Thank you for your question and I'm sorry to hear about your recent burn on your left hand.
Burn wounds run a whole gamut in terms of complexity - entire books have been written on the management of burn injuries. Therefore, management of burn wounds should be undertaken by someone with the relevant experience and training in this subject matter in order to have the best cosmetic and functional outcome.
Management starts from the acute phase of the burn injury, in order to minimise the extent and morbidity. However, that is no longer relevant to you as it is probably now beyond the first 1-3 weeks of injury.
In terms of long term management of burn injuries, it boils down to optimising the cosmetic outcome and reducing any functional deficits. For the cosmetic aspect, it usually involves the colour and the texture of the scar.
The treatments already mentioned by the other doctors are reasonable options for matured burn scars. In terms of functional deficits, surgical options such as scar revisions, scar releases with Z-, W-plasties or skin grafts may be required. This is medical in nature and can be covered by Medisave and Insurance.
Thank you and best regards,
Dr Samuel Ho
