ABSTRACT
Objective To observe the temporomandibular joint spaces changes after the plastic surgery of combined zygoma with mandibular angel.Methods We randomly selected 59 patients with prominent zygoma and mandibular angle,screening periodontal disease,TMJ pain and partial jaw.Bilateral zygomatic arch coarctation,jaw edge of the mandibular angle ostectomy and the mandibular body outer panel split were used.All patients accepted CT scan and three-dimensional reconstruction before operation,10 days after operation and 6 months after operation,and then image analysis softwares were used to measure the line distance of corresponding angle (0°,60°,120°,and 180°)at the TMJ sagittal plane.The 0° (EE 'pitch) and 60° (AA'pitch) represented for pre-space,the 60° and 120° (PP'pitch) was upper-space,the 120° and 180° (SS'pitch) was posterior-space.Results 0° and 60° had the same change trend,which slightly increased at 10 days after operation.The difference before operation and 10 days,6 months after operation were not statistically significant (P > 0.05);120° and 180° had the same change trend,which increased at 10 days after operation.The difference between before operation and 10 days after operation was statistically significant (P < 0.05),but the difference between before operation and 6 months after operation was not statistically significant (P> 0.05).Conclusions In the short term after plastic surgery of zygoma combined with mandibular angel,the TMJ upper and posterior spaces are changed,and the interspace reduced.This may indicate that the TMJ has compensatory ability,and short-term changes can return to normal.
