Korotchenko G. Surgical treatment of osseous ankylosis and secondary deforming osteoarthroses of the temporomandibular joint (TMJ) of children.

This paper is devoted to the justification of the use of the most informative methods of the TMJ examination, the elaboration and implementation of the latest techniques of surgical treatment of osseous ankylosis and SDOA of the TMJ of children into clinical practice. The thesis is based on the analysis of 42 archival case histories, examination and treatment of 63 children aged from 2 to 17 years old with osseous ankylosis and SDOA of the TMJ. The main causes of the pediatric initial bony diseases of the TMJ and the principles of their diagnostics have been outlined. The indications for the application of extra methods of examination of children with osseous ankylosis and SDOA of the TMJ (orthopantomography, CT) have been determined, the modern informative methods for diagnostics and treatment planning – 3D-CT modeling, computer program “SurgiCase CMF”, stereolythographic modeling – have been used. The medical diagnostic algorithm for children suffering from osseous ankylosis and SDOA of the TMJ has been suggested. New bland techniques to treat SDOA of the TMJ have been devised, making it possible to restore the articular function and save the undamaged sections of the articular head of the condylar process. To treat osseous ankylosis of the TMJ, certain methods that allow to restore the articular function and to partially eliminate microgenia within one stage of treatment using the coronoid process and the technique of compression-distraction osteosynthesis application have been proposed. Clinical effectiveness of the surgical treatment techniques suggested to manage initial bony diseases of the TMJ has been proven, indications for their use depending on the diagnosis and age of the child have been identified.
