Sažetak
Sphenoid sinus is closely related to the adjacent neurovascular structures. According to the literature, a big difference in the incidence of protrusions of these structures was described. Moreover, each author used his/her own classification, so the measured data were incomparable. Therefore, unique classification of aforementioned protrusions is indispensable. In this study we explored the incidence and relation between sphenoid sinus and neurovascular structures. New classification of these relationships was proposed. The study was performed on 51 skulls (=102 sinuses) using Cone Beam Computerized Tomography. We investigated interrelation between maxillary nerve, pterygoid nerve, optic nerve, internal carotid artery, mandibular nerve and sphenoid sinus. They were classified into five categories based on protrusion of each structure: 0 (without close relationship), T (touches, but no protrusion), P1 (protrusion < 25%), P2 (protrusion between 25% and 50%) and P3 (protrusion > 50%). Incidence of position and relationship regarding to sphenoid sinus for each of five structures was: A) maxillary nerve: 0=58.8%, T=21.6%, P1=13.7%, P2=2.9% and P3=2.9% ; B) pterygoid nerve: 0=45.1%, T=19.6%, P1=15.7%, P2=2% and P3=17.7% ; C) optic nerve: 0=43.8%, T=29.5%, P1=12.4%, P2=10.5% and P3=3.8 % ; D) internal carotid artery: 0=56.9%, T=7.3%, P1=18.3%, P2=7.3% and P3=10.1% ; E) mandibular nerve: 0=95.1% and T=4.9%. Relationships between sphenoid sinus and surrounding neurovascular structures were highly variable (except mandibular nerve). Employing the new classification, level of protrusions was described in details. Knowledge of these anatomic variations is essential for improvement of surgical procedures and for the better understanding of the pathological processes that can occur in the sphenoid sinus.
