Where is crista galli located
SCG minimum and maximum dimensions were: width; 2,,9 mm, height; 7,,2 mm, anterior-posterior diameter; 6,,3 mm, respectively. In our study, SCG incidence was found 4. It is known that the developmental process of paranasal sinuses is almost completed after years of age. Due to these reasons, the frequency of anatomic variation increases after these ages mentioned above.
In the study of Som et al. However, they did not observe SCG in the group with yeas of age Som et al. Palabiyik the incidence of SCG in pediatric grups was found to be 1. The different ratios of SCG found in the literature regarding the anatomic variations may be due to the differences of the evaluation of the data, the sample size, the analysis of the methods and the anatomic definition of the terms in the study.
According to us that racial, sex and agerelated differences may also affect the results. Moreover, it is important that the images are evaluated by a radiologist. In our study, all images were evaluated by both radiologist and anatomy specialist. The crista galli is an important surgical boundary for the endoscopic transcribriform approach Lee et al.
Cobzeanu et al. In our study, we did not make a typing of the localization of Crista galli. Because of the connection of SCG with frontal sinus and frontal recessus, the researchers emphasized its important role in the formation of chronic sinusitis and mucosel.
Partial or complete opacification on CT scan of the pneumatized crista galli was found in Socher et al. The researchers noticed that SCG may also become infected in the cases with chronic rhinosinusitis. They demonstrated that the patients who did not respond to the drug therapy could be treated safely and effectively with endoscopic sinus surgery.
In our study, chronic rhinosinusitis was found in most of the cases. Finally, SCG is the sinonasal anatomic variations in the ethmoid bone. In our study, sinus crista galli was found at low rates in adult and pediatric age group. However; significant relationship was found between these variations and sinusitis.
The localizations and dimensions of SCG is directly porportional to the paranasal sinus infections. The identification of these variations by radiologists is very critical since it may help diagnosing chronic and undetermined sinusitis and also an important detail for the surgeon in endoscopic sinus surgery approach.
