The posterior system is therefore made up of the cells that form the posterior ethmoid and the sphenoid sinus. The basal lamella of the middle turbinate is the boundary between the anterior and posterior ethmoid sinuses. The sphenoid sinus has an irregularly cubic shape. In its lateral wall it is possible to appreciate two protuberances of considerable clinical importance. These are produced by the optical nerve and the internal carotid artery. Before ESS, computerized tomography scans are performed to assess sinonasal anatomy and disease pattern. To enter the posterior ethmoidal complex, the oblique basal lamella of the middle turbinate needs to be breached or removed. The sphenoid sinus can be opened through both a transnasal and a transethmoidal approach.

Abstract
The posterior system is therefore made up of the cells that form the posterior ethmoid and the sphenoid sinus. The basal lamella of the middle turbinate is the boundary between the anterior and posterior ethmoid sinuses. The sphenoid sinus has an irregularly cubic shape. In its lateral wall it is possible to appreciate two protuberances of considerable clinical importance. These are produced by the optical nerve and the internal carotid artery. Before ESS, computerized tomography scans are performed to assess sinonasal anatomy and disease pattern. To enter the posterior ethmoidal complex, the oblique basal lamella of the middle turbinate needs to be breached or removed. The sphenoid sinus can be opened through both a transnasal and a transethmoidal approach.Pubblicazioni consigliate
