Computer-guided Versus Conventional Eminectomy

TMJ dislocation occurs in different forms, acute dislocation as a result of trauma or excessive opening, chronic dislocation as a result of capsule laxity due to prolonged disarticulation, and finally recurrent dislocation. Recurrent dislocation is a repeated sporadic acute TMJ dislocation. Unlike chronic dislocation, the mandibular condyle is located in its normal position between dislocation episodes. Recurrent TMJ dislocation treatment modalities can be organized according to the stability factor into ligaments alteration, musculature alteration, and bony anatomy alteration. Nonsurgical/minimally invasive and surgical/invasive therapies have been used. Conservative modalities are usually used before invasive modalities, yet surgical modalities are still superior to non surgical modalities due to its higher success rate. Eminectomy is one of the widely used surgical procedures to manage recurrent dislocation. It is considered as a "rescue procedure" by many surgeons
