Interplast has been sending teams annually to counter the tens of millions of people in the Asia/Pacific who do not have access to surgery.
In Tonga, a lack of medical resources and limited training means people with repairable conditions are not getting the care they need.
The surgeons will deal with patients who have conditions such as cleft lip and palate, burns scarring, hand injuries or tumours.
The Interplast team will be in Tonga in the last week of February and is encouraging appointments to be made at Vaiola Hospital.
