Postinfectious olfactory loss: A retrospective study on 791 patients
Abstract
Objectives/Hypothesis: Postinfectious olfactory loss is among the most common causes of olfactory impairment and has substantial negative impact on patients' quality of life. Recovery rates have been shown to spontaneously improve in most of patients, usually within 2 to 3 years. However, existing studies are limited by small sample sizes and short follow‐up. We aimed to assess the prognostic factors for recovery in a large sample of 791 patients with postinfectious olfactory disorders. Study Design: Retrospective cohort. Methods: We performed a retrospective analysis of 791 patients with postinfectious olfactory loss. Olfactory functions were assessed using the Sniffin' Sticks test at the first and final visits (mean follow‐up = 1.94 years). Results: Smell test scores improved over time. In particular, patient's age and the odor threshold (T), odor discrimination (D), and odor identification (I) (TDI) score at first visit were significant predictors of the extent of change. The percentage of anosmic and hyposmic patients exhibiting clinically significant improvement was 46% and 35%, respectively. Conclusions: This study provides new evidence within the postinfectious olfactory loss literature, shedding light on the prognostic factors and showing that recovery of olfactory function is very frequent, even many years after the infection. Level of Evidence: 4. Laryngoscope, 128:10–15, 2018

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
