Aim. The proper treatment for Aspergillus mycetoma (AM) of the maxillary sinus is a complete removal of the sinus fungal masses and improvement of aeration for the involved sinuses. We report our experience in the treatment of AM of the maxillary sinus by functional endoscopic sinus surgery (FESS).
Methods. Thirteen immunocompetent patients with AM underwent FESS under general anesthesia. Mycotic concretions were endonasally removed through the enlarged maxillary natural ostium. Care was taken to avoid any removal of the maxillary sinus mucosa. Only in one case complete removal could not be achieved and therefore we opened the maxillary sinus via the canine fossa and cleared it of fungal masses. Follow-up has ranged from 6 months to 4 years after surgery. Patients were all closely followed postoperatively with serial endoscopic examinations in order to verify the maintenance of opening of the maxillary natural ostium.
Results. Histological examination was positive for Aspergillus in all the patients. Postoperative radiographs and endoscopic examinations revealed maintenance of the antrostomy performed during FESS without mucosal degeneration and no evidence of recurrence. All patients were free of symptoms after a mean follow-up of 31 months. None of the patients required a second procedure.
Conclusion. Surgical treatment of AM with FESS appears a reliable and safe surgical treatment. Sinus physiology is preserved in the event of a future bone reconstruction for prosthetic purposes.
