Abstract
A very uncommon instance of facial nerve palsy involving isolated temporal bone with associated uncontrolled diabetes mellitus has been noticed. A 53-year-old diabetic male presented himself with facial asymmetry, ear pain, and discharge in the right ear of one-month duration. Clinical examination revealed grade IV [House-Brackmann] right sided facial palsy, and otoscopy of small central perforation. Clinically acute otitis media with facial palsy diagnosis was made. There was minimal response to medical treatment. As per CT scan and audiometry findings, patient was subjected for exploratory mastoidectomy showing pale granulation tissue involving geniculate ganglion of facial nerve. The histopathology was suggestive of mucormycosis, an unusual presentation in middle ear. The patient was treated with injectable Amphotericin B. This case highlights a rare cause of isolated facial palsy and physicians should be aware of such atypical clinical presentation.
Highlights
The purpose of presenting this case report is to highlight the rare manifestation of mucormycosis causing facial nerve palsy
Factors associated with an increased risk of mucormycosis include diabetes mellitus, immunosuppression, metabolic acidosis and administration of high dose systemic corticosteroids in solid organs
We reviewed published reports of mucormycosis causing isolated facial paralysis and found only two cases
Summary
The purpose of presenting this case report is to highlight the rare manifestation of mucormycosis causing facial nerve palsy. Many cases of mucormycosis [1]-[4] causing facial palsy have been reported in medical journals published in English literature. Mucormycosis is the term used to describe fungal infections caused by fungi in the order Mucorales, and species in the Mucor, genera rhizopus, absidia and cunninghamella are most often implicated [5]. This disease is often characterized by hyphae. (2015) A Rare Case of Facial Palsy Due to Mucormycosis. The temporal bone may be affected by mucormycosis
