Objective:
To summarize the individual design of the perforator flap based on the descending branch of the lateral circumflex femoral artery and ecological protection of the flap.
Methods:
From June 2013 to June 2017, 33 cases of extremities wound defects were repaired with the descending branch perforator flap of the lateral circumflex femoral artery. According to the chracteristics of extremity wound and the anatomy of the descending branch perforator of the lateral circum flex artery, a medial incision of the flap according to the demarcation line was performed. Through meticulous dissection, two perforator branches were found and traced on the surface of facia lata. The size of the kiss flap was adjusted according to the perforator caliber. The chimeric muscular flap was incised according to muscular penetration point of the perforator and the course of lateral fermoral nerve with cautious protection of muscular branch of femoral nerve. During the incision, fascia lata, nerves and muscles on donor site were protected to reduce the damage to donor site. Meanwhile, ecological structure on donor site was reconstructed. Our series include 22 males, 11 females. The average age ranged from 13 to 71 years (mean: 47years). There were 21 cases of wounds on dorsum manus and wrists and 12 cases of wounds on the dorsum pedis and lower limbs. The wound dimension ranged from 7 cm×8 cm to 13 cm×24 cm. The flap dimension ranged from 6 cm×7 cm to 8 cm×15 cm.There were 22 cases of KISS flaps and 11 cases of chimeric flaps. Wounds on all donor sites were primarily sutured. Course of the disease ranged from 1 week to 2 months.
Results:
All flaps were harvested uneventfully and survived well. No vascular crisis occurred. Wounds on all donor sites were primarily sutured. Three to 24 (mean 18) months of follow-up was made on 28 cases. The color and texture of flaps was good. Appearance of the flaps was good. Protective sensation recovered. Only linear scar can be seen on donor sites. No muscular hernia and cinesipathy was noticed on donor sites.
Conclusions
The size of KISS flaps depends on the caliber of perforator branch estimated intraoperatively. Muscular part of the chimeric flaps was harvested according to the muscular entry points of perforators and the demand of recipient sites. The wound defects were reconstructed individually according to the peculiarity of the defects. Fascialate, nervus cutaneus and muscle was cautiously protected in the course of flap harvest. Ecological structure was reestablished after flap harvest to reduce complications.

Objective:
To evaluate the clinical effect of the modified nasolabial flap with facial subcutaneous pedicle advanced flap in repairing the defects after midcheek tumor resection.
Methods:
From June 2012 to June 2017, 27 patients with facial tumors were treated, and according to the nature of the tumor, the tumor tissue was enlarged, frozen pathological examination was performed during the surgery. Once the edge and the base were reported to be negative, the nasolabial flap with facial subcutaneous pedicle advanced flap with a maximum 1 cm wider than the defect width was designed according to the position and size of the wound. The proximal border of the flap was designed at the cured edge of the circular wound. The curved bottom edge of the circular wound was the proximal end of the flap. The defects ranged from 2.0 cm×3.0 cm to 2.5 cm×4.0 cm. The donor site was directly sutured after subcutaneously loosening.
Results:
The operation was smooth, and the flaps were about 3.0 cm×6.0 cm to 3.5 cm×7.0 cm. The flaps were well transported after surgery, and there was no bruising at the tip. The suture was removed 1 week after surgery. After 6-36 months of follow-up, postoperative scar was not obvious, which were most hidden in the nasolabial folds. There was no ectropion and mouth deformity. The flaps were not swollen, and the color and texture were close to that of normal skin. The appearance was satisfactory. Sensation of skin were well recovered.
Conclusions
The modified nasolabial flap with facial subcutaneous pedicle advanced flap is suitable for repairing the facial defects with satisfactory skin sensation and good appearance.

