paranasal sinus

An air cavity in a facial bone, either the frontal, maxillary, sphenoid, or ethmoid bones; most paranasal sinuses occur in pairs. The paranasal sinuses are lined with ciliated epithelium that secretes mucus. The sinuses open into the lateral walls of the nasal cavities via small holes. Healthy paranasal sinuses are radiolucent.

Patient discussion about paranasal sinus

Q. My 21 year son has chronic sinus issues, I think, due to many high school sports injuries. Help! His ENT has recommended a "nose job" but our insurance will not cover it. Do you know of any holostic, nutritional or homeopathic solutions to keep this under control? When he gets a headache, it shuts him down and normally goes into a migraine.

A. One of the best, most inexpensive, ways to prevent, treat, and generally care for any sinus related problem is with a saline (salt water) sinus rinse. The one I use is called "Neil Med" and can be purchased at Walgreen's for about $15. It has a plastic bottle with pre-measured, pre-packaged salt that is should be mixed with cooled off sterilized (boiled) water. If I get an infection, using 2 or 3 packets to concentrate the solution gives the lavage a bacteriostatic (stuns/partially kills bacteria), not bacteriocidal (kills bacteria) quality. I do not own Neil Med although I wish I did!! The lavage method also washes out any dust, old mucous, you name it. It should be used prior to the use of any nasal steroid like Flonase if treating allergic rhinitis. Good luck!!

Q. I have been having chronic pain in sinus area and behind my eyes, been to ENT who states it is not infection? I wake up with the pain and go to sleep in severe pain. Its all day and all night. Dr insists that its migraine related and allergy related. I have chronic postnasal drainage. It started 4 months ago when I moved into our new house. The pain makes me extremely fatigue and dizzy at times. I have been referred to the eye doctor, a headache specialist and an allergy specialist. Just recently I have had a CT scan and an MRI, as well as xrays of my sinus. Nothing other than a deviated septum and possible allergies from an ENT has been diagnosed. In the mean time I am waiting for the days to come when I can get into see these specialist. Anyone out there have any of the same symptoms?? Need help here. Soooooo sick of the pain.

A. i have chronic sinusitis and can really relate to what you describe. learned to live with the pain...but still, i use various ways to reduce inflammation in my sinuses, i heat the place up before going to sleep, try to avoid eating or drinking cold stuff.
another thing i do is i heat water (80c) then add a special oil i bought in a chinese medicine store , about 5 drops, and inhale the fumes. nettle tea can do wonders too.

Q. sinus infection and Polups and I can't breath through my nose. What can I do?

A. I have used the expresso machine for the steam only and run that through a glass with some vics in it. Helped but the polups are so large now its hard to get any thing through.
