Abstract:

Radiological examinations are used as a major tool for diagnosis of congenital and acquired facial bone defects and deformations. The results of the paper are based on analysis of x-ray examinations of 2000 patients. Panoramic zonography was the most frequently used procedure. Zonography shows origin and size of defects, their external contours, structure of mandibula. Use of spiral CT is obligatory in cases of nazo-orbital deformatoions, defects of facial and brain scull bones. CT helps to define extact size of bone defects and to make caclulations for planning surgical interventions. Algorithm for examinations of patients with congenital facial bone deformations should include films, made in anterior and lateral projections, made in teleroentgenographgic mode for vizualisation of soft tissues. In cases of systemic bone diseases, standart films and zonogramms of most informative regions are sufficient.

Abstract:

Purpose. To perform complex and informative radiologic assessment of temporomandibular joints (TMJ)

Material and methods. Patients were divided into 2 groups: 1850 children and adolescents with malocclusions (Group 1), and 2150 adults with edentulous spaces or dental prostheses of different types (Group 2). Panoramic zonograhy spiral and conus computed tomography (CT), orthopantomography were performed in all the cases

Results. There were no osteal lesions of TMJ in Group 1. Intra-joint lesions of different types normalized on opening of mouth in the majority of cases, and only 22% of patients in Group 1 presented improper articular heads position. In Group 2 TMJ arthrosis was diagnosed in 29% of patients, and 25% presented uni- and bilateral restriction or uni- and bilateral subluxation.

Conclusions. The data indicates high incidence of muscles dysfunctions and TMJ lesions of muscular origin that demand orthopedic correction.
