RESUMEN: Basado en la encuesta de registros relativos a la ubicación y frecuencia de dolor referido en pacientes con trastorno temporomandibular al palpar ciertas áreas preestablecidas, propusimos una division topográfica anatómica de cabeza y cuello para permitir la estandarización y reproducibilidad de los lugares de dolor referido. KEY WORDS: anatomy, referred pain, facial pain, temporomandibular joint disorders, myofascial pain syndromes. The sites that originated more referred pain when palpated were the masseter, temporalis, sternocleidomastoid and trapezius muscles. On palpation of the neck, were the posterior and lateral cervical regions. On palpation of the regions established by the RDC/TMD, the most frequent area of referred pain was the lateral facial region. The region palpated that originated more referred pain was corresponding to the masseter muscle followed by the region of the sternocleidomastoid muscle, regardless of the side palpated. The new regions were defined preauricular, facial lateral, temporoparietal, posterior head, posterior and lateral cervical, anterior cervical and calvaria. The concordance coefficient of Kendall examined the correlation between regions of referred pain concerning to palpated sites. Of the 835 charts reviewed, 419 (50.2%) patients had referred pain on palpation of the regions based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and palpation of the cervical regions, as often analyzed by the Cochran Q test. *** Public Health Department, Universidade Santo Amaro, São Paulo, Brazil.ĪBSTRACT: Based on the survey of records regarding the location and frequency of referred pain in patients with temporomandibular disorder when certain pre-established areas are palpated, we proposed an anatomical-topographical division of the head and neck to allow the standardization and reproducibility of locations of referred pain.
