One-Sided Nasal Blockage and Bleeding: When Should It Be Investigated?

Frequently Asked Questions

What does this condition mean?

A deviated septum, enlarged turbinate, nasal-valve narrowing, inflammation, polyps, and crusting are common causes. Less often, a foreign body, inverted papilloma, vascular lesion, or tumour is responsible. Persistent one-sided obstruction therefore calls for a structured differential diagnosis.

Does it always mean a serious disease?

Alternating stuffiness can fit the normal nasal cycle; steadily worsening blockage on the same side is different. Recurrent bleeding, bloody or foul discharge, unilateral smell loss, facial pain or numbness, dental symptoms, a neck lump, or orbital symptoms accelerate assessment. Temporary relief with a decongestant does not establish the diagnosis.

How is it diagnosed?

History and anterior rhinoscopy are commonly followed by nasal endoscopy. Imaging is not routine for every blocked nose; CT and/or MRI is selected for a suspected mass, unilateral sinus disease, bony anatomy, or possible orbital or skull-base extension. Biopsy of a suspicious visible lesion is planned with vascular risk and imaging in mind.

How is treatment selected?

Treatment follows the cause: saline and appropriate nasal medicines for inflammation, bleeding control and moisturising for crusting, and selected surgery for septal or valve problems. A mass requires pathology-led multidisciplinary planning. A sensation of blockage alone is not enough to justify surgery.

What should I avoid doing at home?

Do not use decongestant sprays beyond the recommended period, insert sharp objects, or attempt cautery at home. Record which side is blocked, how long it has lasted, and whether bleeding occurs. During active bleeding, lean forward and apply uninterrupted pressure to the soft part of the nose.

When is urgent assessment needed?

Uncontrolled heavy bleeding, breathing difficulty, eye swelling or loss of vision, new facial numbness or weakness, severe headache, or neurological signs are emergencies. Arrange prompt ENT review for persistent unilateral blockage with recurrent bleeding or blood-stained discharge.
