What symptom may be observed in patients with ani-allergic rhinitis?

In patients with allergic rhinitis, a distinctive feature that may be observed is the presence of a transverse nasal crease. This crease, often referred to as the "allergic salute," results from the habitual action of rubbing the nose upward, which many individuals with allergic rhinitis tend to do in response to itching or irritation. Over time, this repetitive motion can lead to a persistent line or crease across the bridge of the nose.

Intense nasal congestion, while it can be a symptom associated with allergic rhinitis, is more of a subjective experience rather than a physical sign like the transverse nasal crease. Incision cuts in the nasal mucosa and painless nasal ulcerations are not characteristic of allergic rhinitis and are more commonly associated with other conditions or injuries. Therefore, the transverse nasal crease serves as a visible and recognizable indicator of allergic rhinitis, linking both the symptoms and the behavioral response to the condition.
