<bold>OBJECTIVE.</bold> We investigated the relationship between Lund-Mackay scale, olfactory bulb depth and width, and Keros classification in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
<bold>MATERIAL AND METHODS.</bold> In this retrospective study, paranasal sinus computed tomography (PNSCT) images of 47 patients with CRSwNP and 47 healthy subjects (control) were evaluated. In the CRSwNP group, PNSCT scans were assessed based on Lund-Mackay scale. In both groups, olfactory fossae (OF) depth and width, and Keros classification were evaluated.
<bold>RESULTS.</bold> The total Lund-Mackay score was 17.1±5.9. There were no significant differences between OF depth and width values of the nasal polyps group and control group. For both groups, Type II Keros was the most detected type; secondly, Keros type I and rarely Keros type III were detected. There was no significant correlation between Lund-Mackay score (All items and total score) and OF depth and width, and Keros type. There were negative correlations between ipsilateral OF depth and width (p&lt;0.05), whereas there were positive correlations between contralateral OF depth and width (p>0.05). Keros type was positively correlated between ipsilateral and contralateral OF depth and Keros type (p&lt;0.05). In older patients, left OF depth and Keros type decreased (p&lt;0.05).

OBJECTIVE. We investigated the relationship between Lund-Mackay scale, olfactory bulb depth and width, and Keros classification in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
MATERIAL AND METHODS. In this retrospective study, paranasal sinus computed tomography (PNSCT) images of 47 patients with CRSwNP and 47 healthy subjects (control) were evaluated. In the CRSwNP group, PNSCT scans were assessed based on Lund-Mackay scale. In both groups, olfactory fossae (OF) depth and width, and Keros classification were evaluated.
RESULTS. The total Lund-Mackay score was 17.1±5.9. There were no significant differences between OF depth and width values of the nasal polyps group and control group. For both groups, Type II Keros was the most detected type; secondly, Keros type I and rarely Keros type III were detected. There was no significant correlation between Lund-Mackay score (All items and total score) and OF depth and width, and Keros type. There were negative correlations between ipsilateral OF depth and width (p<0.05), whereas there were positive correlations between contralateral OF depth and width (p>0.05). Keros type was positively correlated between ipsilateral and contralateral OF depth and Keros type (p<0.05). In older patients, left OF depth and Keros type decreased (p<0.05).
CONCLUSION. As a conclusion, there was no correlation between Lund-Mackay score and olfactory fossa dimensions (depth and width). When considering age, one could notice that Keros type decreased in older patients.
