Background: firearm wounds are relatively frequent and show high incidence at the head and face area. Temporomandibular joint may be involved, and also some important anatomic structures as the facial nerve directing the need for an interdisciplinary team in order to promote an efficient treatment. Procedures: a case report related to a comminuted condyle fracture caused by firearms with a nonsurgical treatment associated to myofunctional therapy. The patient was referred to Speech and Language Pathologist after the conduct of oral and maxillofacial surgery team, without removing the bullet, lodged superficially near the origin of the sternocleidomastoid muscle on the right side; with comminuted condyle fracture and facial nerve damage. Myofunctional evaluation found an important reduction in the mandibular movement amplitude with severe deviations as for the affected side, no contralateral laterality, muscle pain; paralysis and paresthesia on the right side of the face. Myofunctional therapy followed a specific protocol for facial trauma including: drainage of edemas, specific ipsilateral manipulations on jaw muscles; correction and enlargement of the mandibular movements, specific procedures related to facial paralysis and directed functional reorganization. Results: after eight therapy sessions we obtained: mandibular movements with adequate amplitude and symmetry, chewing reorganization, adequacy of swallowing and speech, remission of painful symptoms and remission of paralysis in the medium third of the face. Conclusion: the conservative treatment for comminuted condyle fracture through myofunctional therapy resulted in functional rehabilitation of the jaw and face, directing the movements and stimulating the adequacy of the sthomatognatic functions.
