Abstract

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.

摘要

副上颌骨是极其罕见的。目前，英文文献中仅有 1 例双侧副上颌骨的报告。我们报告了一例 7 岁女孩双侧上颌骨结节处骨性外生骨疣。患者还伴有下颌骨前伸和侧方运动受限。组织学报告显示骨性外生骨疣内有不同发育阶段的牙齿。我们认为这些结构是一种孤立的双侧副上颌骨形式。
