Subacute infratemporal fossa cellulitis with subsequent abscess formation in an immunocompromised patient

To present a case of subacute infratemporal fossa cellulitis with subsequent abscess formation to show important anatomic relationships as they effect presentation and treatment of infections in this area. Case report and brief literature review. The case of an immunocompromised patient who developed subacute infratemporal fossa cellulitis with subsequent abscess formation is presented. A literature review discusses etiology, diagnosis, and treatment of these infections. Careful history and physical examination revealed unilateral facial pain, swelling, and trismus to be caused by an infratemporal fossa abscess. Intraoral drainage and intravenous antibiotic therapy led to resolution of the infection. Infratemporal fossa abscesses are potentially dangerous complications of odontogenic infections. Although clinical diagnosis may be difficult, knowledge of relevant anatomy and pathways of spread allow more effective diagnosis and treatment of these infections.
