Understanding Acute Sinusitis: Symptoms, Causes, and Treatments

What is acute sinusitis?

Acute sinusitis is a temporary condition characterised by the swelling and inflammation of the sinus linings. It typically lasts for less than four weeks and often results from a viral or bacterial infection. Let us first start with understanding the sinuses. They are small, air-filled cavities located behind the cheekbones, forehead, and nasal area. When these spaces become inflamed, they can cause discomfort, pressure, and other unpleasant symptoms.

Understanding the Symptoms of Acute Sinusitis

Individuals with acute sinusitis may experience a range of symptoms, including:

• Facial Pain or Pressure: Depending on the affected sinus, individuals can feel pressure or discomfort around the eyes, cheeks, or forehead.
• Nasal congestion or stuffiness: The inflammation can obstruct the nasal passages, making breathing difficult.
• Thick, Discoloured Nasal Discharge: The mucus produced during acute sinusitis is often thick and may appear yellow or green.
• Postnasal Drip: Sometimes, nasal discharge may drip down the throat, causing throat irritation.
• Headache or Sinus Pain: The pressure buildup within the sinuses can lead to throbbing headaches or pain in the sinus areas.
• Fever: In some cases, acute sinusitis may accompany a low-grade fever.
• Fatigue or General Malaise: The body’s immune response against the infection can cause feelings of tiredness or weakness.
• Cough or Sore Throat: Sinus drainage may cause throat irritation, leading to a persistent cough or sore throat.
• Other Accompanying Symptoms: Acute sinusitis may cause ear pressure or pain, a changed sense of smell, bad breath (halitosis), and a toothache.

Common Causes of Acute Sinusitis

Several factors can contribute to the development of acute sinusitis, including:

• Viral Infections: Acute sinusitis often starts with a viral infection, such as the common cold or flu, which can lead to sinus inflammation.
• Bacterial Infections: A bacterial infection can sometimes follow a viral infection, causing further inflammation and symptoms.
• Allergies: Allergic reactions to airborne substances like pollen, dust, or pet dander can trigger sinus inflammation and congestion.
• Structural Abnormalities: Individuals with structural issues in their nasal passages (deviated septum or nasal polyps) may be more prone to developing acute sinusitis.
• Environmental Factors: Exposure to pollutants, smoke, or dry air can irritate the sinus linings and increase the risk of acute sinusitis.
• Diving or Swimming: Waters entering the sinuses through swimming or diving can lead to inflammation or infection of the sinuses.
• Weakened Immune System: People with conditions like HIV/AIDS or cystic fibrosis that weaken the immune system have increased the risk of infections.
• Dental Infections: Sometimes, maxillary teeth infections can spread to the sinuses.

Diagnosing Acute Sinusitis

To diagnose acute sinusitis, doctors may perform:

• Physical Examination: The ENT specialist will examine the patient’s nose, face, and throat for signs of inflammation, tenderness, and structural abnormalities.
• Imaging Tests: In some cases, doctors may conduct imaging techniques like CT scans or X-rays to visualise the sinus cavities and identify blockages or abnormalities.
• Nasal Endoscopy: The ENT specialist inserts a thin, flexible tube with a camera into the nasal passages to inspect the sinus openings and detect any obstructions or inflammation.

Treatment Options for Acute Sinusitis

The acute sinusitis treatment varies with the nature of the symptoms and the underlying cause. The following are some common treatment options:

A. Medications for Relieving Acute Sinusitis

• Decongestants: These sinusitis medications can reduce nasal congestion and relieve sinus pressure by constricting blood vessels in the nasal passages.
• Antihistamines: Antihistamines can help alleviate symptoms in individuals with allergic sinusitis by antagonising the action of histamine (a chemical secreted during an allergic reaction).
• Pain Relievers: Over-the-counter (OTC) pain medications, such as acetaminophen or ibuprofen, can provide relief from headaches and facial pain associated with acute sinusitis.
• Nasal Corticosteroid Sprays: These sprays decrease inflammation and swelling in the nasal passages and sinuses, improving drainage and reducing congestion.
• Antibiotics: Doctors may prescribe antibiotics to treat the underlying infection and alleviate symptoms if a bacterial infection is suspected.

