HIGH SCHOOL MUSICAL star Ashley Tisdale has become the latest celebrity to undergo rhinoplasty to treat a deviated septum. Jennifer Aniston and Cameron Diaz have both had the nose problem corrected this year (07), and now 22-year-old Tisdale reveals she had the five-hour procedure at a Los Angeles hospital on Friday (30Nov07). She tells People magazine, "Growing up I always knew I had a deviated septum on the right side of my nose, which caused trouble breathing. "The older I got, the worse it got. I went to get it checked out, and the doctor told me the septum was 80 per cent deviated and that I had two small fractures on my nose." Tisdale hopes her operation won't encourage any of her fans to opt for cosmetic surgery. She adds, "I didn't do this because I believe in plastic surgery. I did this to help my health. I literally almost could not breathe out of the right side of my nose."
