A young Vietnamese girl is set to undergo a life-changing procedure at Adelaide's Women's and Children's Hospital.

Two-year-old Lam Ngyuen suffers from Crouzon Syndrome, which affects the development of the skull.

The genetic condition stems from an abnormality during embryonic development.

Dr Xenia Doorenbosch, a neurosurgeon at the hospital, said the surgery is important to ensure Lam's survival.

"It can affect their development, it can also be life-threatening," she said.

"It affects their vision as well, there are kids that have gone blind."

A team of doctors will perform two surgeries on Lam, the first will create more room at the rear of her skull, before another procedure two weeks later, to allow her brain to develop as she grows.

The procedure is one of 15, that surgeons will perform pro-bono. Picture: Supplied (Supplied)

Lam's mother, who has travelled to Adelaide with her daughter, says the procedure will give her a better quality of life

"I just hope after the surgery, that she can go to school as (the) other children," she said.

The surgery is part of a humanitarian program operated by the hospital's craniofacial unit, which performs 15 procedures on international patients - free of charge - every year.

"It's great that we can help patients not just from Australia, we're very fortunate that we can have access to a specialised unit," Dr Doorenbosch said.
