Functional Rehabilitation - an Integral Component for Quality of Life in the Holistic Management of COVID-19 Associated Mucormycosis

To evaluate the quality of life in the post maxillectomy patients due to Coronavirus disease 2019 (COVID-19) associated Mucormycosis (CAM) following rehabilitation with obturators. The study also described the management and treatment outcomes of CAM patients. The study included 80 confirmed patients of CAM. The demographic profile, clinical presentations, predisposing and risk factors, and treatment outcomes were studied. Surgical and medical outcomes were expressed as percentages. After surgical debridement, 27 out of 80 patients were rehabilitated with obturators. The quality of life (QOL) of post debridement at 1 month (T1) vs. post 3 months (T2) of obturator use was measured using the oral health impact profile 14 (OHIP-14) scale. Maxillary sinus was involved in 98.75%, Ethmoid sinus in 51.25% and Sphenoid sinus in 26.25%. Surgical management involved Infrastructure maxillectomy in 56.25%, subtotal maxillectomy in 23.75%, and total maxillectomy with zygoma debridement in 20% of cases. Maxillary sinus debridement was done in 100%, Ethmoid sinus in 51.25%, and Sphenoid sinus in 26.25%. Medical management involved administration of intravenous Amphotericin B (total 3-5 g), and Posaconazole 300 mg OD for 3 months. The measured QOL using mean scores of each domain and the total score of OHIP-14 were lower at T2 (25.5 ± 6.809) compared to T1 (49.55 ± 9.822), (indicating better treatment outcomes) and were found to be statistically significant (P < 0.001). Early diagnosis, controlling risk factors, combined aggressive surgical and medical management reduces the morbidity and mortality of the patients. Early rehabilitation of the maxillectomy defects in CAM patients with temporary obturators mitigates deficient mastication and speech, thereby leading to improved function, aesthetics, and social well-being, and improving the overall QOL of these patients.
