1. DEFINITION

  • Hypertrophic rhinitis is a chronic inflammatory condition of the nasal mucosa

  • Characterized by:

    • Persistent hypertrophy of inferior (± middle) turbinates

    • Thickened nasal mucosa

    • Increased submucosal glands and venous sinusoids

  • Leads to chronic nasal obstruction that is not fully relieved by decongestants

2. TERMINOLOGY & CONCEPT CLARITY (EXAM FAVORITE)

  • Also referred to as:

    • Chronic hypertrophic rhinitis

  • Represents a late stage of chronic rhinitis

  • Differs from allergic rhinitis by:

    • Lack of predominant itching and sneezing

    • Structural hypertrophy rather than reversible edema

3. EPIDEMIOLOGY

  • Common in:

    • Adults

    • Urban populations

  • No strong sex predilection

  • Frequently associated with:

    • Long-standing nasal obstruction

    • Poor nasal hygiene

    • Environmental pollution

4. ETIOLOGY (VERY HIGH-YIELD)

4.1 CHRONIC INFLAMMATORY CAUSES

  • Long-standing rhinitis (allergic or infective)

  • Recurrent upper respiratory infections

  • Chronic sinusitis

4.2 MECHANICAL FACTORS

  • Deviated nasal septum (DNS)

    • Compensatory turbinate hypertrophy on opposite side

  • Nasal valve obstruction

  • Chronic mouth breathing

4.3 ENVIRONMENTAL FACTORS

  • Dust

  • Smoke

  • Air pollution

  • Occupational exposure (cement, chemicals)

4.4 DRUG-INDUCED

  • Prolonged use of topical nasal decongestants

  • Leads to chronic mucosal changes

5. PATHOGENESIS (CORE CONCEPT)

5.1 INITIAL STAGE

  • Repeated inflammation

  • Venous congestion of turbinate sinusoids

  • Reversible mucosal edema

5.2 PROGRESSIVE STAGE

  • Persistent inflammation

  • Increased fibroblast activity

  • Hyperplasia of:

    • Submucosal glands

    • Venous sinusoids

  • Thickened turbinate tissue

5.3 LATE STAGE

  • Irreversible turbinate hypertrophy

  • Poor response to vasoconstrictors

  • Fixed nasal obstruction

6. PATHOLOGY

6.1 GROSS FEATURES

  • Enlarged inferior turbinates

  • Congested, reddish nasal mucosa

  • Narrowed nasal airway

  • Mucoid discharge

6.2 MICROSCOPIC FEATURES

  • Thickened epithelium

  • Increased goblet cells

  • Dilated venous sinusoids

  • Submucosal gland hyperplasia

  • Fibrosis in advanced cases

7. CLINICAL FEATURES

7.1 SYMPTOMS

  • Chronic nasal obstruction (bilateral or alternating)

  • Mouth breathing

  • Hyponasal speech

  • Headache

  • Reduced smell (hyposmia)

  • Late stage:

    • Minimal or no shrinkage
      → indicates true hypertrophy

9. DIFFERENTIAL DIAGNOSIS

  • Allergic rhinitis

  • Vasomotor rhinitis

    • Rule out allergy

    • Identify associated infection

Tests

  • Complete blood count

  • Absolute eosinophil count (may be mildly raised if allergic component present)

11.2 NASAL SMEAR

  • Helps differentiate from allergic rhinitis

  • Findings:

    • Few or absent eosinophils

    • Predominantly neutrophils in infective cases

11.3 ENDOSCOPIC NASAL EXAMINATION

  • Shows:

    • Inferior turbinate hypertrophy

    • Degree of airway obstruction

    • Associated DNS

    • Middle meatal pathology

    • Chronic sinusitis suspected

    • Headache not explained clinically

  • CT findings:

    • Enlarged turbinates

    • Mucosal thickening

    • Associated sinus disease

12. DIAGNOSIS

  • Mainly clinical

  • Based on:

