A REVOLUTIONARY new form of surgery that allows brain tumours to be removed without making a single incision is set to transform the field of medicine. Traditionally, such operations involved surgeons opening the skull and delving downwards. Alternatively, parts of the brain were reached via large incisions in the side of the face or inside the mouth, all options that leave major scars. But pioneering brain surgeons at Sheffields Hallamshire Hospital have adopted a US-developed technique to reach deep-set tumours using an endoscope that is fed through the nose, reports the Daily Mail. Surgeons now hope the success of this operation will pave the way for other types of brain tumour to be removed without making a single incision. The tumour is reached by working through one nostril and making a hole in the back of the nasal cavity into the bottom of the skull. TD
