Surgical Rehabilitation of a Continuous Orbital and Maxillary Defect from Rhino-Orbital Mucormycosis Utilising Digital Technology - A Case Report.

Rationale:COVID-19 has led to a resurgence in cases of mucormycosis, especially the rhino-orbital form affecting the oral cavity, nasal, orbital and cerebral regions. Patient Concerns:The surgical treatment in this patient led to the exenteration of orbital contents and segmental maxillectomy of the affected side leading to facial disfigurement and inability to masticate. Diagnosis:A combined mucormycosis-associated oro-orbital defect was present leading to a communication between oral and orbital cavities. Treatment:Rehabilitation utilising digital technology for removable prosthesis was planned for the combined orbital and oral defect. Outcomes:The independent intraoral and orbital prosthesis reduced the mobility of the orbital prosthesis while performing functional movements. The advancements in digital technology led to the convenient and resilient fabrication of prostheses for large facial defects. Take-away Lessons:The prosthetic rehabilitation of a continuous orbital and oral defect with a hybrid of both digital and conventional means provided an aesthetic, feasible and financially sound solution to the patient.
