Pristyn Care ZOI Hospital, Ameerpet, Hyderabad Pristyn Care La Midas, Main, Nathupur Rd, nr. 38, DLF Phase 3, Sector 24, Gurugram, Haryana 122002Subacute sinusitis is a type of sinus inflammation that lasts longer than acute sinusitis but does not persist long enough to be classified as chronic. It typically lasts between 4 to 12 weeks.
The condition occurs when the sinus cavities remain inflamed and blocked, leading to mucus buildup, pressure, and ongoing discomfort. It often develops after an untreated or partially treated acute sinus infection.
Although less severe than chronic sinusitis, subacute sinusitis can still significantly affect breathing, sleep, and daily functioning.
Subacute sinusitis is relatively common but often overlooked because symptoms overlap with other sinus conditions.
Some key facts include:
1. Bacterial Subacute Sinusitis
Caused by lingering bacterial infection after a cold or flu.
2. Viral Triggered Subacute Sinusitis
Starts as a viral infection that leads to prolonged inflammation.
3. Allergic Subacute Sinusitis
Triggered by allergies that prolong sinus swelling and mucus buildup.
4. Post Infectious Inflammatory Sinusitis
Inflammation continues even after infection is resolved.
Symptoms are milder than chronic sinusitis but last longer than acute infections.
Common Symptoms:
In Persistent Cases:
1. Untreated Acute Sinus Infection
Most common cause when infection does not fully resolve.
2. Bacterial Infection
Bacteria trapped in sinuses due to blockage.
3. Allergies
Allergic inflammation prolongs sinus swelling.
4. Upper Respiratory Infections
Common cold or flu triggering prolonged symptoms.
5. Nasal Blockage
Due to deviated septum or nasal polyps.
6. Environmental Irritants
Pollution, smoke, or chemical exposure.
7. Weak Immune System
Reduced ability to clear infections effectively.
If not treated properly, subacute sinusitis may lead to:
Doctors diagnose the condition using:
1. Clinical Evaluation
Review of symptoms and duration.
2. Nasal Examination
Inspection of nasal passages for swelling or discharge.
3. Nasal Endoscopy
A small camera is used to view sinus openings.
4. CT Scan of Sinuses
Helps detect inflammation, blockage, or fluid buildup.
5. Allergy Testing
Identifies allergic triggers contributing to symptoms.
Treatment focuses on reducing inflammation and clearing infection.
1. Medications
2. Home Care
3. Allergy Management
4. Surgical Treatment

Mostly unresolved infections or allergies.
The condition itself is not contagious, but underlying infections may be.
Through symptoms, nasal exam, and CT scan if needed.
Medications, nasal sprays, and steam inhalation.
Mild cases may improve, but treatment helps faster recovery.
If symptoms last more than 10 to 14 days or worsen
