Can the doctors/nurses access the cranial nerves or other major nerves through the incisive canal/incisive foramen or any other opening in the palate?
I believe the oral surgeons injected into the incisive canal/incisive foramen area. Are there cranial nerves or other major nerves in this area?
Common injection: The nerve in this area is the nasopalatine nerve. It is an accessory nerve of the maxillary branch (v2) of the trigeminal nerve (the 5th cranial nerve). It gives feeling to the palatal gingiva (gums on the roof of your mouth) behind your 4 upper front teeth. It is an extremely common injection and risk of complications are extremely low, but the injection itself is painful. ...Read moreSee 1 more doctor answer
Is there any reason why the health care agents will inject any liquid into the incisive foramen for #1 wisdom tooth extraction?
Ask the practioner: Local anesthesia may be injected into the incisive foramen to numb the upper front teeth and palate in that area, along with infiltration on the facial aspect. Personally, i see no reason why someone would do that for the removal of a wisdom tooth. If that was done, and you want to know why, i suggest that you ask the dentist. ...Read moreSee 1 more doctor answer
Normal hole: A foramen ovale is a normal opening between the upper chambers of the heart. It is present in every normal fetus to allow blood with oxygen to get from the placenta to where it needs to go in the fetus's body. This opening usually closes after birth, but is present in about 20% of all adults. It has been associated with some forms of stroke, migraine headaches, and decompression illness. ...Read more
Porthole in atria: Everyone has a patent foramen ovale that is closed by a flap of tissue that keeps blood from flowing from one atria to the other. Sometimes it stays open a little longer than average and allows some blood to circulate right to left or vice versa depending upon other clinical conditions. The foramen usually closes w/o any intervention. ...Read moreSee 1 more doctor answer
A normal structure..: ...In newborns, it allows proper circulation in the fetus by shunting blood coming from the mother's placenta to the left side of the baby's heart, which is pumped immediately out to the body. Nearly all infants have this structure still open when they are born, which usually close within weeks to months after birth. A small percentage of adults still can have an open foramen ovale, however. ...Read moreSee 1 more doctor answer
Usually nothing: 20-25% of all adults have pfo. Most live thier entire lives without problems related to the pfo. Some people have strokes that are thought to be related to pfo, and it has also been associated with migraine headahces and decompression illness in scuba divers. There is no evidence to indicate that pfo should be treated unless a person has problems thought to be directly related to the pfo. ...Read more
Normal: Probably about 20% of adults have a probe patent foramen ovale (pfo.) in the great majority of these people it appears that there are no consequences. Pfo has been implicated in causation of strokes or migraine headaches in some patients, but the data on this is conflicting, and the best treatment, if this is occurring, is unclear. Pfo without symptoms does not require special care. ...Read more
Likely nothing: Following birth there are changes in the heart and blood vessels. The ductus arteriosis which shunts blood away from the lungs, closes, as does the ductus venosis, the foramen ovale which is a normal hole in the upper chambers of the heart which sends oxygenated blood returning from the placenta also closes, but this happens over time as it functions as a valve. Rarely these have to be closed. ...Read more
Small heart opening: It is an opening in the wall between the upper chambers of the heart that allows blood from the placenta to get to where it needs to go during fetal life. All babies are born with this. It usually closes after birth, but 20% of all adults still have this. It is normal, though it has been associated with stroke, migraine headach, and decompression illness in scuba divers. ...Read moreSee 1 more doctor answer
