Is orbital CT scan and CT scan sinus the same?

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Netty pot: Dr. Hamid answer is excellent. If you think that it is coming from your nose, try the netty pot. Get at drug store. It is a small tea pot that you place hot salt water into it, then irrigate your nose with the water. In one nostril, then the other. Flushing out any impurities, etc. Can't hurt while you are waiting for the other tests. ...Read more

Maybe: First, continue with your oral decongestants (loratidine, claritin, or benadryl), and also try Afrin nasal spray. If that doesn't help, you may need to see a physician. A short course of oral corticosteroids may help (prednisone, Medrol Dospak, etc). ...Read more

Can ent dr see if u have etd by checking ears or only thru a ct scan of sinus and ears?

ETD?: Eustachian tube dysfunction? Diagnosis can often by made by interview alone as symptoms/clinical course are typical. Aseptic swelling of the middle ear compartment (seen on ear exam) is supportive. CT scan will not help. If severe, and optimized treatment strategies for allergic or non-allergic rhinitis, gastric reflux, etc fail; then ENT will sometimes place ear tubes. ...Read more

Got nose CT scanned with sinus, it shows left concha bullosa and cyst in right sinus. I have post nasal drip. Are these symptomps of sinusitis?

Got nose CT scanned with sinus, it shows left concha bullosa and cyst in right sinus. I have post nasal drip. Are these symptomps of sinusitis?

Possible: A concha bullosa is an air containing middle turbinate (a normal structure in the lateral wall of the nose. This may be a normal anatomical variant unless the cat scan demonstrates it is opaque (filled with mucus). Depending on of the size of the cyst in the sinus, probably maxillary), I would definitely call this a rhino-sinusitis. Symptoms are complaints. Your statement is x-ray findings. ...Read more

If sinus CT says, both sinus are patent, what does the word patent mean pls, my symptoms are nasal congestion, dryness, and trouble vid nasal breathin?

Patent = Open: In the context of you sinus ct — patent means that your sinuses are open and unobstructed (that's normal). In regard to your symptoms, you should have a discussion with your ENT doctor regarding why you are having difficulty with nasal breathing and nasal congestion. ...Read more

Tightness behind ears and inside ears that comes and goes. Pressure of middle ear is fine and CT sinus scan doesn't show any issues with ears. Thoughts?

Sounds like TMJ: There are many symptoms related to the ear area that occur when the jaw joint (also known as the temporomandibular joint — TMJ for short) is out of position, inflammed, degenerated, or traumatized. Often times the TMJ clicks, pops, or is tender when you put your finger into the ear canal and open and close your jaw. Splints and specialist care should be considered before it gets worse. ...Read more

Would a ct scan and sinus scan show labyrinthitis? Or lack of blood flow to brain?

Would a ct scan and sinus scan show labyrinthitis? Or lack of blood flow to brain?

Doubtful: A standard CT scan of the brain would have challenges in determining inner ear issues or blood flow per se. Additional modifications would be needed for the latter (along with the appropriate clinical symptoms), and other types of scans would be better for evaluation for the former (e.g. MRI, again, with the appropriate symptoms). ...Read more

Got a mucus retention cyst in sinus CT scan blocking sinus partially. What are the treatments to remove it or dissolve it? Suffering from post nasal dip

Not necessary to: Remove a mucous retention cyst is not necessarily the cause of your sinus problems. I take ct scans all day and we see a lot of mucous retention cysts with little correlation to symptoms. If you are going to have it out just know that your symptoms will probably not improve. Many university radiologists that read scans will advise against treatment because of the high reoccurrence rate ...Read more

How can I unblock my sinuses so l can sleep better at night. I blow my nose nothing come out. Ct showed inflammed sinus 1side. Told use saline spray.

ENT assistance: You might well need the expert advice and treatment of an ENT-Ear, Nose and Throat specialist. For sinuses that are diseased like that, saline spray is a good first line therapy. You might want to try sleeping at something of an incline, since the gravity can help drain the sinus. You may need anti-inflammatory medications too, to get the swelling to go down so things can drain. Follow up with doc ...Read more

Can deviated septum with prominent spur and nasal valve collapse cause recurrent sinus infections even if CT scan said sinus were well ventilated?

Can deviated septum with prominent spur and nasal valve collapse cause recurrent sinus infections even if CT scan said sinus were well ventilated?

Deviated septum: A deviated septum is not an uncommon problem. It can lead to nasal obstruction, snoring and even sinus issues. You only need surgery if you are having symptoms. If there are symptoms like nasal obstruction, snoring or recurrent sinusitis, have your nose evaluated by a board certified otolaryngologist. ...Read more

Lt side facial swelling/pain x 1 wk.  All teeth on lt hurt 1st 2 days, now no teeth pain.  Ct sinus showed soft tissue swelling.  Will prednisone help

Get diagnosis done: If you had swelling for a week most likely came from an infected tooth. Sinus may be inflamed related to an infected tooth. My advice is to go to an endodontist first and have a cb ct scan. If there is no tooth infection then go to an ent. ...Read more

Had CT scan for sinus/ear. Ent said it's clear. I looked at report it said I have a protuberant cavernous carotid artery covered by bone. What that mean?

Had CT scan for sinus/ear. Ent said it's clear. I looked at report it said I have a protuberant cavernous carotid artery covered by bone. What that mean?

Large vessel: The carotid arteries travel through the cavernous sinus which is a venous drainage system covered in part by bone. I think that they are pointing out that the cavernous carotid artery is confined in bone. If the artery breaks through the bone, it is said to be dehiscent--this can lead to big nose bleeds. ...Read more

If problem fails to improve after 3-4 days, you may need a different antibiotic. ...Read more

Both: Each of those studies cover a different part of the part of the brain and sinuses that are responsible for smell. The radiologist should be able to Taylor the study as needed. But sinus CT cannot visualize the entire brain to make sure nothing is abnormal there ...Read more
