“…We have previously shown that the fracture fragment of the condyle determines the ramus height of the mandible in children with condylar head fractures treated conservatively. 5 During follow-up, the absorption of the lateral process of the condyle after closed treatment became close to the 'horizontal absorption' until the height (or articular surface) of the lateral condylar process dropped and aligned with the articular surface of the medial process. Closed treatment could not restore the fracture fragment.…”

“…During follow-up, all displaced condylar fragments fused with the ramus stump at the displaced position. The lateral process of the condyle was also found to be resorbed seriously close to the ‘horizontal absorption’ until the height (or articular surface) of the lateral condylar process dropped and aligned with the articular surface of the medial process 5…”

“…The lateral process of the condyle was also found to be resorbed seriously close to the 'horizontal absorption' until the height (or articular surface) of the lateral condylar process dropped and aligned with the articular surface of the medial process. 5 Therefore, more and more surgeons have begun to perform open treatment for condylar head fractures in adults because it facilitates the restoration of the physiological anatomy of the disk and condyle and the potentially immediate functional recovery of jaw mobility. Such a process also allows an immediate functional movement of the jaw and avoids the ankylosis of the TMJ induced by the trauma.…”

This study was performed to explore bone remodelling in children with intracapsular condylar fractures after the condylar fracture fragments were fixed using long screws and to offer possible explanations about the underlying mechanism. Patient and Methods: Records of children (less than 12 y old) who sustained intracapsular condylar fractures and fixed with long screws from May 2012 to January 2015 were retrieved. Age, gender, dates of injury, admission, and discharge, mechanism of trauma, location and pattern of fracture, other mandibular fractures, treatment methods, and time of review were recorded and analyzed. Image dates of pretreatments and posttreatments, including the date of review, were also recorded. Results: A total of 8 patients completed their follow-up, and all patients (n = 5) who were followed up after more than 3 months showed serious resorption of the condylar head. The condylar head resorbed until the height (or articular surface) dropped and aligned with the surface of the screw. The shortest time of absorption, as shown by the computed tomography scan was 106 days, and the longest time was 171 days (average time of 141.8 d).Conclusions: Intracapsular condyle fractures in children should be managed conservatively as much as possible. However, if the height of the fracture fragments drops remarkably, open reduction and rigid internal fixation become possible choices.

Objectives: To determine the frequency of condylar fractures in children presented.Materials and Methods: This descriptive (cross-sectional) study was carried out at 2nd November 2020 to 25th October 2022. A total of 261trauma patients were observed to determine the frequency of condylar fractures in children.Results: A total of 261 maxillofacial trauma patients were included in the study. Among these, 109 (42%) had condyle fracture. Half of the patients (51.4%) were in the age of 11-15 years followed by 6-10 years (35.8%) with mean age of 12 years. Among 109 patients who had mandibular condylar fracture, majority were males (61%) with a male to female ratio of 2:1. Regarding the etiology, the main reason was fall (37.6%) followed by road traffi c accident (26.6%). In relation to the fracture distribution, unilateral condyle fracture (74.3%) predominate the bilateral involvement. More over isolated condyle fractures (56%) were more frequent than fracture at multiple sites (44%) with the most common combination noted was condyle and para symphysis (52%).Conclusion: The majority of patients were toddlers and school going children with malepred ominance. The mandibular condyle was the most frequent fractured site mainly due to fall and RTA. Special precautions should be taken particularly during growing age in order to prevent fall injuries and its subsequent complication.

Objective: In a retrospective study of the effects of different treatment modalities of condylar fractures in childhood on mandibular symmetry and temporomandibular function, the cases selected for this article were adult patients who had sustained a condylar fracture in childhood. The aim was to investigate the effects of condylar fractures in children on the development and function of the mandible and their specific manifestations after the completion of mandibular development. Methods: According to the different treatment modalities, the patients were divided into the conservative treatment group and the open surgical treatment group, and the effects of the 2 treatment modalities on the patients’ condylar healing, the difference in growth ability, and the symmetry of the jaws were evaluated. The effects of different treatment modalities of children’s condylar fracture on the growth, development, and function of the mandible were investigated using the Ai and Di, the grading of the imaging results, and the 3-dimensional CT fixation measurements from the aspects of both clinical examination and imaging examination. Results: The 2 groups had condylar malalignment and condylar morphology abnormality, and there was one case of joint ankylosis in the surgical treatment group. There was a statistical difference in the evaluation of condylar reconstruction between the 2 groups, and the condylar reconstruction in the surgical treatment group was better than that in the conservative treatment, and there was a statistical difference between the condylar length, condylar width, condylar height, and depth of TMJ fossa between the healthy side and the affected side in the closed treatment group. There was a statistical difference in the height of the mandibular ascending branch between the healthy side and the affected side, and the unilateral condylar fracture was treated conservatively; the difference in the bony chin point deviation between the 2 groups was not statistically significant. Conclusion: In children, after conservative treatment of condylar fracture, the growth of condylar process is poor, and the condylar shape and position are not as good as surgical repositioning, but through the proliferation of temporomandibular joint fossa, it can make up for the insufficient height of condylar process, which has no effect on the symmetry of the mandible, and the surgical treatment can achieve good anatomical repositioning, which has a greater effect on the symmetry of the mandible than the conservative treatment.
