Post-nasal drip (PND) occurs when excessive mucus is produced by the sinuses. The excess mucus accumulates in the throat or back of the nose. It can be caused by rhinitis, sinusitis, or laryngopharyngeal acid reflux. It can be enhanced or sometimes even caused by allergies, whether in spring, fall or early summer.

[edit] Terminology

The term PND is considered obsolete by some sources and is now referred to as "Chronic Upper Airway Cough Syndrome".[1] However, the term "post-nasal drip" is still used in modern medical literature[2][3], though some do not consider the term to be well-defined.[4]

[edit] Associated conditions

PND may be, in some cases, a contributing cause for halitosis - bad breath arising from the posterior tongue dorsum. [5]

[edit] Symptoms

An individual may be diagnosed as suffering from post-nasal drip if they suffer from the following symptoms.

[edit] Treatment

A person seeking treatment for post-nasal drip should see an otolaryngologist or family physician. For minor relief, drinking plenty of fluids, particularly hot water, can help.

Treatment may include antibiotics, nasal irrigation, or minor surgery.

Some people use bulb syringes, squirt bottles, and neti pots for nasal irrigation. Others use pulsating irrigation devices that deliver an intermittant pulsing saline rinse to remove bacteria, purulent material, and help restore ciliary function.

Many published medical reports indicate pulsatile lavage is more effective at cleansing and removing bacteria than non-pulsating nasal wash products like bulb syringes, neti pots and squeeze bottles, which rely simply on gravity and conventional flow. [7] [8] [9]

A pulsating nasal irrigation device delivers a controlled flow with pressure control that may be adjusted for individual comfort. Medical reports support that positive pressure irrigation retains a larger volume of solution and irrigates the sinuses more consistently than other methods. [10]

Other treatments, for the allergy aspect of the disorder, include the usage of antihistamines and/or decongestants to treat the most common effects. Steroids may also be prescribed for short-term usage, as extended use may cause harmful side effects.

A recent study has also shown that physiotherapy of the nasopharynx has been successfully employed to achieve a quick and effective treatment of symptoms [11].
