Gaining back what is lost: recovering the sense of smell in mild to moderate patients after COVID-19.

The purpose of our cohort study was to quantify olfactory deficits in COVID-19 patients using Sniffin' Sticks and a pre-post design to evaluate olfactory recovery. 30 adult patients with laboratory-confirmed mild to moderate forms of COVID-19 underwent a quantitative olfactory test performed with the Sniffin' Sticks Test (SST, Burghardt®, Wedel, Germany) considering olfactory threshold (T), odor discrimination (D) and odor identification (I). Results were presented as a composite TDI score (range 1-48) used to define functional anosmia (TDI ≤ 16.5), hyposmia (16.5
