Endoscopic management of rhinocerebral mucormycosis with topical and intravenous amphotericin B

Abstract

Objective: Mucormycosis is an aggressive fungal infection which may still cause fatal complications. However, the rarity of this disease has made optimal treatment a controversial issue. This study aimed to evaluate the use of topical amphotericin B in endoscopic management of rhinocerebral mucormycosis.

Subjects and methods: Thirty patients with infection limited to the nose and sinuses were selected. Patients underwent endoscopic debridement of all necrotic tissue; cottonoid pledgets soaked in amphotericin B solution were then placed in the nasal cavity. Subsequently, long-term antifungal therapy was administered.

Results: The overall survival rate was 60 per cent (18 cases); survival rates in the diabetic and malignancy groups were 70.58 and 40 per cent, respectively. Apart from predisposing factors, orbital and maxillary sinus involvement also had a significant correlation with patient outcome.

Conclusion: Topical use of amphotericin B combined with endoscopic surgical debridement, followed by intravenous amphotericin B treatment, may constitute acceptable management for selected patients, with less morbidity than conventional treatments.
