I was in pain around my jaw and throat but I thought that must be normalAmanda Walker Ms Walker, who has an 11-year-old son named Louis, at first did not realise the severity of the situation.She said: “I was in pain around my jaw and throat but I thought that must be normal. In the immediate aftermath of the operation I was taking ibuprofen so that masked some of the pain.”Days later I knew that it wasn’t right. I was still in a lot of pain. But at that point I didn’t even connect the pain in my jaw with the operation. It was only when I went to see my dentist and I was told the amount of damage that I started to put two and two together.”I was in total shock to think this could have happened.” She had to live on a diet of bananas and soup The last thing she expected following the procedure was to be enduring years of agonising pain in her jawRoss McWilliams, medical negligence lawyer Ms Walker has had to go through numerous operationsCredit:Christopher Furlong /Getty Ms Walker, from Knarsborough, North Yorks., has received a payout between £100,000 and £400,000 and a written apology from the hospital.She said: “It turned out that during the operation I had not been given enough anaesthetic so I started to come around mid-procedure.”In her panic to rectify the situation the anaesthetist used a Laryngeal mask – a medical device that keeps a patient’s airway open during anaesthesia or unconsciousness – designed for a 25 stone man, forcing it down my throat.” In April 2011 Ms Walker’s jaw was drilled and forcefully flushed out to try and align the joints – but this only worked on her left-hand side.She had the same procedure in August of that year but again it did not work. The following month she had open surgery to shave away bone on the right side of her jaw, but once more it did not work.In the meantime, Ms Walker was in immense pain and was only able to open her jaw a tiny 2cm – if she tried to move it any more than that pain would shoot through her face.In May last year Ms Walker had a partial titanium jaw replacement at Bradford Royal Infirmary, West Yorks. Ross McWilliams, an expert medical negligence lawyer at Irwin Mitchell, who represented Amanda, said: “Amanda has had an extremely difficult time over the last five years. She went into the hospital at a very distressing time for her, shortly after a miscarriage, and the last thing she expected following the procedure was to be enduring years of agonising pain in her jaw.”She is determined that the Trust and staff at the hospital learn from what happened to her. She was left in agonising pain that completely turned her life upside-down and she needed extensive facial surgery to correct the problems she suffered as a result of her dislocated jaw.”Amanda is aware that there she is likely to need further surgery in the future, which is obviously causing her a great deal of anxiety.”We are glad that the Harrogate & District NHS Foundation Trust has finally admitted liability for the injuries Amanda suffered and agreed a settlement with her.”However, the Trust denied responsibility for what happened to her for four years, which caused a great deal of distress and prolonged the litigation unnecessarily for someone who has been desperate to put this terrible ordeal behind her and begin to get her life back on track.”No disciplinary procedure was ever brought for the anaesthetist reponsible for the damage.Dr David Scullion, Medical Director at Harrogate and District NHS Foundation Trust, said: “The Trust is pleased that an agreement has been reached. We have apologised to Ms Walker for the impact this injury has had on her, and I would like to reiterate that apology now.”We conducted an investigation into Ms Walker’s care with us in 2010 and want to give assurance that we have learned all we can from this incident.” A mother-of-one has received a six figure payout after a botched operation left her unable to open her mouth wider than 2cm for five years.Amanda Walker lived on a diet of soup and bananas, had difficulty talking and laughing and was in constant pain after a doctor dislocated her jaw while fitting breathing apparatus during a procedure.The 48-year-old had started to come around during a routine womb operation at Harrogate and District NHS Foundation Trust Hospital just days before Christmas in December 2010 which she needed as she had miscarried twins.The anaesthetist used excessive force when fitting a special mask to keep her airway open dislocating her jaw.
