Patient presenting at a late stage usually presents with large swelling with facial deformity. We present a case of 50 years old male who presented with recurrent ameloblastoma on the left side of the mandible causing facial disfigurement and functional impairment. Adequate removal of the tumor required hemimandibulectomy and intermaxillary fixation was done without any bony reconstruction. We would like to focus on the excellent postoperative result with regard to facial symmetry and functional improvement obtained in this case, though the available management protocols differ and are more advanced in current scenario. This case report gives hope and guidance to the surgeons who face difficulty in managing the deforming benign bony tumors due to the unavailability of facility and funds to reconstruct.展开更多

We present a unique treatment method and magnetic resonance (MR) images of this condition. The patient was a 43-year-old male with a chief complaint of abnormal occlusion. Regarding the present status, there was no occlusion on the right side. No temporomandibular joint pain, myalgia, or clicking were observed while mouth opening. On MR images, the posterior disc displacement without reduction on the right was observed and it was assumed that occlusal abnormality was due to this condition. We treated him with the following methods. After injection into the superior articular cavity with 2% lidocaine, a sodium hyaluronate preparation was injected followed by intermaxillary traction applied using rubber. The recovery of occlusion was confirmed in follow-up at 5 days after treatment. In the 13th days, the intermaxillary traction was removed. On MR images, the right disc condition was changed to anterior disc displacement with reduction. We consider our treatment methods are effective for this clinical condition.展开更多
