Abstract
The aim of the study is to compare the olfactory bulb volume (OBV) and olfactory sulcus depth (OSD) of patients with Hashimoto's Thyroiditis (HT) with 3T MRI measurements with the control group.
Material-method: Cranial MRI examination was performed in a total of 215 patients, 105 patients were in the HT group and 105 patients were in the control group. The patients were evaluated retrospectively. OBV and OSD measurements were calculated on the right and left sides on coronal T2W images.
Results: Patients mean age was 43.74 ± 12.4 years. The mean OBV was measured as 88.57 ± 8.4 mm3 in HT patients and 93.43 ± 8.3 mm3 in control patients. The mean OSD was 8.35 ± 0.69 mm in HT patients and 8.65 ± 0.66 in control patients. Left, right, mean OBV and OSD were significantly lower in HT patients than in the control group.
Conclusion: HT patients are under risk of decreased OBV and OSD, which can affect olfactory functions. This can affect the quality of life.
