctions of orbital tissues.
Nasorbital mucormycosis manifests itself gradually increasing edema of facial tissues and periorbital, diplopia and loss of vision.
[Symptoms of Nazorbital mucormycosis
- Ischemic infarctions and septic necrosis lead to the appearance of black scabs in the sky, hoans, nasal septum, skin and eyelids.
- Ophthalmoplegia.
- The slower development of cellulite orbit, than bacterial.
Complications are made up of occlusion of the vessels of the retina, multiple paralysis of the cranial nerves and occlusion of the cerebral vessels.
How to examine?
Treatment of Nazorbital mucormycosis
- Amphotericin intravenously.
- Daily sealing and irrigation of affected areas with amphotericin.
- Extensive excision of non-viable and necrotic tissues.
- Additional hyperbaric oxygenation may be useful.
- If possible, correction of metabolic disorders.
- In non-retractable cases, it may be necessary to expander the orbit.
