Abstract

Objective: This doctoral thesis is a retrospective-prospective anatomic-radiologic study with an objective to research anatomic variations of sphenoid sinus shown by computed tomography. ----- Patients and methods: The study included 122 subjects, 58 men and 64 women. All patients underwent computed tomography examination during the usual procedures for suspected paranasal sinus diseases. The aim was to investigate the spreading of the sphenoid sinus extensions into the parts of the sphenoid bone; the anterior clinoid process; the greater wing and into the pterigoid process of sphenoid bone, as the protrusion of the optic nerve, maxillary nerve and the vidian nerve into the sphenoid sinus. Dehiscence bony partitions that can be found between nerve structures and sphenoid sinus were also researched. ----- Results: ACP pneumatization, GWS and the PP was found in 39 (31.97%), 48 (33.34%) and 62 (50.82%) patients respectively. VN protrusion, MN and ON was found in 61 (50%), 44 (56.07%) and 33 (27.05%) patients respectively and dehiscence bone septum between these neural structures and sphenoid sinus in 54 (44.26%) , 29 (23.77%) and 24 (19.67%) patients respectively. ----- Conclusion: Sphenoid sinus is highly variable. Anatomic variations of sphenoid sinus are common. Computed tomography, especially, MSCT in particular is the method of choice in the detection of anatomic variations of sphenoid sinus and is increasingly becoming the gold standard for evaluating planned preoperational endonasal, endovascular procedures on the sinuses, as also before neuro microsurgery on structures that surround the sinus, especially on the Sella turcica transsphenoid approach for removal of pituitary adenomas.

Abstract in Croatian

Cilj: Ova doktorska disertacija je retrospektivno-prospektivna anatomsko-radiološka studija sa ciljem istraživanja anatomskih varijacija sfenoidnog sinusa prikazanih kompjutoriziranom tomografijom. ----- Ispitanici i metode: U istraživanje su uključena 122 ispitanika, 58 muškaraca i 64 žene. Kod svih ispitanika učinjen je pregled kompjutoriziranom tomografijom i to tijekom uobičajenih postupaka zbog sumnje na bolesti paranazalnih sinusa. Istraženo je širenje produžetaka sfenoidnog sinusa u dijelove klinaste kosti; u prednje klinoidne nastavke, velika krila i pterigoidne nastavke klinaste kosti, te protruzije optičkog živca, maksilarnog živca i Vidijevog živca u sfenoidni sinus. Ujedno su istražene dehiscijencije koštanih pregrada koje se nalaze između navedenih živčanih struktura i sfenoidnog sinusa. ----- Rezultati: Pneumatizacija ACP, GWS i PP nađena je u 39 (31,97%), 48 (33,34%) i 62 (50,82%) ispitanika. Protruzija VN, MN i ON nađena je u 61 (50%), 44 (56,07%) i 33 (27,05%) ispitanika te dehiscijencija koštanih pregrada između navedenih živčanih struktura i sfenoidnog sinusa u 54 (44,26%), 29 (23,77%) i 24 (19,67%) ispitanika. ----- Zaključak: Sfenoidni sinus je varijabilne građe. Anatomske varijacije sfenoidnog sinusa nisu rijetkost. Kompjutorizirana tomografija, posebice, MSCT je metoda izbora u detekciji anatomskih varijacija sfenoidnog sinusa i sve više postaje zlatni standard u preoperacijskoj evaluaciji planiranih endonazalnih i endvaskularnih zahvata na samom sinusu, kao i prije neuromikrokirurških zahvata na strukturama koje okružuju sinus.
