Analog and Digital Protocols for Functional Prosthetic Rehabilitation of Post-COVID-19 Rhino-Orbito Cerebral Mucormycosis Maxillofacial Defects: A Case Series

Abstract

The current study aims to present our clinical observations and experience gathered during the diagnosis, clinical presentation, medical/surgical treatment, and functional prosthetic rehabilitation of cases of rhino-orbital/cerebral Mucormycosis patients. Mucormycosis is an aggressive, life-threatening invasive fungal infection that occurs in people who are immune-compromised. The rise of ROCM during the second wave of the COVID-19 pandemic in India suggests a more effective association between Mucormycosis and the SARS-CoV-2 delta variant. The treatment strategy for Mucormycosis is an early diagnosis which is critical for a successful outcome. The initial step is to reduce or remove underlying risk factors followed by surgical excision and debridement of the afflicted tissues supplemented with antifungal medication. The first-line antifungal treatment is Liposomal Amphotericin B. Postsurgical resection defects are rehabilitated by either removable partial prosthesis (obturators) or by fixed zygomatic implant/patient-specific implant supported prosthesis. Management of ROCM requires a multidisciplinary approach. This case series highlights detailed medical, surgical, and functional prosthetic management modalities adopted by our team in managing such a dreaded disease which may be used as a tool for the formulation of standardized prevention and management/treatment/rehabilitation protocols in the future so that disease morbidity and mortality be reduced and an endemic outbreak could be averted.
