[en] Temporomandibular disorders (TMD) are an umbrella term defined as a group of musculoskeletal conditions, affecting the TMJ, masticatory muscles, and craniocervical structures. Among the most common signs of TMD is a forward head posture which is defined as a posture with increased extension of the upper cervical spine (C1-C3) and increased flexion of the lower cervical spine (C4-C7). There are multiple theories that try to explain the association between these two clinical entities, however, it has not yet been clearly explained in the literature. The present review through an advanced search will try to clarify this issue. Objetive. To determine if there is any kind of relationship between forward head posture and temporomandibular disorders. Methods. An advanced bibliographic review was carried out in the PubMed, Scopus, Web of Science, Sportdiscuss, PEDro and Cochrane databases, from February to May 2023, in which works with a maximum of 10 years of publication, in Spanish and/or were included. or English with a validated diagnosis of TMD, who analyzed the possible relationship between these and FHP and the presence of pain in the orofacial region. The measurement of the FHP, pain, range of movement of the neck and jaw, neck disability, severity of TMD as variables of relevant studies are studied. Outcomes. 11 studies were analysed, 10 of them case-control, one cohort and one randomized clinical trial . The quality level of each one of them was examined through the Newcastle-Ottawa scale and PEDro, the level of evidence and degree of recommendation through the CEBM. The results obtained are very heterogeneous in all the variables, and the relationship between the FHP and the TTM is controversial. Conclusions. Currently, there is no consensus in the scientific literature on the relationship between TMD and FHP. Higher quality and more homogeneous studies are required to be able to ascertain the existence or not of this relationship.

[gl] Os trastornos temporomandibulares (TTM) son un termo paraugas definido como un grupo de condicións musculoesqueléticas, que afectan á ATM, aos músculos masticatorios e a outras estruturas craneocervicales. Entre os signos máis comúns dos TTM atópase unha postura adianta da cabeza que se define como unha postura cun aumento da extensión da columna cervical superior (C1-C3) e un aumento da flexión da columna cervical inferior (C4-C7). Existen múltiples teorías que tratan de explicar a asociación entre estas dúas entidades clínicas, con todo, aínda non foi explicada na literatura de forma clara. A presente revisión a través dunha procura avanzada tratará de esclarecer esta cuestión. Obxectivo. Determinar se existe algún tipo de relación entre a postura adiantada da cabeza e os trastornos temporomandibulares. Material e método. Realízase unha revisión bibliográfica avanzada nas bases de datos de PubMed, Scopus, Web of Science, Sportdiscuss, PEDro e Cochrane, desde febreiro ata maio de 2023 nas cales se incluíron traballos con máximo de 10 anos de publicación, en castelán e/o inglés con diagnóstico validado dos TTM, que analizasen a posible relación entre estes e a PAC e a presenza de dor na rexión orofacial. Estúdase a medición da PAC, a dor, rango de movemento do pescozo e mandíbula, discapacidade do pescozo, severidade dos TTM como variables de estudos relevantes. Resultados. Analizáronse 11 estudos, 10 deles de casos e controis, un de cohortes e un ensaio clínico aleatorizado. O nivel de calidade de cada un deles examinouse a través da escala Newcastle-Ottawa e Pedro, o nivel de evidencia e grao de recomendación a través da CEBM. Os resultados obtidos son moi heteroxéneos en todas as variables, sendo a relación entre a PAC e os TTM controvertida. Conclusións. Na actualidade, non existe consenso na literatura científica sobre a relación dos TTM e a PAC. Requírense estudos de maior calidade e máis homoxéneos para poder pescudar a existencia ou non desta relación.
