How is the procedure performed?
Small quantities of barium are introduced via the nostrils and oral cavity. This is to ensure the nasal passages, nasopharynx and mouth are coated to enhance the study. The studies are performed in the basal and lateral projections. Static images with and without phonation are performed. Exposures are made during sustained speech to asses for velopharyngeal closure.
Is it painful?
No. It is usually well tolerated by the children.
Will my child be exposed to high levels of radiation?
No. The radiation dose is low.
