RESUMO
The limited detection rate of plain radiography (as low as 75%) for glass particles within the softs renders the conventional C-arm visualization method ineffective in intraoperative scenarios. The authors report the successful use of intraoperative navigation to visualize and extract multiple small glass fragments located deep within the temporal fossa and beneath the zygomatic arch. A 25-year-old man presented with a deep facial laceration, suspected injury to the temporal branch of the facial nerve, and a 2×2 cm foreign body beneath the sphenoid bone near the left zygomatic arch. The initial surgery removed most of the glass; however, two 4 mm fragments remained near the skull base. Using intraoperative navigation, a 3 cm incision was made, and a navigating stylet was used to locate and remove the foreign bodies. In conclusion, intraoperative navigation is a precise method for removing small, imperceptible glass fragments from challenging anatomic areas, thus reducing the need for extensive dissection compared to conventional approaches.
RESUMO
BACKGROUND: Even though scars are major issues for patients who undergo facial lacerations, programs for their prevention and early management are not well established. The purpose of this study was to evaluate the clinical outcomes of prophylactic scar assessments and early scar interventions in patients with lacerations. PATIENTS AND METHODS: A total of 116 patients underwent suture line and scar prevention treatment in the emergency room from 2014 to 2015. In the retrospective study, 46 patients who met all the criteria were included in the study. They were assigned to one of the following two scar prevention programs: the standard scar program for prevention, which included taping, silicone sheets, and ointments, and the multimodality scar program for treatment, which included triamcinolone, botulinum toxins, or CO2 fractional lasers. The patterns of early scar program were investigated for the standard scar prevention program and the multimodality scar management program, and we evaluated the scar assessment scores of the patients at 3 and 6 months. RESULTS: Scar scores for the patients who received multimodality scar management showed statistically significant improvements in Patient Scar Assessment (PSA) scales, Stony Brook Scar Evaluation Scales (SBSES), Vancouver Scar Scale (VSS) scores, and Visual Analog Scar (VAS) scales (the p values were 0.008, 0.007, 0.017, and 0.01, respectively). CONCLUSION: The multimodality scar program is more effective for scar prevention than the standard scar program.

BACKGROUND: Polydioxanone (PDO) is absorbable thread which is usually used for wound closure and face lifting. These days, PDO thread is used increasingly for aesthetic purposes such as correction of facial wrinkles, laxity and even rhinoplasty in many oriental traditional medicine clinics. As rhinoplasty with PDO thread increases, complications also increase. In this study, we will report on the clinical features of patients who got rhinoplasty using PDO thread. METHODS: From August 2018 to July 2019, seven patients (three males and four females) visited our clinic for complications after rhinoplasty with PDO thread. We checked ultrasonography and laboratory findings including wound cultures. We used conservative treatment using antibiotics and performed surgery on three patients. RESULTS: Three patients experienced severe complications with open wounds, abscesses and skin necrosis. Four patients experienced mild complications including redness and thread exposure without open wounds. The location of infection included the nasal tip and inner lining. Six patients had a history of rhinoplasty before. On ultrasonography, abscess formation was seen around the implant inserted before. During the operation, PDO thread cannot be seen except in one patient. CONCLUSIONS: PDO thread cannot be seen in radiologic findings and can cause severe infections like abscess formation with open wounds. In severe infections, massive debridement with the removal of the implant would be required. PDO thread is absorbed usually after six months; mild infection can be controlled by the conservative treatment. The best is not undergoing rhinoplasty with PDO thread for patients who had implants because of potential side effects.