    • Chronic nasal obstruction

    • Inferior turbinate hypertrophy

    • Poor response to decongestants

  • Decongestant test helps confirm true hypertrophy

13. MANAGEMENT — GENERAL PRINCIPLES

  • Treat underlying cause

  • Medical therapy first

  • Surgery reserved for:

    • Failure of medical treatment

    • Fixed turbinate hypertrophy

  • Patient counseling is important:

    • Surgery improves airflow

    • Does not cure underlying rhinitis

14. MEDICAL MANAGEMENT (FIRST-LINE)

14.1 ALLERGEN & IRRITANT AVOIDANCE

  • Avoid dust, smoke, pollution

  • Treat occupational exposure

  • Correct nasal hygiene

14.2 INTRANASAL CORTICOSTEROIDS

  • Most effective medical therapy

  • Reduce:

    • Inflammation

    • Mucosal edema

Common Drugs

  • Fluticasone

  • Mometasone

  • Budesonide

Important

  • Best response in early disease

  • Limited benefit in advanced fibrotic hypertrophy

14.3 ANTIHISTAMINES

  • Useful if allergic component present

  • Second-generation preferred:

    • Loratadine

    • Cetirizine

    • Fexofenadine

14.4 DECONGESTANTS

  • Short-term use only

  • Avoid prolonged topical use

  • Prevent rhinitis medicamentosa

14.5 NASAL SALINE IRRIGATION

  • Improves mucociliary clearance

  • Reduces secretions

  • Adjunctive therapy

15. FAILURE OF MEDICAL THERAPY

Indicators

  • Persistent nasal obstruction > 3 months

  • Poor response to intranasal steroids

  • Fixed turbinate enlargement

  • Associated sleep disturbance or sinusitis

16. SURGICAL MANAGEMENT (VERY HIGH-YIELD)

16.1 PRINCIPLES OF SURGERY

  • Reduce turbinate size

  • Preserve mucosa

  • Maintain nasal physiology

16.2 SURGICAL OPTIONS

A. SUBMUCOUS DIATHERMY (SMD)

  • Commonly used

  • Coagulates submucosal tissue

  • Causes fibrosis and shrinkage

Advantages

  • Simple

  • Day-care procedure

B. TURBINOPLASTY (PREFERRED MODERN METHOD)

  • Partial reduction of turbinate

  • Mucosa preserved

Advantages

  • Good airflow

  • Minimal complications

C. PARTIAL TURBINECTOMY

  • Removal of turbinate portion

  • Used in severe cases

Disadvantages

  • Risk of atrophic rhinitis

  • Excessive bleeding if careless

D. RADIOFREQUENCY ABLATION

  • Minimally invasive

  • Causes controlled tissue necrosis

  • Gradual volume reduction

E. LASER TURBINATE REDUCTION

  • COâ‚‚ / diode laser

  • Precise

  • Less bleeding

16.3 SURGERY WITH DNS

  • Septoplasty + turbinate reduction

  • Treats primary cause of compensatory hypertrophy

17. POSTOPERATIVE CARE

  • Nasal saline irrigation

  • Analgesics

  • Avoid nose blowing

  • Regular follow-up endoscopy

18. COMPLICATIONS OF SURGERY

  • Bleeding

  • Crusting

  • Synechiae

  • Over-resection → atrophic rhinitis

21. SPECIAL CLINICAL SCENARIOS (EXAM-FOCUSED)

21.1 HYPERTROPHIC RHINITIS IN CHILDREN

  • Less common than in adults

  • Usually secondary to:

    • Adenoid hypertrophy

    • Chronic infection

    • Allergic rhinitis

  • Inferior turbinate enlargement often reversible

Management Principle

  • Septoplasty must be combined with turbinate reduction

  • Treating turbinate alone → high recurrence

21.3 DRUG-INDUCED HYPERTROPHIC RHINITIS

  • Seen with prolonged topical decongestant use

  • Overlaps with rhinitis medicamentosa

Clinical Clue

  • History of long-term nasal spray use

  • Poor response to steroids

Management

  • Gradual withdrawal

  • Intranasal steroids

  • Saline irrigation

  • Surgery if irreversible hypertrophy develops
