Purpose: Number of arthroscopic surgery is gradually increasing with development of its equipment and technique. Arthroscopic ankle surgery performed with the traction device has various complications and need more time for preparation. We investigated whether the complication rate increased when surgery was performed without the traction device, and compared the complication rate of arthroscopic surgery with the traction device. Materials and Methods: From January 2009 to June 2012, arthroscopic ankle surgery was performed without the traction device in four hundred eleven cases. There were two hundred sixty-one males and one hundred fifty females. The average age at operation was 35 years (range, 17-56), and the average follow up period was 28 months (range, 12-41). Postoperative symptoms and complications were checked. Results: There were difficulties performing arthroscopic surgery without the traction device in five cases with severe traumatic osteoarthritis. However, after burring and shaving, we had enough space to work on. Superficial peroneal nerve symptom was found in two cases, grooving of talus was found in 11, and saphenous vein injury was found in five. Since preparing for the traction device was unnecessary, we were able to save time with the mean duration of surgery of 50 minutes (range, 30-120). Conclusion: With only manual traction, we could explore the entire ankle joint without damage on cartilage. Yet, skilled arthroscopic technique will be necessary for arthroscopic surgery without the traction device.

The introduction of acellular dermal matrix (ADM) to breast reconstruction has allowed surgeons to reexplore the prepectoral implant placement technique in postmastectomy breast reconstruction. Our institution adopted a novel approach using meshed ADM to lessen the financial burden of increased ADM utilization with the prepectoral breast reconstruction. This is a retrospective, single-center review of two-stage prepectoral breast reconstruction using meshed human-derived ADM for anterior prosthesis coverage. Patient demographics, oncologic data, perioperative characteristics, and complications were examined and reported as means with standard deviations. Cost-saving with the meshed technique was evaluated. Forty-eight patients (72 breasts) with a mean age of 48.5 ± 15.0 years (range 26-70 years) were included in the study. The mean follow-up time was 13.2 ± 4.4 months (range 4.1-25.8 months). Nineteen breasts (24.6%) experienced complications, with seromas being the most common complication (12.5%, n = 9). Expander removal and reoperation occurred at a rate of 8.3 and 9.7%, respectively. The average time to drain removal was 18.8 ± 6.6 days (range 8-32 days). Meshed ADM provided an average cost savings of $6,601 for unilateral and $13,202 for bilateral reconstructions. Our study found that human-derived meshed ADM can be safely used in two-staged prepectoral tissue expander-based breast reconstruction and can result in significant cost savings.
Background Major problems with cervicoplasty by direct skin excision include the subjective nature of skin markings preoperatively and the confusing array of procedures offered. This technique incorporates curved incisions, resulting in a wave-like scar, which is why the procedure is called a "wave-plasty". Methods This prospective study includes 37 patients who underwent wave-plasty procedures from 2004 to 2015. Skin pinching technique was used to mark the anterior neck preoperatively in a reproducible fashion. Intra-operatively, redundant skin was excised, along with excess fat when necessary, and closed to form a wave-shaped scar. Patients were asked to follow up at 1 week, 6 weeks, and 6 months after surgery. Results The mean operation time was 70.8 minutes. The majority (81.3%) was satisfied with their progress. On a scale of 1 to 10 (1 being the worst, and 10 being the best), the scars were objectively graded on average 5.5 when viewed from the front and 7.3 when seen from the side 6 months after surgery. Complications consisted of one partial wound dehiscence (2.3%), one incidence of hypertrophic scarring (2.3%), and two cases of under-resection requiring revision (5.4%). Conclusions In select patients, surgical rejuvenation of the neck may be obtained through wave-like incisions to remove redundant cervical skin when other options are not available. The technique is reproducible, easily teachable and carries low morbidity and high patient satisfaction in carefully chosen patients.

