Rhinoscleroma is a rare, chronic bacterial infection that primarily affects the respiratory tract, especially the nose and nasal passages. It can also spread to the throat, voice box, windpipe and other parts of the upper airway.

The condition causes long-lasting inflammation that may gradually lead to tissue thickening, scarring and narrowing of the affected airways. Without treatment, these changes can cause nasal deformity and difficulty breathing.

Early diagnosis and appropriate antibiotic treatment are important for controlling the infection and reducing the risk of permanent tissue damage or airway complications.

What Are the Types of Rhinoscleroma?

Rhinoscleroma usually progresses through different pathological stages rather than distinct disease types. These stages may overlap and can affect the appearance and severity of symptoms.

Catarrhal Stage: The early stage causes inflammation, persistent nasal discharge, crusting and nasal congestion.
Granulomatous Stage: Granulomatous tissue develops in the affected areas and may cause swelling, nasal obstruction or visible masses.
Sclerotic Stage: Fibrosis and scarring develop, which can narrow the nasal passages or other parts of the respiratory tract.

What Are the Symptoms of Rhinoscleroma?

Symptoms of rhinoscleroma usually develop gradually and depend on the stage of the infection and the part of the respiratory tract affected.

Nasal Congestion: Swelling and tissue growth can block the nasal passages and make breathing through the nose difficult.
Nasal Discharge: Persistent nasal discharge may occur, particularly during the early stage of the infection.
Difficulty Breathing: Progressive narrowing of the nasal passages or other airways can interfere with normal breathing.
Nosebleeds: Inflamed or damaged nasal tissues may bleed easily.
Nasal Crusting: Dry crusts may develop inside the nose and cause irritation or discomfort.
Reduced Sense of Smell: Nasal blockage and inflammation may interfere with the ability to smell.
Nasal Deformity: Long-term inflammation and scarring can alter the shape of the nose.
Voice Changes: Involvement of the throat or voice box may cause hoarseness or other changes in the voice.

What Causes Rhinoscleroma?

Rhinoscleroma is caused by chronic infection with the bacterium Klebsiella rhinoscleromatis. The infection usually begins in the nasal passages and can gradually spread to nearby parts of the respiratory tract.

Klebsiella Rhinoscleromatis Infection

The bacterium Klebsiella rhinoscleromatis is the primary cause of rhinoscleroma. Long-term infection triggers chronic inflammation and the formation of granulomatous tissue.

Prolonged Close Contact

Repeated or prolonged close contact with an infected person may increase the likelihood of exposure, although the exact mode of transmission is not completely understood.

Poor Sanitation and Hygiene

Limited access to clean water, poor hygiene practices and inadequate sanitation may contribute to the spread of the infection.

Crowded Living Conditions

Living in crowded environments may increase opportunities for prolonged exposure to the bacteria.

When Should You See a Doctor for Rhinoscleroma?

Medical evaluation by an ENT Specialist or Infectious Disease Specialist is recommended when persistent nasal symptoms do not improve, gradually worsen, or cause breathing difficulties. Early diagnosis is important because untreated rhinoscleroma can lead to progressive scarring, airway narrowing, and permanent tissue damage.

You should see a doctor if you have:

Persistent nasal congestion or discharge that does not improve
Recurring nosebleeds, nasal crusting or reduced sense of smell
Gradual changes in the shape of the nose or persistent nasal swelling

Get medical help immediately if:

Severe difficulty breathing or rapidly worsening airway obstruction occurs
Swelling in the throat causes difficulty swallowing or breathing
Severe respiratory distress or bluish discoloration develops

These could be signs of a serious complication like airway obstruction, which needs urgent care.

How Is Rhinoscleroma Diagnosed?

Diagnosing rhinoscleroma usually involves a physical examination, evaluation of the nasal passages and laboratory examination of affected tissue. Several tests may be needed because the condition can resemble other chronic infections or nasal disorders.

