METHODS OF IMPROVING CRANIOFACIAL PAIN AND STROKE RECOVERY
Methods of improving craniofacial pain or stroke recovery via neurostimulation are provided. Methods include first screening the subject for neurostimulation based on the subject's responsiveness to a block of the sphenopalatine ganglion or branch thereof.
1 . A method of improving craniofacial pain in a subject suffering therefrom comprising:
applying an anesthetic to a first dorsonasal structure of the subject;
determining if application of the anesthetic results in an improvement in craniofacial pain;
identifying the subject as a candidate for neurostimulation upon a determination that application of the anesthetic results in an improvement in the craniofacial pain;
placing a neurostimulator adjacent to a second dorsonasal structure upon an identification of the subject as a candidate for neurostimulation;
activating the neurostimulator to deliver a therapy signal to the second dorsonasal structure; and
improving the subject's craniofacial pain via activation of the neurostimulator.
2 . The method of claim 1 , wherein the first dorsonasal structure and the second dorsonasal structure are the same structure.
3 . The method of claim 1 , wherein the first dorsonasal structure and the second dorsonasal structure are different structures.
4 . The method of claim 1 , wherein the neurostimulator is an electrical neurostimulator and the therapy signal is an electrical signal.
5 . The method of claim 1 , wherein the neurostimulator is a drug delivery device and the therapy signal is a chemical signal.
6 . The method of claim 1 , wherein the dorsonasal structure is a sphenopalatine ganglion.
7 . The method of claim 1 , wherein the identifying step comprise identifying if the subject is a candidate for implantation of a neurostimulator and wherein the placing step comprises implanting the neurostimulator adjacent to the second dorsal nasal structure.
8 . The method of claim 1 , wherein the determining step comprises determining if application of the anesthetic results in a short-term improvement in the craniofacial pain.
9 . A method of improving stroke recovery in a subject who has suffered from stroke comprising:
applying an anesthetic to a first dorsonasal structure of the subject;
determining if application of the anesthetic results in an improvement in the stroke recovery;
identifying the subject as a candidate for neurostimulation upon a determination that the application of the anesthetic results in an improvement in the stroke recovery;
placing a neurostimulator adjacent to a second dorsonasal structure upon an identification of the subject as a candidate for neurostimulation;
activating the neurostimulator to deliver a therapy signal to the second dorsonasal structure; and
improving the subject's stroke recovery via activation of the neurostimulator.
10 . The method of claim 9 , wherein the first dorsonasal structure and the second dorsonasal structure are the same structure.
11 . The method of claim 9 , wherein the first dorsonasal structure and the second dorsonasal structure are different structures.
12 . The method of claim 9 , wherein the neurostimulator is an electrical neurostimulator and the therapy signal is an electrical signal.
13 . The method of claim 9 , wherein the neurostimulator is a drug delivery device and the therapy signal is a chemical signal.
14 . The method of claim 9 , wherein the dorsonasal structure is a sphenopalatine ganglion.
15 . The method of claim 9 , wherein the identifying step comprise identifying if the subject is a candidate for implantation of a neurostimulator and wherein the placing step comprises implanting the neurostimulator adjacent to the second dorsal nasal structure.
