The following CBME core competencies are covered in this chapter. EN4.29: Elicit, document and present a correct history, demonstrate and describe the clinical features, choose the correct investigations and describe the principles of management of acute and chronic rhinitis.

Chronic Rhinitis: Types, Symptoms, Treatment, Notes & MCQs

Chronic rhinitis is persistent inflammation of the nasal mucosa lasting more than 12 weeks and commonly causing nasal obstruction, rhinorrhoea, sneezing, postnasal drip, or nasal irritation. The condition has several causes and clinical patterns, ranging from reversible mucosal congestion to turbinate hypertrophy and atrophic changes. Unlike acute rhinitis, which usually resolves spontaneously, chronic rhinitis progresses slowly and often results from repeated infections, environmental irritation, or structural abnormalities of the nose.

For ENT examinations, chronic rhinitis is commonly discussed under chronic simple rhinitis, chronic hypertrophic rhinitis, atrophic rhinitis (ozaena), rhinitis sicca, and rhinitis caseosa. The most important clinical distinction is between the relatively reversible mucosal changes of simple rhinitis and the more persistent structural changes seen in hypertrophic rhinitis.

Atrophic rhinitis has a characteristic combination of foul-smelling crusts, a roomy nasal cavity, and merciful anosmia, whereas rhinitis sicca mainly affects the anterior nasal cavity and presents with dryness, crusting, and epistaxis.

This chapter provides MBBS and ENT PG notes on chronic rhinitis, including classification, causes, pathology, clinical features, diagnosis, treatment, turbinate surgery, atrophic rhinitis, CBME competency EN4.29, viva questions, clinical cases, and NEET PG-style MCQs.

Classification of Chronic Rhinitis

For a conceptual understanding, chronic rhinitis can be broadly classified into specific and non-specific inflammations. This chapter focuses on the latter.

Chronic Non-Specific Rhinitis

1. Chronic Simple Rhinitis
2. Chronic Hypertrophic Rhinitis
3. Chronic Atrophic Rhinitis (Primary & Secondary)
4. Rhinitis Sicca
5. Rhinitis Caseosa

It is important to remember that these are not always distinct entities but rather represent a spectrum of chronic inflammatory change. However, atrophic rhinitis is a distinct disorder and should not be presented as the inevitable end stage of chronic hypertrophic rhinitis.

1. Chronic Simple Rhinitis

Chronic simple rhinitis represents persistent low-grade inflammation of the nasal mucosa, usually resulting from repeated episodes of acute rhinitis. It is considered an early stage in the progression toward chronic hypertrophic rhinitis. It is characterised by vascular engorgement and glandular hyperactivity without permanent tissue thickening.

Aetiology

The condition typically arises from recurrent acute attacks of rhinitis, which fail to resolve completely due to various predisposing factors. These factors can be remembered using the mnemonic NOSE:

• Nasal and Paranasal Factors: Persistent infection due to chronic sinusitis, adenoiditis, or tonsillitis.
• Obstructive Factors: Mechanical obstruction, such as a deviated nasal septum (DNS), synechiae (adhesions), or foreign bodies, which lead to stasis of secretions.
• Systemic and Environmental Factors: Endocrine or metabolic disorders (e.g., hypothyroidism, , excessive intake of carbohydrates and lack of exercise), and chronic irritation from dust, smoke, or cigarette smoking.
• External Irritants: Occupational hazards, snuff, and sudden changes in temperature and humidity.

Pathology

In chronic simple rhinitis, the nasal mucosa shows persistent vascular congestion and mild hypertrophic changes. The pathology reveals:

• Vasodilatation: The blood sinusoids, particularly over the turbinates, are distended.
• Glandular Hyperplasia: There is an increase in the number and activity of seromucinous glands and goblet cells, leading to hypersecretion.
• Oedema: The submucosa shows inflammatory oedema.

Crucially, all these changes are reversible if the causative factors are identified and treated early. The mucosa pits on pressure because the underlying stroma is oedematous and not fibrosed.

