Patients
This clinical trial included patients treated in the oral and maxillofacial centre of the study hospital between the years 2010 and 2013. During the initial screening, 23 patients were selected based on clinical and imaging examinations. The clinical examination assessed the maximum incisal opening (MIO), number of episodes of dislocation, necessity of professional assistance for reduction, and vertical dimension of the lower facial third. Panoramic and TMJ radiography, in the closed and open
Results
Of the 23 patients initially selected, 10 were excluded since they were able to self-reduce the condylar dislocation and two were excluded as they presented fewer than three episodes in a 6-month period. The final sample comprised 11 patients with chronic recurrent TMJ dislocation; eight were women and three were men, and their average age was 27.8 years (range 15–60 years). The average duration of symptoms was 63.9 months, ranging from 4 months to 16 years. The number of dislocations prior to
Discussion
Historically, the gold standard treatment for recurrent TMJ dislocation is eminectomy, with success rates higher than 85%.17, 18, 19, 20 Although this technique is favourable in terms of the success rate, it is an invasive procedure, requiring a hospital stay and skin incision, with an increased risk of facial nerve injury and unaesthetic scars. Even if frequently performed with rotatory instruments, irregular areas and bone spicules may be left behind inadvertently and lead to crepitation or

Bilateral Dislocation of the Temporomandibular Joint in Children
2018, Journal of Oral and Maxillofacial SurgeryCitation Excerpt :No surgical treatments for recurrent nontraumatic TMJ dislocation in children have been reported. Apart from aggressive approaches that are obviously not recommend in young children, such as the Myraugh procedure, injection of blood or sclerosing agents into the TMJ has been reported in adults18 to induce fibrosis and prevent recurrence. This approach is not appropriate in pediatric populations with major growth potential in the TMJ region.
