People with an unsightly scar tissue condition may benefit from a new combination treatment, says the surgeon who developed the therapy.
The technique, which involves freezing, can treat keloid an overgrowth of scar tissue that develops around a wound said Tony Chan Tung-fei.
Chan said he started using the technique earlier this year and has treated 10 patients so far. But it is not cheap, at HK$10,000 to HK$20,000 per keloid.
This helps to reduce by half or two-thirds the size of the keloid. The earring suppresses capillaries so oxygen is not generated. "There is a 70 percent chance of keloid not recurring with the magnetic compression and cryotherapy. So far no patient has shown signs of recurrence," Chan said.
Patients should wear the earring for eight to 12 hours at a time.
Steroids have been used to treat keloid but that carries a 90 percent recurrence rate.
Many choose to undergo surgery but during recovery the scar might become larger, he said.
A keloid sufferer, Ms Lo, 27, from Macau, had her ears pierced 10 years ago. A year later, her ear became inflamed.
"I consulted the doctor in Macau and underwent surgery three times but it kept recurring," she said.
"It looked so ugly I covered it with my hair all the time."
Lo started cryotherapy last year and now the swollen part of the ear is nearly flat. She also had steroid jabs to minimize the chance of recurrence.
Since June Lo has used magnetic compression, wearing the earring for four to five hours a day. The keloid has not come back.
