To assess the risk factors causative of ROCM post COVID-19. To determine the clinical manifestations, causative factors leading to surge in ROCM & factors contributing to poor prognosis in ROCM cases occurring in Western Rajasthan post COVID-19. In a Retrospective observational study, 56 post COVID-19 ROCM patients were analyzed from ‘May–June 2021’ at M.D.M. Hospital, Jodhpur. All patients after onset of disease were assessed as per selection criteria, included patients were examined for risk factors and clinical manifestations & then were statistically evaluated. Median age was 53 years with male to female ratio 2.7:1. Uncontrolled diabetes was noted in at least 85% patients. Steroid use was seen in 66%. Other major contributing factor to ROCM was the occupation; Out of 56 patients 69% were FARMERS.72% had no history of COVID-19 vaccination. Only 3% had no underlying disease. Overall mortality rate was 16% .2 determinants were associated with poor prognosis: higher HbA1c-Out of 7 cases of orbital exenteration, 6 (85%) had HbA1c > 12. 36% took immoderate amounts of Steam inhalation. Maxillary sinuses were the most involved sites (94%). Orbital involvement was seen in 33 and 12% were PL negative. Palatal involvement & intracranial involvement were seen in 14% and 7% respectively. Bilateral disease was seen in 28%. Uncontrolled DM & Humid working conditions came out to be the main predisposing factors for ROCM. Facial pain is considered to be the most common presenting complain. Maxillary sinus is the most involved site.
