EN4.25 | Vasomotor Rhinitis — Summary & Reflection

KEY TAKEAWAYS

Vasomotor rhinitis is a chronic non-allergic, non-infectious nasal condition caused by autonomic dysregulation of the nasal mucosal vasculature and glands — excessive parasympathetic reactivity to physical and chemical non-allergic triggers. Symptoms: perennial bilateral obstruction and rhinorrhoea WITHOUT sneezing, nasal itch, or ocular symptoms; triggers include cold air, perfumes, smoke, alcohol, spicy food, emotional stress. Allergy tests (SPT, sIgE) are NEGATIVE — this is non-negotiable. Nasal smear shows no eosinophilia (contrast with NARES). Subtypes: rhinorrhoea-dominant (treat with intranasal ipratropium bromide — anticholinergic) and obstruction-dominant (treat with intranasal corticosteroids). Antihistamines are not effective (no histamine role). Gustatory rhinitis is a subtype triggered by hot/spicy food — treat with pre-meal intranasal ipratropium. Surgical options for refractory disease: inferior turbinoplasty (obstruction) or vidian neurectomy (refractory rhinorrhoea — rarely used; risk of dry eye).

REFLECT

Think about a patient who has been suffering from nasal symptoms for years, has had multiple negative allergy tests, has tried antihistamines without benefit, and has been told repeatedly that 'nothing is wrong.' What would it mean to that patient to finally receive a correct diagnosis of vasomotor rhinitis — not an allergy, not an infection, but a disorder of the nose's autonomic control — and to be given a specific, targeted treatment? The lesson of vasomotor rhinitis is that a negative test result (negative SPT) is itself a positive diagnostic finding when interpreted in the right clinical context. Do not treat a negative allergy test as the end of the diagnostic journey.
