Abstract
Purpose: Ankylosing diseases of the temporomandibular joint (ADTMJ) in children ─ bone ankylosis and secondary deforming osteoarthrosis (SDOA) lead to an increase in the coronoid process (CP) on average by 1.5 times. The slice computed tomography (SCT) allows fully determining the changes occurring in the bone structures of the joint with its ankylosing diseases. The purpose of the work was to determine the parameters coronoid process, which affects the limitation of mouth opening, and indications for its resection in the ADTMJ, based on the treatment of SCT data. Material and Methods: The subject of the study were 33 SCT in children aged 6 to 14 years with ADTMJ and without lesions of TMJ. Anthropometric measurements of CP in children of the three groups were performed according to the proposed modified scheme of Levandoski panographic analysis. Conclusion: The proposed scheme of anthropometric measurements of SCT allows us to mathematically substantiate the stage of hyperplasia coronoid process in children and to determine the necessity of its surgical correction.