Clinical Features

• Nasal Obstruction: This is the hallmark symptom. Obstruction often worsens during sleep because venous congestion increases in the dependent nasal cavity. As a result, patients frequently report alternating nasal blockage.
• Nasal Discharge: The discharge is mucoid or mucopurulent, thick, and viscid. It often trickles down the throat as a postnasal drip, leading to a constant desire to clear the throat.
• Headache: A dull, non-localised headache can occur due to swollen turbinates impinging on the nasal septum.
• Examination Findings (Anterior Rhinoscopy) :
  • Nasal Mucosa: Dull red or pink in colour, not pale as in allergy.
  • Inferior Turbinate: Swollen, but soft and boggy. It pits on pressure with a probe and shrinks dramatically after application of a vasoconstrictor (e.g., 0.1% xylometazoline). This diagnostic feature differentiates it from hypertrophic rhinitis. The middle turbinate may also be swollen and impinge on the septum.

Management

The cornerstone of treatment is reversing the pathology and eliminating causative factors.

1. Treat the Cause: Address underlying factors like sinusitis (with antibiotics), adenoids (surgery), DNS (septoplasty), and allergy. Advise the patient to stop smoking and avoid dusty environments.

2. Medical Therapy:

• Nasal Decongestants: Topical decongestants (e.g., xylometazoline) can provide short-term relief for severe blockage. However, they should be used only for short-term relief, generally no longer than 3–5 days, because prolonged use can cause rebound congestion (rhinitis medicamentosa).
• Nasal Steroids: Intranasal corticosteroid sprays (e.g., fluticasone, mometasone) are the mainstay of treatment. They reduce inflammation and oedema without the risk of rebound congestion.
• Nasal Saline Irrigations: Alkaline nasal douching helps clear thick, viscid secretions and improves mucociliary clearance.
• Systemic Antibiotics: Antibiotics are not routinely indicated for uncomplicated chronic rhinitis. They should be used only when there is a documented or strongly suspected bacterial infection for which antimicrobial treatment is appropriate.

2. Chronic Hypertrophic Rhinitis

This represents persistent mucosal and, in some patients, bony hypertrophic changes that may respond incompletely to medical treatment. The changes are more marked on the turbinates. The changes are more marked on the turbinates.

Aetiology

The causes are largely the same as those of chronic simple rhinitis, but the inflammation is more severe and prolonged. Common causes include recurrent nasal infections, chronic sinusitis, and persistent irritation from smoking or industrial dust. It can also result from long-standing allergic or vasomotor rhinitis.

Pathology

The key pathological shift is from reversible oedema to irreversible fibrosis.

• Mucosa and Submucosa: There is thickening due to fibrosis, cellular infiltration, and hyperplasia of glands.
• Periosteum and Bone: The turbinate bones undergo true hypertrophy.
• Turbinate Changes: The inferior turbinate is most commonly affected. It can be hypertrophied in its entirety or only at specific points: the anterior tip, posterior end (which can block the Eustachian tube), or the inferior border (giving it a mulberry appearance).

Clinical Features

Symptoms:

• Nasal Obstruction: This is the predominant symptom and is typically persistent and bilateral, without the marked alternation seen in simple rhinitis.
• Discharge: The discharge is thick, mucopurulent, and sticky, making it difficult to blow out.
• Other Symptoms: Patients may complain of a sensation of heaviness in the head, dull headache, and transient or persistent hyposmia (reduced smell).

Examination Findings:

• Turbinate Appearance: The turbinates are enlarged and have a firm, nodular feel.
• Probe Test: The mucosa is firm and does not pit on pressure due to underlying fibrosis.
• Response to Vasoconstrictor: There is minimal to no shrinkage after applying a decongestant. This is the single most important clinical sign differentiating it from chronic simple rhinitis.

Treatment

Management aims to relieve nasal obstruction by reducing the size of the turbinates while preserving as much normal mucosa as possible.

1. Conservative Medical Management: A trial of intranasal steroids may be given for early hypertrophic changes, but the response is often poor.

2. Surgical Reduction of Turbinates: Various surgical options exist, and the choice depends on the type and site of hypertrophy.

