[Bilateral chronic dislocation of the temporomandibular joints and Meige syndrome].

Introduction: Chronic dislocation of the temporo-mandibular joint (TMJ) is rare. It occurs when an acute dislocation is left untreated, in certain situations, including severe illness, neurologic or psychiatric diseases or prolonged oral intubation.

Case Report: A 79 years old woman, with Meige syndrome, suffered from bilateral dislocation of the TMJ for over 1 year.

[Facial asymmetries and their skeletal component].

The diagnosis and treatment of facial asymmetries is one of the most difficult challenges in orthognathic surgery. In some cases, the involvement of soft tissue defects or, in other cases, an associated basi-cranial asymmetry can complicate the management. The influence of various components of the cephalic end in the development of the face requires a thorough clinical and radiographic examination including the overall posture of the patient.

[Facial trauma and multiple trauma].

The human face contains the sense organs and is responsible for essential functions: swallowing, chewing, speech, breathing and communication. It is also and most importantly the seat of a person's identity. Multiple trauma adds a life-threatening dimension to the physical and psychological impact of a facial trauma.

[Post-trauma mandibular osteoma].

Introduction: Osteomas are benign bone tumors with a slow progressive growth. These lesions are predominantly located in craniofacial sinuses, but other locations including mandible have been described. Their etiopathogenesis remains controversial.
