Aneurysmal bone cyst of the jaws. Review of the literature and report of 2 cases.
Strictly speaking, the aneurysmal bone cyst is not a true cyst. It is a lesion characterized by replacement of bone by fibro-osseous tissue containing blood-filled cavernous spaces. It is usually treated by surgical curettage, and access within the jaws may sometimes be difficult. We reviewed the world literature and found 63 cases of aneurysmal bone cysts involving the face, 22 reported in the maxilla, and 63 in the mandible. One was found in the zygomatic arch. Of the patients reported, 88% were younger than 30 years old; there was an equal sex distribution. Included in this report, are two cases of our own, one involving the maxilla and one the mandible.
