    • Abstract:
      Background: Mucormycosis is a fungal infection caused by the Mucorales order of fungi. This fungus is commonly found in soil and can cause disease in immunocompromised patients. On the other hand, Bell's palsy is an idiopathic condition that results in the sudden onset of unilateral facial muscle weakness, affecting the facial nerve.
      Case Presentation: A 51-year-old Persian housewife with a history of poorly controlled diabetes mellitus presented with a splitting headache that had been ongoing for 1 week and an inability to close her left eye or make facial expressions on the left side of her face. The patient's vital signs were normal, but physical examination revealed a yellow-grey scar on the left side of her hard palate and Bell's palsy on the left side. A neurological examination showed that she could move both eyes but could not close her left eye, move up her left eyebrow, or smile. Further investigations were performed, including laboratory tests, radiologic imaging, and functional endoscopic sinus surgery. The patient underwent three rounds of debridement for bony erosion in the medial and posterior walls of the left maxillary sinus and the hard palate. Pathological examination confirmed mucormycosis infection in the hard palate and mucosa.
      Conclusion: Fungal infection must be considered a potential diagnosis for immunocompromised adults who exhibit symptoms of Bell's palsy.
