BACKGROUND: facial mimicry in the paralysis of the face that occurs because of a trauma in the face. PROCEDURES: case study of facial mimicry of a patient with peripheral facial paralysis, on the right side of the face, with sequels that happened because of a trauma because of a fire gun projectile; a young man, a self-employed trader. A documental and photographical analysis was held through the anamnesis and graduation scale of House and Brackmann's facial paralysis. RESULTS: in the evaluation of the facial paralysis, in a resting state, we found on the right side (the injured one): diversion of lip commissure, diversion of the filter, more elevated nostril and more open eye. In movement, yet on the side of the injury, it was observed: elimination of frontal wrinkles , incompetence in the ocular closure and in the complete closure , absence of elevation of the nostril , a more pronounced nasolip rhyme, lip protrusion diverged to this side , little lip retraction , destruction of the inferior lip , elevated lip commissure , diversion of the filter, reduced capacity of inflating the cheeks. The patient presented synkinesia of eyes / lips and contraction with hypertonia of frontal, procerus, lifter of the nose's wing, risorius, higher zygomatic, lower zygomatic, lifter of superior lip, depressive of inferior lip, mentalis on the side of the lesion and the fracture happened on the right condyle and the patient reported orofacial pain when sleeping and chewing on the injured side. CONCLUSION: the lesion of the facial nerve that was associated with the face trauma provoked the alteration of the facial mimicry on the right side and generated disfiguration and disturbances in the chewing act.
