Non-infective Non-allergic Rhintis Dr. Vishal Sharma

1. Vasomotor rhinitis 2. Non-Allergic Rhinitis with Eosinophilia Syndrome 3. Occupational Irritant: flour, animal, wood, latex, paint 4. Rhinitis medicamentosa: decongestant nose drops 5. Drug-induced: propranolol, O.C.P., amytriptilline 6. Endocrine: hypothyroid, pregnancy, menstruation 7. Addiction: alcohol, tobacco 8. Non-airflow: tracheostomy, laryngectomy 9. Miscellaneous: honeymoon / emotional

Autonomic Innervation of Nose Deep petrosal nerve (Symp) + greater superficial petrosal nerve (Para-symp)  vidian nerve  pterygo-palatine ganglion  nasal glands Sympathetic stimulation  vasoconstriction + ed nasal secretions Para-sympathetic stimulation  vasodilatation + ed nasal secretions

Vasomotor Rhinitis

Pathogenesis Caused by over activity of para-sympathetic nervous system leading to: nasal congestion (due to nasal vasodilatation) nasal block (due to nasal vasodilatation) watery rhinorrhoea (due to ed nasal secretion)

Trigger Factors 1. emotional stress (hypothalamus controls autonomic nervous system) 2. sudden change in temperature 3. humidity 4. blasts of cold air 5. dust 6. smoking & traffic fumes

Clinical Features Symptoms are perennial Nasal block (Blockers) Profuse watery rhinorrhoea (Runners) Paroxysmal early morning sneezing Post nasal drip Turbinates congested & hypertrophied

Diagnostic Nasal Endoscopy

Sequelae & Differential Diagnosis  Nasal polyp  Hypertrophic rhinitis  Sinusitis Differential diagnosis Allergic rhinitis Non-allergic rhinitis with eosinophilia syndrome Rhinitis medicamentosa

Treatment of Vasomotor Rhinitis

General Measures  Sleep with head end elevated by 300  Sleep + work in a cool environment (not cold)  Keep body warm  Regular exercise program to improve vasomotor tone  Avoidance of trigger factors

Medical Treatment Ipratropium bromide spray (0.03%) Intra-turbinal injection of Botulinum toxin Steroid spray Topical Cromolyn sodium (prophylaxis only) Anti-histamines Nasal decongestant

Topical nasal decongestant Drug Sneeze Rhinorrhoea Nasal block Nose itch ed smell Antihistamine +++ ++ + Steroid spray Cromoglycate Topical nasal decongestant ++++ Ipratropium

Antihistamines Systemic: Cetirizine: 10 mg OD Fexofenadine: 120 mg OD Loratidine: 10 mg OD Levocetrizine: 5 mg OD Desloratidine: 5 mg OD Topical: Azelastine spray (0.1%): 1-2 puff BD

Nasal Decongestants

Ipratropium nasal spray Has anti-cholinergic action

Botulinum Toxin Injection Inhibits release of Acetylcholine   rhinorrhoea

Corticosteroid sprays Strength / puff Acute attack dose Maintenance dose Beclomethasone 50 g 2 puffs BD 1 puff OD Budesonide 64 g 2 puffs OD-BD Fluticasone Mometasone

Corticosteroid nasal spray

Sodium Cromoglycate

Surgical Treatment Measures which reduce size of nasal turbinates to relieve nasal obstruction Sectioning parasympathetic secreto-motor fibers of nose (vidian neurectomy) to relieve excessive rhinorrhoea

Inferior Turbinate Surgeries

Surgeries for mucosal hypertrophy On surface:  Electrocautery  Laser vaporization Intramural:  Electrocautery (SMD)  Cryotherapy  Radiofrequency ablation Surgeries for bony hypertrophy  Submucous resection of inferior concha Surgeries for mucosal + bony hypertrophy  Partial turbinectomy  Total turbinectomy  Inferior turbinoplasty (neo-turbinate)

Hypertrophied Turbinate

Submucosal diathermy

Radiofrequency ablation

Partial Turbinectomy

Total (Radical) Turbinectomy

Inferior Turbinoplasty

Vidian Neurectomy Trans-antral approach (Golding Wood) Trans-septal approach

Rhinitis Medicamentosa

Introduction Rebound nasal congestion due to use of intranasal decongestants for > 7 days With prolonged use, tachyphylaxis occurs, resulting in need for more frequent doses & shorter duration of action of these drugs Nasal medications containing benzalkonium chloride cause more rebound congestion

Offending drugs 1. Oxymetazoline 2. Xylometazoline These drugs contract smooth muscle of venous erectile tissue, present in nasal turbinates, causing mucosal shrinkage & decreasing airway resistance

Pathogenesis

Clinical Features 1. Chronic nasal block requiring increased dose & frequency of topical decongestants 2. Watery rhinorrhoea usually absent, seen only in co-existing allergic or vasomotor rhinitis 3. Nasal mucosa appears hyperemic, granular & boggy in early stages 4. Later, it appears pale & anemic

Treatment Immediate withdrawal of topical decongestant Substitute with systemic nasal decongestants Nasal corticosteroid sprays Oral corticosteroids (for severe cases only) Rhinostat system Patient Education: Avoid topical decongestant use for > 7 days

Treatment For patients unable to stop topical decongestant immediately, stop nose drops in more patent nasal cavity & use it in other cavity for < 7 days Systemic decongestants used to relieve nasal block as pt is weaned off topical decongestants Phenylephrine & pseudoephedrine are used Corticosteroid spray used to  local inflammation

Rhinostat System Consists of 2 bottles.  First contains pt’s nasal decongestant spray, second has saline solution. Two solutions precisely combined for dosage dilution @ 15% / day. Dosage titration allows gradual withdrawal from decongestants while maintaining nasal inspiratory flow. Takes 3-6 weeks days for complete withdrawal.
