    Anatomical Variations of Sphenoid Sinus in Patients with Sino-Nasal Complaints– A Study based on CT Scan
    (Society for Health Care & Research Development, 2021-12) Reeti, Raag; Akhtar, Md Jawed
    Background: Sphenoid sinus is variably pneumatized and may show septations. There are some very important structures present in its relation likeopticnerveandinternalcarotidartery.So,itbecomesimportanttoknowthepatternsofvariationsinpneumatizationandseptationofthesinus so as to avoid any inadvertent injury to these structures during Functional Endoscopic Sinus Surgeries. The Aim is to determine the anatomical variations of sphenoid sinus on CT scan. Subjects and Methods:It CL can be used for repair/reconstruction procedures. A better understanding of histological characteristics of injured ACL ligament will add further knowledtion. The data on radiological variations were summarized by routine descriptive statistics namely counts and percentages for categorical variables.Result: In 86% of the radiographs, sellar type of pneumatization was found followed by pre-sellar type (8%) and post sellar type (6.6%). Sphenoid sinus Septation was found as single septum in 82% and multiple septum in 18% cases. There was no statistically significant difference between males and females according as evident by the ‘p’ value of 0.879 for sphenoid sinus pneumatization and 0.833 for sphenoid sinus septation.Conclusion: The sellar type of pneumatization was found to be most common in the present study. Awareness of these variations will help the surgeon in his orientation during endoscopic sinus surgeries to avoid inadvertent injury.
