Objective　To search a simple, safe and effective osteotomy for hypertrophied mandibular angle.Methods　Hypertrophied mandibular angles were classified as lateral bulge, posteroinferior projection and combination based on their appearances. With local nerve blocking and infiltrating anesthesia, 162 cases with hypertrophied mandibular angel were respectively operated by intraoral approach with sagittal split, curved or combinative osteotomy method according to their types. Hypertrophied masseters were partially resected simutaneouly in 75 cases combined with masseter hypertrophy, and buccal fat pads were extracted in 52 cases associated with round faces.Results　Postoperative follow-up of 3～12 months to 60 cases of them showed 94.3 % of them were satisfactory.Conclusion　This operative method is simple and safe.It has minimal influence on the overall body of patients, and it is accord with the rules of aesthetic surgery.

Objective To investigate the different procedure effects in patients with modified sub-pectoral and subglandular breast augmentation. Methods Patients with modified subpectoral breast aug-mentation (10 cases) and subglandular breast augmentation (10 cases) were randomly selected, and satis-factory surveys to the procedures were conducted in the two groups of patients, including breast touch-feeling, dynamic change, as well as self-feeling and spouse-feeling. Results By the comparison of sub-glandular with subpectoral breast augmentation, touch-feeling was excellent in the former group, with breast spreading out to bilateral side in horizontal position. The breasts had different changes with differ-ent posture and natural movement. Spouse was more satisfactory to the former than the latter group. Conclusion Subglandular breast augmentation has natural shape, dynamic changes and fidelity of the re-al, especially in horizontal position, which is more conformable to the standards of patients and their spouse, and better than subpectoral breast augmentation.

Objective To explore the treatment of capsular contr ac ture after augmentation mammaplasty with mammary prostheses. Method Through primary incision (axillary or inframammary) and minor capsu le incision, patients with capsular contracture after augmentation mammoplasty w ere treated by preserving the contractive capsule and repositing of the breast p rosthesis anterior to the primary capsule. Results Total ly 12 cases (14 breasts) of capsular contracture were achieved satisfactory res ults since 2001. Conclusion The method of capsule preser vation and reposting of the breast prosthesis anterior to the capsule present n umerous advantages: little trauma, less bleeding, simple surgical procedure, saf e, less possibility of recrudescence, and can be finished through a small primar y axillary incision. It is a preferable method to treat capsular contracture.

Objective To investigate clinical therapeutic effects after a series of improvements of multi-site combination in the simple obese patient with tumescent liposuction. Methods Before tumescence anesthetization, short-acting benzo-diazepine was used as sedative inducer. The pressure and fluid velocity of short-acting benzodiazepine were regulated and injected into deeper level of fat at first, and all of these actions decreased the pain of patients, and promote the effect of the pain tolerance. The positions of the incisions were selected to hide from view and specifically protected, which could improve looks and decrease the scar formation after operation. In later stage of operation the flaps were pressurized and slid from outside, in order to make the flaps even and smooth and to keep their thickness according to the position of the flaps and the age of the patients. Opened draining was changed to block draining after operation. Results 73 cases were taken the follow-up for 6～24 months. All cases obtained satisfactory results, except that one cases was complicated by scar hypertrophy. The changes of the circumferences were as follows: the decrease of the maximum circumference of thigh was from 2 cm to 17cm, abdomen from 3 cm to 24 cm, and buttocks from 1 cm to 3 cm. Conclusions A series of improvement of key measures enhance the clinical therapeutic effects of multi-site combination in the simple obese patient with tumescent liposuction.

Objective To explore the clinical value of autologous fat injection with platelet rich plasma in facial rejuvenation.Methods 35 female beauty seekers were collected in this study.They were divided into two groups:sample autologous fat group (FAT group,n=20) and combined autologous fat and platelet-rich plasma group (PRP group,n =15).The average level of injection was 34 ml.The fat was collected at the abdominal or thigh sites using 18 G needle connecting with negative pressure suction-pump.The fat was centrifugated 2 min to get rid of the lower layer of water and the upper layer of oil.Weigao PRP extract kit was used to obtain the PRP.The ratio of PRP to fat was 1:5.The injection technique was according to Colemen method.The survival rate,satisfaction and complication were compared between the 2 groups.Results There were no infection,hematoma,fat liquefaction necrosis occurred in the 2 groups.Compared with the FAT group,the skin texture and facial contour of the PRP group was improved.Conclusions The platelet rich plasma can improve the survival rate of fat and has a stable effect,which is one of the safe and ideal methods of facial rejuvenation.

ObjectiveTo avoid the complications such as scar,alopecie,scalp numbness,hematoma etc,resulted from the conventional coronal incision rhytidectomy,and to explore and solve the issues about endoscopic frontal and temporal rhytidectomy.MethodsThrough 3-5 short incisions in hairline,we dissected under frontal periosteum or gales aponeurotica and in superficial layer of deep temporal fascia.The frontal and temporal cavitites were feedthrough at temporal crest.The corrugator supercilii muscle,superciliary depressor muscle,frontal muscle and orbicularis oculi were treated.Sufficient dissection was done under the periosteum of os orbitale.ResultsThis method had been applied in 186 patients with forehead lift.After operation,transient paralysis of facial nerve frontal branch were found in 3 patients.The depression of glabellum and lateral canthus were found in 5 patients.The depressions were corrected by autologous fat injection. Other 178 patients' results were satisfactory.ConclusionsEndoscopic frontal and temporal rhytidectomy has some advantages,such as minute invasion,less hemorrhage,few complications,and stable operation result,etc.Compared to the conventional coronal incision rhytidectomy,this method will be used more widely.