B. Invasive Intervention:

• Balloon Sinuplasty: Doctors may perform this minimally invasive procedure to open blocked sinus passages.
• Endoscopic Surgery: In chronic or recurrent cases, the doctor may prescribe surgical management to remove blockages and polyps or to correct structural issues.

Home Remedies for Managing Acute Sinusitis

In addition to medications, several home remedies can help alleviate the symptoms of acute sinusitis:

• Nasal Irrigation: Saline rinsing of the nasal passages can help flush out mucus and irritants, promote drainage, and reduce inflammation.
• Steam Inhalation: Breathing in warm, moist air from a humidifier or steam bath can help thin out mucus and provide temporary relief from congestion.
• Warm Compresses: Warm, moist compresses to the face relieve sinus pressure and pain, says “Dr. Prashanth R Reddy.”
• Hydration: Drinking an optimal amount of fluids, such as water or warm beverages, can help thin out mucus and promote drainage.
• Rest: Getting adequate rest can support the body’s immune system and aid in the recovery process.

Prevention

While acute sinusitis can be challenging to prevent completely, there are steps individuals can take to reduce their risk:

• Practice Good Hygiene: Wash your hands thoroughly & regularly and avoid touching your face. Always cover your mouth with a handkerchief or napkin when coughing or sneezing to prevent spreading infections.
• Manage Allergies: If you have allergies, take appropriate measures to control them, such as using antihistamines or avoiding known triggers.
• Quit Smoking: Smoking irritates the nasal passages and increases the risk of sinus infections.
• Use a Humidifier: Keeping indoor air moist prevents dryness and irritation in the nasal passages.
• Stay Hydrated: Drinking optimal fluids helps to thin out mucus and promote proper drainage.

When to See a Doctor for Acute Sinusitis

While acute sinusitis often resolves on its own or with home remedies, it’s essential to seek medical attention in certain situations:

• Severe or Persistent Symptoms: If your symptoms are severe or do not improve within a week, consult a doctor.
• High Fever: A fever higher than 101°F (38.3°C) indicates a more serious infection and requires medical evaluation.
• Visual Disturbances: If you experience vision problems, such as double vision or swelling around the eyes, seek immediate medical attention.
• Neurological Symptoms: Seek medical care if you experience symptoms like severe headaches, confusion, or altered mental status.
• Recurrent Episodes: If you experience frequent or recurring sinus infections, it’s advisable to consult a doctor to identify and address any underlying causes.

Difference between Acute Sinusitis and Chronic Sinusitis

While acute sinusitis is a temporary condition, chronic sinusitis is a long-lasting inflammation of the sinus cavities. The main differences include:

• Duration: Acute sinusitis lasts less than four weeks, while chronic sinusitis lasts more than twelve weeks.
• Causes: Acute sinusitis is often triggered by viral or bacterial infections, while chronic sinusitis can result from various factors, including structural abnormalities, allergies, or immune system disorders.
• Symptoms: The symptoms of acute sinusitis are typically more severe and may include fever, while chronic sinusitis can cause more persistent symptoms like nasal congestion and facial pain.
• Treatment: Acute sinusitis is usually treated with medications and home remedies, while chronic sinusitis may require more planned treatment approaches, such as surgery or long-term medication.

Conclusion

Acute sinusitis is a common condition that results in discomfort and disruption to daily life. By understanding the symptoms, causes, and available options for treating acute sinusitis, individuals can effectively manage and alleviate the effects of acute sinusitis. If symptoms of acute sinusitis persist or worsen, seeking medical attention promptly to prevent complications and receive appropriate treatment is crucial.
