“…The comparison of the frequency of the different type of Keros on the right & left sides in males and females indicate that Keros type II was found to be the most frequent in both genders on both sides. Our results are in accordance with a few other studies 1,8,23,24 who also reported the highest frequency of type II Keros on both sides in both genders. Elwany et al report a higher frequency of type II Keros on both sides in the male gender only.…”

“…However, our study reports the least frequency of type I Keros on both sides in both genders. For some studies type, I remain to be the second-highest on both the sides in both genders 23,24 , for others type I remains to be second highest in males only. 8,22 Such variation may be due to racial differences and also could be due to the fact that Keros classification is ambiguous in the ranges of 3-4mm and 7-8mm.…”

“…1 While some studies reported the lowest frequency of type III on both sides in both genders. [22][23][24] Our study shows Keros type III to be the second-highest. Considerable variation exists as far as the frequency of type I Keros is concerned.…”

Objective: Keros classification based assessment of olfactory fossa depth in different age groups of both genders using computerized tomography (CT) Methodology: Cross sectional study done at Ziauddin university, Clifton, Karachi. Sample size was 270 adults including 160 males & 110 females. The assessment of depth of Olfactory fossa was carried out by measuring the height of lateral lamella of cribriform plate on CT images. Result: Olfactory fossa of 270 patients from both sides of both genders were classified according to Keros classification. We found Type II to be the most frequent on both sides in both genders. No significant difference in olfactory fossa depth was found when compared in different age groups. Conclusion: The present study shows that vast majority of the population comes under Keros type II & type III thus emphasizing the need of pre-operative radiological assessment. Association of right & left olfactory fossa depth in different age groups was found to be insignificant.

“…Our study showed that the height of LLCP on right side was 3.331+/-5.010mm, whereas on le side, it was 2.845+/-1.084mm.This differs from other studies as most of the 10,[12][13][14][15][16][17][18][19][20][21][22] studies had LLCP of >4mm.…”

Introduction: Computed tomogram (CT) of nose and paranasal sinuses provides the detailed knowledge of depth of olfactory fossa as per Keros' classification, which is important in endoscopic sinus surgery. Objective: To analyze the types and frequency of depth of olfactory fossa in Nepalese population. Methodology: This was a longitudinal study conducted from 1 May to 30 August 2018. Coronal CT scans of nose and paranasal sinuses were taken for analysis of olfactory fossa depth. The landmarks like infraorbital foramen, point of articulation of medial ethmoidal roof with lateral lamella of cribriform plate (MERP) and lowest point on the cribriform plate (CP) were taken. The lateral lamella of cribriform plate (LLCP) was calculated by subtracting CP height from MERP height (MERP-CP = LLCP). Results: There were total 101 patients included. The distribution of age was 33.72 ± 15.15 years. The keros' type I was the most common (86.1%). Regarding the olfactory fossa depth, right side was deeper in male whereas in females, the left side was deeper, but overall right side was deeper in 52(51.5%) patients. Conclusions: Type I Keros' was the most common whereas type III Keros' was the least common. A deep olfactory fossa is more common on right.

Introduction: Functional endoscopic sinus surgery (FESS)has become most preferred procedure in treatment of diseases of the nose and paranasal sinuses.The purpose of this study is todiscuss the incidence of skull base injury during surgery and radiologically analyse the depth of the olfactory fossa and the length of the lateral lamella in a CT PNS scan using the Keros classification, to determine the age and gender distribution, and to discuss its significance in surgical practice. Methodology: The is a retrospective study which was conducted among 200 patients above 10 years of age who visited ENT department in the past one year and had undergone CT PNS scan in radiology in VMKVMCH, Salem for sinusitis, headache, sinonasal polyposis and deviated nasal septum and those undergoing surgery. Scans of patients with previous history of surgery or trauma to nose and PNS and congenital anomalies of face were excluded. The results correlated with surgical relevance in FESS. Results: There were about 17% in Keros classification I, 78% Keros classification II and 6% Keros classification III.
