A 14-year-old boy visited the emergency department (ED) with a 1-month history of
progressive difficulty opening his jaw and moderate pain when chewing. He reported
having suffered a maxillofacial trauma 4 weeks earlier when he accidentally collided
with a glass window after fainting. He had previously presented to his local hospital,
where a left facial hematoma had been drained and a 1-cm incised wound had been sutured
on his left cheek. Initial examination showed a scar on the cheek and revealed a limitation
to open his mouth (1 cm), with deviation of the jaw to the left side and pain when
moving the jaw. There was no facial paralysis or anesthesia. The palpation of his
oral cavity was normal. The rest of his medical history was not contributory. A panoramic
radiograph that was initially obtained in the ED revealed a partially radiopaque and
well-defined rectangular image of approximately 3.5 cm in length in the tuberosity
of the left maxilla (Figure 1). A non-contrast computed tomography (CT) scan was ordered.
