Patients who have lost their voice box through disease such as throat cancer may be able to speak immediately after a procedure to create a small opening at the throat. A novel system developed through an Engineering-in-Medicine project led by Dr Chui Chee Kiong, NUS Department of Mechanical Engineering, and Dr David Lau, Consultant Ear, Nose & Throat (ENT) Surgeon at Raffles Hospital, cuts down a two-week duration before patients can speak, to about 10 minutes after the initial procedure.
