Paranasal sinuses:anatomic terminology and nomenclature

A consensus on the preferred modern usage of potentially confusing or ambiguous terms in sinus anatomy and nomenclature is described. These terms are intended to provide clear communication among otorhinolaryngologists and serve as a basis for discussion among anatomists. Terminology is in English and based on Latin nomenclature. An attempt has been made to reconcile or eliminate duplication, redundancy, and overlap in terminology that have arisen over the past century. A key concept is that the ethmoid complex is divided into anterior and posterior sections by the basal lamella of the middle turbinate.
