![]() ![]() The olfactory bulbs and tracts are located under the olfactory sulcus on the lower surface of the frontal lobe. The olfactory nerves traverse the cribriform plate and form olfactory bulbs intracranially, and the olfactory tracts connect the olfactory bulbs to the brain. 3 The olfactory system consists of primary olfactory nerves in the nasal cavity, the olfactory bulb, olfactory tract, and connections extending to the central nervous system. Clinically, these abnormalities present as olfactory auras or olfactory performance deficits such as odor detection impairment. 2 Olfactory abnormalities in epilepsy are well documented. 1 The incidence of epilepsy in children varies from 41 to 187 per 100,000, with approximately 30,000 children being diagnosed with epilepsy every year. The decrease in OBV in children with epilepsy reflects not only the olfactory function of OBV but also the destructive effect of childhood epilepsy on the nervous system.Įpilepsy is a chronic neurological disease that affects people of all ages.In this study, OBV values of pediatric patients with epilepsy were decreased. A quantitative analysis of the olfactory system can be reliably undertaken using magnetic resonance imaging.To date, studies on the olfactory system in epilepsy have focused on adults. There is a correlation between decreased olfactory bulb volume (OBV) and the presence of some neurodegenerative diseases, such as dementia and Alzheimer disease.Keywords: Epilepsy, magnetic resonance imaging, olfactory bulb, olfactory sulcus, olfactory tract OBV was significantly reduced in the children with epilepsy compared with the control group ( P 0.05). The OBV, OTL, and OSD values were compared between the epilepsy group, subgroups, and controls. Subsequently, OBV and OSD were measured from the coronal section and OTL from the sagittal section. The patients with epilepsy were divided into groups according to the type of disease and treatment method. METHODSĬranial MRI images of 36 patients with epilepsy and 108 controls (3–17 years) were evaluated. Our aim was to determine the presence of olfactory dysfunction in children with epilepsy and demonstrate the effects of the epilepsy type and treatment on olfactory function in these patients. In this study, we compared the OBV, OTL, and OSD values of children with epilepsy and those of healthy children (controls) of similar age. Studies have demonstrated that olfactory bulb volume (OBV), olfactory tract length (OTL), and olfactory sulcus depth (OSD) can be reliably evaluated using magnetic resonance imaging (MRI). Olfactory dysfunction is a well-known complication in epilepsy. ![]()