PURPOSE: A linear surgical scar, when located in the head and neck region, can be a significant cosmetic concern. Laser skin resurfacing with a fractional laser and a pulsed dye laser has been proven to be useful for treating such scars. As alternatives, we used a classic ablative CO2 laser in continuous mode with a 1-mm spot size and a 595-nm Nd:YAG laser. We investigated the effect of the combination of the continuous CO2 laser and 595-nm Nd:YAG laser and compared it to the effect of fractional CO2 laser monotherapy on linear scars. METHODS: This was a retrospective, case-controlled study designed to compare the efficacy between fractional CO2 laser therapy and combination therapy with a conventional CO2 laser in continuous mode and a 595-nm Nd:YAG laser. Treatment efficacy was evaluated by two different scar scales: the Stony Brook Scar Evaluation Scale (SBSES) and the modified Vancouver Scar Scale (mVSS). Laser treatments were performed every month until the 6th month after surgery. RESULTS: The SBSES and mVSS scores improved over time in both the monotherapy and the combination therapy (P < 0.001). No significant differences were found between the therapies for all the subcategories of the SBSES. However, among all the subcategories of the mVSS, pigmentation showed a better prognosis with combination therapy (P = 0.04). CONCLUSION: Monotherapy and combination therapy can provide similar positive effects on linear scar improvement after repeated treatment, whereas combination therapy exerts more favorable anti-pigmentation effects than monotherapy. The combination of a continuous ablative CO2 laser with a 595-nm Nd:YAG laser can be used as a favorable alternative to a fractional CO2 laser. The 1-mm spot size of the CO2 laser beam may mimic the fractional laser form and offer more effective results for linear incision scars.

OBJECTIVE: Retrograde infections often occur with excessive or incomplete drainage of exudate, or as a result of adherence of dressings to wounds. Dialkylcarbamoyl chloride (DACC) irreversibly binds to bacterial surfaces and physically removes bacteria when dressings are changed. Chlorhexidine acetate-soaked paraffin gauze provides a moist wound-healing environment. We hypothesise that when DACC is combined with chlorhexidine acetate-soaked paraffin gauze, wound healing times decrease. METHOD: From January 2013 to June 2015, medical records were retrospectively evaluated in 60 patients who underwent split-thickness skin grafts (STSG). Patients were divided into two groups: a 'thick skin group' and a 'thin skin group'. These two groups were further subdivided into a control group, where conventional foam dressings were applied to wounds, and an experimental group, where chlorhexidine acetate-soaked paraffin gauze with DACC was applied (DACC group). We compared the wound healing time between these subgroups. Differences in infected wound healing times were also compared. The Mann-Whitney test was applied to compare wound healing times between groups. RESULTS: Epithelialisation duration was significantly shorter in the DACC group. The control group had longer wound healing times, regardless of wound size. In the thick skin group, the median healing duration was 12 days in the control subgroup, compared with 9.5 days in the DACC subgroup (p=0.049). In the thin skin subgroup, the median healing duration in the control group was 18 days, compared with 10 days in the DACC subgroup (p=0.013). CONCLUSION: Application of DACC and chlorhexidine acetate-soaked paraffin gauze to skin graft donor sites can shorten healing times and is effective in treating infected wounds.

BACKGROUND: Recent research on stromal vascular fraction (SVF) has demonstrated the presence of numerous growth factors that aid in tissue regeneration and suggest the potential for scar treatment. This study was conducted to clinically show that adding stem cells can improve the surgical outcomes of scar formation. METHODS: Between March 2014 and February 2016, 17 patients underwent injections of fat and highly condensed SVF simultaneously with scar reduction surgeries and 15 patients received scar revision with or without simultaneous application of highly condensed SVF (4.90 × 107 stem cells/ml) at our institution. Clinical photographs were taken before and after surgery, and the scars were graded using the following standard scales: the Observer Scar Assessment Scale (OSAS), Stony Brook Scar Evaluation Scale (SBSES), Vancouver Scar Scale (VSS), and Visual Analog Scale (VAS). RESULTS: All patients showed improvement, registering significant increases in scar tissue scores (P < 0.05 in all four scoring systems). Patients in the SVF group showed more improved outcomes than patients in the non-SVF group for all scar tissue scores except the SBSES (OSAS, P = 0.029; SBSES, P = 0.281; VSS, P = 0.001; VAS, P = 0.021). Subcategories of these scales reflected more favorable outcomes in terms of height and pliability; however, there was no significant change in vascularity. CONCLUSIONS: SVF injections enhance tissue regeneration by contributing stem cells and growth factors to improve outcomes in scar revisions or tissue grafts. Harvesting the SVF through liposuction also provides a cosmetic benefit. Significant SVF-related gains in the scoring of scars indicate the merit of SVF as an aspect of conventional scar management.

