OBJECTIVE:
To review the advances in methods for reconstructing nipple projection based on tissue graft support.
METHODS:
The literature related to nipple projection reconstruction based on tissue graft support was reviewed and summarized in terms of the advantages and disadvantages of various tissue grafts and the improved nipple projection results.
RESULTS:
Loss of nipple projection is a common cause of decreased patient's satisfaction. Reconstructing nipple projection based on tissue graft support is a more common clinical method and can be done with autologous and allogeneic tissues. Autologous tissue grafts include dermis, adipose tissue with dermis, adipose tissue, ear cartilage, rib cartilage, and contralateral nipple tissue. Autologous tissue grafts are easy to obtain and have no immune rejection, but may lead to donor area damage and prolong the surgical time for tissue collection. Allogeneic tissue grafts include acellular dermal matrix, lyophilized rib cartilage, and extracellular matrix collagen, and decellularized nipple tissue. Allogeneic tissue grafts do not cause additional donor area damage, are highly malleable, and can be designed to be utilized according to the recipient area, but the high cost often limits the development of this technique.
CONCLUSION
There is no gold standard regarding tissue graft-assisted nipple projection reconstruction techniques, and there are advantages and disadvantages to both autologous and allogeneic tissue grafts. Surgeons should choose the appropriate graft based on the actual condition of the patient.

2.Augmentation of quality of wound healing of deep burn.
Chinese Journal of Burns 2009;25(1):3-5
This article summarizes methods of repair of massive and deep wounds, elucidates how to improve wound healing quality and avoid scar deformity after deep burn. A part of denatured dermis (non-necrotic) in deep partial-thickness burn, "mixed degree" burn, even in full-thickness burn wounds before forming eschar can be preserved and covered with autologous skin, thereby to avoid secondary damage to the structure of subcutaneous tissue and the junction of dermis-adipose, thus to result in good functions, appearance, and survival rate. After skin grafting, wound healing quality and appearance are improved, joint function and elasticity of skin are enhanced, the degree of scar contracture is relieved due to preservation of normal adipose tissue after escharectomy. The study of composite artificial skin will be actively developed in the future. Tissue-engineering skin and stem cells can be successfully used in patients with deep burns for scarless healing with restoration of physiological functions in a short period.

Autologous fat injection had not gained an attention in aesthetic plastic surgery, because of high reabsorption. Recently, fatty tissue was obtained by the low-power technique and centrifuged, results of autologous fat injection was improved. The authors performed autologous microfat injections on 277 patients from March 1997 through December 2002 to correct soft tissue facial contour such as aging, depressed facial contour, thin and long faces as well as postoperative complications and scars. The fatty tissues remaining from the first injection were kept at -20 degrees C up to twelve months, and were used for repeated injections in the overly- absorbed or inadequate areas. Of those 277 patients, 59% received an injection once, 35% received an injection twice, 5% received an injection three times and 1% received an injection up to four times. Follow-ups and postoperative photo confirmations were possible only in 119 out of 277 cases. 81.5% showed satisfied results, and development of complications were insignificant occurring at 6.2%. Owing to advances in tissue engineering and frozen storage method, autologous microfat used for injection will be developed as a better filler, which may substitute soft tissues.

OBJECTIVETo introduce the experience in the treatment of lower eyelid pouches orbital rim.
METHODSAn incision was made along the margin of lower eyelid and dissection was performed under the orbicularis muscle to expose the orbital septum and periosteum of lower orbital rim. The fat released from orbital septum was transposed just below the lower orbital rim and fixed on the periosteum. If lacrimal groove deformity was not corrected completely, the musculocutaneous flap, which may be excised beside the incision, was kept to correct the deformities further with only the muscle portion.
RESULTS72 cases with lower eyelid pouches complicated with lacrimal groove deformities were treated with transposition of orbital fat and orbicularis muscular flaps. Satisfactory results were achieved in all the patients after a follow-up period of 3-6 months.
CONCLUSIONIt is an effective and feasible technique to correct lacrimal groove deformities with transposition of orbital fat and orbicularis muscular flaps.

Knee osteoarthritis (KOA) is the most common knee joint disease. Although KOA belongs to a disease of degeneration of knee joint cartilage, its pathology involves cartilage, subchondral bone, meniscus, synovial membrane, articular capsule and other joint tissue. The infrapatellar fat pad (IPFP), an intracapsular but extrasynovial structure, has some special characteristics of endocrine metabolism, then it has double roles in the development of KOA, but its protective effect is much more than harmful effect. Considering protective roles of IPFP in KOA and some serious complications after IPFP resection, the surgeon shall protect IPFP as far as possible if total knee arthroplasty surgical field is good. If it is necessary to improve the surgical field, its fibrotic tissue even all part can be removed.

Objective:
To investigate the application of suprapubic lipectomy with a "Ω" incision to removal of the prepubic fat pad for the management of buried penis in obese adult patients.
METHODS:
We retrospectively analyzed the clinical data on 20 obese adult patients with buried penis treated by suprapubic lipectomy via a "Ω" incision between August 2016 and September 2019.
RESULTS:
The operations were successfully completed in all the cases, with a mean operation time of 3.7 ± 0.6 hours and an average hospital stay of 8.3 ± 3.3 days. There were no such severe surgery-related complications as hematoma, urethral injury, or fat embolism in any of the cases. Fat liquefaction-related superficial wound infection developed in 1 patient postoperatively, which was cured by combined topical and systemic antibiotic therapy. A 3-month follow-up showed a 95% satisfaction of the patients with the postoperative appearance of the penis and suprapubic incision, but no complications such as ED, abnormal penile sensation, or penile retraction.
CONCLUSIONS
Suprapubic lipectomy with a "Ω" incision to remove the prepubic fat pad is an effective surgical approach to the management of buried penis in obese adult males, which is an anatomy-based surgical correction and has the advantages of slight injury, rapid recovery and few complications./.

