Sinusitis is a relatively common otolaryngological disease. If sinusitis is cured after treatment, clinically it means that the symptoms have subsided; there is no nasal congestion, no purulent nasal discharge, normal sense of smell, and no headache, dizziness, or blood in the nasal discharge. However, individual differences in treatment outcomes do exist. During the treatment process, regular follow-up visits are necessary to observe the recovery status of the condition. Additionally, combining nasal endoscopy, routine blood tests, and sinus CT scans with the doctor's clinical experience can help determine whether the sinusitis has healed. However, some patients may experience a recurrence of symptoms after treatment.
