A swollen cheek, an unusual course of acute mastoiditis.
An acute mastoiditis can occasionally present as a swelling in front of the ear. An inflammation of the air cells of the mastoid cavity can spread, via the cells in the root of the zygomatic arch, to the soft tissues of the cheek. Unfamiliarity with this underlying cause of a swollen cheek can lead to delay of proper treatment with potential harm to the patient. This case presents such an uncommon form of mastoiditis in a 3-year-old boy; the failure to recognize the disease initially led to extensive osteomyelitis of the temporal bone. CT scanning was important in establishing the cause of the persistently severe condition of the boy, in spite of bilateral myringotomies and mastoidectomy on the right side. Destruction of bone from the zygomatic arch to the suture between temporal and occipital bone was shown. Extensive removal of diseased bone was achieved neurosurgically, thus leading to uneventful recovery.
