Orofacial Pain In Ernest's Syndrome: A Systematic Review
Objectives: The aim was to determine the association between Ernest's síndrome (ES), the stylomandibular ligament and temporomandibular disorders. Methods: The databases EBSCO HOST, EMBASE, JSTOR, LILACS, MEDLINE, SAGE, Science Direct, SCOPUS, SpringerLink, Willey Blackwell and WoS; the SciELO library and the Trip search engine were searched using “STYLOMANDIBULAR LIGAMENT” and “ERNEST SYNDROME” as keywords, “AND” and OR as Boolean term. The inclusion criteria were: studies to evaluate the clinical and therapeutic ES’s characteristics, without language filter or year of publication. Results: Eight hundred and thirty articles were found in the initial search. Then, the titles were analized using the selection criteria: fifty five articles were obtained. Then, the duplicated filtres were applied, obtaining twenty two articles. Then, only ten articles were selectioned by analizing abtracts. Finally three articles were selected by analizing full text.
After analyzing the information, it could be suggested that there is a non-negligible number of patients underdiagnosed with ES as comorbidity to other TTM. It is very important when we examinate patients who have these clinical manifestations, to considerer that the anesthetic block in the mandibular angle with subsequent remission of the symptomatology is currently the diagnostic criteria by excellence. Considering a pathophysiological base similar to tendinitis of the temporal muscle tendon, it would be interesting to evaluate the administration of systemic anti-inflammatory drugs as a therapeutic alternative. However, infiltration with peri-ligament corticosteroids seems to be a simple and uncomplicated procedure that can provide significant symptomatic relief. Conclusions: The articles analized have allowed to better the understanding about Ernest's syndrome, however the current evidence is small, heterogeneous and poor in methodological quality, so it is necessary to get more information, specifically more extensive and larger studies and better methodological designs.
