[The applications of the repetitive sub-platysmal expansion in repair the defects of skin and soft tissue in face and neck].

Objective To study a new effective approach which repairs large defects of skin and soft tissue in neck and face . Method This procedure accomplishes repetitive sub-platysmal expansion to form large musculocutaneous flap with underlying pedicel. The surgeon slides it toward neck and face to repair the defects of skin and soft tissue. Result Eleven patients,who had such defects in neck,face,cheek,chin or submental skin and soft tissue,underwent this treatment. All the flaps survive with no complications of blood supply deficiency or necrosis. The short-term and long-term results are both satisfying. Conclusion This method,making repetitive sub-platysmal expansion to form musculocutaneous flap and then slide it toward neck/face to repair large defects of skin and soft tissue,proves to be safe and reliable. And appropriate cases and strict operations are important. ;