Background Numerous procedures are available for nipple reconstruction without a single gold standard. This study presents a method for reducing donor-site morbidity in nipple reconstruction using a composite nipple graft after transverse rectus abdominis musculocutaneous flap breast reconstruction. Methods Thirty-five patients who underwent nipple reconstruction using a composite nipple graft technique between July of 2001 and December of 2009 were enrolled in this study. To reduce the donor site morbidity, the superior or superior-medial half dome harvesting technique was applied preserving the lateral cutaneous branch of the fourth intercostal nerves. The patients were asked to complete a previously validated survey to rate the color and projection of both nipples, along with the sensation and contractility of the donor nipple; and whether, in retrospect, they would undergo the procedure again. To compare projection, we performed a retrospective chart review of all the identifiable patients who underwent nipple reconstruction using the modified top hat flap technique by the same surgeon and during the same period. Results Thirty-five patients were identified who underwent nipple reconstruction using a composite nipple graft. Of those, 29 patients (82.9%) responded to the survey. Overall, we received favorable responses to the donor site morbidity. Projection at postoperative 6 months and 1 year was compared with the immediate postoperative results, as well as with the results of nipples reconstructed using the modified top hat flap. Conclusions The technique used to harvest donor tissue is important. Preserving innervation of the nipple while harvesting can reduce donor site morbidity.
Five hundred and fory-four women were provided government funded sterilization reversal services with technique of microsurgery at 15 reversal institutions designated by the Korean Association for Voluntary Sterilization since the inception of Female Reversal Program in 1981. A large majority of reasons for requesting reversal surgery was a loss of children, comprising 87.3%, and the mean interval between sterilization and reversal was 33.6 months. Two hundred and ninty-one of 418 women who were post-operatively followed up with the length of 11 months to 11 years, have experienced term dilivery or ,intra-uterine pregnancy, represented 69.6%. Eight cases have experienced ectopic pregnancy and 9 cases spontaneous abortion. The largest number of reversal clients were sterilized by the laparoscopic unipolar coagulation technique and the next largest group was sterilized by the laparoscopic banding technique, representing 59.8% and 28.9% respectively. The highest pregnancy rate, 80.9%, was shown in clients who had undergone laparoscopic banding technique while the lowest, 61.8%, was the group of laparoscopic bipolar coagulation. The most common site of the anastomosis was isthmic-ampullary portion and the next was isthmic-isthmic portion. The highest success rate, 77.8 %, was marked in the isthmic-isthmic anastomosis and the lowest was in the ampullary-ampullary anastomosis, representing 50.0%. A more than 60% of the clients became pregnant within 6 months of their reversal surgery, with the shortest interval being 1 month, the longest 39 months, and the mean 7.6 months. A large majority of the successful cases were pregnancy within 1 year of their reversal surgery, representing 82.1 %. The higher rate of pregnancy, 73.5%, was in the clients undergone reversal surgery within 36 months of their sterilization and the lower pregnancy rate, 64.1 %, was in the clients undergone reversal surgery longer than 37 months of their sterilization.

Background and Objectives Melasma is an acquired pigmentary disorder characterized by brown or dark brown colored macules and patches which mostly involve the face. Compared to nanosecond lasers, picosecond lasers have fewer adverse effects on surrounding tissues and give better results for melanin fragmentation. The purpose of this study was to evaluate the efficacy of the pico-toning technique using a low fluence 1,064-nm Nd:YAG laser on melasma patients. Materials and Methods This study is a retrospective analysis of melasma cases treated using the pico-toning technique from June 2017 to November 2020. Based on photographic images, the modified Melasma Area and Severity Index (mMASI) score was blind evaluated by two independent plastic surgeons. Patient satisfaction was assessed through a 5-point Likert scale questionnaire after treatment sessions. All adverse effects and complications were reviewed based on medical records. Results A total of 23 patients were included in the study. The mMASI scores for baseline and 2 months after the last procedure were 5.1 ± 1.4 and 2.6 ± 0.4, respectively. The mean mMASI score reduced significantly after the treatment session (p < 0.05). The patient satisfaction score with the procedure was 3.8 ± 1.0. The subject satisfaction score and difference in the mMASI score before the procedure and 2 months after the last procedure showed a significant correlation. Adverse effects observed in this study were erythema (n = 1) and edema (n = 1). Conclusion The results of the study show that the pico-toning technique is effective in Asian patients with melasma. We believe that safety was enhanced by using low fluence, and thus better results were achieved with fewer adverse effects.

