In maxillofacial plastic surgery, burn scars, traumatic defects and defects owing to the tumor extraction cover the wide skin of face.
The patients have formal and functional disorders, mental and psychological disorders because of the wide skin defects of face.
The local random skin flap, the main treatment method in plastic surgery has a little practical possibilities and free skin graft which is able to use a wide flap of skin has a lot of disadvantages.
Recently the idea of perforator skin flap is suggested with the development of anatomical study and skin flap technology and a basic study is being made to apply axial skin flap based on cutaneous nutritional vessels.
The department of facial plastic surgery, Pyongyang medical college of
We applied it to 20 patients who visited the department of facial plastic surgery, from March 2013 to March 2016. 8 cases of them are male and 12 cases female; age is from 19 to 46. Among them, 14 patients had post-burn defects, 3 patients' traumatic defects, 2 patients' buccal black spots and 1patient buccal simple heamangioma. The size of skin defect was 20㎝×8㎝. Medial upper arm axial skin flap was applied to 20 patients, all skin flaps were survived and they showed primary healing. After operation, the complications appeared in 2cases, they were temporary skin's blood circulation disorders but the colors of the flaps were gradually improved. It had no necrosis. The size of skin flap was from 20㎝×6㎝ to 12㎝×6㎝. Following observation for 2years showed that skin color and quality was similar to face and donor site was hidden.
We will make further clinical study to obtain the wider skin flaps by applying skin expansions and delay operations to medial upper arm axial skin flap, and increase the effect of plastic surgery.
