    Description / Table of Contents: Abstract Purpose. To compare spiral and conventional CT in the staging of carcinomas of the oral cavity, the oropharynx and hypopharynx. Method. Retrospectively 101 conventional CTs and prospectively 107 spiral CTs were analyzed regarding to correct T and N staging. CT results were compared with histological staging. Results. In conventional CT, there were correctly staged 85% of T stages (T1 62%, T2 74%, T3 81%, T4 94%) and 85% of N stages (N0 79%, N1 71%, N2 89%, N3 94%). Spiral CT showed correct results in 84% of T stages (T1 67%, T2 74%, T3 88%, T4 95%) and in 86% of N stages (N0 82%, N1 78%, N2 90%, N3 93%). No statistically significant differences could be found between both CT methods. Conclusion. In spite of the tendency of improved diagnosis of T1, N0 and N1 stages no clear improvement in the staging of carcinomas of the oral cavity, the oropharynx and hypopharynx could be expected by spiral CT.
    Notes: Zusammenfassung Fragestellung. Ziel der Studie war ein Vergleich konventioneller CT und Spiral-CT im Staging von Karzinomen der Mundhöhle, des Oro- und Hypopharynx. Methode. Retrospektiv wurden 101 konventionelle CTs und prospektiv 107 Spiral-CTs auf Korrektheit des T- und N-Stagings überprüft. Als Golden Standard galt das histologische Staging. Ergebnisse. Mit der konventionellen CT wurden jeweils 85% der Tumore korrekt einem T-Stadium (T1 62%, T2 74%, T3 81%, T4 94%) und einem N-Stadium (N0 79%, N1 71%, N2 89%, N3 94%) zugeordnet. Die Spiral-CT stufte 84% der Fälle richtig im T-Stadium (T1 67%, T2 74%, T3 88%, T4 95%) und 86% im N-Stadium (N0 82%, N1 78%, N2 90%, N3 93%) ein. Die Unterschiede im T- und N-Staging zwischen beiden CT-Methoden waren statistisch nicht signifikant. Schlussfolgerung. Trotz der Tendenz der besseren Beurteilbarkeit von T1-, N0- und N1-Stadien ist von der Spiral-CT keine eindeutige Verbesserung im Staging von Karzinomen der Mundhöhle, des Oro- und Hypopharynx zu erwarten.
