양측 상악동에서 발생한 진균구 3예

The fungus ball form of fungal sinusitis, formerly known as mycetoma or aspergilloma, occurs in immunocompetent individuals and is almost never invasive. It produces minimal symptoms and usually affects only one sinus. It may produce symptoms of chronic sinusitis such as rhinorrhea, nasal obstruction and the sensation of pressure. The most common site is maxillary sinus unilaterally. But the cases that involved bilateral maxillary sinuses have been rarely reported. In this report, we present three cases of the fungus balls which are involved bilateral maxillary sinus. (J Clinical Otolaryngol 2007;18:96–99)
