Objective To study the possible association between invasive fungal sinusitis (mucormycosis) and coronavirus disease. Methods A prospective observational study was conducted at a tertiary care centre over four months, involving all patients with mucormycosis of the paranasal sinuses suffering from or having a history of coronavirus disease infection. Results Twenty-three patients presented with mucormycosis, all had an association with coronavirus disease 2019. The ethmoids (100 per cent) were the most common sinuses affected. Intra-orbital extension was seen in 43.47 per cent of cases, while intracranial extension was only seen in 8.69 per cent. Diabetes mellitus was present in 21 of 23 cases, and was uncontrolled in 12 cases. All patients had a history of steroid use during their coronavirus treatment. Conclusion New manifestations of coronavirus disease 2019 are appearing over time. The association between coronavirus and mucormycosis of the paranasal sinuses must be given serious consideration. Uncontrolled diabetes and over-zealous use of steroids are two main factors aggravating the illness, and both of these must be properly checked.

To the best of our knowledge, this is the first large sample study of cochlear length in population of this part of the world. A smaller cochlear length in this part of the world as compared to the Caucasian cochlear duct is a significant finding in understanding of the cochlear anatomy and physiology. It would also have great implications on the insertion depth in cochlear implantation.

Objective To study unusual presentations of coronavirus-associated mucormycosis that are rarely seen in sinonasal mucormycosis cases. Method The data of 400 rhino-orbito-cerebral mucormycosis patients admitted to Sawai Man Singh Hospital, Jaipur, from May 2021 to June 2021, were retrospectively collected. The diagnosis of mucormycosis was made by histological examination of biopsy samples. Results Out of 400 patients, 62 had symptoms other than common symptoms of rhino-orbito-cerebral mucormycosis. Thirty-four patients had facial palsy, 19 complained of gum ulcers, 6 developed a cheek abscess, 2 complained of maggots in the nose along with common rhino-orbito-cerebral mucormycosis symptoms, and 1 had a cerebellar infarct. Conclusion Mucormycosis is a disease with various presentations, and coronavirus-associated mucormycosis has added unusual presentations to the existing list of manifestations of rhino-orbito-cerebral mucormycosis. In this coronavirus disease era, mucormycosis should always be considered as a diagnosis in patients with these unusual presentations.
