OBJECTIVES. The purpose of this article is to highlight some terms which have been ingrained in the rhinosinusology literature.
MATERIAL AND METHODS. It regards the term “accessory ostium” and the term “septal deviation”. The well-known and deeply ingrained term “accessory ostium” has been widely used for decades, but essentially it is absolutely incorrect. “Septal deviation” is an inadequate term for the changes of the nasal septum form.
RESULTS. From the linguistic point of view, “accessory” means something (or someone) which (or who) helps someone or gives support (to something or someone) in some process. We recommend the use of the term “defect of the fontanel” instead of “accessory ostium”. The use of the term “septal deformity” (from Latin: de forma, meaning the change in the shape) is etymologically much more appropriate. Septal deformities appear in man in several, well defined shapes and, therefore, can be correctly classified. The classification contributes to the further scientific conversations regarding the clinical issues connected to the changes of the nasal septum form.
CONCLUSION. The usual term “accessory ostium” suggests almost a normal finding on the lateral nasal wall, but, on the contrary, it clearly signalizes that the respective maxillary sinus is chronically inflamed. The usual term “septal deviation” is not at all specific and only suggests that something is wrong with the position of the nasal septum. It does not at all imply any of the six well known types of septal deformities in man.
