What is Chronic Sinusitis ?


Chronic sinusitis, also known as chronic rhinosinusitis, is a long-term inflammation of the sinuses that lasts for 12 weeks or longer, despite medical treatment. This condition causes persistent nasal blockage, facial pressure, headaches, and breathing difficulties, often disrupting sleep and daily life.

Chronic sinusitis matters because it is one of the most common ENT conditions in India, affecting millions of people and significantly reducing quality of life. If left untreated, it may lead to complications such as repeated infections, vision problems, or even reduced sense of smell. 

At THANC Hospital, Chennai, our ENT specialists provide advanced diagnosis and personalized treatments, ensuring patients find long-term relief and improved well-being.

Understanding Chronic Sinusitis

Chronic sinusitis occurs when the sinuses (air-filled cavities around the nose) remain inflamed and swollen for an extended period, interfering with normal mucus drainage.

Causes of Chronic Sinusitis

  • Persistent respiratory infections
  • Nasal polyps (growths in the nasal passages)
  • Deviated nasal septum
  • Allergies (dust, pollen, pollution)
  • Fungal or bacterial infections
  • Weakened immune system

Risk Factors & Who is Affected

  • People with asthma or allergies
  • Individuals living in polluted environments
  • Patients with frequent colds or infections
  • Those with structural nasal issues
  • Adults more than children, though both can be affected

Common Symptoms of Chronic Sinusitis

Key Symptoms

  • Persistent nasal congestion or blockage
  • Thick nasal discharge (yellow or green)
  • Facial pain, pressure, or fullness
  • Headaches
  • Postnasal drip (mucus at the back of the throat)
  • Reduced or lost sense of smell and taste
  • Chronic cough, worse at night

When to Seek Medical Help

Seek immediate consultation if you experience:

  • Severe headaches not relieved by medication
  • Swelling around the eyes or forehead
  • Blurred or double vision
  • Persistent fever with sinus symptoms
  • Difficulty breathing

Diagnosis of Chronic Sinusitis

At THANC Hospital, Chennai, we use state-of-the-art diagnostic methods to accurately identify chronic sinusitis and its underlying causes:

  • Nasal endoscopy for direct sinus evaluation
  • CT scan of the sinuses for detailed imaging
  • Allergy testing to identify triggers
  • Nasal and sinus cultures for infections

Our advanced ENT diagnostic facilities ensure precise assessment and effective treatment planning.

Treatment Options for Chronic Sinusitis

Non-Surgical / Medical Treatments

  • Nasal corticosteroid sprays to reduce inflammation
  • Saline nasal irrigation to clear mucus
  • Antibiotics (if bacterial infection is confirmed)
  • Antihistamines and decongestants for allergy-related sinusitis
  • Immunotherapy for chronic allergy management
  • Lifestyle advice such as avoiding pollution and staying hydrated

Surgical / Advanced Treatments

For patients who do not respond to medications, surgical options may be recommended:

  • Functional Endoscopic Sinus Surgery (FESS): Minimally invasive procedure to open blocked sinuses
  • Balloon Sinuplasty: Gentle expansion of sinus passages for improved drainage
  • Correction of deviated nasal septum (Septoplasty) if structural issues contribute

Our expert ENT surgeons at THANC Hospital are pioneers in advanced sinus surgery, ensuring high success rates and faster recovery.