BACKGROUND: Calf contouring continues to be popular among Northeast Asians. Calf hypertrophy and distorted leg contours are stressful to many women. Several calf reduction techniques such as a selective neurectomy or calf muscle resection have been attempted, but have inconsistent results. OBJECTIVES: This study was designed to demonstrate improved outcomes when combining a selective neurectomy with simultaneous liposuction. METHODS: A total of 780 patients with hypertrophic calves underwent calf reduction from January 2002 to December 2010. Of these, 193 patients were treated by selective neurectomy with simultaneous liposuction. Calf hypertrophy with a circumference below 34 cm was defined as mild, calves with a circumference of 34 to 38 cm were defined as moderate, and a calf circumference above 38 cm was defined as severe. In all groups, patients whose pinch test was above 2 cm underwent a simultaneous liposuction. RESULTS: Twenty-eight cases (14.5%) were defined as mild, 72 (37.3%) were moderate, and 93 (48.2%) were severe. Over an average of 8.7 months of postoperative follow up, the reduction in calf circumference averaged 3.7 cm in the mild group (11.1%), 4.0 cm in the moderate group (10.7 %), and 4.3 cm in the severe group (10.7%). Overall, 97.5% of patients were satisfied with the results. There were no severe complications including functional problem of lower extremity reported. CONCLUSIONS: The shape, type, and fat distribution of the hypertrophic calves were considered in our patient analysis. A selective neurectomy with liposuction was performed on 193 patients. This technique allowed for a successful calf reduction and improved the patient's aesthetic satisfaction without any reported functional complications.

BACKGROUND: There have been few studies of the action of epinephrine injected into scalp tissue, or whether the action of epinephrine differs according to vascular anatomy within the same surgical field. Effective perioperative control of bleeding is critical during hair transplantation due to its time-consuming nature. OBJECTIVE: To identify the vasoconstriction time of epinephrine by concentration and injection site in the scalp tissue. METHODS: Twenty-five volunteers were injected with epinephrine at concentrations of 1:400,000, 1:200,000, 1:100,000, and 1:50,000 in the path of the supraorbital artery on the anterior hairline in the midfrontal area (Point A) and at the frontotemporal junction of the frontal hairline (Point B). Laser Doppler was used to measure scalp blood flow, and vasoconstriction time at Points A and B with each concentration of epinephrine was recorded. RESULTS: The duration of action of epinephrine increased in direct proportion with the concentration of epinephrine. The duration of vasoconstriction was shorter at Point A than at Point B, but this difference was only statistically significant at an epinephrine concentration of 1:50,000. CONCLUSION: The vasoconstriction time of epinephrine in the scalp correlated positively with concentration, and the duration of vasoconstriction was longer at Point B than at Point A.

Osteonevus of Nanta is a melanocytic nevus displaying secondary ossification and carrying a potential for malignancy. A solitary occurrence is reported herein, presenting as a flesh-colored papule following laser ablation.A 56-year-old woman sought treatment for a minor papular growth of the cheek. This lesion had developed at the site of prior CO2 laser ablation done elsewhere to eradicate a pigmented nevus. The patient's medical records and histopathology report were obtained after surgical excision.Histologically, a completely excised osteonevus of Nanta was evident, marked by an intradermal nevus with subjacent osseous metaplasia. Clinical presentations of these lesions may vary, but the potential for malignancy remains.

BACKGROUND: A rise in cosmetic procedures has seen the use of fillers become more prevalent. Complications resulting from use of fillers have prompted introduction of various medical and surgical interventions. Recently, stem cell therapies have become more widely used as a new treatment option for tissue repair and regeneration. METHODS: We utilized adipose-derived stem cells (ASCs) for tissue regeneration in patients with filler-related complications such as necrosis. All 12 patients were treated with ASCs and some patients had additional treatment. After relief of symptoms, wound surface area was compared in terms of pixel numbers and scar condition was evaluated using the Vancouver Scar Scale (VSS). RESULTS: In general, we achieved satisfactory resolution of filler-related complications in a short period of time without serious side effects. The average number of days from stem cell treatment to symptom relief was 7.3 days. The proportion of wound surface area from photographic record was 4.39 % before treatment, decreasing considerably to 1.01 % following treatment. Last, the VSS showed almost all patients scored below 3, with two patients receiving scores of 7 and 8; the average score was 2.78 (range from 0 to 8). CONCLUSIONS: ASCs are a new treatment option for post-filler injection wounds such as necrosis. Using stem cells, we were able to obtain satisfactory results in a short period of time without complications requiring surgical procedures. We suggest stem cell injections could be used as the first option for treatment of complications from filler injections.

