“…However, in Keros I, surgery may be safer to perform. [5][6][7][8][9][10][11] Uncinectomy is the primary step of ESS. The attachment of the uncinate process can vary and should be analyzed before surgery.…”

“…If clinically suspected, diseases or variations can be examined using the HRCT evaluation, which showed the anatomical structures and their relationships to each other, anatomical variations, and pathologies. [6][7][8] Although, anatomical knowledge and experience reduces the chances of arising complications, ESS has been associated with some problematic symptoms; minor complications including bleeding, infection, crusting, synechiae, ostial stenosis, and recurrence of the disease;…”

Objective:The relationship between the cribriform plate and the uncinate process may be elaborated with the help of the Keros classification. The observations were analysed using high-resolution computed tomography (HRCT). Additionally, the relationship between the superior attachment of the uncinate process, the existence of concha bullosa, and the different types of ethmoid roofs were examined. Methods: Five-hundred and sixteen subjects complaining of sinonasal disorders between 2015 and 2016 were enrolled retrospectively at the Okmeydani Training and Research Hospital, Department of Otolaryngology. HRCT scans of 1-mm sections were obtained. Keros classification was used for the measurement of the depth of the olfactory fossa as follows: Keros I: 1-3 mm, Keros II: 3-7 mm, and Keros III: 7-16 mm. Results: Fifty-one point nine percentage of cases were of Keros type II, 27.7% of type III, and 20.3% of type I. In 82.4% of the reported cases, the uncinate process was attached to the lamina papyraceae, in 11% of the cases it was attached to the middle nasal turbinate, and in 6.4% cases to the skull base. A concha bullosa was observed in the right nasal cavity in 13.8% of the cases, in the left nasal cavity in 11% of the cases, and bilaterally in 16.3% of the cases. Variances observed in the Keros types were not statistically significant with respect to sex (p>0.05). Concha bullosa was significantly more frequently seen in females (53.1%) relative to males (p=0.001). Conclusion: Endoscopic sinus surgery (ESS) is the primary mode of treatment for chronic sinus diseases. In this procedure, a proper assessment of the vital structures is very important to avoid further complications. In the present study, it has been suggested that determining the depth of the ethmoid roof is necessary to avoid injuring the bony lamella, which can lead to cerebrospinal fluid rhinorrhea.

Objective: The aim of this study was to determine prevalence of paranasal sinuses anatomic variations on computed tomography (CT) scan. Method: We retrospectively searched our radiology database for 426 paranasal sinus CT scan findings. CT scans were evaluated in terms of agger nasi cell, haller cell, onodi cell, pradoxical middle concha, bullos middle concha, septal deviation and pterigoid pneumatisation etc. We searched the prevalence of paranasal sinüs variations. Results: There were 229 male (%53.7) and 197 female (%46.2) patients. The mean age of the patients was 28.9 ±7.4 with range of 16-66. In 382 (%89.6) of all cases had at least one anatomic variation. In 44 (%10.3) cases had no anatomic variation. The most common anatomic variation observed on CT scans was nasal septal deviation, which was presented by 204 cases (%47.8). Agger nasi cell was the scond most common variation (136 cases; %31.9) and than concha bullosa of the middle turbinate (110 cases; %25.8). Conclusion: Radiological evaluation of the paranasal sinuses and soft tissue pathologies of the sinus air cells as well as the anatomical variations should be investigated. Detection of these variations play an important role in reducing complications that may occur during the operation.AnahtarKelimeler: Paranazal sinüsler, anatomik varyasyon, bilgisayarlı tomografi.

“…11 In most cases, infection spread from the anterior ethmoid area and middle meatal region to secondarily affect the maxillary and frontal sinuses. 12 Antral washout does not address the critical area of the anterior ethmoid cells and middle meatus. This may explain why there is no significant advantage of antral washouts and medical treatment over medical treatment alone.…”
