RESUMEN
Objective:To investigate the effect of artificial dermis combined with KCI negative pressure suction device in the repair of scalp defect with skull exposure after the operation of scalp malignancy.Methods:From January 2016 to June 2018, 18 patients with scalp defect and skull exposure after scalp malignant tumor surgery were treated with artificial dermis combined with KCI negative pressure suction device.Results:Eighten patients had good wound healing after the first stage of surgery, and no infection occurred. The time for artificial dermis to complete granulation was 10-14 days, with an average of 12.1 days. After the second stage of skin grafting, the skin graft had a survival rate of 100%, with uniform color and good elasticity, without obvious scar hyperplasia or contracture. The postoperative follow-up period was 6 to 2 months, all the patients healed well without tumor recurrence, with good skin elasticity and friction-resistant, and they were satisfied.Conclusions:Artificial dermis combined with KCI negative pressure suction device is an effective and simple method to repair the scalp defect with skull exposure after tumor surgery.

Objective:To investigate the therapeutic effect of skull drilling and/or grinding combined with artificial dermis and vacuum sealing drainage in repairing scalp defects with skull exposure.Methods:From October 2014 to May 2018, 18 patients with scalp defect and skull exposure were treated in the Department of Burn and Plastic Surgery, the Second Clinical College of North Sichuan Medical College, including 10 males and 8 females, with an average age of 64 years (range, 34-86 years). The patients were divided into two groups: group A (by drilling skull or/and grinding combined with artificial dermis cover and vacuum sealing drainage plus two split thickness skin graft repair) and group B (by drilling skull or/andgrinding combined with artificial dermis cover plus two covering leather grinding stage split thickness skin graft repair), 9 cases in each group. The head wound granulation tissue, postoperative complications, skin graft survival rate and wound healing time were compared between the two groups. Vancouver scar assessment scale (VSS) was used to evaluate the wound healing in the two groups.Results:The time of granulation cultivation in group A and group B was (16.44±1.42) days and (29.11±13.32) days, the difference was statistically significant ( P<0.05); The wound healing time of group A and group B was (26.00±3.32) days and (40.67±14.37) days, the difference was statistically significant ( P<0.05); The postoperative complications of group A and group B were 1 case and 5 cases respectively, the difference was statistically significant ( P<0.05). The skin graft survival rates of group A and group B were (97.11±3.44)% and (95.00±4.74)%, the difference was not statistically significant ( P>0.05); The wound scar VSS scores of group A and group B were (7.67±1.32) points and (8.78±1.99) points, the difference was not statistically significant ( P>0.05). Conclusions:By drilling skull and/or grinding combined with artificial dermis cover and vacuum sealing drainage and two stage split thickness skin graft for repairing scalp defect with skull exposure wound can not only better scalp defect with skull exposure wounds, and reduce the postoperative complications, and significantly accelerate wound healing, but also can effectively improve the quality of wound healing, which is worthy of clinical application.
RESUMEN
Objective@#To explore the effects of anteriolateral thigh perforator flap and fascia lata transplantation in combination with computed tomography angiography (CTA) on repair of electrical burn wounds of head with skull exposure and necrosis.@*Methods@#Seven patients with head electrical burns accompanied by skull exposure and necrosis were admitted to our burn center from March 2016 to December 2017. Head CTA was performed before the operation. The diameters of the facial artery and vein or the superficial temporal artery and vein were measured, and their locations were marked on the body surface. Preoperative CTA for flap donor sites in lower extremities were also performed to track the descending branch of the lateral circumflex femoral artery with the similar diameter as the recipient vessels on the head, and their locations were marked on the body surface. Routine wound debridement and skull drilling were performed successively. The size of the wounds after debridement ranged from 12 cm×8 cm to 20 cm×12 cm, and the areas of skull exposure ranged from 8 cm×6 cm to 15 cm×10 cm. Anteriolateral thigh perforator flaps with areas from 13 cm×9 cm to 21 cm×13 cm containing 5-10 cm long vascular pedicles were designed and dissected accordingly. The fascia lata under the flap with area from 5 cm×2 cm to 10 cm×3 cm was dissected according to the length of vascular pedicle. The fascia lata was transplanted to cover the exposed skull, and the anteriolateral thigh perforator flap was transplanted afterwards. The descending branch of the lateral circumflex femoral artery and its accompanying vein of the flap were anastomosed with superficial temporal artery and vein or facial artery and vein before the suture of flap. The flap donor sites were covered by intermediate split-thickness skin graft collected from contralateral thigh or abdomen.@*Results@#The descending branch of the lateral circumflex femoral artery and its accompanying vein were anastomosed with superficial temporal artery and vein in six patients, while those with facial artery and vein in one patient. All the flaps survived after the operation, and no vascular crisis was observed. Wound healing was satisfactory. One patient was lost to follow up. Six patients were followed up for 6 to 10 months. The patients were bald in the head operation area with acceptable appearance. No psychiatric symptom such as headache or epileptic seizure was reported. The flap donor sites were normal in appearance. The muscle strength of the lower extremities all reached grade V. The sensation and movement of the lower extremities were normal.@*Conclusions@#Anterolateral thigh perforator flap with fascia lata transplantation can effectively repair electrical burn wounds of head with skull exposure and necrosis. The fascia lata can be used to protect the vascular pedicle of flaps, which is beneficial to the survival of the flap. Preoperative head and lower extremities CTA can provide reference for intraoperative vascular exploration in donor site and recipient area, so as to shorten operation time.

Objective To investigate reconstructive repair methods of a large scalp defect with the granulation tissue wounds and skull exposure caused by the trauma.Methods Skin and soft tissue expansion technique was used to repair eight patients with a large scalp defect with the granulation tissue wounds and skull exposure caused by the trauma.The skin and soft tissue expanders were embedded under normal epicranial aponeurosis after the formation of fresh granulation tissue wound.Strict aseptic technique as well as water injection was done in the expansion process and moderate expansion to maintain rich blood circulation in the expansive parts.Results 12 skin and soft tissue expanders were implanted in 8 patients and the scalp wounds were completely repaired.No infection was detected after surgery and injection expansion process.Conclusions The skin and soft tissue expansion can be used to reconstruct post-traumatic scalp defect with granulation tissue wound and skull exposure.
