Journal Title: International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 1
Abstract
Introduction: Sinusitis is one of the commonly diagnosed conditions made in the department of Oto-Rhino-Laryngology. Functional endoscopic Sinus Surgery (FESS) is a minimally invasive technique employed in the treatment of sinusitis. iatrogenic trauma to the skull base particularly the lateral lamella of the cribriform plate is a well know complication which leads to cerebrospinal fluid leakage and anterior ethmoidal artery injury. Hence it is essential for the surgeon to be aware of the variations in the ethmoidal roof and olfactory fossa pre-operatively in order to prevent such complications. In addition to delineating the variations we also compare in our study with different races to find any difference. Material and methods: The study was conducted on 500 patients from the district of Dakshin Karnataka (South Karnataka who underwent Computed Tomography (CT) of the Paranasal Sinus (PNS) for symptoms of sinusitis. The study was conducted in the department of Radio-Diagnosis of Father Muller Medical College Hospital, Mangalore, Karnataka. Results: Most common amongst the male population was TYPE I constituting 331 cases (53.3% of type I cases) with left predominance (163 cases) whereas amongst the female population the most common type was that of type II constituting 233 cases (61.6% of type II cases) (Table 2) with right predominance (120 cases). Type III had only 2 cases in our study which was detected in the male population with left side predominance. Conclusion: In conclusion, our study states that Keros Type 1 olfactory fossa in more common in the sample population in Dakshin Karnataka and the least common in Type III which is in agreement with a similar study performed in South India. Type I is more common Is males and Type II more common in females.
