A Rare Case of Recurrent Temporomandibular Joint Dislocation Associated with Pneumatized Articular Eminence. Surgical Treatment by Eminoplasty with Miniplates

Performing a surgical treatment for TMJ dislocation combined with pneumatized articular eminence is a technical challenge for the surgeon, as this condition has a low population frequency. This article aimed to present one case of recurrent temporomandibular joint dislocation treated by eminoplasty with miniplates in a patient affected by bilateral pneumatized articular eminence. After 15 months of follow-up, the patient presented approximately 43 mm of interincisal distance. The miniplates remained in position with no fracture signs, and there was satisfactory clinical evolution with no more dislocation episodes. Eminoplasty with miniplates for the treatment of temporomandibular joint dislocation has been shown to be effective in a patient affected by bilateral pneumatized articular eminence. Although, more time is needed to evaluate long-term effectiveness.