Objective:
To explore the effect of the perforator flap of the proper digital artery on the ulnar or radial side of the finger in the treatment of webbed scar contracture of the same finger in child.
Methods:
From January 2012 to January 2016, 26 children who were treated with dressing change after burn of finger and then had webbed scar contracture along with growth and development were hospitalized in our unit, involving a total of 50 fingers. There were 14 males and 12 females among the children aged from 2 to 14 years. After the scar was dissected and released, the wound area ranged from 1.6 cm×1.0 cm to 5.0 cm×2.6 cm. The perforator flap of the proper digital artery of the ulnar or radial side of the same finger was used to repair the wound. The flap area ranged from 1.8 cm×1.0 cm to 4.6 cm×1.8 cm. The donor sites were sutured directly. The residual wounds in donor and recipient sites were repaired by full-thickness skin graft collected from inguinal area/adjacent area or adjacent perforator flap. The postoperative development and function of the fingers were followed up and observed. The range of motion of the fingers was evaluated according to the Chinese Medical Association Hand Surgery Society′s upper limb functional evaluation trial standard, the Kantor Scar Cosmesis Assessment and Rating Scale was used to score the scar of finger, and the latest data were recorded.
Results:
The flaps and skin grafts survived successfully after operation. The patients were followed up for 6 to 24 months. The perforator flaps of the proper digital artery on the ulnar or radial side of the finger survived well at the latest follow-up, with good color and texture and a two-point discrimination distance of 9 to 12 mm. There was no contracture of the fingers, a little pigmentation in the skin graft area, no flexion deformity of the fingers, no lateral bending of the fingers to the flap-harvesting side, and no scar contracture at the webs of the fingers. Compared with that of healthy side, the development of finger was not obviously abnormal. The range of motion of the fingers was excellent in 38 fingers and good in 12 fingers, and the scar score of the fingers was 2-3 points in 31 fingers, 4-7 points in 15 fingers, and 8-10 points in 4 fingers.
Conclusions
The efficacy of perforator flap of the proper digital artery of the ulnar or radial side of finger in the treatment of the webbed scar contracture of the same finger in child is reliable, with high postoperative survival rate of the flap, better color and texture, and fewer complications, which can avoid the risk of re-contracture of the finger in a short period after operation, and does not affect the growth and development of the finger.

Objective:To explore the effect of high-flow airway humidification on aspiration and residues in cases of dysphagia after a tracheotomy.Methods:Seventeen persons with dysphagia after a tracheotomy were asked to swallow 5ml of a thick liquid when their tracheal cannula was either connected to a high-flow airway humidification system or blocked, or the cuff was empty or full. Endoscopic evaluation was then used to grade the residue and aspiration in the different conditions.Results:There were significant differences in the residuals grading and aspiration among the four conditions. The average penetration-aspiration scale grade was significantly lower when the subject was connected to high-flow airway humidification than in the other three conditions. The grade of residuals was also significantly lower.Conclusion:High-flow airway humidification can effectively improve the swallowing of persons with dysphagia after a tracheotomy.

Objective:To explore the value of flexible endoscopic evaluation of swallowing (FEES) in guiding the decannulation of neurological disease patients with dysphagia after a tracheotomy.Methods:The FEES results of 188 neurological disease patients with dysphagia who had undergone a tracheotomy were analyzed retrospectively. The utility of FEES evaluation indexes (including glottis activity, the classification of pharyngeal secretions and residues as well as penetration-aspiration grade) for predicting the success of decannulation was explored.Results:One hundred and nine of the patients (the success group) were decannulated successfully and 79 (the failure group) were not, a success rate of 57%. The abnormal glottis activity rate among the failure group was 55%, significantly higher than among the success group (21%). The pharyngeal secretion classifications and penetration-aspiration grades among the success group were also significantly lower than among the failure group, on average. The average course of recovery from the tracheotomy was 184 days in the success group, significantly shorter than that of the failure group (292 days). No significant differences in residues were observed.Conclusion:The glottis activity, secretions and intake aspiration evaluated using FEES are of great value for guiding the decannulation of neurological disease patients with dysphagia after a tracheotomy.
