Maxillary Sinus Mucocele With Fungal Ball

J Craniofac Surg. 2023 Nov-Dec;34(8):e759-e760. doi: 10.1097/SCS.0000000000009632. Epub 2023 Aug 18.


Mucocele is a benign, expansile, and oppressive lesion, more common in the frontal and ethmoid sinus and less in the maxillary sinus. Sinus mucocele mainly causes cheek swelling pain and nasal obstruction. In some cases, the paranasal mucocele grows large enough to compress periorbital structures and lead to impaired vision. Generally, mucocele is full of simple mucus, but pathogens can be found if co-infected, which means a poor prognosis. Functional endoscopic sinus surgery is an effective treatment for this disease. Here, the authors report a case that a mucocele occurred in the maxillary sinus, and a fungal ball was also found during the operation, which is a result of Paecilomyces farinosus co-infection.
