Abstract
OBJECTIVE
The aim: To study the consequences of temporomandibular joint injury and efficacy of arthrocentesis for treatment of post-traumatic internal temporoman-dibular disorders.
PATIENTS AND METHODS
Materials and methods: 24 patients who experienced trauma history in the head without jaw fractures underwent CT, ultrasound and/or MRI. TMJ ar¬throcentesis was performed according to a modified method of D. Nitzan (1991) under local anesthesia by means of blockade of the peripheral branch of the auricular-temporal nerve on the background of intravenous sedation.
RESULTS
Results: The ages of the patients varied between 18 and 44 years, and mean was 32,58 years. The causes of trauma were diverse, as traffic accident - 3 (12,5%), assault 12 (50%), hit by materials 3 (12, 5%), and fall-down 6 (25%). According to clinical and radiological signs after traumatic temporomandibular disorders, patients were divided into two groups according to Wilkes classification (1989): 13 patients with stage II (early-middle) and 11 - with stage III (middle).The control ultrasound and MRI carried out 3-6 months after arthrocentesis showed no signs of hemarthrosis in 84.61% of patients with intra-articular disorders of the second degree, and in 72.72% of patients with internal disorders of the third degree, the position and function of the articular disc was restored.
CONCLUSION
Conclusions: Arthrocentesis with TMJ lavage is a minimally invasive surgical manipulation that has proven itself in temporomandibular disorders of traumatic origin, in particular after fractures of the articular process of the mandible.