OBJECTIVE:
To investigate effectiveness of transconjunctival lower eyelid blepharoplasty with "super released" orbital fat in correction of lower eyelid pouch protrusion and tear trough and palpebromalar groove depression.
METHODS:
A clinical data of 82 patients (164 sides) with lower eyelid pouch protrusion and tear trough and palpebromalar groove depression, who met the selection criteria between September 2021 and May 2022, was retrospectively analyzed. Of the included patients, 3 were males and 79 were females, with an average age of 34.5 years (range, 22-46 years). All patients had varying degrees of eyelid pouch protrusion and tear trough and palpebromalar groove depression. The deformities were graded by the Barton grading system as gradeⅠ in 64 sides, grade Ⅱ in 72 sides, and grade Ⅲ in 28 sides. The orbital fat transpositions were performed through the lower eyelid conjunctival approach. The membrane surrounding the orbital fat was completely released, allowing the orbital fat to fully herniate until the herniated orbital fat did not retract significantly in a resting and relaxed state, which is regarded as the "super released" standard. The released fat strip was spread into the anterior zygomatic space and the anterior maxillary space, and percutaneous fixed to the middle face. The suture that penetrates the skin was externally fixed by adhesive tape pasting without knotted.
RESULTS:
There were 3 sides with chemosis after operation, 1 side with facial skin numbness, 1 side with mild lower eyelid retraction at the early stage after operation, and 5 sides with slight pouch residue. No hematoma, infection, or diplopia occurred. All patients were followed up 4-8 months, with an average of 6.2 months. The eyelid pouch protrusion, tear trough, and palpebromalar groove depression were significantly corrected. At last follow-up, the deformity was graded by Barton grading system as grade 0 in 158 sides and grade Ⅰ in 6 sides, with a significant difference compared to the preoperative score ( P<0.001). Patient's self-evaluation satisfaction reached very satisfied in 67 cases (81.7%), satisfied in 10 cases (12.2%), generally satisfied in 4 cases (4.8%), and dissatisfied in 1 case (1.2%).
CONCLUSION
The "super released" orbital fat can effectively prevent the retraction of orbital fat, reduce the probability of residual or recurrence of eyelid pouches, and improve the correction effect.

OBJECTIVE:
To explore the effectiveness of hairpin shaped incision combined with cover-lifting flap in plastic surgery of huge fat pad on nape and back.
METHODS:
Between March 2019 and March 2023, 10 patients with huge fat pad on the nape and back were treated. There was 1 male and 9 females with an average age of 52 years (range, 39-57 years). All patients had soft tissue bulge on the nape and back. Preoperative MRI showed the subcutaneous fat thickening. The length of the longitudinal axis of the fat pad ranged from 10.0 to 25.0 cm (mean, 14.1 cm), the length of the transverse axis ranged from 6.0 to 15.0 cm (mean, 10.8 cm); the thickness of the fat pad ranged from 2.5 to 5.1 cm (mean, 3.9 cm). Under general anesthesia, the patient was placed in a prone position and a hairpin shaped incision was made. The flap was lifted to remove the fat pad according to the marked area. The dressing was changed every 2 days after operation.
RESULTS:
The operation time was 35-110 minutes (mean, 72 minutes). The intraoperative blood loss was 35-80 mL (mean, 49.5 mL). The drainage tube was removed at 2-5 days after operation (mean, 3.4 days). All incisions healed by first intention without incision dehiscence, infection, subcutaneous bruising, hematoma, or other related complications. All patients were followed up 2-24 months (mean, 12 months). All patients had a good shape of the nape and back and no noticeable scar on the incision. According to the Vancouver Scar Scale evaluation criteria, the incision scar score was 3-5 (mean, 3.7) at 2 months after operation. Patients had good neck movement with no recurrence.
CONCLUSION
For the huge fat pad on the nape and back, the plastic surgery using hairpin shaped incision and cover-lifting flap has the advantages of fully exposing the fat pad, concealed incision, simple operation, and natural shape of the nape and back after operation.

BACKGROUND: Soft tissue defects of the posterior heel of the foot present difficult reconstructive problems. This paper reports the authors' early experience of five patients treated with a lateral calcaneal artery adipofascial flap. METHODS: Between 2003 and 2007, five patients (3 males and 2 females) with soft-tissue defects over the posterior heel underwent a reconstruction using a lateral calcaneal artery adipofascial flap and a full-thickness skin graft. The flap sizes ranged from 3.5 x 2.5 cm to 5.5 x 4.0 cm. RESULTS: All five flaps survived completely with no subsequent breakdown of the grafted skin, even after regularly wearing normal shoes. The adipofascial flap donor sites were closed primarily in all patients. CONCLUSIONS: Lateral calcaneal artery adipofascial flaps should be included in the surgical armamentarium to cover difficult wounds of the posterior heel of the foot. These flaps do not require the sacrifice of a major artery to the leg or foot, they are relatively thin with minimal morbidity at the donor site, and leave a simple linear scar over the lateral aspect of the foot.
