Odontogenic keratocysts (OKCs) often occur in the molars in the mandibular ramus; they often progress asymptomatically and are discovered only after widespread development. Some cases of OKC progress to the mandibular condyle; however, very few cases exist only in the condyle. To the best of our knowledge, in all of the previously reported cases, OKCs occurred in the mandibular ramus, which underwent resection. The present study reports the case of a 31-year-old man in whom an OKC (13x12x6 mm) occurred discretely in the base of the condyle, in which the condylar head was successfully preserved. The tumor was removed under general anesthesia using the approach of shaving the anterior surface of the mandible. The extraction cavity was managed using the packed open technique and with an obturator. Approximately 20 months post-operation, the patient remained recurrence-free. This report presents a rare case of an OKC in the mandibular condyle base region. Resection was performed under general anesthesia and the condylar process was successfully preserved.
牙源性角化囊肿（OKCs）常发生于下颌支的磨牙区；它们通常无症状进展，仅在广泛发展后才被发现。部分OKC病例会发展至下颌髁突；然而，仅发生于髁突的病例非常罕见。据我们所知，在所有先前报道的病例中，OKCs均发生于下颌支并接受了切除术。本研究报告了一例31岁男性患者，其OKC（13×12×6 mm）孤立发生于髁突基部，髁突头部得以成功保留。在全身麻醉下采用刮除下颌骨前表面的方法切除肿瘤。拔牙创采用填塞开放技术并使用闭孔器处理。术后约20个月，患者无复发。本报告展示了一例罕见的下颌髁突基部区域OKC病例。在全身麻醉下进行切除，髁突得以成功保留。
