Orbital Myiasis Secondary to Neglected Maxillary Sinus Squamous Cell Carcinoma in an 85-Year-Old Woman: A Case Report

Orbital myiasis is a rare and destructive infestation caused by fly larvae, often associated with chronic ulcerative lesions or malignancies in the head and neck region.

We report the case of an 85-year-old female with stage IVB maxillary sinus squamous cell carcinoma who developed severe orbital myiasis. The patient presented with a large ulcerative facial lesion involving the lower eyelid and maxillary region, with multiple live larvae visible within necrotic tissue. Emergent removal of larvae, wound debridement, daily antiseptic irrigation, systemic antibiotics, and palliative care were performed.

Orbital myiasis in the setting of advanced head and neck malignancy is uncommon but can rapidly progress and significantly increase morbidity. Prompt recognition and early intervention are essential.
