In case #1, jaw locking occured 5.5 </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>months after a surgical reduction and internal fixation on the fractured maxilla and mandible. Some plain radiographic x-ray were </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>made but failed to give adequate information in establishing the cause of trismus. The three dimensional computed tomography (3D-CT) </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>was finally made and able to help guide the pre-operative diagnosis and treatment. Two-steps gap arthroplasty were done comprising </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>a gap arthroplasty leading to acceptable outcome. An adult patient in case #2 with a history of trauma at his childhood and bird-like </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>face apprearance clinically, was unable to open the mouth since the time of accident. The patient was diagnosed with bilateral ankylosis </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>of temporomandibular joints. One side (right) gap arthroplasty was done and resulted in normal mouth opening.</em></span></span></span></span></span></span><br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" /></span>
