This test consists of two parts, consisting of the olfactory threshold of research and smell identification; the olfactory classification is performed by analyzing: (1) the combined score between the threshold test (butanol) and smell identification, which corresponds to the arithmetic mean of both scores. Thereafter, a combined score was obtained for each nasal cavity separately. (2) The Combined Score Index, which is the arithmetic mean of the combined scores of each nasal cavity. Thus, according to the combined score of the indexes obtained, the following values were considered for the classification of the olfactory status of each patient: 6.0–8.5: normosmia; 5.0–5.75: mild hyposmia; 4.0–4.75: moderate hyposmia; 2.0–3.75: severe hyposmia; and 0–1.75: anosmia. R, right; L, left; CS, combined score; FS, final score; SI, smell identification; BT, butanol threshold; NP, not performed.
