I’ve been experiencing persistent post-nasal drip for a couple of months, exclusively on my right side. I had a sphenoidectomy on my right side about 4 years ago, and my nose hasn’t caused me much problems since, except for the recent post-nasal drip. I am using steroid nasal sprays twice a day and taking antihistamines from my GP (Zyrtec, Telfast or chlorpheniramine), but the post-nasal drip doesn’t seem to get better. Could this be related to the sphenoidectomy, or is it just rhinitis? What else can I do besides the spray and antihistamines?
Thank you for your question. Common causes of postnasal drip (sensation of mucous stuck in the back of the nose or throat) include:
- Conditions of the nose (e.g sensitive nose or rhinitis, sinusitis)
- Acid reflux to the throat (called laryngopharyngeal reflux)
In patients I’ve seen with similar history to yours, a one sided nasal congestion or postnasal drip may indicate an active sinus infection (sinusitis).
Since it has been ongoing for several months without relief from nasal steroid spray and antihistamine, and you’ve had previous sinus surgery (sphenoidoyomy), I would suggest consulting an ENT Specialist for evaluation.
Your ENT specialist will be able to perform a nasoendoscopy (scope through the nose) to examine the nasal cavity, previously operated sphenoid sinus and your voice box.
If you do have sinusitis, you will need a course of oral antibiotics, nasal douche (nose wash with salt solutions) in addition to the nasal steroid spray.
Hope this helps.
