The soft tissue triangle is an easily recognizable subunit of the nose. Therefore, deformities in this region resulting from trauma or complications after cosmetic surgery can have serious cosmetic impacts. Various reconstruction choices exist for deformities such as depression of the soft triangle but choosing the most appropriate treatment in each case remains a challenge. In the case described herein, a patient underwent augmentation rhinoplasty with a silastic implant and experienced implant exposure in the soft triangle area. After implant removal, the patient complained of depression in this area. The authors effectively solved this problem through a de-epithelialized composite tissue graft. In this report, we present this case and review similar cases of reconstruction of the soft triangle.

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.

Purpose: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. Materials and Methods: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (${\geq}$3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. Results: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was $10.7^{\circ}$, $13.8^{\circ}$, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. Conclusion: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

In this study, the skin permeability was measured by adding skin penetrating peptides, arginine oligomers R4(tetra-D-arginine), R6(hexa-D-arginine) to little skin-permeable wrinkle improvement peptides GHK, GHK-Cu, and Pal-GHK liposomes, and the results were analyzed by the following six cases. (1) In cases where only wrinkle improvement peptides GHK, GHK-Cu, and Pal-GHK were contained liposomes; the final cumulative permeations in 24 hours were 6.05%, 7.4%, and 8.83% respectively. (2) In cases where arginine oligomers R4, R6 were added to GHK liposomes; the final cumulative permeations in 24 hours were 13.63% and 7.68%. (3) In cases where R4, R6 were added to GHK-Cu liposomes; the final cumulative permeations in 24 hours were 15.46% and 8.64%. (4) In cases where R4, R6 were added to Pal-GHK liposomes; the final cumulative permeations in 24 hours were 16.9% and 10.67%. (5) In cases where R4 were added to GHK, GHK-Cu, and Pal-GHK liposomes; the final cumulative permeations in 24 hours were 13.63%, 15.46%, and 16.9% respectively. (6) In cases where R6 were added to GHK, GHK-Cu, and Pal-GHK liposomes; the final cumulative permeations in 24 hours were 7.68%, 8.64%, and 10.67% respectively. This experiment showed that skin absorption of GHK was increased by copper ion (Cu2+) and palmitic acid and skin absorption of wrinkle improvement peptides was enhanced by cell penetrating peptides, and R4 showed higher effect than R6 in GHK, GHK-Cu and Pal-GHK. Through this process, we propose broad use and application in wrinkle improvement functional cosmetics by presenting the optimal conditions for increasing skin absorption of GHK, GHK-Cu, thus maximizing its efficacy.

After transplantation of groin free flap was sucessed by the Daniel and Taylor in 1973, the reconstruction of plastic surgery was extensive and universal due to rapidly developement of anatomic study of the donor site and technique of microvascular surgery. The free tissue transfers is possible to be early activity and rehabilitation by one stage operation. It currently available allow transfer of specific tissue quality as bone, muscle, nerve to achieve a functional and cosmetic result as well as the most favorable secondary defect. But free flaps require critical, skillful technique and lengthy operating time. Also it has disadvantage of donor site morbity at the large tissue transfer. Authors were transferred with 107 cases in 103 patients from May 1987 to June 1996, and then we analysed free tissue transfer to acquire more increased sucess rate, satisfactory functional and cosmetic results. The sexual distribution was male prominent in 79 cases(76.7%), female in 24(23.3%) and age was variable distribution from 3 to 76 years old. The cause of defects was most prevalent in trauma of traffic and industrial accident in 51 cases(49%). The common recipient site were lower extremities in 47 cases(43.9%), upper extremities in 28 cases(26.5%), head and neck in 25 cases(23.4%), and trunk in 7 cases(6.5%). The type of transfer were free skin flaps in 46 cases(43%), free muscle or musculocutaneous flaps in 31 cases(29%), free vasculized or osteocutaneous flaps in 10 cases(9.3%), and specilized free flaps in 20 cases(18.7%). The anastomosis of artery was end to end anastomosis in 94 cases(87.9%), end to side anastomosis in 13 cases(12.1%) and all vein was end to end anastomosis. The number of anastomosed vessels were one artery one vein in 62 cases(57.9%), one artery two vein in 45 cases(42.1%) and vein graft was performed only one case. The postoperative mornitoring were used with temperature, color of flap, capillary refilling time, ultrasonogram, bone scan, doppler, and endoscopy. The reexploration was performed in 9 cases(8.4%), and then flap was loss in 3 cases(2.8%). Accordingly overall success rate was 97.2%. The postoperative complication was early vascular occlusion, hematoma, partial necrosis and late bulkiness, scarring, color dismatch etc. Therefore, free tissue transfer is the preferred method of treatment, even through conventional local and distant flaps are available.

Purpose: We reconstructed the thumb with groin flap combined with secondary heterodigital neurovascular island flap and report our 6 cases. Materials and Methods: Between March 2003 and August 2004, 6 degloving thumbs or amputation of thumbs were reconstructed with groin flap combined with secondary heterodigital neurovascular island flap. There ware 4 men and 2 women, and mean age was 42.2 years. The following parameters were evaluated. Results: Recipient thumb was no limitation of apposition. but flexion contracture of interphalangeal joint was about 10 degree in two cases. Average grip power were 80% and average pinch power were 70% that of the normal thumb. The two point discrimination was average 10.5 mm and double sensibility in 2 cases. 2 patients have cold intolerance. Neuroma formation was not made. Cosmetic results as judged by patients were that 4 cases are good and 2 cases are fair. Conclusion: If massive skin defect after degloving thumb or amputation of thumb are present, we consider the numerous methods for reconstruction of thumb. This surgical procedure is good methods because of it's pliability, sensation, satisfactory functional results but major disadvantage are the staged operation and cosmetic effect of the absence of thumb nail.
