Another Benefit to Quitting Smoking: Improved Sinus Function

Smoking is the leading cause of preventable death in the United States, contributing to hundreds of thousands of deaths each year. Beyond lung disease and cancer, smoking also has significant effects on the sinuses.

Research now shows that quitting smoking can improve chronic sinusitis symptoms over time, offering yet another compelling reason to stop smoking.

What is sinusitis?

Chronic sinusitis is defined as ongoing sinus inflammation lasting longer than three months despite treatment. Swelling blocks normal sinus drainage, leading to symptoms such as:

• Nasal congestion
• Discolored postnasal drainage
• Decreased sense of smell
• Facial pressure or headaches
• Fatigue

Diagnosis is typically made using nasal endoscopy or CT imaging. Some patients require surgery or balloon sinuplasty if medication alone does not help.

How are smoking and sinus infections connected?

Smoking damages the sinuses in several ways:

• Impairs mucus clearance
• Increases swelling and inflammation
• Worsens nasal obstruction
• Intensifies sinusitis symptoms

Smokers commonly report more severe and persistent sinus infections compared to non‑smokers, along with decreased quality of life due to poor sleep and breathing difficulties.

Can quitting smoking improve sinusitis?

Yes. A long‑term study found that chronic sinusitis patients who quit smoking experienced steady improvement in symptoms over a 10‑year period. Importantly, patients did not need to wait a decade to feel better—each year without smoking led to measurable improvement and reduced reliance on medication.

“This is another study showing the significant health impacts that smoking has,” CEENTA Otolaryngologist Jonathan Moss, MD, said. “Our specialty treats many patients who suffer from chronic sinusitis, and it’s just one of many health issues that smokers have to deal with. We can improve sinus function with medications and surgery, but smoking cessation not only improves quality of life but will save your life.”

When should you see an ENT specialist?

If you experience:

• Frequent sinus infections
• Symptoms lasting longer than three months
• Poor response to antibiotics
• Ongoing facial pressure or congestion

An ENT evaluation can determine whether medical therapy, balloon sinuplasty, or surgical treatment is appropriate. Schedule your same-day appointment with Dr. Jonathan Moss at CEENTA Matthews online or through myCEENTAchart.
