The reconstruction of the suborbital area followed by resection of skin cancer has been used many methods including skin graft, local flaps, free flaps, and skin expansion. The radial forearm free flap has become a workhorse flap in this area because of its lack of bulk, ease of dissection, malleability, and hairlessness. When the suborbital defect especially including full-thickness defect of lower lid was reconstructed with many free flaps, the ectropion and the deformity of medial and lateral canthal area were common problems encountered as late complication due to gravitational descent. To improve the final aesthetic result in patients with suborbital defect, the radial forearm free flap was elevated as a composite radial forearm - palmaris longus free flap, in which the vascularized palmaris longus london was included and anchored to the periorbital bone with $mitek^{(R)}$ as sling, to suspend the flap against gravity and inferior descent, and thereby creating a more natural cheek contour. Two clinical cases were presented as an example of this procedure. Postoperative results emphasize the importance of suspension sling with palmaris longus tendon using $mitek^{(R)}$ in reconstruction of the suborbital defect with radial forearm free flap.

Purpose: Mucinous eccrine carcinoma of the skin is rare skin adnexal malignant tumor, which most commonly occurs in the head and neck regions. This tumor, although rarely metastatic, has a high incidence of local recurrence. We report a case of mucinous eccrine carcinoma developed on the Lt. cheek which was treated by Mohs surgery. Methods: The patient was a 53-year-old man who showed a palpable skin-colored $1.5{\times}1.5cm$ sized mass on Lt. cheek. We treated it by wide excision, but it recurred several times on the same region. So we finally did the Mohs surgery and full thickness skin graft. Results: The histologic characteristics are large mucinous pools with fibrous septae and clusters of tumor cells. Special stains showed that the mucin was positive reactivity on Periodic acid Schiff. Also the immunocytochemical studies showed a positive reactivity to carcinoembryonic antigen, S-100 protein, cytokeratin-7. Therefore pathologist reported it as a mucinous eccrine carcinoma. Conclusion: Authors experienced a rare case of primary mucinous eccrine carcinoma on Lt. cheek which had recurred several times. Because of the high local recurrence rate, we did the Mohs surgery and got an good result. Therefore the early Mohs surgery would be a good choice to primary mucinous eccrine carcinoma.

Purpose: Traditional radical surgery for vulvar cancer produces severe skin and soft tissue defects in the vulvar and vaginal area. Vulvoperineal V-Y advancement fasciocutaneous flaps have limitations in advancement and tension at the wound margin and vaginal orifice area, causing wound disruption or vaginal wall exposure. Therefore, we designed the "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap for 3-dimensional reconstruction of vagina and vulvar area. Methods: A 27 year-old female was diagnosed with vulvar intraepithelial neoplasia. Radical vulvectomy and full-thickness-skin-graft was performed. We designed a vulvoperineal V-Y advancement fasciocutaneous flap as the greater wing and inguinal rotational skin as the lesser wing. After flap elevation, the inguinal flap was rotated $180^{\circ}$ to reconstruct the labia major and vaginal orifice. The perineum was reconstructed using V-Y advancement flaps. Results: The flap survived completely, without any complications. After 6 months, the patient was able to perform normal sexual activities and after 18 months, the patient was able to give birth to normal child by caesarean section. Conclusion: The traditional vulvoperineal V-Y advancement fasciocutaneous flap is thin, reliable, easily elevated and matches local skin quality. However, the vaginal wall becomes exposed due to limited advancement and tension of the flap. The "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap is useful for the release of vaginal orifice contracture, reconstruction of the labia major, and 3-dimensional reconstruction of vagina and vulvar area.

Soft tissue reconstruction of dorsum of the foot and ankle has long presented challenging problems for the reconstructive surgeon. Limitations of available local tissue, the need for specialized tissue, and donor site morbidity restrict the options. In an effort to solve these difficult problems, we have begun to use adipofascial flap based on the perforating branch of the peroneal artery. We present our early experience of 5 patients treated with this flap. Our patients ranged from 6 to 26 years in age and included 3 males and 2 females. The etiologies of the wounds were secondary to traffic accident, and crushing injury. The flaps had reverse flow in all patients. The flap and the adjoining raw area were covered with a full-thickness skin graft, while the donor site at the lateral aspect of the leg was closed primarily without grafting. The skin graft was taken from the inguinal area, which was closed primarily. Compared with other flap, this adipofascial flap is thinner, producing less bulkiness to the recipient site and minor aesthetic sequelae to the donor site. In our opinion, this flap is versatile, effective, and an addition to the armamentarium of the reconstructive surgeon for coverage of difficult wounds of the foot and ankle.

Background Nipple-areolar complex (NAC) reconstruction is the final stage of breast reconstruction. Ideal reconstruction of the NAC requires symmetry in position, size, shape, texture, pigmentation, and permanent projection, and although many technical descriptions of NAC reconstruction exist in the medical literature, there is no gold standard technique. The technique devised by the authors is very versatile, with excellent results, and it enables 1-step reconstruction with optimal results in terms of shape and nipple projection. Methods Our technique consists of a combination of modified local flaps and a full-thickness skin graft. Patients were observed for 18 months to estimate the amount of retraction. This procedure was performed in 40 patients, four of them bilaterally. The duration of the follow-up was 30 months. Complications occurred in 10% of patients, and included infections (5%), ischemia (2.5%), and hematoma (2.5%). Results No cases of total nipple necrosis were reported. The NAC shape remained optimal in all cases, with a very small reduction of the vertical and horizontal diameters of the areola, which maintained its designed round shape well, and negligible retraction in the diameter and projection of the nipple. Conclusions The oval technique represents a major step forward, involving a combination of existing techniques, such as the C-V flap and the cutaneous graft, to achieve excellent results regarding areola shape and nipple projection, significantly reducing the cases of nipple ischemia. These results were substantially obtained through subcutaneous equatorial sutures, skin grafting, and flattening of the apexes of the flap.

Background: Microstomia is defined as a condition with a small sized-mouth that results in functional impairment such as difficulty with food intake, pronunciation, and poor oral hygiene and cosmetic problems. Several treatment methods for microstomia have been proposed. None of them are universally applicable. This study aims at analyzing the cases treated at our institution critically reviewing the pertinent literature. Methods: The medical records of all microstomia patients treated in our hospital from November 2015 to April 2018 were reviewed retrospectively. Of these, all patients who received surgical treatment for microstomia were included in the study and analyzed for etiology, chief complaint, surgical method, and outcomes. The functional outcomes of mouth opening and intercommissure distance before and after the surgery were evaluated. The cosmetic results were assessed according to the patients' satisfaction. Results: Five patients with microstomia were corrected. Two cases were due to scar contracture after chemical burn, two cases derived from repeated excision of skin cancer, and one patient suffered sequela of Stevens-Johnson syndrome. The following surgical methods were applied: one full-thickness skin graft on the buccal mucosa, three buccal mucosal advancement flaps after triangular excision of the mouth corner, and one local buccal mucosal flap. Mouth opening was increased by 6.0 mm, and the intercommissure distance improved by 7.2 mm on average. Follow-up was 9.6 months (range, 5-14 months). Cosmetic assessment was as follows: two patients found the results excellent, three judged it as good. Conclusion: Microstomia has several causes. In order to achieve optimal functional recovery and aesthetic improvement it is important to precisely evaluate the etiologic factors and the severity of the impairment and to carefully choose the appropriate surgical method.
