Abstract Purpose:Paranasal sinus fungal infections often extend into the orbit, leading to visual dysfunction and poor prognosis. Early diagnosis and treatment with antifungal medication and surgical debridement are essential. While endoscopic sinus surgery is the standard approach, reports of orbital surgery via an anterior approach remain rare. We report a case in which the anterior approach resulted in favorable visual and systemic outcome.

Case:A 78-year-old man presented with left orbital pain, numbness, proptosis, eyelid swelling, and abduction limitation. MRI revealed a mass extending from the left maxillary sinus into the orbit. Although emergency sinus surgery and biopsy were performed at another hospital, the diagnosis remained unclear, and he was referred to our department.

Findings:Based on the clinical course, fungal sinusitis was suspected, and surgical debridement was planned. As the main lesion was located in the orbit, we performed an anterior approach through a subciliary incision combined with an endoscopic maxillary sinus approach. Intraoperative frozen sections revealed filamentous fungal aggregates with inflammatory infiltration. Postoperatively, voriconazole was administered, and both visual function and systemic condition improved.

Conclusion:In cases of fungal sinusitis extending into the orbit, surgical debridement with an anterior approach can be effective for improving visual and systemic outcomes. The anterior approach should be considered depending on lesion localization and ocular findings.