• For Soft Tissue Hypertrophy:
  • Submucosal Diathermy (SMD): A needle electrode is inserted into the submucosa of the turbinate, delivering heat to cause coagulation and scarring, thereby reducing the soft tissue bulk.
  • Cryosurgery: Freezing the turbinate tip to cause necrosis and shrinkage.
  • Radiofrequency Ablation (RFA) / Coblation: A modern, minimally invasive technique that uses radiofrequency energy to create controlled submucosal tissue destruction, preserving the mucosal surface.
  • Laser-Assisted Turbinoplasty: Using a laser (e.g., diode or CO2) to vaporise a strip of the turbinate.
• For Bony Hypertrophy:
  • Partial Turbinectomy: Surgical excision of the hypertrophied part (anterior end, inferior border, or posterior end).
  • Submucous Resection of Turbinate Bone: This is an excellent procedure that removes the hypertrophied bone but preserves the overlying mucosa, thus maintaining its physiological function. It is the preferred method for bony hypertrophy.
• Surgical Tip: Excessive turbinate tissue removal can disrupt nasal airflow and mucosal function and has been associated with empty nose syndrome. Modern turbinate surgery therefore emphasises mucosal preservation and conservative tissue reduction.

Compensatory Hypertrophic Rhinitis

This is a unique phenomenon seen in cases of marked deviated nasal septum (DNS) . When the septum deviates significantly to one side, the nasal cavity on the other (wider) side becomes roomy. To protect this wider cavity from the ill effects of excessive airflow, drying, and crusting, the inferior and middle turbinates on that side undergo hypertrophy. This is a compensatory response to protect the wider nasal cavity from excessive airflow. Persistent turbinate enlargement may not completely regress after septal correction, and turbinate reduction may be considered when clinically significant obstruction persists.

3. Atrophic Rhinitis (Ozaena)

Atrophic rhinitis is a distinct and chronic condition characterised by progressive atrophy of the nasal mucosa, submucosa, and turbinate bones. This results in a roomy nasal cavity that is paradoxically full of foul-smelling crusts. The term Ozaena is used for the classic, fetid form of primary atrophic rhinitis.

Aetiology

Atrophic rhinitis is broadly divided into primary and secondary types.

Primary Atrophic Rhinitis (Unknown aetiology)

The exact cause remains unknown, but several theories exist, remembered by the mnemonic HERNIA:

• Hereditary: Familial tendency has been observed.
• Endocrine: Onset at puberty, female preponderance, and spontaneous remission after menopause suggest a hormonal link.
• Nutritional: Deficiency of iron, vitamins A, D, or E, often associated with low socioeconomic status, may play a role.
• Infective: Various organisms like Klebsiella ozaenae (Perez bacillus), Coccobacillus foetidus ozaena, Proteus, and Diphtheroids are found. However, their role as primary causative organisms remains uncertain, and they may be secondary invaders responsible for the foul smell.
• Autoimmune: An autoimmune process causing chronic vasculitis and tissue destruction is a strong hypothesis. Evidence of endarteritis and periarteritis in mucosal vessels supports this.

Secondary Atrophic Rhinitis

This form has a clear, identifiable cause, such as:

• Iatrogenic: Excessive and radical surgery of the nose or sinuses (e.g., excessive turbinectomy).
• Granulomatous Diseases: Conditions like granulomatosis with polyangiitis (GPA; formerly Wegener’s granulomatosis), tuberculosis, syphilis, leprosy, and scleroma.
• Radiation: Post-radiotherapy for sinonasal malignancies.
• Trauma: Severe facial trauma damaging the nasal mucosa.

Pathology

The histopathological hallmarks include:

• Epithelial Metaplasia: The normal ciliated columnar respiratory epithelium transforms into non-keratinised squamous epithelium.
• Vascular Changes: Obliterative endarteritis and periarteritis of terminal arterioles lead to decreased vascularity and ischaemic atrophy of the mucosa and glands.
• Glandular Atrophy: There is a marked decrease in the number and size of mucus glands.
• Bony Resorption: The turbinate bones undergo progressive resorption, leading to grossly patent nasal cavities.
• Sinus Development: Paranasal sinuses are often small and underdeveloped (micro-sinuses) with thick bony walls.

