Hello doctor,

I was diagnosed with chronic sinusitis without polyps two years back. Then, I had congestion, pain, throbbing, postnasal drip, weak sense of smell and taste, dizziness, cough, tinnitus in my left ear, and eustachian tube dysfunction. My ENT suggested me to undergo a CT scan and scope. He said I had a mild disease in my maxillary and ethmoid sinuses only. No pus or infection and no blocked sinuses. He said I had a mildly deviated septum but that it does not require surgery. He prescribed me Budesonide rinses two times a day. I was tested for airborne allergies, but that test was negative. I do not have asthma. My symptoms are gone except for a weak sense of smell, tinnitus in the left ear, and very mild Eustachian tube dysfunction. I have had a good response to treatment. My questions are, does the sense of smell eventually return or improve? Sometimes my sense of smell fluctuates and improves but not for long. How often will chronic sinusitis return? Thank you.



Welcome to

Good to know that your symptoms have resolved. Most likely, you had an acute attack of sinusitis which has resolved now.

I suggest you to follow the instructions mentioned below to improve your sense of smell.

1. Smell training videos can be found online.

2. Omega 3,6,9 tablets (especially omega 3 - antioxidant) as a supplement once daily for atleast a month.

For tinnitus,

Do you have an issue with your sense of hearing too? I would suggest you to get a pure tone audiogram and tympanometry for evaluation.

I hope this has helped.

The Probable causes:


Eustachian dysfunction.

Investigations to be done:

Smell test.

Pure tone audiometry and tympanogram.

Differential diagnosis:

Eustachian dysfunction.

Treatment plan:

For anosmia, I have suggested supplements and smell training.

For tinnitus will advise once I get the test results.

Preventive measures:

Avoid forceful blowing of the nose.

Regarding follow up:

Follow-up in 15 days.
