A Case of Endoscopic Drainage of Pterygoid Fossa Abscess Induced by Fungal Invasion

The infratemporal fossa consists of critical structures affecting patient quality of life. Though abscess formation in the infratemporal fossa is very rare, drainage is highly recommended to avoid severe complications. We recently experienced a rare case of infratemporal fossa abscess. Such an abscess is easy to misdiagnose due to its rarity. Endoscopic drainage of the infratemporal fossa was conducted in this case, and its limited invasiveness was an advantage for a conservative approach. We present this case with a brief review of the approach to abscess of the infratemporal fossa area.
