Composite grafting remains a technique which is used reluctantly and without great hope of success. In the recent two years, unexpectedly good result of composite graft was gained from 30 cases. The purpose of our study is to identify factors influencing success and to overlook long-term problems from a cosmetic and a functional view point. A retrospective review and a questionnaire about 30 fingers of 29 patients which were operated for composite graft at Kyongju hospital of Dongguk university from March 1997 to February 1999 were carried out. In all cases of composite grafting, tie-over dressing and heat lamp were applied and left for five days. And following result and conclusion were obtained. 1. 24(80%) of 30 finger tips replaced as composite graft were survived completely or partially. 2. At children with an age range 1 to 14, the survival rate (100%) of composite grafted tips was higher than that (75%) at adults. So, patient's age was important factor for success. 3. The type of injury was more important factor than the level of amputation. The survival rate(100%) of tips to cutting injury was higher than that(75%) of tips to crushing injury. 4. The delay in time from amputation and replacement did not significantly correlate with the survival rate. But, all tips replaced within 3 hours were survived completely or partially. 5. Even if partial necrosis on grafted tips was present, a result of long-time conservative treatment with minimal debridrement was excellent. Especially in children, the tips with conservative treatment showed normal appearance, several months later. 6. Cosmetic and functional results were better in child group and in groups with higher survival rate. Most common problem in cosmetic aspect was a short digit and that in functional aspect was a tender tip. 7. As a heat lamp increased blood supply, we could obtain better outcome.

2.Usefulness of the Keystone Flap in Lower Extremity Reconstruction in Patients with Anterior Tibial Artery Variation: A Case Report
Journal of Wound Management and Research 2024;20(1):96-100
Reconstruction of lower extremity wounds in patients with abnormalities in vascular anatomy is often challenging. A 71-year-old man was admitted to our hospital after sustaining two contact burns on his right leg while sleeping on an electric blanket. Fourth-degree burns amounting to approximately 3% of total body surface area were confirmed, with eschar formation on the right instep and pretibial area. Both wounds on the lower leg required flap reconstruction. In addition, the patient had anterior tibial artery hypoplasia. We considered a two-flap reconstruction method that should leave the source artery and muscle intact and generally has a good prognosis. A peroneal artery perforator-based keystone flap was used on the right lower leg, and a right dorsalis pedis island flap on the foot dorsum. Surgery was performed successfully, and at 8 months postoperatively, the patient walked naturally and had no complaints of discomfort. Additionally, cosmetic results were satisfactory. Accordingly, we introduce a surgical method that is useful in cases similar to that described.

Background:
Quantitative skin assessments have transitioned from subjective evaluations to objective approaches. However, clinical application has remained limited due to high costs and reliance on specialized equipment. High-intensity focused ultrasound and radiofrequency are the two most widely used noninvasive modalities for skin tightening and wrinkle improvement. This study investigated investigate the efficacy of artificial intelligence (AI)-based skin analysis as a more accessible and cost-effective tool for assessing skin firmness and wrinkle improvement.
Methods:
A retrospective analysis was conducted on 34 patients treated simultaneously with high-intensity focused ultrasound and bipolar radiofrequency between January and February 2025. AI-based skin assessments, evaluating firmness and wrinkle scores, were obtained pre-treatment, immediately post-treatment, and at a 2-month follow-up. Standardized clinical photographs were independently evaluated by two blinded human raters. Logistic regression and correlation analyses were conducted to determine alignment between AI and human evaluations.
Results:
AI analysis showed significant improvements in both firmness and wrinkle scores immediately after treatment and at the 2-month follow-up (P<0.05). Human evaluations demonstrated high inter-rater agreement (Cohen’s κ=0.72–0.91). Logistic regression analyses indicated that changes in AI scores significantly predicted human-rated treatment effectiveness at both time points (area under the curve [AUC] for firmness=0.86; AUC for wrinkles=0.73–0.93). Spearman correlation coefficients and the Mann-Whitney U test further supported strong alignment between AI and human assessments.
Conclusions
This study validates the clinical utility of AI-based skin analysis as a reliable quantitative measure for evaluating wrinkle improvement and skin tightening following energy-based rejuvenation treatments. Its predictive validity aligns well with expert human judgment, particularly at delayed follow-up.

PURPOSE: Unilateral breast reconstruction after mastectomy confront the challenges of recreating a natural appearing breast mound and achieving symmetricalness of the breasts. If the patient's remaining breast is large compared to reconstructed breast, the most common procedure is reduction mammoplasty of the large breast side. The authors experienced a new method of breast reconstruction using the excess breast tissue from the contralateral breast after breast reduction. METHODS: The excess tissue from the contralateral breast after vertical reduction mammoplasty with superior pedicle and remaining lower breast tissue were transferred to the mastectomy site breast through the subcutaneous tunnel on the chest wall. The main blood supplies of the flap are perforator branches of the 4th, 5th and 6th anterior intercostal artery. After elevating and detaching the flap on the lower lateral area of the breast, the turned over flap is fixed on the upper portion of the chest wall of the mastectomy site. RESULTS: On two cases of the breast reconstructions, remaining excess breast tissue from reduction mammoplasty was transferred to the contralateral breast side as pedicles. Both patient and operator were satisfied with the outcome of the reconstruction as the breasts were symmetrical and in natural shape. CONCLUSION: We have performed unilateral breast reconstruction using the excess breast tissue after reduction mammoplasty of the contralateral breast. As Oriental women's breasts are relatively smaller than those of Caucasian women, delayed breast reconstruction cases of Oriental women with large breasts(macromastia) seem to be ideal for this procedure.

None of the reports of delayed infection mentioned a latent period exceeding 13 months. we report an infection that developed 18 months after implantation of an absorbable plate. A 16-year-old adolescent girl had undergone reduction and fixation with an absorbable plate for Lefort I and zygomaticomaxillary complex fractures 18 months prior at our hospital. In her most recent hospital visit as an outpatient, abscess was observed in periocular area. Computed tomography revealed sinusitis with an abscess above the infraorbital rim. Wound culture yielded methicillin-resistant Staphylococcus aureus . Despite conservative treatments, wound state did not improve. Therefore, our department decided to perform surgery. Absorbable plate had been mostly absorbed but remained a bit. Bony depression of infraorbital rim and mucosal exposure of maxillary sinus anterior wall were observed. After the surgery, the patient recovered. We believe that the reason the wound infection and sinusitis manifested at the same time is because of several factor such as alcohol abuse, smoking, and mucosal exposure of maxillary sinus anterior wall. Absorbable plate takes 9 months to 3 years to be completely absorbed, thus we suggest studies with a follow-up of at least 3 years be undertaken to determine the outcomes of patients with many risk factors.

Sebaceous carcinoma is a rare malignant tumor differentiated from the adnexal epithelium of sebaceous glands and forms less than 1% of all cutaneous malignancies. We present a case of a 93-year-old woman with a rapidly growing mass on the right cheek. Initial histiopathologic finding was basal cell carcinoma. The mass was widely excised and superficial parotidectomy was performed while preserving the facial nerve branches. The resulting defect was covered with a transposition flap from the ipsilateral posterior auricular area and the donor site was closed primarily. However, histopathologic examination of the excised mass showed a poorly differentiated sebaceous carcinoma with a clear resection margin. The diagnosis of sebaceous carcinoma can be difficult to make at initial presentation. This report describes a rare case of a rapidly growing extraocular sebaceous carcinoma, which resulted in a good treatment outcome, and provides a review of relevant literature.
