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
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
Sequelae & Differential Diagnosis Sequelae Nasal polyp Hypertrophic rhinitis Sinusitis Differential diagnosis • Allergic rhinitis • Non-allergic rhinitis with eosinophilia syndrome • Rhinitis medicamentosa
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
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 Systemic decongestants Phenylephrine Pseudoephedrine Topical decongestants Xylometazoline Oxymetazoline Saline
Anti-cold preparations PsE = Pseudoephedrine; PhE = Phenylephrine
Topical Decongestants • Oxymetazoline 0.05 %: 2-3 drops BD (NASIVION) • Oxymetazoline 0.025 %: 2 drops BD (NASIVION-P) • Xylometazoline 0.1 %: 3 drops TID (OTRIVIN) • Xylometazoline 0.05 %: 2 drops BD (OTRIVIN-P) • Saline 2 %: 3 drops TID • Saline 0.67 %: 2 drops BD (NASIVION-S)
Ipratropium nasal spray Has anti-cholinergic action
Botulinum Toxin Injection Inhibits release of Acetylcholine rhinorrhoea
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
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)
Vidian Neurectomy • Trans-antral approach (Golding Wood) • Trans-septal approach
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
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.
