More tense operations are coming in the fourth episode of the BBC's Saving Lives in Leeds as surgeons tackle a rare tumour and a deep sarcoma.
One surgery is so complex only one surgeon in Leeds Teaching Hospitals Trust can perform it. Consultant Kenan Deniz will be operating on a rare tumour growing deep behind the ear of Maureen, 63.
Working alongside ENT surgeon, Sanjay Verma, Kenan will have to access the brain through the delicate structures behind Maureen's ear - and discovers it's stuck fast onto the delicate facial nerve. If he damages it during the surgery, Maureen's face will be left permanently paralysed.
