The rare anomalies diagnosed in prenatal ultrasonographic examination include Pierre-Robin sequence. The aim of the report was to demonstrate a well-documented case of Pierre-Robin sequence detected by ultrasonography at the 24th week of gestation, present the differentiation of Pierre-Robin sequence in the prenatal ultrasonography and to emphasize the importance of early sonographic diagnosis of the anomaly. The prenatal diagnosis of Pierre-Robin sequence in prenatal ultrasonographic assessment is of great importance as it permits planning further course of pregnancy as well as EXIT procedure and postnatal treatment.
Transmigration is a tooth pathology in which the migrating tooth bud passes the median plane. Methods: This study is a presentation of the diagnostic and therapeutic outcomes in the cases of 4 stomach teeth transmigrations diagnosed in 3 patients with mandibular retrognathia which was a complication after osteitis in the postnatal period and infancy. Results: Extending imaging diagnostics to include CT, most preferably CBCT, makes it possible to precisely evaluate a transmigrated canine’s position and to plan a course of treatment. Conclusions: Planning of the treatment of teeth in transmigration in patients with temporomandibular ankylosis should be done by a team consisting of an orthodontist and a surgeon.
