Accessory maxillary jaws are extremely rare occurrences. Currently, there is only 1 report of bilateral accessory maxillary jaws in the English-language literature. We present a case of a 7-year-old girl with bilateral bony exostoses extending from the maxillary tuberosities. The patient also had restricted protrusive and lateral excursive movements of the mandible. The histologic report revealed teeth in various developmental stages within the bony exostoses. We concluded that these structures were an isolated form of bilateral accessory maxillary jaws.
