In brief: Obstruction

Diminished or altered ense of smell is likely due to poor airflow to the roof of the nose where the nerve endings for smell are located.
A thorough nasal endoscopy will check for nasal polyps ( which are usually due to allergies). If the endoscopy is normal, then a ct scan may be helpful in ensuring no other abnormalities in the skull base that can alter sense of smell.