Objective To evaluate the results of prosthesis augmentation,relieve suffering patient experience,improve shape and touch of breast.Methods According to design,in dual-plane mammaplasty transaxillary approach with endoscopic assistance,we used soft-tissue expansion before prosthesis,saline volume in expander was the same as prosthesis size at beginning; adjusting expander volume and position,then determined prosthesis size according to expander volume lastly.after intraoperative sustained expansion for 30 to 60 minutes twice prosthes volume,replace expander with prosthesis.Results This method was applied in 120 patients,showing that pain significantly reduced after expansive without use of analgesia pump; complications included that 3 patients appeared seroma and absorbed soon; 2 patients had poor prosthese location,which was adjusted in reoperation; one capsular contracture was repaired later.After 6-months to 2-years follow-up,the results showed that breast was nature and dynamic; satisfactory rate reached to 95 ％.Conclusions In augmentation mammaplastic operation,pre-adoption of an expander can make it easy to adjust the location of prosthesis,to avoid being injured and to determine prosthesis volume by expander injection of saline volume,especially for patient with different size of both breasts.

Objective To study the technology and the result of dual plane breast augmentation using nipple margin vertical incision of areola.Methods Totally 60 cases of augmentation mammaplasty were involved in this study.The nipple margin vertical incision of areola was applied obliquely into the breast through the pectoralis major fascia.The rib starting point of pectoralis major were cut off,medial to the side of the sternum.Under the pectoralis major the cavity was peeled according to the preoperative design range.Based on the different situation of the breast types Ⅰ,Ⅱ,Ⅲ,dual plane breast augmentations were stripped respectively.After implanting the breast prosthesis,the upper part of the prosthesis was under the pectoralis major and the lower part was under the mammary gland.Results The 60 patients were all after childbearing,20 of whom underwent type 2 dual plane breast augmentation,4 underwent type 3 double plane and the rest underwent type 1 double plane.After 3 months to 2 years follow-up,all cases got satisfactory results,except 1 case of postoperative hematoma and 1 case appeared capsular contracture.Conclusions The nipple margin vertical incision of areola can complete types Ⅰ,Ⅱ,Ⅲ dual plane breast augmentation operation,at the same time it can correct mild-to-moderate mastoptosis.

Objective To explore a more efficient surgical method to cure axillary osmidrosis through a comparative study on results from two surgical treatments of axillary osmidrosis in the armpit area.Methods 72 patients were randomized into two groups,in which 36 patients (group A) with micro-incision simple liposuction and 36 patients (group B) with dissection and excision of subcutaneous tissue from axillary folds.The clinical outcomes in the two groups were comparatively analyzed,based on surgery time,effect,complications,scarring and recovery time.Results The total efficiency of axillary osmidrosis treatment was 100％ after 6-12 months clinical follow-up towards two groups.There was no significantly statistical difference on the effect of both groups.Micro-incision simple liposuction was obviously superior to dissection and excision of subcutaneous tissue from axillary folds based on surgery time,complications,recovery time,scarring and armpit hair survival rate.The two groups were significantly different (P＜0.05).Conclusions Minimally invasive simple liposuction,as a treatment for axillary osmidrosis is a method with more effectiveness and reliability.It is a more acceptable approach to patients in view of safety and convenience,smaller and invisible scarring,fewer complications,and less recovery time.

Objective To investigate the techniques and signifcations of endoscopic forehead lift when it was done alone or in combination with conventional facelifting.Methods For the patients with forehead transverse wrinkle,vertical frown line and eyebrow ptosis,resection of partial frontalis muscle,procerus muscle and eorrugator muscle was performed.If the patients had obvious excessive and drooping skin in middle face and lower face together with the wrinkles that were mentioned above,endoscopic forehead lift in combination with conventional facelifting was done at the mean time.The excessive skin was tailored and removed,SMAS was complicated or resected and sutured.Results 104 patients were subjected to the endoscopic forehead lift,in which 20 cases underwent it alone,and another 84 cases were treated in combination with the conventional facelifting.Of all cases,104 patients presented satisfactory results of forehead.They showed the eliminating of transverse wrinkle of forehead,glabellas vertical fold and lifting of eyebrow ptosis.Complications were less and minimal,including minimal local depression,retrodisplacement of hairline of forehead,recurrence of wrinkle and numb of forehead.No injuring of temporal branch of facial nerve occurred in this group.The cases that underwent endoscopic forehead lift in combination with conventional faeelift showed the coordinate and consistence of rejuvenation from forehead to middle face and lower face.Conclusions Endoscopic forehead lift is a minimally invasive technique,and it presents more satisfactory results with less severe complications.Its operative principle is reasonable,procedure is safe and reliable,and therefore it represents the tendency of developing of plastic surgery and cosmetic surgery.If patients have obvious excessive and drooping skin in middle face and lower face,endoscopic forehead lift is suggested in combination with the conventional facelift,and this resolution shows more balanced and coordinate cosmetic correction of whole face.
