Description

The use of compression plates for osseous fixation in the inferior maxilla causes some problems for radiation therapy. The retrodiffusion of electrons from the metal implant induces an increased dose at the surface and especially at the metal border. A dose increase up to 40% is demonstrated for the central ray by means of thermoluminescent dosimetry. A dose decrease of up to 90% is measured for 6 MeV behind the inhomogeneity. (orig.)

Abstract (German)

Die Strahlentherapie im Bereich des Unterkiefers wird problematisch, wenn zur Knochenfixierung Kompressionsplatten verwendet werden. Durch das Metallimplantat kommt es infolge der Rueckstreuung von Elektronen zur Dosiserhoehung an der Oberflaeche und besonders ausgepraegt unmittelbar an der Grenzstelle zum Metall. Mit Hilfe thermolumineszenzdosimetrischer (TLD) Untersuchungen ist eine Dosiserhoehung bis zu 40% im Zentralstrahl nachweisbar. Der Dosisverlust hinter der Inhomogenitaet betraegt bis zu 90% fuer 6 MeV. (orig.)
