[Potential of temporal bone CT in the study of external acoustic meatus in health and pathology].

Computed tomography (CT) was used to examine 50 patients (100 temporal bones) aged from 10 days to 60 years with healthy external acoustic meatus (EAM) and 53 patients (62 temporal bones) aged from 4 to 75 years with symptoms of acquired stenosis, atresia or obturation of the external acoustic meatus. Polyposition CT of the temporal bone including axial and coronary projections is the most informative method of visualization of the EAM bone part. In axial projection the assessment covers the anterior and posterior walls of the EAM, in the coronary one - the upper and the lower walls.

[Temporal bone CT in the diagnosis of acquired diseases of the external auditory canal].

CT was used to examine 50 patients (100 temporal bones) aged 10 days to 60 years who had no signs of lesion of the external auditory canal (EAC) and 23 patients (27 temporal bones) aged 13 to 65 years who had clinical manifestations of acquired stenosis or obturation of the EAC. Polypositional CT of the temporal bone is the most informative technique of visualization of the osseous part of the EAC, at the same time the anterior and posterior EAC walls were evaluated in the axial projection and the upper and lower EAC walls were assessed in the coronary projection. According to CT data, formation of the osseous part of the EAC occurs within the first 7 years of a child's life.

[Potentialities of echography in the diagnosis of uncomplicated acute appendicitis in children].

Ultrasonography was performed in 97 children admitted to hospital for suspected acute appendicitis. According to the results of primary surgical examinations and the magnitude of clinical manifestations, all the patients were divided into two groups. Group 1 comprised 53 patients with clinically diagnosed acute appendicitis and with a worded indication for an emergency surgical intervention; this group was formed for describing the ultrasonic semiotics of different types of acute appendicitis in children.

[X-ray diagnosis of rare esophageal diseases in children].

Clinical and X-ray studies of 300 children aged hours to 14 years who had abnormalities of the esophagus have revealed its atresia with or without tracheoesophageal fistulas in 77 subjects, that with congenital narrowings in 21. It was proved that some varieties of atresias might be roentgenologically detected and comprehensive studies should be carried out to determine fistulas in the completely patent esophagus. Despite the age, all children with esophageal atresia with a lower fistula were found to develop catarrhal and erosive esophagitis and "corrosive" pneumonia.
