Prosthetic Management of a Maxillofacial Defect Post-Mucormycosis: A Case Report

Area of Science:

• Oral and Maxillofacial Surgery
• Infectious Diseases
• Prosthodontics

Background:

• Mucormycosis is a rare, aggressive fungal infection.
• Rhinocerebral mucormycosis can cause extensive tissue necrosis, including maxillary defects.
• Immunocompromised individuals are primarily affected.

Purpose of the Study:

• To report the prosthetic rehabilitation of a patient with a severe maxillary defect secondary to rhinocerebral mucormycosis.
• To evaluate the effectiveness of reconstructive interventions in restoring function and aesthetics.

Main Methods:

• A 68-year-old male with a history of COVID-19 presented with rhinocerebral mucormycosis.
• Surgical debridement included left hemimaxillectomy and left eye enucleation.
• Fabrication of a maxillary obturator and an orbital prosthesis with magnetic attachments.

Main Results:

• The patient adapted well to the prostheses, regaining speech and swallowing functions.
• The maxillary obturator restored oral and nasal cavity separation.
• The orbital prosthesis with magnetic attachments provided enhanced retention and comfort.
• Significant improvements in function and aesthetics were reported at the 2-year follow-up.

Conclusions:

• Prosthetic rehabilitation is effective in managing severe maxillary defects caused by rhinocerebral mucormycosis.
• Maxillary obturators and orbital prostheses can restore essential functions and improve quality of life.
• Magnetic attachments offer a viable solution for prosthesis retention and patient comfort.
