Postnasal Drip

Postnasal drip can be uncomfortable and frustrating, and it’s a common cause of symptoms such as cough, sore throat, and hoarseness. While many may find relief from postnasal drip symptoms with over-the-counter remedies, postnasal drip that is chronic or long-lasting could be caused by a nasal condition that requires attention from a fellowship-trained sinus specialist.

Serving patients across Houston, The Woodlands, and surrounding areas, Dr. Shawn Allen provides advanced diagnostics and treatment options tailored to the root cause of your postnasal drip symptoms.

What is Postnasal Drip?

Postnasal drip occurs when excess mucus accumulates in the nasal passages and drains into the throat, leading to irritation. Mucus plays a protective role—moisturizing nasal tissues, filtering airborne particles, and fighting infection. Normally, you swallow this mucus unconsciously throughout the day.

However, when mucus becomes thick, excessive, or persistent, it becomes noticeable—causing throat clearing, coughing, or the sensation of mucus “sticking” in your throat. This is commonly referred to as postnasal drip.

How a Sinus Specialist Diagnoses Post-Nasal Drip

Diagnosing postnasal drip requires more than a basic physical exam. Dr. Allen uses advanced tools to identify the root cause:

  • Nasal Endoscopy: A small camera is used to examine the nasal passages and throat for structural issues, infection, or polyps.
  • CT Imaging: Helps evaluate chronic sinus disease, inflammation, or anatomical obstruction.
  • Allergy Testing: Identifies allergic triggers contributing to mucus production.
  • Reflux Evaluation: If GERD is suspected, your history and symptoms will be reviewed, and referrals may be made as needed.

Dr. Allen will create a personalized treatment plan based on the findings, helping you move from chronic symptoms to lasting relief.

Treatment Options for Post-Nasal Drip

Treatment of clear nasal drip is dependent upon the cause of the condition.


Septoplasty for Deviated Septum

The nasal septum is made up of bone and cartilage with overlying mucosa and divides the two nasal cavities. When the septum is significantly deviated (crooked), Dr. Allen can perform a septoplasty to straighten and correct its shape, restoring normal airflow and function when needed.

Sinus Infection

Treatment of sinus infections may include decongestants, antihistamines, nasal saline irrigation, steroid nasal sprays, antibiotics, and other medications. In cases where chronic sinusitis does not respond to medications, Dr. Allen may perform surgery. Surgical treatment of chronic sinusitis may include septoplasty as well as endoscopic sinus surgery.

 

In-Office Balloon Sinuplasty

This in-office procedure is performed to dilate the sinuses, allowing Dr. Allen to rinse them and clear them of debris while improving their drainage and function.

Endoscopic Sinus Surgery

During endoscopic sinus surgery, Dr. Allen is able to enlarge the sinus openings, clear nasal obstructions such as polyps, and create a more favorable environment for the application of topical sinus medications.

Inferior Turbinate Reduction

Turbinates are structures inside the nasal passages that cleanse, warm, and humidify air breathed through the nose. When enlarged turbinates cause nasal obstruction or chronic congestion, inferior turbinate reduction (turbinoplasty) can significantly improve nasal airflow.

Allergies

In cases where allergies cause postnasal drip, treatment may include allergy pills, allergy shots or drops (immunotherapy), antihistamine nasal sprays, decongestants, and/or nasal or oral steroids.

 

Infection

When a bacterial infection causes postnasal drip, antibiotics are prescribed. Additional treatment may include saline nasal irrigation, decongestants, and/or nasal spray. When these medical treatments fail, surgery may be required to clear chronic infections.

Frequently Asked Questions

Is Post-Nasal Drip Serious?

Not always, but it can significantly impact your quality of life when it becomes chronic. It may also signal underlying issues like sinusitis, allergies, or reflux, which should be properly addressed.

Can Allergies Cause Post-nasal Drip Year-Round?

Yes. Perennial allergic rhinitis, often caused by indoor allergens like dust mites or pet dander, can lead to year-round postnasal drip symptoms.

How do I Know if I Have a Post-Nasal Drip or Just a Sore Throat?

Postnasal drip often causes a scratchy throat that worsens when lying down, along with throat clearing, a runny nose, or a “tickle” in the back of the throat. A sore throat from infection usually comes with other signs like fever or swollen glands.

Can Post-Nasal Drip Cause Bad Breath?

Yes. Excess mucus in the throat can attract bacteria that cause halitosis (bad breath). Treating the underlying cause can improve both your symptoms and breath.
