Improving Patient’s Quality of Life with a Bespoke Laryngeal Prosthesis

This case took place in 2017, when Dr Siti Radhziah (Consultant, Department of Otolaryngology at the Singapore General Hospital) approached AuMed (previously known as Creatz3D Medical) to create a customized Laryngeal Prosthesis for one of her patients.

In his late 60s, the patient had undergone a laryngectomy and suffered from chronic crusting of the stoma without other complications. The patient tried on several commercially available stoma plugs, but they worsened the wound around the stoma and impeded the recovery process.

Dr Siti noticed that the standard stoma plugs were either too large or too wide for the patient’s stoma, causing unwanted stretching on the skin and further resulted in crusting, irritation and sometimes, pain. The elderly patient did not know what else that he could do to stop the suffering.

Apart from receiving the patient’s MRI, AuMed also engaged external professionals to perform optical scanning of the patient various positions – to obtain the structural information of his larynx anatomy in supine, sitting and Fowler’s positions.

The team designed a prosthesis which recovered both the (1) exterior and (2) interior of the missing tissues. Which means, (1) the stoma outline was properly covered by the prosthesis and (2) the liquid swallowed by the patient was guided to the esophagus and has avoided the trachea.

Besides no more irritation on the stoma, the wife of the patient said that it has been a while since she last saw him happily drinking his favorite drinks from the mouth.
