A blow to the nose leaves it crooked and blocked — fracture; closed reduction within days. Nasal fracture (commonest facial fracture — direct blow): deformity, epistaxis, periorbital ecchymosis; reduce closed within 7–10 days before bones set — septal hematoma (drain urgently — cartilage necrosis risk) must be excluded. DNS (deviated septum — developmental/trauma: unilateral blockage, epistaxis, sinusitis; septoplasty if symptomatic). Tumors — benign (inverted papilloma — unilateral polyp-like, malignant potential) vs malignant (squamous carcinoma — unilateral bloody discharge, pain, biopsy). The crooked nose is mechanical — straighten before it sets.
