Learning objectives

Briefly review of the radiological anatomy of the oral cavity and consider normal findings in CT scans of the air-distended oral cavity.
Provide a detailed guide for the “puffed cheek” CT technique.
Demonstrate the spectrum of findings in oral cavity tumors imaging carried out by means of contrast enhanced multi-detector computed tomography (MDCT) that is supplemented with this dynamic maneuver.
Mention some difficult situations and pitfalls.
