Anatomie und Normvarianten der Nasennebenhöhlen in der Schnittbildgebung

Abstract

CT and MRI are the radiological methods of choice in the diagnostics of diseases of the paranasal sinuses. Detailed anatomical knowledge is mandatory for correct image interpretation. Before endonasal surgery the individually variable anatomic situation has to be known. This article describes radiologically relevant anatomical structures and summarizes normal variations.

Upper respiratory tract disease in captive orangutans (Pongo sp.): prevalence in 20 European zoos and predisposing factors

“…The accompanying indentation in bony structures of the latter could lead to a narrowing of intra‐ and paranasal cavities and drainage pathways in Bornean orangutans. That could explain the higher susceptibility of this species to chronic respiratory signs, as anatomic variations within the nasal and paranasal cavities are also known to predispose humans for sinusitis and thus chronic respiratory signs [8, 37, 38]. Furthermore, obesity in primates has been suggested as a predisposing factor for respiratory infections because obese animals are less active, thus impairing the clearance of respiratory secretions [5, 22].…”

Radiologische Diagnostik der Nasennebenhöhlen

“…3). Ihre Bedeutung kann durch eine geänderte Luftzirkulation oder Blockade der Sinus in der Auswirkung auf die physiologische Drainage der NNH liegen, in anderen Fällen stellen diese Varianten Risiken für einen endonasalen operativen Eingriff dar [13,14,15,16].…”
