It is so rare that an ENT (ear, nose, throat) doctor would not witness often  a case during their university time. So, the documentation available on the treatment of mucormycosis is limited. In fact, there used to be a couple of mucormycosis expert ENT surgeons for millions of people pre-pandemic. The sudden rise in mucormycosis cases has left a majority of the ENT doctors with no option but to accept mucormycosis cases, as the expert doctors were very much occupied and the patient would die if left untreated. The majority of the ENT doctors had to manage with minimal or no experience on mucormycosis, this has led to the recurrence of mucormycosis in the patients they treated. When a highly experienced doctor in mucormycosis treats a patient even he cannot guarantee that the individual is completely cured and will not have a relapse of mucormycosis; an inexperienced ENT surgeon will definitely have a high number of patients with recurrence due to which there were many recurrent cases of mucormycosis although it did not get the limelight of media or the Indian Government. History
The first case of mucormycosis was possibly one described by Friedrich Küchenmeister in 1855. Fürbringer first described the disease in the lungs in 1876. In 1884, Lichtheim established the development of the disease in rabbits and described two species; Mucor corymbifera and Mucor rhizopodiformis, later known as Lichtheimia and Rhizopus, respectively.
Diagnosis requires identifying the mold in the affected tissue by biopsy and confirming it with a fungal culture. Because the causative fungi occur all around, a culture alone is not decisive. Tests may also include culture and direct detection of the fungus in lung fluid, blood, serum, plasma and urine. Blood tests include a complete blood count to look specifically for neutropenia. Other blood tests include iron levels, blood glucose, bicarbonate, and electrolytes. Endoscopic examination of the nasal passages may be needed. Imaging
Imaging is often performed, such as CT scan of lungs and sinuses. Signs on chest CT scans, such as nodules, cavities, halo signs, pleural effusion and wedge-shaped shadows, showing invasion of blood vessels, may suggest a fungal infection, but do not confirm mucormycosis. A reverse halo sign in a person with a blood cancer and low neutrophil count, is highly suggestive of mucormycosis. CT scan images of mucormycosis can be useful to distinguish mucormycosis of the orbit and cellulitis of the orbit, but images may appear identical to those of aspergillosis. MRI may also be useful. Currently (when? ), MRI with gadolinium contrast is the investigation of choice in rhinoorbito cerebral mucormycosis. Culture and biopsy
To confirm the diagnosis, biopsy samples can be cultured. Culture from biopsy samples does not always give a result as the organism is very fragile. To precisely identify the species requires an expert. The appearance of the fungus under the microscope will determine the genus and species.
