Experiments on developing animals showed that mandibular fractures of any location can be complicated by pronounced growth disorders and abnormal development of mandibular bone, leading to deformations of the site of fracture. Abnormal mandibular development was particularly obvious after injuries to the condyle and condylar process, after fractures of mandibular body and angle with dissection of the neurovascular bundle, and in cases with osteomyelitis. Disorders in endochondral bone formation (which is normally most active in the condyle) caused by traumatic processes and disorders in neurotrophic regulation and blood supply to the bone, developing in neurovascular obstruction, underlie the mechanisms of posttraumatic mandibular deformations. These complications were observed in patients with fractures of different sites because of improper joining and fixation of fragments. Children should be regularly checked up after mandibular fractures. Measures aimed at prevention of growth disorders and development of mandibular bone lesions are obligatory at all stages of examination.
对发育中的动物进行的实验表明，下颌骨任何部位的骨折都可能因明显的生长紊乱和下颌骨异常发育而复杂化，导致骨折部位变形。髁突和髁突过程受伤后、下颌体和角部骨折伴神经血管束离断后以及患有骨髓炎的情况下，下颌骨异常发育尤为明显。创伤过程导致的软骨内骨形成紊乱（通常在髁突中最为活跃）以及神经血管阻塞时骨的神经营养调节和血液供应紊乱，是创伤后下颌骨变形机制的基础。由于骨折碎片连接和固定不当，不同部位骨折的患者均出现了这些并发症。儿童下颌骨骨折后应定期检查。在检查的各个阶段，采取旨在预防下颌骨生长紊乱和病变发展的措施是必不可少的。
