A 10-year-old girl presented to the pediatric emergency department with a 1-week history of painless swelling of the right cheek. She denied any fever, upper respiratory tract symptoms, cough, dental pain, or ocular disturbance. Her medical history was benign.
Physical examination revealed a well-developed, well-nourished afebrile girl in no acute distress. She had an obvious intraorbital asymmetry of the right face, but she exhibited no discomfort with palpation of the infraorbital region. The area was soft and without erythema, induration, or fluctuance. Extraocular movements were normal. The nose had normal mucosa with no discharge. Examination of the oral cavity revealed swelling of the right posterolateral maxillary alveolar ridge and a "spongy" consistency of the bone on palpation. The second and third upper-right molars were loose and maloccluded.
Roentgenograms of the sinuses were obtained (Figs 1 and 2).
