Why can’t I get any smell?

Nasal and sinus diseases are the most common diseases causing problems in the sense of smell. Allergic rhinitis, nasal polyps, sinusitis, advanced nasal bone and cartilage curvature, nasal trauma, concha bullosa and nasal fissure in children are the common causes of nasal disorders. In addition, upper respiratory viral infections and head traumas are among the most common causes of smell-sense disorders.
