21 December 2009As Oprah Winfrey is set to launch her own television network, leading surgeons are speculating that the television icon may have held back the years with cosmetic surgery. At 55 years old, and following several major weight gains and losses, Oprah still looks as good as ever, causing Make Me Heal to suggest that she may have used some of the plastic surgery procedures debuted on her prime time show.According to plastic surgeon Dr Anthony Youn, Oprah may have had a nose job in the past. The surgeon stated: "It does appear to me that her nose may have been thinned. If so, it is a nice job because it still retains her ethnicity, while at the same time refining her overall appearance." In more recent years, the star may also have used anti-ageing treatments such as Botox to retain her youthful appearance. Dr Paul S Nassif observes: "There is the possibility she has had a few fillers and some Botox. Overall, Oprah looks very natural. If there was a change, it is very subtle and the surgeon did an excellent job." Oprah recently announced that her popular talk show would end in September 2011 after 25 years. She told her live studio audience: "I love this show, and I love it enough to know when it's time to say goodbye. "Twenty-five years feels right in my bones, and it feels right in my spirit - it's the perfect number, the exact right time. "And until that day in 2011 when it ends, I intend to soak up every meaningful, joyful moment with you."
