It was reported the patient has experienced multiple issues with her bilateral temporomandibular joint prostheses since implantation thirteen years ago.The patient reported symptoms and procedures including nerve damage, neuroma removal, x-rays, botox injections, ct scan, pain, difficulty chewing, difficulty eating and a planned revision.The patient reported the nerve damage occurred immediately after implantation which resulted in her being unable to blink her right eye or move her right eyebrow.The patient reported a neuroma was removed from the right side of her jaw seven years ago.The patient reported she had x-rays taken by a dentist and was informed that a screw on the right side is not intact.The patient reported receiving botox to her face approximately one year ago to treat pain, but stated that it did not provide relief and aggravated the pain further.The patient reported a ct scan was taken four months ago and revealed that two screws on the right side were not intact and were not stable.The patient reported she has excruciating pain, difficulty chewing, and difficulty eating.She stated due to the difficulty eating, she chokes on her food.Additionally, she reported there is discomfort on the left side which is aggravated by bad weather but the issues are not significant.The patient reported there is a revision planned to remove the implants on her right side, but the date is not yet set.
