Background:
Osteonecrosis in mucormycosis is a rare phenomenon and has been reported usually following trauma or in immunocompromised individuals. Osteonecrosis of skull as a complication of mucormycosis is a rare presentation, which makes the study ever so rare and interesting.
Methods:
Within 6 months, a total of 114 patients presented with mucormycosis as COVID-19 sequel, 60 of whom underwent form of endoscopic sinus debridement. Six of these 60 patients presented with frontal bone osteonecrosis and were included in the study. All 6 patients presented within a time period of 2-4 months' post FESS.
Results:
One of the 6 patients succumbed to her illness. Another patient presented with local recurrence after 3 months, for which she underwent resurgery and debridement. The other 4 patients showed gradual recovery and are without symptoms or radiologic progression at 6-month follow-up.
Conclusions:
Osteonecrosis in mucormycosis is a rare phenomenon, and the 2 entities have rarely been reported together. The disease usually limits itself to the frontal bone only, and pathogenesis for spread is due to a vicious cycle of infection and ischemia. Prompt diagnosis via imaging, aggressive surgical debridement with a good antifungal cover, good patient compliance, and regular follow-up form the mainstay of treatment.
