MEDICAL UPDATE
Energy in Medicine
By Wendy Braun
New devices utilizing laser energy and radiofrequency waves help reverse hearing
loss from chronic ear infections and target cancer cells for better cure rates.

“The CO2 laser has been utilized in middle ear surgery for the past two decades,” explains ear specialist Dr. Bob Owens of
Dallas, Texas, “But the OmniGuide BeamPath CO2 laser system allows an otologist (specialty ear surgeon) to hold the laser in a
handpiece. This creates the greatest degree of surgical precision that can be obtained while operating in a microsurgical
environment such as the middle ear space.”
Kayla, age 14, developed hearing loss from multiple ear infections that gradually immobilized tiny bones inside her ear. After
undergoing the new laser procedure, she no longer needs a hearing aid.
“Conductive hearing loss occurs when patients have scarring or bone growth that ‘tethers’ the eardrum or ossicles (small bones of
hearing),” Dr. Owens told the Post. “The OmniGuide laser divides the scar tissue and obliterates abnormal bone growth to free up
the structures and allow better conduction of sound to the inner ear.”
Patients with cholesteatoma (abnormal tissue in the ear), a perforated eardrum, or otosclerosis (abnormal bone in the ear) may
also benefit from the new laser surgery, according to Dr. Owens, who is one of the first doctors in the U.S. to use OmniGuide for
hearing loss in children.
The FDA-cleared system is also utilized for brain, throat, and GI tract problems. Click here for video clips of laser therapy in brain
cancer.

2. Radiofrequency waves
Calypso Medical’s “GPS for the body” uses tiny electromagnetic transponders to pinpoint the exact location of prostate cancer cells
during radiation therapy.
Experts know that organs in the body may shift during radiation treatments for prostate cancer. As a result, tumors may not
receive the optimal treatment dose and nearby urinary and rectal tissue may be damaged by unintended radiation exposure.
How the Calypso Works
1. Doctors implant 3 transponders about the size of rice grains into the diseased prostate.
2. Radiofrequency waves from the transponders communicate with external components of the Calypso System.
3. A display screen continuously monitors the position of the prostate gland during treatment and alerts the therapist when the
prostate drifts out of position.
Findings from a February 2010 study show that Calypso’s real-time tracking technology enabled physicians to direct increased
doses of radiation to the tumor while sparing surrounding tissue—a treatment strategy referred to as “margin reduction.”
“This is the first comparative study to show that margin reduction in prostate cancer radiation therapy has clinically significant and
measurable benefits in decreasing acute toxicity and short-term side effects,” said Dr. Constantine Mantz, radiation oncologist at
21st Century Oncology in Cape Coral, Florida and lead investigator of the study. “By reducing acute toxicity, we hope these
patients may also experience a significant reduction of long-term side effects.”
