Fig. 4From: Temporomandibular joint regeneration: proposal of a novel treatment for condylar resorption after orthognathic surgery using transplantation of autologous nasal septum chondrocytes, and the first human case reportRight and left TMJ CT images from the patient at different follow-up times: external lateral view (0°), frontal view (90°), and internal lateral view 180°) (a) CT images obtained before first orthognathic surgery. Note the presence of degenerative changes in both TMJs, being more severe in the right one (red arrows). (b) CT images obtained 6 months after first orthognathic surgery. Note worsening of degenerative changes in the right side, with a bone cavity formation (yellow arrows). (c) CT images obtained 6 months after cell therapy injection. Note the new cortical and subcortical bone formation (green arrows). (d) CT images obtained 1 year after the injection of the cellular therapy, demonstrating the maintenance of the gains obtained during the former follow-up periodBack to article page
