Transcripts: 557-4 & 557-5
Week: 557.4 Guest: Dr. Gary Hack, DDS, Prof. of Dentistry, U of MD. Dental School Topic: A newly discovered neck/brain connective tissue, Part 1 of 2 Producer/Host: Steve Girard
NEMA: New anatomical finds...coming up...
SPOT: 15 years in the prevention of heart disease, stroke and trauma - the National Emergency Medicine Association. Call 800-332-6362.
NEMA: A new muscular discovery... Dr. Gary Hack is a professor at the University of Maryland Dental School...his investigation has turned up a connective tissue between the neck and the sac which surrounds and protects the brain...
HACK: This structure...this bridge that goes from the muscle to the dura, is in an area right at the base of the skull. The function of this connection may be that in backward head movement, contraction of the neck muscles could pull on the dura, through this connective tissue bridge, and prevent this kinking of the dura that may compromise cerebro-spinal fluid flow.
NEMA: Perhaps it may contribute to headache pain?
HACK: We're beginning to get some reports that people who have had this structure cut, are now experiencing less headache pain than they had before the procedure was done.
NEMA: Dr. Gary Hack is a dentist, yet his interest in anatomy has resulted in finding two new structures that lend insight into the mechanisms and problems of our head and neck. I'm Steve Girard for The Heart of the Matter!
Week: 557.5 Guest: Dr. Gary Hack, DDS, Prof. of Dentistry, U of MD. Dental School Topic: A new facial muscle found, Part 2 of 2 Producer/Host: Steve Girard
NEMA: A new muscle for your face..coming up...
SPOT: For 15 years, the National Emergency Medicine Association has worked against stroke, heart disease and trauma. Join the effort, call 800-332-6362.
NEMA: One of the discoverers of a new connective tissue between the neck and the brain sac, Dr. Gary Hack has also found a muscle in the face which eluded generations of medical anatomists...
HACK: What we have found is a muscle which is not described in anatomy textbooks. We know that there are four known muscles - chewing muscles, muscles that move the jaw in chewing, and we believe that this may be a fifth muscle of mastication.
NEMA: What's it's job?
HACK: This new muscle, the sphenomandibularis, may indeed have something to do with retro-orbital pain, that is pain behind the eye in people who suffer from temporomandibular disorders. We're beginning to look at what the potential is...that this structure, that we never knew existed before, may indeed play a role in some of those types of headaches.
NEMA: Dr. Gary Hack, despite his obvious talents in his dissecting hobby, is a dentist and instructor at University of Maryland Dental School. He hopes his stumbling in the area of anatomy will send a message that there's always a chance to find something new. I'm Steve Girard for The Heart of the Matter!
