The subjective and objective symptoms of nasal obstruction had improved 1 year after septoplasty. A significant correlation between VAS scores and nasal resistance in the narrow side of the nose was found before surgery. The subjective and objective measurements of nasal obstruction lacked significant correlation postoperatively.

Objective: To compare the effects of botulinum toxin and steroid septal injections in treating allergic rhinitis (AR) by evaluating improvements in the rhinitis control assessment test (RCAT), visual analog scale (VAS), nasal obstruction symptom evaluation (NOSE) scores, and active anterior rhinomanometry (RMM) measurements.
