Objective To explore a novel strategy to repair traumatic soft tissue defects in the head and face by tissue expansion in the early stage.Methods Eighteen patients with traumatic soft tissue defects were treated with thorough debridement leaving the wound unclosed or simply closed with thin split-thickness scalp skin grafting,and adjacent expander implantation in the early stage and expanded flap transposition in the second stage.Results There were 11 male patients and 7 female patients ranging in age from 3.5 to 40 years [mean,(19.4±12.2) years],with average 15 months follow-up (range,3-67 months).The average expansion time was 74.3 days (range,53-96 days).The total of 18 patients with 22 expanders were treated with satisfactory results.All the flaps survived and the skin color,texture and contour well matched to those of the peripheral tissue.Only one complication of infection happened in the 18 cases (5.56%) and total 22 expanders (4.55%),which was similar to the rate reported in the literature.There were no any other complications related to the expander.Conclusions Debridement and tissue expansion in the early stage have been proved a more effective strategy to repair traumatic soft tissue defects in the head and face,which can not only achieve satisfactory color,unbulky and well matched texture similar to normal,but also can avoid unnecessary donor site injuries and does not increase the infection rate of tissue expansion.

Objective To investigate the possibility of performing epicanthoplasty with same stage small incision blepharoplasty. Methods At the same stage of designing small incision blepharo-plasty, modified "Z" plasty without flap transposition was designed. The upper lid incisive line of epi-canthoplasty was bided in the double eyelid fold, while the lower eyelid incision located at the edge of eyelid. Results A series of 56 patients were treated with this method. Satisfactory esthctical result of double eyelid fold and inner canthus shape was achieved. Conclusion This modified method including epicanthoplasty combined with same stage small incision blepharoplasty has the advantages of minimal scar formation, easy to design perform and in accordance with physiology.

Chinese Journal of Plastic Surgery 2019;35(9):934-937
The lateral canthus is the junction of the upper and lower eyelids, which is located at the temporal side. The distance from the lateral orbit rim to the lateral canthal angle is 5-7 mm. Cosmetic lateral canthoplasty, as an important surgical method for the rejuvenation of the eyes, was developed in recent year. Along with the development of anatomic study of the lateral canthus, the cosmetic lateral canthoplasty was modified and improved. The purpose of this review is to summarize the anatomy of the lateral canthus, indications for cosmetic lateral canthoplasty and surgical procedures, so as to provide a useful reference for clinicians.

Objective To discuss the clinical application of using trimmed latissimus dorsi free muscle flap together with skin grafting to resurface soft tissue defects on the dorsum of the foot. Methods From June 2005 to October 2011,eleven patients (8 males and 3 females,aged from 4-46 years) with large soft tissue defects of the foot dorsum were treated in our department. The size of the defects after debridement ranged from 5.0 cm × 6.0 cm-8.0 cm × 12.0 cm,all with exposed tendons or bones.Trimmed free latissimus dorsi muscular flap with split thickness skin grafting was used for reconstruction for all the 11 patients. Results All the flaps survived with no complications after surgery.During 3-10 months' follow-up,the appearance and walking function were satisfying, no further debulking procedures were needed. Conclusion Trimmed latissimus dorsi free flap with skin grafting is a good option for dorsal defect reconstruction.

Objective To explore the technique of massive facial scar revision. Methods All 12 patients in the group were treated with expanded deltopectoral skin flap. In the primary surgery, expander was implanted underneath deltopectoral flap region through an incision inferior to the clavi-cle. The skin perforators of transverse cervical artery and thoracoacromial artery were ligated during surgery, and the internal thoracic artery was carefully preserved. After the deltopectoral skin flap was fully expanded, the second surgery was performed and the facial scar was released and the normal ana-tomic position of eyes, nose and month was restored. The deltopectoral skin flap was planed according to the size of the defect. The excised facial scar was converted to the flap pedicle and a hinge-like con-nection was formed. The flap was delayed and three weeks after the second surgery, the pedicle was divided. The flap from the pedicle was applied for the mental region scar revision. Results Unilateral or bilateral dehopectoral skin flaps were employed for the repair of extensive facial scar in 12 patients. Satisfactory results were achieved in all these patients. Conclusion Expanded deltopectoral skin flap is a good technique for the repair of extensive facial scar.

With the technology development of cancer treatment, the survival rate of patients with cancer has been significantly improved. However, chemotherapy and radiation therapy may lead to premature ovarian failure and infertility in young women with cancer. Cryopreserved ovarian tissue auto-transplantation is an effective method to preserve fertility of such female patients. At present, the biggest challenge of this technique is mass loss of follicles after transplantation. In this article, the influencing factors and improvement methods of survival of cryopreserved ovarian tissue auto-transplantation were reviewed.

Objective To review the clinical features of the patients received massive transfusion (MT) in plastic surgery department.Methods Ten cases were reviewed.The reason of massive transfusion,the type and dosage of transfusion,the reaction of patients were included.For all the patients,consultation of related department preoperatively was necessary.Based on the through and detailed analysis of the patients' condition,necessary blood product should be prepared ahead of operation.During the therapy,adjustment of treatment plan was made from time to time,according to the patient's condition.Therefore efficient and prompt therapeutic result was achieved.Results In all the 10 MT cases suffered from acute blood loss,2 of them were in hemorrhagic shock before administration.Coagulation disorders happened in 2 patients,and recovered after appropriate treatment.RBC,which was 58.3% of total amount of transfusion,used most commonly;the second was fresh frozen plasma (FFP),which was 38.6% according to the total amount.All the patients had satisfactory recovery,without hemolysis or any other functional disorder.Conclusions For MT patients in the Department of Plastic Surgery,the main proposes are to restore and maintain an effective circulatory blood volume,while preventing the coagulation disorder.Also,detailed analysis,through consultation and timely adjustment are of great importance for the MT patients.It is also the essential of an effective perioperative management.

Objective:
To investigate the feasibility of one-stage thinning of latissimus dorsi muscle, rectus abdominis muscle and gracilis flap in reconstruction of the hand and foot defects.
Methods:
From June 2009 to April 2015, 24 free muscle flaps were thinned during transfer operation by removing their superficial muscle layers on the basis of their vessel pedicles running in the deep surface of flaps. The surface of the muscle flaps were covered by split-thickness skin grafts. There were 16 latissimus dorsi muscle flaps, 4 gracilis flaps and 4 rectus abdominis muscle flaps. Flap size ranged from 6 cm×4 cm to 20 cm×12 cm. Thinned muscle flaps were used to resurface 7 hand defects and 17 foot defects.
Results:
All muscle flaps survived the thinning procedures without any circulation problems except for one case which suffered total flap necrosis due to venous thrombosis. Skins grafts on muscle flaps also took well. One patient experienced partial skin loss. Two patients underwent secondary debridement and thinning procedure for infection and bulkiness. During the 0.3-20 months follow-up, the contour of thinned muscle flaps matched well with the recipient areas. Reconstructed feet are able to wear regular shoes.
Conclusions
Intraoperative immediate thinning of free muscle flaps can be safely accomplished during the primary reconstruction procedure. This procedure prevents the limitations of muscle flap bulkiness and may provide an alternative for surface coverage.