Clinical Features

• Demographics: Classically affects females, starting around puberty.
• Symptoms:
  • Foul Smell (Foetor): The patient emits a characteristic, offensive smell from the nose and mouth. Paradoxically, the patient is unaware of this smell due to severe anosmia caused by atrophy of the olfactory mucosa. This is known as “Merciful Anosmia”. The foul smell makes the patient a social outcast.
  • Nasal Obstruction: Despite having wide nasal cavities, the patient complains of obstruction. This is due to the large crusts blocking the airway and the loss of sensory nerve endings, which normally sense the airflow.
  • Epistaxis: Minor bleeding occurs when crusts are dislodged.
  • Other Symptoms: Atrophic changes can extend to the pharynx (atrophic pharyngitis) and larynx (atrophic laryngitis), causing dryness of the throat and hoarseness of the voice. Conductive deafness can occur due to Eustachian tube blockage by crusts or by extension of the pathology.
• Signs (Anterior Rhinoscopy) :
  • Crusting: The nasal cavities are filled with thick, greenish or greyish-black dry crusts. Removing them may cause bleeding.
  • Roomy Nasal Cavities: After crust removal, the nasal cavities appear abnormally wide. The turbinates are atrophied to small ridges, allowing a direct view of the posterior wall of the nasopharynx (“patulous nasal cavity”). Septal perforation and dermatitis of the nasal vestibule may be present.
  • Mucosa: The nasal mucosa is pale, thin, and glazed.
  • External Deformity: A saddle-nose deformity may be present in long-standing cases.

Prognosis

The disease is chronic and tends to persist for years. However, there is a natural tendency for it to burn out and recover spontaneously by middle age, often after menopause.

Treatment

A complete cure is often difficult to achieve, especially in primary cases. Therefore, treatment is primarily palliative and aims to:

1. Remove crusts and foul smell.
2. Reduce crust formation.
3. Atrophy of the mucosa.

The management can be divided into medical and surgical approaches.

Medical Treatment (Palliative)

1. Nasal Irrigation (Douching): The first and most important step. The nose is irrigated with a warm alkaline solution, made by dissolving a teaspoonful of powder containing soda bicarbonate 1 part (28.4 g), sodium borate 1 part (28.4 g), sodium chloride 2 parts (56.7 g) in 280 mL of clean water. The solution is run through one nostril and comes out from the other. It loosens the crusts and removes thick, tenacious discharge. Care should be taken to avoid pushing the fluid into the sinuses and Eustachian tube. Initially, irrigations are done two or three times a day, but later, once every 2 or 3 days is sufficient. Hard crusts may be difficult to remove by irrigation. They are first loosened and then mechanically removed with forceps or suction.

2. Nasal Drops to Retain Moisture: Saline nasal sprays and lubricating ointments help keep the mucosa moist.

3. Systemic Therapy: Antibiotics such as ciprofloxacin or mupirocin ointment may reduce bacterial load and foul smell. Other systemic treatments have limited evidence.

Historical treatment note: Several older ENT textbooks describe glucose-glycerine preparations, oestrogen-containing drops, systemic vasodilators, potassium iodide, and antibiotics such as streptomycin. These treatments are largely historical and should not be presented as routine contemporary management.

Surgical Treatment

Surgical options are considered when medical management fails. The principle behind most surgeries is to narrow the excessively patent nasal cavity, thereby reducing crusting caused by the drying effect of rapid airflow.

1. Young’s Operation (Nostril Closure): This involves raising vestibular skin flaps and suturing them together to completely close one or both nostrils. The nasal cavity is closed for 6 months to a year, allowing the mucosa to rest, regenerate, and become healthy. In a Modified Young’s operation, a small 3mm hole is left for breathing and endoscopic examination.

2. Procedures to Narrow the Nasal Cavity:

• Wilson’s Operation: Submucosal injection of Teflon paste into the inferior turbinate and lateral wall to narrow the cavity.
• Lautenslauger’s Operation: This is a major procedure involving osteotomy and medial displacement of the lateral nasal wall.
• Implants: Insertion of cartilage, bone, or synthetic materials (Plastipore) under the mucoperiosteum of the floor and lateral wall.

Unilateral Atrophic Rhinitis

This condition can occur on the wider side of a nose with an extreme deviation of the nasal septum. The excessive unidirectional airflow leads to drying and secondary atrophic changes on that side.

4. Rhinitis Sicca

Rhinitis sicca is considered a milder, localised form of atrophic rhinitis. The atrophic changes are not diffuse but confined to the anterior part of the nasal cavity, particularly the anterior nasal septum.

