Zusammenfassung
Hintergrund: Obwohl bereits zu Beginn dieses Jahrhunderts erste Ansätze zur bildgebenden Diagnostik
im Kopf-Halsbereich erkennbar waren, sind es vor allem die vergangenen 15-20 Jahre,
die den Stellenwert dieser Untersuchungstechniken neu definiert haben. In der vorliegenden
Übersichtsarbeit werden die aktuellen Indikationen bildgebender Verfahren in den verschiedenen
Regionen des HNO-Bereiches vorgestellt, ihre Aussagefähigkeit gewertet und ihre Stellung
innerhalb des diagnostischen Vorgehens bei Erkrankungen im Kopf-Halsbereich aus heutiger
Sicht definiert.
Summary
Background: The first conventional x-rays of the paranasal sinuses were reeeived in 1897, just
two years after the detection of x-rays. During the following decades several modifications
and extensions of conventional radiologic technigues were developed, but routine imaging
procedures of the head and neck were mainly restricted to pictures of the paranasal
sinuses and the temporal bone. In the fifties, tomography was developed, which gave
us a more detaiied insight of the anatomy and pathology of the paranasal sinuses and
temporal bone. During the last two decades the development of new technigues, i.e.
computed tomography (CT) and magnetic resonance imaging (MRI), has significantly increased
the importance of modern imaging for the diagnostic evaluation of head and neck diseases.
These diagnostic tools enable us to visualize anatomical struetures and pathological
entities with an aecuraey never been expected beforehand. The pace of the improvement
of these diagnostic tools, however, reguires that both radiologist and otorhinolaryngologist
keep up with the adeguate indications of CT and MRI in the different areas of the
head and neck. A dose relationship and cooperation between radiologist and ENT surgeon
is therefore indispensible for a fruitful and cost-effective use of modern imaging.
Otherwise the patient is exposed to modern medical technology without an eguivalent
benefit. The purpose of the present paper is mainly to give an update and state of
the art of modern imaging techniques in otorhinolaryngology, head and neck surgery.
Different areas i.e. paranasal sinuses, temporal bone, salivary glands, oral cavity
and oropharynx as well as the neck are discussed in terms of adeguate indications
for modern imaging in the diagnostic evaluation of different lesions.
