Background: Burn injury is considered as one of major problems because of high mortality and morbidity, not only due to improper treatment of burn resuscitation during the first 24 hours, but also the extent and depth of burns. The right depth of the wound determines the next action whether the burn will be excised or not. Determining the depth of burns clinically is a learning curve and less accurate because it depends on the experience of the surgeon. A method is needed to make clinical assessment objectively in determining burn wound depth.

Methods: We did clinical and thermography assessment using Flir One thermal imager to determine the conversion of burn depth of the patient before & after the excision and after the skin grafting. Subsequently, temperature differences between the burn wound and healthy skin (delta T) were measured and compared before and after the excision.

Results: We performed clinical and thermography assessment in 3 patients, age range 25-48 years old, burn size 7.5% - 41% TBSA. Two patients showed low temperature (temperature of burn area: 34.2C, T: -2.2C) so we decided to excise it. After the surgery, it shows that the temperature increase (temperature of burn area: 32.7C, T: -0.5C), that indicated the improvement of the circulation. One patient showed an area of burns with an average temperature (temperature of burn area: 36.9C, T: 2.2C). We decided not to excise and epithelialization was observed on the 7th-day post-burn. 
	
Conclusion: Thermography assessment such as Flir One thermal imager can be utilized to determine the depth of burns in addition to clinical assessment. It benefits not only for the functional purpose but also affordable price and practically used. In the future, it may be useful to help both experienced surgeons and novices.
