case_images: The patient was unable to close his mouth with an anterior open bite of 28 mm, bilateral pre-auricular hollowing and deranged occlusion [Figure 1].

case_images: A provisional diagnosis of long-standing bilateral TMJ dislocation was given and a computed tomography scan [Figure 2] confirmed the diagnosis.

case_images: Hence, bilateral condylectomy was performed at the level of the condylar neck to prevent recurrent dislocation and to allow free movement of the lower jaw [Figure 3].
case_images: Apertognathia resolved postoperatively

case_images: Apertognathia resolved, and occlusion was achieved with good occlusal interdigitation [Figure 4].
case_images: Red Arrows indicate bilateral eminectomy and condylectomy in post-operative radiographs
