A doctor has been referred to the Medical Council after a young man was left with a paralysed shoulder from having a lump cut out of his neck.
Health and Disability Commissioner Anthony Hill has found the doctor breached the code of consumer rights and said he should never have attempted to remove the lump.
"He was operating beyond the scope of his confidence," Mr Hill said.
"He accepts that he was. He had done some minor surgery but he had not done anything of this complexity and he should not have undertaken this procedure."
Mr Hill said the patient had had subsequent surgery to repair the damage but his movement was still affected.
