Представлено описание случаев раздвоения мыщелкового отростка нижней челюсти, которые были выявлены с помощью многосрезовой компьютерной томографии (МСКТ) и конусно-лучевой компьютерной томографии (КЛКТ) у пациентов без клинических симптомов поражения височно-нижнечелюстного сустава. Данная патология является редкой формой эмбриопатии и развивается как следствие нарушения морфогенеза мыщелкового хряща. По рентгенологическим проявлениям она схожа с деформацией головки нижней челюсти, которая происходит в результате прогрессирования воспалительного процесса и ремоделирования суставных поверхностей. Методы конусно-лучевой и спиральной компьютерной томографии обладают достаточной разрешающей способностью для дифференциальной диагностики врожденной и приобретенной патологии височно-нижнечелюстного сустава.

 

This article describes the clinical cases of doubling of the mandibular condylar process, which is detected by means of multislice spiral computed tomography (MSCT) and cone beam computed tomography (CBCT). The patients had no clinical symptoms of temporomandibular joint disorders. This pathology of the temporomandibular joint is a rare form of embryopathy and develops as a consequence of a violation of the mandibular condylar cartilage morphogenesis. Its radiographic signs are similar to the deformation of the mandibular condyle, which is a result of the progression of inflammation and remodeling of joint surfaces. Methods of CBCT and MSCT possess sufficient resolution for the differential diagnosis of congenital and acquired pathology of the temporomandibular joint.
