Abstract

Sfenoidni sinus najvarijabilnija je šupljina ljudskog tijela. Unatoč tome što su u literaturi opisane brojne varijacije sfenoidnog sinusa gotovo je potpuno neistraženo ovisi li učestalost pneumatizacije drugih dijelova sfenoidne kosti i protruzija žilno-živčanih struktura o tipu pneumatizacije sinusa. Cilj istraživanja je odrediti učestalost pneumatizacije ala major, processusa pterygoideusa, planuma sphenoidalea, dorsuma sellae i clivusa te protruzija n.maxillarisa, n.canalis pterygoidei, n.opticusa, a.carotis interne i n.mandibularisa za sinuse pojedinih tipova pneumatizacije (conchalni, presellarni, sellarni, postsellarni). U istraživanju je korištena 51 lubanja koje su snimljene CBCT uređajem. Napravljen je novi sustav klasifikacije te su odnosi sinusa i žilno-živčanih struktura klasificirani u 5 kategorija. Pronađene su velike razlike između sinusa različitih tipova pneumatizacije. Učestalost pneumatizacije svih promatranih dijelova klinaste kosti kao i protruzija žilno-živčanih struktura značajno raste u nizu tipova sinusa: conchalni, presellarni, sellarni, postsellarni. Istraživanjem je dokazano kako se na osnovi tipa pneumatizacije može predvidjeti pružanje sinusa te odnosi sinusa s bliskim žilno-živčanim strukturama. Poznavanje navedenih činjenica može biti važno radi sprječavanja mogućih komplikacija tijekom kirurških zahvata te radi razumijevanja patogeneze procesa koji mogu imati ishodište u sfenoidnom sinusu.

Abstract (english)

Sphenoid sinus is the most variable cavity in the human body. The aim of the study has been to determine the frequency of pneumatization of greater wings, pterygoid process, planum sphenoidalae, dorsum sellae and clivus, as well as the protrusions of maxillary nerve, pterygoid nerve, optic nerve, internal carotid artery and mandibular nerve for the sinuses of certain types of pneumatization (conchal, presellar, sellar, postsellar). The total of 51 CBCT-recorded skulls has been used in the study. A new classification system has been suggested, so that the relations between sinuses and neurovascular structures have been classified into 5 categories. Big differences between sinuses of various types of pneumatization have been discovered. The frequency of pneumatization of all the analysed parts of the sphenoid bone and the protrusion of neurovascular structures significantly increases in a series of types: conchal, presellar, sellar, postsellar. The knowledge of the above-stated facts may be important for preventing potential complications in the course of operation and understanding the pathogenesis of processes that can result from sphenoid sinus.
