Thanks for contacting HCM
CT Scan report
1. DNS to right with septal spur means Deviated nasal septum (nasal septum - a partition of bone and cartilage between the nasal cavities).
2.right maxillary, frontal, anterior ethmoidal and sphenoidal sinusitis means inflammation of sinuses ( sinus is a air filled cavity within a bone in normal condition but in your case either fluid filled or fungal filled cavity)
3.The right ostio-meatal unit is blocked means draining area of these sinuses is blocked.
