Brief Answer:
Polypoid mucosal thickening in sinuses is usually due to dust and allergy.

Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
The finding of polypoid mucosal thickening involving maxillary and ethmoid sinuses is a benign one. It happens usually due to allergic inflammation of the cells lining the sinus lumen.

If you have undergone a X ray and CT scan of the paranasal air sinuses (PNS) then please send across your report details for confirmation of location and size of the polypoid mucosal thickening for better understanding.

This finding might cause headache and nasal block in some patients. Taking anti allergy medications and avoiding dust usually helps treat this condition.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek
