To conduct a systematic review of the available evidence regarding the clinical characteristics and treatment of Ernest syndrome.
A systematic search was carried out in the EBSCOhost, Embase, MEDLINE, ScienceDirect, Scopus, Web of Science, and Trip databases. The free terms "stylomandibular ligament" and "Ernest syndrome" were used, and the Boolean operator "OR" was used for connection of the terms. The research protocol was registered in PROSPERO (CRD42018112914). The results of this study are presented according to the PRISMA statement, and risk of bias was assessed according to the Quality Assessment Tool for Quantitative Studies of the Effective Public Health Practice Project.
A total of 57 articles were found, 5 of which met the selection criteria and were included in this review. The selected articles represent a population of 81 patients with primarily unilateral pain in the periauricular and mandibular areas. Diagnosis was established according to clinical history, recognition of pain on palpation of the mandibular angle, and remission following infiltration with local anesthesia. Concerning the treatments applied, infiltration with corticosteroids was highly successful, as was partial resection of the stylomandibular ligament and part of the styloid process. Furthermore, in refractory cases, the application of radiofrequency thermoneurolysis was described.
The analyzed studies allow a better understanding of Ernest syndrome and the proposal of a tendinosis model for this condition. However, the evidence is scarce, and it is therefore necessary to carry out additional studies with better methodologic designs.
系统回顾关于 Ernest 综合征的临床特征和治疗的现有证据。
在 EBSCOhost、Embase、MEDLINE、ScienceDirect、Scopus、Web of Science 和 Trip 数据库中进行了系统检索。使用了自由词“茎突下颌韧带”和“Ernest 综合征”，并用布尔运算符“OR”连接这些词。研究方案在 PROSPERO（CRD42018112914）中进行了注册。本研究的结果根据 PRISMA 声明呈现，根据有效公共卫生实践项目的定量研究质量评估工具评估偏倚风险。
共发现 57 篇文章，其中 5 篇符合入选标准并纳入本综述。入选的文章代表了 81 例主要表现为耳周和下颌区域单侧疼痛的患者人群。根据临床病史、触诊下颌角时疼痛的识别以及局部麻醉浸润后的缓解情况来确立诊断。关于应用的治疗方法，皮质类固醇浸润效果显著，茎突下颌韧带和部分茎突部分切除术也是如此。此外，在难治性病例中，还描述了射频热神经松解术的应用。
分析的研究使我们更好地了解了 Ernest 综合征，并提出了这种疾病的一种腱病模型。然而，证据稀缺，因此有必要进行设计更好的方法学的额外研究。