Extraocular sebaceous carcinoma that occurs on sebaceous gland is a rare malignant cancer with unknown causes and nonspecific clinical characters, but with distinct pathology and immunohistochemical finding. In Kangnam Sacred Heart Hospital, there was a case that the result of preoperative punch biopsy was squamous cell carcinoma and malignant proliferating trichilemmal tumor, but that of postoperative permanent biopsy was sebaceous carcinoma. The type of tumor, differentiation, location, and aesthetic results are considered to get both recurrence-safe and aesthetically pleasing result. Various flaps were considered, and modified face-lift flap, forehead rotation flap, orbicularis oculi V-Y advancement flap were planned. There were no sign of recurrence of cancer or functional and aesthetical deformities 6 months after the surgery.

Soft tissue filler injection has been a very common procedure worldwide since filler injection was first introduced for soft tissue augmentation. Currently, filler is used in various medical fields with satisfactory results, but the number of complications is increasing due to the increased use of filler. The complications after filler injection can occur at any time after the procedure, early and delayed, and they range from minor to severe. In this review, based on our experience and previously published other articles, we suggest a treatment algorithm to help wound healing and tissue regeneration and generate good aesthetic results with early treatment in response to the side effects of filler. Familiarity with the treatment of these rare complications is essential for achieving the best possible outcome.

The purpose of this study was to devise an expanded ischemic flap model and to investigate the role of AMD-3100 (Plerixafor, chemokine receptor 4 inhibitor) in this model by confirming its effect on mobilization of stem cells from the bone marrow. Male Sprague-Dawley rats were used as an animal research model. The mobilization of stem cells from the bone marrow was confirmed in the AMD-3100-treated group. The fractions of endothelial progenitor cells (EPC) and the vascular endothelial growth factor receptor (VEGFR) 2+ cells in the peripheral blood were increased in groups treated with AMD-3100. The expression of vascular endothelial growth factor (VEGF) was increased in response to expansion or AMD injection. The expression of stromal cell derived factor (SDF)-1 and VEGFR2 were increased only in unexpanded flap treated with AMD-3100. Treatment with AMD-3100 increased both the number and area of blood vessels. However, there were no statistically significant differences in the survival area or physiologic microcirculation in rats from the other groups. This endogenous neovascularization induced by AMD-3100 may be a result of the increase in both the area and number of vessels, as well as paracrine augmentation of the expression of VEGF and EPCs. However, the presence of a tissue expander under the flap could block the neovascularization between the flap and the recipient regardless of AMD-3100 treatment and expansion.

After restoration of orbit wall fracture, preventing sequelae is important. An absorbable mesh is commonly used in orbit wall fracture, yet it has limitation due to orbit sagging when bony defect is larger than the moderate size (1 × 1 cm2). In this study, the authors present a satisfactory result in treating orbit wall fracture larger than the moderate size with a combination of absorbable mesh and demineralized bone matrix.From 2009 to 2012, 63 patients with bony defect larger than the moderate size, who were treated with a combination of absorbable mesh and demineralized bone matrix, were reviewed retrospectively. The site of bony defect, size, and applied amount of demineralized bone matrix were reviewed, and a 2-year follow-up was done. Facial computed tomography scans were checked preoperative, immediate postoperative, and 2-year postoperative.Among the 63 patients, there were 52 men and 11 women. Mean age was 33.3 years. The most common cause was blunt blow (35 cases); mean defect size was 13.36 × 12.82 mm2 in inferior wall fracture and 20.69 × 14.41 mm2 in medial wall fracture. There was no complication except for 3 cases of infraorbital nerve hypoesthesia. A 2-year follow-up computed tomography showed that the surgical site preserved bony formation without herniation. In treating moderate-sized bony defect in orbit wall fracture, absorbable mesh and demineralized bone matrix can maintain structural stability through good bony formation even after degradation of absorbable mesh.

