Summary
Open surgical approaches are crucial for treating isolated frontal sinus mucormycosis, especially with extensive lateral extension. These methods ensure effective clearance when endoscopic procedures are insufficient.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Surgical Oncology
Background:
- Isolated frontal sinus mucormycosis is a rare fungal infection.
- Minimally invasive endoscopic techniques are increasingly preferred for sinus surgeries.
- However, open surgical approaches remain vital for extensive disease, particularly with lateral extension.
Purpose of the Study:
- To describe the clinical presentation and management of patients with isolated frontal sinus mucormycosis.
- To highlight the role of external surgical approaches in these specific cases.
Main Methods:
- Retrospective analysis of patient records.
- Review of associated clinical features and management strategies.
- Literature review on frontal sinus mucormycosis.
Main Results:
- Four patients with isolated frontal sinus mucormycosis were identified.
- All patients had a history of COVID-19 infection; 75% had diabetes mellitus.
- External approaches (Lynch Howarth, Bicoronal) were used due to extensive bony destruction and lateral extension.
Conclusions:
- Despite advances in endoscopic sinus surgery, open procedures are necessary for extensive frontal sinus mucormycosis with lateral spread.
- External approaches provide effective clearance in complex cases where endoscopic access is limited.
