[A rapid decalcification method for the production of serial sections of the larynx]

The technique of large serial sections of larynx has proved useful for the examination of growth tendencies of laryngeal carcinoma. A new method using RDO solution (rapid decalcification agent) is presented. The embedding is done in paraffin. The thickness of the individual histological sections is 5 micron. The overall time for completing the procedure is 9-10 days. Rapidity and good preservation of histological structures are the main advantages of this method.
