1. The inner ends of the Eustachian Tubes lie just below the eyes and behind the nose. The outer end of the Eustachian Tube in the middle ear is bony and does not have any moving part. The inner end is made up of cartilage
and muscles which are also attached to the muscles of the palate
2. Opening an closing of the Eustachian Tubes can give rise to clicking sounds in the center of the
face. So can contractions of the muscles forming the soft palate. Myoclonus
is involuntary muscle spasms which may also cause clicking sounds in the same region.
3. The nasal skeleton (framework) is made up of multiple cartilages and can also give rise to crackling sounds. Mucosal contact and release, shifting secretions and blocked sinuses
can also cause passive sounds.
4. I would also like to know the following:
1. Did clenching your jaw induce or reduce the clicking noise?
2. Have you ever noticed your soft palate twitching if you open your mouth while looking at a mirror?
3, Does steam inhalation make you uncomfortable and leave you feeling stuffy?
4. Is it possible for me to review your CT/MRI
images? This will help to give an accurate assessment of the Lt. Maxillary Sinus Polyp.
I must emphasize that these clicking noises are a normal phenomenon and not a cause for worry.
