A Case of Odontogenic Infratemporal Fossa Abscess / 대한이비인후과학회지

ABSTRACT

Infratemporal fossa abscess is difficult to diagnose by conventional physical examination because of the anatomic location of this structure. Infratemporal fossa abscess has been seen secondary to maxillary sinus fracture and infections involving the maxillary molars. It is difficult to observe on plain films but is readily apparent on CT evaluation. The loss of the retromaxillary fat plane is the most notable feature. Streptococcus spp and Bacteroides spp have been isolated from the abscess. Therapy consists of incision and drainage, and appropriate antibiotic therapy. The following case report and review of the literature are offered in hope of alerting physicians to the occurrence of this disease and to the circumstances in which the diagnosis should be actively excluded.
