“…[7,9,10,25] The area of the entry of AEA through the lateral lamella into the olfactory fossa is considered the thinnest and at risk of injury causing CSF leak. [7][8][9] In our study we have observed that low or flattened contour of ethmoidal fovea as well as asymmetries between the sides in respect to height and contour of ethmoidal fovea were most commonly associated with Keros type I.…”

“…Gauba et al ascertained the prevalence of Keros types 1, 2 and 3 as 34%, 28% and 38%, respectively. [28] Adeel et al, however, give the corresponding values as 29.8%, 48.7% and 21.4%. [29] The lamina cribrosa had an average depth of 5.35mm in their study.…”

The relationship between superior attachment of the uncinate process of the ethmoid and varying paranasal sinus anatomy: an analysis using computerised tomography Abstract Objective: The purpose of this research was to examine how attachment of the uncinate process superiorly (SAUP) relates to possession of an agger nasi cell, pneumatisation of the middle turbinate and the measurements of the base of the skull anteriorly. The study was carried out using computerised tomography (CT). Methods:The study involved CT imaging captured from 727 individuals with persistent sinusitis-1454 images in total, featuring coronal section of the paranasal sinus. The frequency of SAUP, existence of an agger nasi cell, pneumatisation of the middle turbinate and how high the lamella measured laterally, were all noted. Landsberg and Friedman's classification scheme for SAUP was utilised. Statistical analysis used the chisquared test.Results: In 1.65% of cases, SAUP was not identifiable.With regard to class of SAUP, the most frequent was type 2, then, in descending order of frequency, types 1, 4, 3, 5 and 6. The frequencies noted were 27.6%, 19.8%, 15.4%, 14.5%, 12.0% and 9.0%, respectively. An agger nasi cell was visualised in 894 images (61.07%). There was pneumatisation of the middle turbinate in 395 images (27.17%). The lamina cribrosa measured 5.58mm on average. Conclusion: There were significant correlations between the type of SAUP and the existence of agger nasi cells or of concha bullosa. However, the type of SAUP was not statistically significant in predicting the height of the lamina cribrosa.The relationship between superior attachment of the uncinate process of the ethmoid and varying paranasal sinus anatomy:

“…5C). 8,26 Although present in only approximately 1% of the population, recognition of this anatomic variant is crucial; a sinus surgeon may want to be much more conservative in cases with this skull base configuration. Preoperative CT evaluation should note any asymmetry in Keros configuration between the 2 skull base sides because this may also lead to complications when not recognized.…”
