Flautists are at risk of developing muscular and joint pain. While playing the flute muscles of the maxillofacial region do not work physiologically. In addition, the musicians stay in an asymmetrical posture for a long time and often experience stress during performance. All these factors can affect masseter and temporal muscles and consequently lead to temporomandibular joint dysfunction (TMD). The aim of research was to investigate the state of the temporal and masseter muscles of flautists by means of electromyography in comparison to the control group. Electromyography of the temporal and masseter muscles was performed in 30 flautists and 30 control subjects aged 18 to 35 with the BioEMG from the BioPAK complex (BioResearch, USA). Electromyography at rest registered increased bioelectric potential of the temporal and/or masseter muscles in a subgroup of flautists who play more than 3 hours a day in 37.5% of cases. In a clench test both musicians and control subjects showed asymmetrical work of masticatory and temporal muscles, while in the control group, symmetry below 50% was noted only in the work of the temporal muscles. Synergy between temporal and masseter muscles less then 50% was 1.3 times more common in the control group than among flute players though right-sided disorders were more common in flute players. Electromyography of masticatory muscles is an important stage in a comprehensive examination of the TMJ condition, however, this method cannot be used as the single one or decisive one to diagnose the professional pathology of flautists.
