Ganglion cyst of the temporomandibular joint (TMJ) is an uncommon pathology with uncertain etiology. There is no consensus on their management. The current systematic review aimed to discuss the clinical and histopathological features of ganglion cysts of TMJ, to aid in appropriate treatment. A literature search was done and a total of 20 cases were retrieved from published databases such as PubMed, SCOPUS, and Google Scholar. The cyst presented with swelling in all the cases followed by pain (50 %) and trismus (35 %) as other common symptoms. Though CT and MRI proved helpful in determining the location of the cyst, a histopathological examination was essential in concluding its final diagnosis. It is a pseudocyst lined by dense fibro-connective tissue with myxoid tissue degeneration. Histologically, it is essential to distinguish them from the clinically and radiographically similar true cyst of TMJ, synovial cyst. The lining of ganglion cyst is devoid of epithelium and synovial cells. Surgical excision was found to be the treatment of choice with minimal recurrence (10 %) being reported.
颞下颌关节（TMJ）神经节囊肿是一种罕见的病理学疾病，其病因尚不确定。目前对于其治疗方法尚未达成共识。本系统综述旨在讨论 TMJ 神经节囊肿的临床和组织病理学特征，以辅助选择适当的治疗方法。通过文献检索，从 PubMed、SCOPUS 和 Google Scholar 等已发表数据库中检索到 20 例病例。囊肿的表现为所有病例均有肿胀，随后出现疼痛（50%）和牙关紧闭（35%）等常见症状。尽管 CT 和 MRI 有助于确定囊肿的位置，但组织病理学检查对于确定其最终诊断至关重要。它是一种由致密纤维结缔组织和黏液样组织变性组成的假性囊肿。从组织学上，有必要将其与临床上和影像学上相似的 TMJ 真性囊肿，即滑膜囊肿相鉴别。神经节囊肿的内衬无上皮和滑膜细胞。手术切除被认为是首选治疗方法，报道的复发率最低（10%）。