Background: Complex orbital fractures are impure orbital fractures because they involve the orbital walls and mid-facial bones. The author reported an orbital wall restoration technique in which the primary orbital wall fragments were restored to their prior position in complex orbital fractures in 2020. As a follow-up to a previous preliminary study, this study retrospectively reviewed the surgical results of complex orbital wall fractures over a 4-year period and compared the surgical outcomes by dividing them into groups with and without balloon restoration. Methods: Data of 939 patients with facial bone fractures between August 2018 and August 2022 were reviewed. Of these, 154 had complex orbital fractures. Among them, 44 and 110 underwent reduction with and without the balloon technique respectively. Pre- and postoperative Naugle exophthalmometer (Good-Lite Co.) scales were evaluated. The orbital volume and orbital volume ratio were calculated from preoperative and 6 months postoperative computed tomography images. Results: Among 154 patients with complex orbital fractures, 44 patients underwent restoration with the balloon technique, and 110 patients underwent restoration without it. The Naugle scale did not differ significantly between the two groups, but the orbital volume ratio significantly decreased by 3.32% and 2.39% in groups with and without the balloon technique and the difference in OVR was significantly greater in patients in the balloon restoration group compared with the control group. Postoperative balloon rupture occurred in six out of 44 cases (13.64%). None of the six patients with balloon rupture showed significant enophthalmos at 6 months of follow-up. Conclusion: The balloon rupture rate was 13.64% (6/44 cases) with marginal screw fixation, blunt screws, and extra protection with a resorbable foam dressing. Furthermore, we restored the orbital wall with primary orbital fragments using balloon support in complex orbital wall fractures.

Blunt breast trauma occurs in 2% of blunt chest injuries. This study aimed to evaluate the evidence on breast reconstruction after blunt trauma associated with the use of a seat belt. Also, we describe the first case of breast reconstruction using the Ribeiro technique. In November 2022, a systematic search of MEDLINE, EMBASE, and Google Scholar databases was conducted. The literature was screened independently by two reviewers, and the data was extracted. Our search terms included breast, mammoplasty, blunt injury, and seat belts. In addition, we present the case of a woman with a left breast deformity and her reconstruction using the inferior Ribeiro flap technique. Six articles were included. All included studies were published between 2010 and 2021. The studies recruited seven patients. According to the Teo and Song classification, seven class 2b cases were reported. In five cases a breast reduction was performed in the deformed breast with different types of pedicles (three superomedial flaps, one lower flap, one superior flap). Only one case presented complications. The case here presented was a type 2b breast deformity in which the lower Ribeiro pedicle was used successfully without complications during follow-up. Until now there has been no consensus on reconstructive treatment due to the rarity of this entity. However, we must consider surgical treatment individually for each patient. We believe that the Ribeiro technique is a feasible and safe alternative in the treatment of posttraumatic breast deformities, offering very good long-term results.

Backgrounds/Aims: Splenectomy is the most frequently performed procedure as definitive management or as part of shunt surgery or devascularization in portal hypertension. Splenectomy is technically challenging because of the frequent coexistence of multiple collateral varices, splenomegaly, poor liver function, and thrombocytopenia. Early arterial ligation and late mobilization (EALDEM) is the traditional method for splenectomy in portal hypertension. Early spleen mobilization offers good control of the hilum. We aim to compare the effect of the early mobilization and delayed arterial ligation (EMDAL) technique with that of the conventional splenectomy technique in patients with portal hypertension. Methods: During the study period from September 2011 to September 2022, 173 patients underwent surgical intervention for portal hypertension at our institution. Among these patients, 114 underwent the conventional method of splenectomy (early arterial ligation and late splenic mobilization) while 59 underwent splenectomy with the EMDAL technique. Demographics were compared between the two groups. Intraoperative and postoperative outcomes were analyzed using the Mann-Whitney test in each group. A minimum follow-up of 12 months was performed in each group. Results: Demographics and type of surgical procedure were comparable in the two surgical method groups. Median blood loss was higher in the conventional group than in the EMDAL method. The median duration of surgery was comparable in the two surgical procedures. Clavien-Dindo grade III/IV complications were reported more frequently in the conventional group. Conclusions: The splenic hilum can be controlled well and bleeding can be minimised with early mobilization and delayed arterial ligation.

Apical sealing with proper retrograde filling material and technique is the key factor for successful apical surgery. In order to provide impeccable apical sealing and healing, various mechanical and chemical characteristics of retrograde filling material is required. MTA has been used as the gold standard of retrograde filling due to its unprecedented advantages. As MTA has long setting time and difficult handling properties, premixed putty type bioceramic material has been newly developed. For efficient retrofilling with premixed putty type biocreamic material, 'Lid technique' was also proposed. The following cases present apical surgery using newly developed premixed putty type bioceramic material with Lid technique.
