Instagram to announce that she had to have emergency surgery on her oesophagus. After the horrific attack on the now 38-year-old, Piper was put into an induced coma for 12 days.
Using skin grafts and a plastic face mask, which she wore for 23 hours a day, the entire surface of the model's face was reconstructed.
After more than 400 surgeries Piper has had her face and vision restored, but after a recent incident where the star choked on a piece of food, the star required yet further surgery.
In a social media post to her one million followers, Piper explained why she was rushed to A&E. She wrote: "SO, last night I choked on some food which led to spasms in my oesophagus, which meant it closed up, meaning I couldn't swallow even my own saliva and ended up in A&E for an emergency procedure on my oesophagus (not the way to start a week). "I've got a long history of treatment with my oesophagus, I've got three strictures of tight scar tissue from what happened previously and this is something I've been aware of but hasn't happened in years. "But, out of surgery and it went very well and I just ate ice cream which felt heavenly!"READ MORE: High blood pressure: The drink that could 'significantly' reduce blood pressure in weeksImmediately the star's comments were filled with concerned members of the public, who showed support for Piper's hospital experience.
