Neoplasms of the temporomandibular joint (TMJ) usually mimic common causes of TMJ syndrome, leading to delay in diagnosis. To increase awareness of TMJ neoplasms and establish guidelines for early intervention, we performed a retrospective analysis of a series of patients with neoplasms of the TMJ.
A retrospective review of the records of patients with neoplasms of the TMJ from 1990 to 1997 was done.
Six patients were identified. The neoplasms included benign and malignant neoplasms. The time from initial presentation to final diagnosis was in most cases prolonged, ranging from 3 months to 8 years. Patients typically showed advanced lesions radiographically. All patients required surgical extirpation. Postoperative radiation therapy was used for malignant lesions. Patient outcomes were delineated.
Neoplasms, both benign and malignant, of the TMJ are rare but represent a challenging diagnostic problem. In patients with 1 month or more of recalcitrant TMJ swelling or pain, radiographic imaging may be considered to rule out these rare neoplasms. This may lead to earlier intervention and improved outcome.
颞下颌关节（TMJ）肿瘤通常会模仿颞下颌关节综合征的常见病因，导致诊断延迟。为提高对颞下颌关节肿瘤的认识并建立早期干预指南，我们对一系列颞下颌关节肿瘤患者进行了回顾性分析。
对1990年至1997年颞下颌关节肿瘤患者的记录进行回顾性研究。
确定了6例患者。肿瘤包括良性和恶性肿瘤。从初次就诊到最终诊断的时间在大多数情况下都延长了，从3个月到8年不等。患者在影像学上通常表现为晚期病变。所有患者均需手术切除。恶性病变采用术后放射治疗。描述了患者的预后。
颞下颌关节的良性和恶性肿瘤均罕见，但却是一个具有挑战性的诊断问题。对于颞下颌关节肿胀或疼痛持续1个月或更长时间的患者，可考虑进行影像学检查以排除这些罕见肿瘤。这可能会导致更早的干预并改善预后。
