“…[32] Studies have shown that depletion of macrophages from the time of injury or reduction of macrophage-associated inflammatory factors may affect fracture healing. [ 33] In the study of TMJA, Zhao et al [ 34] found that the number of macrophages was large in the early stage of the TMJA animal model of New Zealand rabbits. Interestingly, once the number of macrophages was inhibited during the operation of the TMJA animal model, the degree of bone stiffness could be reduced, and the expression of cartilage-related genes was also reduced.…”

Temporomandibular joint (TMJ) is a synovial joint composed of condyle, articular disc, temporal fossa and other structures. TMJ is prone to joint diseases due to its frequent activities and bite force. Temporomandibular joint ankylosis (TMJA) is a serious joint disease, which can lead to fibrous adhesion or bone adhesion within the joint, affect mandibular movement and cause facial deformity. Previous studies have shown that trauma, infection, systemic diseases and other causes can cause TMJA, among which trauma factors account for about 90%. The pathogenesis of traumatic TMJA is complex, treatment is difficult and there is a certain recurrence rate. However, the pathogenesis of traumatic TMJA has not been truly revealed, and animal model studies vary. In this article, the related factors and pathogenesis of traumatic TMJA were discussed.

“…Simultaneous arthroplasty and distraction (SAD) 3,35,42-52: It was first performed in 1999 by Papageorge and Apostolidis. 21 Simultaneous arthroplasty and distraction was preferred as it allowed mouth opening by fused joint resection, reduced airway resistance, reconstructed ramal height, and corrected asymmetry by lengthening of the mandible in a single surgery (Table 4). A comparison of Prearthroplasty and simultaneous distraction showed that although prearthroplasty DO provides better control of the distracting segment, but unlike simultaneous distraction, it bears a disadvantage that the final mandibular position cannot be predicted as the final mandibular position tends to change due to muscle pull after the release of ankylosis.…”

“…earlystage relapse. Condylar remodeling after MDO has not been well studied, 10,11,12,13,14 and the results of experimental studies cannot be translated into the scenario in patients with deficient soft tissue and abnormal TMJ before distraction like CFM. 15,16 Unlike orthognathic surgery, the risk factors for CR after MDO are poorly evaluated.…”

Objective To investigate condylar bone density (BD) in children with craniofacial microsomia (CFM) and identify factors that contribute to early stage condylar resorption (CR) after mandibular distraction osteogenesis (MDO). Design Retrospective study. Setting Craniofacial department of a plastic surgery hospital. Patients Fifty-one children with CFM classified as Pruzansky IIa based on complete pre-(T0) and post-MDO (T1) computed tomography (CT) data. Intervention and Main outcome measurements Mimic 21.0 (Materialise Inc., Belgium) was used to measure bilateral BD and condylar height (CH) and volume (CV) of affected side. Children were split into groups based on either affected side BD or the distraction length (DL,25 mm as cutoff) .Bilateral BD was compared using a paired t-test in each group. The CH and CV of affected side at T0 and T1 were compared. The relative values of the CH and CV (CH ratio) and the volume (CV ratio) of the affected side were compared across the groups. Results The BD was lower on affected side than on unaffected side. Regarding BD, CH and CV decreased after MDO in group I, while the CH ratio and CV ratio of group I was lower than that of groups II and III. Regarding DL, the CV ratio was lower in Group L than Group S. Conclusions The condylar bone quality on affected side is compromised in type IIa CFM. A low BD in combination with a larger distraction distance may increase the risk of CR; therefore, MDO in patients with such characteristics should be postponed.
