Evaluation of the Keros Classification of Olfactory Fossa by CT Scan in Qassim Region [PDF]

Cureus, 2022
Objective Endoscopic sinus surgery (ESS) is now the most often utilized surgical procedure for treating chronic sinonasal disorders. Therefore, anatomical knowledge of its variations is required to avoid serious postoperative complications. Thus, careful preoperative examination for patients with a paranasal sinus CT scan is necessary.

Analysis of the Correlation of the Lamina Papyracea-to-Midline Distance with the Location of Anterior Ethmoidal Artery and Keros Classification [PDF]

Indian Journal of Otolaryngology and Head and Neck Surgery, 2023
The aim of the study was to investigate the relations between anatomical structures that are susceptible to inadvertent injuries during the surgery using preoperative computed tomography (CT) scans. 153 CT scans were reviewed and the distance from the lamina papyracea (LP) to the midline and the distance of the anterior ethmoidal artery (AEA) to the ...

Assessment of ethmoid roof and olfactory fossa variations using Keros classification in a tertiary care hospital

The Egyptian Journal of Otolaryngology, 2022
Background Functional endoscopic sinus surgery is a common surgery done in otorhinolaryngology, but it is also riddled with complications. The most dangerous complication is the injury to the skull base leading to cerebrospinal fluid leak, meningitis or ...

Anatomical Variation of the Olfactory Fossa According to Keros and Yenigun Classifications in Karachi, Pakistan [PDF]

Cureus
The goal of our research is to assess the olfactory fossa anatomical variation through Keros and Yenigun classification by computed tomography (CT) scan of paranasal sinuses (PNS), as in order for surgeons to prevent major complications, they must be familiar with its variations in anatomy during functional endoscopic sinus surgery (FESS) related to ...

Comprehensive radiological assessment of ethmoid skull-base anatomy: beyond the Keros classification. [PDF]

Ann Med Surg (Lond)
The Keros classification has been the traditional standard for stratifying olfactory fossa depth and predicting skull-base risk during endoscopic sinus surgery (ESS). However, accumulating evidence from multicenter CT studies across different populations demonstrates that Keros type alone does not correlate ...

Evaluating the Olfactory Fossa Depth and KEROS Classification in Kashmiri Population

IJFMR - International Journal For Multidisciplinary Research, 2023
Background: KEROS classification is a means of classifying the depth of the olfactory fossa The olfactory fossa is shallow depression in the anterior cranial fossa whose floor is formed by medial lamella of cribriform plate located within ethmoid bone, lateral boundary by lateral lamella which is a thin plate like bone and is susceptible to injury ...

Multidetector Computed Tomography Used in Evaluation of Olfactory Fossa Depth in a Tertiary Hospital in Eastern Region of Nepal: A Descriptive Cross-sectional Study [PDF]

Journal of Nepal Medical Association
Introduction: Olfactory fossa (OF) is a depression in most infero-medial portion of anterior cranial fossa formed by cribriform plate, crista galli and lateral lamella of cribriform plate (LLCP).

Computed tomography assessment of the ethmoid roof based on Keros classification in Iraqi patients undergoing functional endoscopic sinus surgery

Journal of Ideas in Health, 2021
Background: Among the most popular methods employed to classify the depth of the olfactory fossa is Keros classification. This study aims to assess Keros classification of the ethmoid roof, any possible association between Keros types and gender, and the
