Brief summary
This study evaluates the effect of Expanded Pedicled Deltopectoral Flap on facial-cervical scars repair, including flap sensation, L\*a\*b\* value,flap's elasticity,melanin content, hemoglobin content, and evaluation of scar and patient, doctor, and third-party satisfaction
Detailed description
The scars of face and neck caused by burning often show as large faciocervical scar.Important areas of current focus in face and neck scars management are functional outcomes and quality of patient life.The deltopectoral flap was first described by Bakamjian in 1965, and was recognized as one of the first choices for facial reconstruction, as the texture, color of the flap skin is similar to the facial skin. Since the tissue expansion technique was used to the flap, the flap became one of the best choices for the facial defect reconstruction,especially for Asian patients. It can be used with pedicled or free transferred.Complications at the donor or recipient site have been widely reported and often include dilator exposure,the flap blood circulation disorder and delayed healing, but the pattern of sensory recovery ,flap's elasticitycolor change have been studied less well.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Flap Color（the value of L*a*b*） | 3 month later | The Antera 3D is a camera for image acquisition and analysis of the skin.Every color is expressed in a three-dimensional coordinate system in terms of three units. L\* expresses the luminance and gives the relative brightness of the color ranging from total black (L\* ¼ 0) to total white (L\* ¼ 100).The terms a\* and b\* are coordinates of chromaticity, with a\* representing the balance between green (negative values)and red (positive values) and b\* representing the balance between blue (negative values) and yellow (positive values) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Light Touch | 3 month later | The tactile sensation of the flap after surgery is assessed by Semmes-Weinstein monofilaments and the change in tactile sense is detected at least 3 months after surgery. |
| Two-point Discrimination（2PD） | 3 month later | Two-point Discrimination of the flap after surgery was assessed by Touch-Test discriminator, and changes in 2PD were detected at least 3 months after surgery. |
| Flap Elasticity | 3 month later | The elasticity of the flap after surgery was assessed by CK-MC960 and the change in elasticity was measured at least 3 months after surgery. |
| Temperature | 3 month later | Test tubes were equilibrated in water at 0◦C (cold) or 45-50 ◦C (warm) and applied for 5 s. |
| Hemoglobin Content | 3 month later | The hemoglobin content of the flap after surgery was evaluated by Antera 3D, and the change of melanin was detected at least 3 months after surgery. |
| Satisfaction questionnaire | 3 month later | At least 3 months after the patient's surgery, use a self-made satisfaction questionnaire to obtain patient satisfaction |
| Scar scaling | 6 month later | The scar around the flap after surgery was evaluated by Patient and Observer Scar Assessment and the scar was assessed at least 6 months after surgery. |
| Melanin Content | 3 month later | The melanin content of the flap after surgery was evaluated by Antera 3D, and the change of melanin was detected at least 3 months after surgery. |
