[Treatment of scar contracture abnormality on the neck of the children with huge trapezius muscle flap expanded].

OBJECTIVE: To seek a kind of safe and effective method to treat scar contracture abnormality on the neck of the children. METHODS: We take the trunk line of transverse cervical artery as the vessel pedicle, and shift huge trapezius muscle flap expanded to the neck in order to treat scar contracture abnormality on the neck of the children. RESULTS: Clinically, we applied this method to treat ten children who suffered from contracture abnormality on the neck, and not only provide enough skin soft tissue (the length may be beyond the midline) to treat the abnormality, but also make the flap alive, obtain the satisfying postoperative effect. CONCLUSIONS: Based on the warranty of the flap blood supply, this flap is very suitable to treat scar contracture abnormality on the neck of the children.

[Rejuvenation of the forehead/temple by limited incision].

OBJECTIVE: To utilize multiplane, subcutaneous and subperiosteal, dissection through small incisions in scalp to rejuvenate aging signs of forehead/temple. METHODS: Forehead: We make four small incisions in scalp, widely separate tissues between subperiosteum skin and frontal muscle to form galea frontal muscle-periosteum flap, the flap is tightened and sutured with the galea at the posterior border of the incision. This method avoid to excise scalp. Temple: there are two small incisions in the scalp of temple at each side. Superficial temple fascia and orbicularis oculi muscle as well is dissected from deep temporal fascia and skin respectively, then tightened and sutured with the superficial part of deep temporal fascia, excising scalp is not necessary. RESULTS: Twenty patients have received this treatment, the effects are satisfying. CONCLUSIONS: Multiplane dissection through small incisions can remove wrinkles of skin, correct the prolapse of eyebrow and avoid the complications of coronary incision. This approach brings more rapid recovery of patients, it is safe and affective.

[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.

[Studies on factors affecting velopharyngeal functions of cleft palate patients].

OBJECTIVE: To investigate the relationship between velopharyngeal functions and factors such as age at operation, cleft type, performing procedure. METHODS: FFT technique and velopharyngeal X-ray examination were used to evaluate the velopharyngeal functions of 82 patients. The relatively important factors affecting velopharyngeal functions were searched out through regression analyse and pearson correlation. RESULTS: A significant positive correlation was confirmed between AAO(age at operation) and A1/A2(velopharyngeal incompetence), P < 0.001. AAO also showed linear regression with A1/A2. Model was significant, P < 0.001. Quotation: A1/A2(velopharyngeal incompetence) = 0.005 852 x AAO + 0.961. CONCLUSION: AAO was an important affecting factor on velopharyngeal functions. The earlier the cleft is repaired, the more normal velopharyngeal functions will be obtained.
