Orthokeratinized odontogenic cyst (OOC) is a developmental cyst of jaw and was initially considered by the World Health Organization (1992) as the uncommon orthokeratinized variant of odontogenic keratocyst (OKC). However, studies have shown that OOC has peculiar clinicopathologic aspects when compared with other developmental odontogenic cysts, especially OKC. So orthokeratinized odontogenic cyst now stands out to be a distinct entity. Clinically, it occurs as a single cyst, shows a predilection for males and is most often found in the second to the fifth decade. Its bilateral occurrence is extremely rare. The purpose of the article is to present a rare case of bilateral OOC arising in the mandible and review the literature on bilateral occurrence of this lesion.
正角化型牙源性囊肿（OOC）是一种颌骨发育性囊肿，最初世界卫生组织（1992年）将其视为牙源性角化囊肿（OKC）的罕见正角化型变体。然而，研究表明，与其他发育性牙源性囊肿，尤其是OKC相比，OOC具有独特的临床病理特征。因此，正角化型牙源性囊肿现在已成为一个独特的实体。临床上，它表现为单个囊肿，男性多见，最常发生于20至50岁之间。其双侧发生极为罕见。本文旨在介绍一例罕见的双侧下颌骨OOC病例，并复习有关该病变双侧发生的文献。
