Sonographische Normwerte für das Schilddrüsenvolumen Erwachsener – woher kommen sie und wie sind sie zu bewerten?

Zusammenfassung

Der obere Grenzwert für das Schilddrüsenvolumen beträgt bei Frauen 18 ml und bei Männern 25 ml. Diese Referenzgrößen werden fachgebietsübergreifend in vielen Kliniken und Praxen verwendet und gelehrt. Insofern sind sie auch Grundlage therapeutischer Entscheidungen. Doch wo kommen die Normalwerte für das Schilddrüsenvolumen her und auf Basis welcher Untersuchungen wurden sie etabliert? Sollten diese Obergrenzen in der klinischen Routine als universeller Maßstab angewendet werden und welche Faktoren können die physiologische Organgröße beeinflussen? Der folgende Artikel widmet sich einer kritischen Betrachtung der weitverbreiteten Referenzwerte für das Volumen der Schilddrüse in der erwachsenen Bevölkerung.

Abstract

The upper limit for the thyroid volume is 18 ml for women and 25 ml for men. These reference values are used and taught in many clinics and practices across several disciplines. The thyroid volume is a relevant factor for the treatment course. But where do the standard values for thyroid volumes come from, what kind of studies have been carried out to establish them? Should these upper limits be used as an universal standard in clinical routine, and which factors can influence the physiological organ size? The following article is dedicated to a critical review of the commonly used reference values for the thyroid volume of adults.
