Condylar fractures are one of the most common types of mandibular fractures and are second only to mandibular body fractures, accounting for about 1/3 of mandibular fractures. angular dislocation of subcondylar fractures, bilateral condylar neck fractures, and combined maxillary (or mandibular) fractures are better treated surgically than conservatively, but the methods of surgery and fixation should be different for different types of condylar fractures. There are numerous methods of staging mandibular condylar fractures, but the purpose of staging is to provide clinical guidance on surgery and treatment methods. According to this principle, we believe that the recommendations of the 1999 International Consensus Conference in Groningen, the Netherlands, classify condylar fractures into intracapsular fractures, condylar neck fractures, and subcondylar fractures according to the height of the fracture end. Intracapsular fractures were divided into three parts, outer 1/3, middle 1/3 and inner 1/3, according to the coronal CT pair by the method of Yang Chi et al. Intracapsular fractures were further divided into four types A, B, C and M according to the location of the fracture line. We believe that these two methods are the most reasonable and basically encompass all clinical types of condylar fractures. However, it is important to mention that this surgery requires a high level of operator familiarity with the structure of the temporomandibular joint and the anatomy of the surrounding parotid gland, blood vessels and facial nerve. The fracture of the condylar neck and subcondylar fracture should not open the joint capsule as much as possible, keep the muscle attachment of the condylar break and the joint surface smooth as much as possible, and perform joint disc repositioning and fixation at the same time when the displacement of the joint disc is found during the operation. The choice of fixation method should be based on the fracture type, size and experience of the surgeon. The titanium nail and plate fixation method is simple and easy, and it is not easy to damage the muscle attachment around the condyle and the cartilage surface and blood supply of the condyle, but it cannot achieve good fixation effect for intracapsular fractures. Therefore, in intracapsular fractures, except for type A fractures with titanium plate fixation, it is recommended to use long titanium nail + wire fixation method to better ensure the stability of fixation. However, this method of fixation is more difficult to operate, and care should be taken to avoid damaging the deep intramandibular artery of the condyle, the muscle attachment around the condyle and the cartilage on the surface of the condyle. The operator should also be familiar with the anterior-posterior, internal and external anatomical patterns of the condyle, and the fracture line should be anatomically repositioned during the operation, which often results in the wrong direction of repositioning of the broken segment for inexperienced operators. The fracture end stability can be achieved by using the appropriate fixation method according to the fracture type, and no fracture recurrence or dislodgement of the fixation device occurred in all cases after surgery. For the selection of the incision, we mostly use a modified auriculotemporal joint incision in front of the scalp and ear, which can be considered as the conventional approach for condylar fracture and joint surgery. Patients with fractures below the sigmoid notch traditionally use a submaxillary incision or a combined intraoral incision for fracture end repositioning and strong internal fixation with titanium plates and nails, with obvious postoperative scarring. With the continuous progress of minimally invasive surgical concepts and instruments that make it possible to avoid submaxillary incision, we adopted intraoral incision endoscopically assisted fracture reduction with titanium plate + titanium nail fixation in patients with 2 lateral subcondylar fractures, and achieved the same efficacy as traditional surgery, which is worth further promotion in the future. In clinical practice, for condylar fractures with functional impairment and displacement, the appropriate surgical and fixation methods can be adopted according to their fracture subtypes to achieve satisfactory treatment results, but the surgical skills and experience of the operator are required to be high.