Aetiology. It is commonly associated with:

• Environmental Factors: Working in hot, dry, and dusty environments (e.g., bakers, mill workers).
• Nutritional Factors: Anaemia and nutritional deficiencies.

Pathology. There is localised metaplasia of the normal ciliated epithelium to stratified squamous epithelium, along with decreased activity of the seromucinous glands in the anterior nasal cavity. The posterior part of the nasal cavity remains normal.

Clinical Features

• Symptoms: The primary symptoms are excessive crusting and epistaxis (nosebleeds) when the crusts are dislodged.
• Signs: Examination reveals dry crusts on the anterior part of the nasal septum. When these crusts fall off, they may expose an underlying ulcer on the septal mucosa. In advanced and neglected cases, this can deepen to form a septal perforation.

Treatment

• Medical: Iron and multivitamin supplements are given to correct any underlying deficiency.
• Local: Nasal douching with saline is highly effective in softening and removing crusts. Lubricating ointments can be applied to the nasal vestibule.

5. Rhinitis Caseosa

Rhinitis caseosa, also known as nasal cholesteatoma (a misnomer), is an uncommon sinonasal disorder characterised by accumulation of foul-smelling, cheesy, yellowish-white material in the nasal cavity and sinuses. Because unilateral caseous debris may mimic fungal disease or sinonasal neoplasia, endoscopic assessment and imaging are important in selected cases.

Aetiology and Pathology

The exact cause is unclear, but it is believed to result from suppurative inflammation with obstruction to the outflow of discharge. The obstruction can be due to a foreign body (e.g., rhinolith), a deviated nasal septum, or hypertrophied turbinates. The stagnant discharge becomes infected, leading to granulation tissue formation and accumulation of keratinous debris, cholesterol crystals, and fat. This mass gradually expands, causing pressure erosion of the nasal walls and even bone invasion.

Clinical Features

• Presentation: It is usually unilateral and more common in young adults.
• Symptoms: Patients present with unilateral nasal obstruction, foul-smelling purulent discharge, headache, and sometimes facial swelling.
• Signs: Anterior rhinoscopy reveals the nasal cavity filled with a whitish, cheesy, offensive-smelling debris. The underlying mucosa may show areas of granulation.

Diagnosis and Management

• Diagnosis: It is primarily clinical. A CT scan is essential to rule out sinus involvement, bone erosion, and to differentiate it from malignancy or fungal sinusitis.
• Treatment: The cornerstone of management is complete removal of all caseous material under endoscopic guidance. Once the debris is evacuated, a patent sinus ostium is established for drainage. Underlying causes, like a rhinolith or DNS, should be addressed. The prognosis is excellent with complete clearance.

Diagnosis of Chronic Rhinitis

Diagnosis is primarily clinical and based on a detailed history and nasal examination.

History: Ask about duration of symptoms (>12 weeks), nature of discharge, obstruction pattern, triggers, medication use (especially topical decongestants), history of allergy, and occupational exposure.

Examination: Anterior rhinoscopy assesses mucosal colour, turbinate size, and response to decongestants. Nasal endoscopy is indicated when posterior disease, polyps, or structural abnormalities are suspected.

Investigations:

• Allergy testing (skin-prick test or serum-specific IgE) is indicated when allergic rhinitis is suspected.
• CT of the paranasal sinuses is reserved for suspected sinusitis or pre-surgical planning.
• Biopsy is indicated if granulomatous disease or malignancy is suspected.

Differential Diagnosis of Chronic Nasal Obstruction

• Allergic rhinitis: itching, sneezing, clear discharge, positive allergy testing.
• Non-allergic rhinitis: non-specific triggers, negative allergy testing.
• Chronic rhinosinusitis: facial pain, purulent discharge, endoscopic or CT findings.
• Deviated nasal septum: structural deviation, often unilateral obstruction.
• Turbinate hypertrophy: enlarged turbinates, may be compensatory or inflammatory.
• Rhinitis medicamentosa: history of topical decongestant overuse, rebound congestion.
• Nasal polyps: polypoid mucosa on endoscopy, often bilateral.
• Foreign body: unilateral symptoms, purulent discharge, usually in children.
• Granulomatous disease: systemic symptoms, crusting, epistaxis, positive ANCA.
• Sinonasal tumour: unilateral obstruction, epistaxis, mass on endoscopy.
