Retrospective

143 patients with PTOD

Higher prevalence of parosmia and tendency to phantosmia in patients with medium overall brain damage Lower frequency of lesions in the right temporal lobe in patients with parosmia Lesions of the right OB were more frequent in patients with anosmia Higher frequency of left frontal lobe lesions in patients with phantosmia OBV was decreased in patients with PTOD Lesions at the level of the OB, olfactory tract, and gyrus rectus were associated with the results of the olfactory ERPs Correlation between OBVandOF Right OS correlated with OF OS was negatively correlated with age Abnormalities were identified in 4.6% 0.8% of patients had olfactory loss attributable to imaging findings The estimated cost per attributable abnormal finding was $325,000 USD