Medical History and Physical Examination

The doctor may ask about the duration of symptoms, living conditions, previous infections and any progressive changes in breathing or the appearance of the nose.

Nasal Endoscopy

Nasal endoscopy allows the doctor to examine the nasal passages for inflammation, masses, crusting, scarring and airway narrowing.

Biopsy

A biopsy of the affected tissue is often important for confirming the diagnosis. The sample is examined for characteristic inflammatory cells and bacterial changes associated with rhinoscleroma.

Bacterial Culture

Samples from nasal tissue or discharge may be tested to identify Klebsiella rhinoscleromatis and help guide antibiotic treatment.

Imaging Tests

CT or MRI scans may be recommended when the infection is extensive or when the doctor needs to assess involvement of the sinuses, throat or other airway structures.

How Is Rhinoscleroma Treated?

Treatment for rhinoscleroma focuses on eliminating the bacterial infection, relieving airway obstruction and managing tissue damage. Long-term treatment and regular follow-up may be necessary because the condition can recur.

Antibiotic Therapy

Antibiotics are the main treatment for rhinoscleroma. The choice and duration of treatment depend on the severity of the infection, bacterial test results and response to therapy.

Surgical Treatment

Surgery may be required when thickened tissue or severe scarring causes significant nasal or airway obstruction. The procedure can remove obstructive tissue and improve breathing.

Laser Therapy

Laser treatment may be used in selected cases to remove or reduce obstructive tissue and improve airflow through the affected passages.

Airway Management

Severe narrowing of the respiratory tract may require procedures to restore or protect the airway.

Supportive Care

Saline nasal rinses, humidification and other supportive measures may help reduce nasal dryness, crusting and discomfort during recovery.

What Are the Risk Factors for Rhinoscleroma?

Certain environmental and health-related factors may increase the likelihood of developing rhinoscleroma.

Poor Sanitation: Limited access to clean water and adequate sanitation may increase exposure to infection.
Crowded Living Conditions: Prolonged close contact with others may increase the risk of bacterial transmission.
Poor Hygiene Practices: Inadequate hygiene may contribute to the spread of respiratory infections.
Living in Endemic Areas: The infection is more frequently reported in certain regions where environmental and socioeconomic conditions favour transmission.
Weakened Immune Function: Reduced immune defences may increase susceptibility to chronic infections.

What Are the Complications of Rhinoscleroma?

Untreated or advanced rhinoscleroma can cause progressive tissue damage and narrowing of the respiratory tract.

Airway Obstruction: Scar tissue and abnormal tissue growth can narrow the nose, throat or other airways.
Nasal Deformity: Chronic inflammation and fibrosis may permanently alter the structure of the nose.
Loss of Smell: Persistent nasal damage can reduce or impair the sense of smell.
Voice Changes: Spread of the infection to the voice box may cause persistent hoarseness.
Tissue Damage: Severe inflammation may contribute to ulceration or necrosis of affected tissues.
Recurrence: The condition may return after treatment, particularly if the infection is not completely eliminated.

How Can Rhinoscleroma Be Prevented?

There is no specific vaccine for rhinoscleroma, but measures that reduce exposure to infection may help lower the risk.

Maintain good personal and respiratory hygiene.
Wash hands regularly with soap and clean water.
Improve sanitation and access to clean living environments.
Avoid prolonged close contact with untreated infected individuals.
Seek medical care for persistent nasal symptoms or breathing problems.
Complete the full course of prescribed antibiotics.
Attend follow-up appointments to check for recurrence.

What Is the Outlook for Rhinoscleroma?

The outlook for rhinoscleroma is generally better when the condition is diagnosed early and treated with appropriate antibiotics. Early treatment can control the infection and reduce the risk of permanent scarring or airway obstruction.

Advanced disease may require surgery in addition to antibiotics, and recurrence can occur. Regular follow-up is important for monitoring recovery, identifying recurrent infection and managing long-term breathing or structural problems.

Frequently Asked Questions