PURPOSE: With the increasing use of microsurgical techniques in clinical work, regular laboratory training in these techniques has become essential. Several specialized materials have been used for this purpose. We investigated whether effective training could be provided with greater convenience and less expense using fresh chicken thighs. Also, we present the histologic characteristics of chicken femoral neurovascular structures. METHODS: The femoral neurovascular bundles of fresh chicken thighs were dissected. Microanastomosis of vessels and nerves were performed with the aid of a microscope. Tissue from the midthigh of 8 chickens was examined histologically. RESULTS: It was found to reduce the time taken to perform anastomoses using the chicken thigh model with statistically significance. The mean diameters (± standard deviations) of the arteries, veins, and nerves were 2.04 ± 0.17 mm, 1.45 ± 0.06 mm, and 1.24 ± 0.08 mm, respectively. The observed tunica adventitia to media ratio was 1:1 and multiple nerve fascicles were wrapped in a single epineurium. Microsurgery training with this material provides several advantages: ready availability, minimal expense, no scheduling or location limitations, neurorrhaphy training, no need for special facilities for animal care or anesthesia, and no need for the trimming of adventitia. CONCLUSION: The femoral neurovascular bundles of chicken are an appropriate and effective model for teaching and practicing microsurgery.

BACKGROUND: It is generally accepted that the developmental deficiency of the unilateral perinasal skeleton, cartilages, and skin originates from the secondary cleft nasal deformity. To date, numerous attempts have been made to correct these deformities, but no clinical data are available about the simpler, comprehensive, and patient-customized methods for correction of the secondary cleft nasal deformity. In the correction of Asian patients with secondary cleft nasal deformity, the clinical experience with the simplified Tajima method and several adjunctive procedures based on the severity of the disorder were retrospectively reviewed. METHODS: During the period January 1982 to May 2009, 197 consecutive patients underwent repair through the modified Tajima method followed by several adjunctive procedures. RESULTS: These series had no recurrence requiring surgery except for cases in which the nasal ala was depressed to some extent. The mean degree of patient satisfaction as rated on the 5-point Global Aesthetic Improvement Scale (GAIA) was 3.88 ± 0.59. CONCLUSIONS: Various types of surgical procedures were performed using the modified Tajima method depending on the degree of alar cartilage displacement. These procedures were effective in achieving symmetry of the nasal tip for patients with secondary unilateral cleft lip.

UNLABELLED: BACKGROUND; Successful skin grafting requires immobilization and compression of the graft site. Traditional dressing methods such as tie-over dressings, cast splints, and elastic bandages are bulky in the joint area and can cause abrasion, maceration, and even circulatory insufficiency. OBJECTIVE: To test the effectiveness of a hydrocolloid dressing, which provides a moist wound environment, is flexible and elastic, and adheres well to skin, for securing skin grafts. MATERIALS & METHODS: A case-controlled retrospective study was conducted of 62 patients treated with skin grafts at Myongji Hospital between February 2007 and September 2009. Patients were treated with additive hydrocolloid dressing (n=31) or bolster dressing and splinting (n=31). RESULTS Treatment duration for the hydrocolloid group was significantly less than for the bolster dressing and splinting group (mean ± standard deviation 8.32 ± 1.82 days vs 13.55 ± 5.30 days, p<.001). No significant differences were observed between the groups with regard to age, sex, or graft size. The hydrocolloid group included one case with complication (stitch abscess), whereas the bolster and splinting group included eight cases with complications of partial skin loss. CONCLUSIONS: Additive hydrocolloid dressing is a stable, effective method of securing skin grafts and is associated with better graft survival as measured by shorter treatment time and lower complication rate. The authors have indicated no significant interest with commercial supporters.

Nasal bone fractures are the most common type of facial fracture. Closed reduction has been used as the standard treatment modality for nasal fractures for many years. In cases of nasal fracture with lacerations at the fracture sites, bioabsorbable/metallic plate or interfragment wire fixation can be used with accurate alignment through the openings created by the lacerations. However, in cases of severe comminuted nasal fractures that are difficult to drill and fix, this type of fixation may not be feasible. We performed in 5 patients open reduction with internal fixation through laceration openings using the biomaterial Greenplast (Greencross Corporation, Seoul, Republic of Korea; human plasma fibrinogen, thrombin, aprotinin, and calcium chloride) under general anesthesia. Both structural and aesthetic outcomes were satisfactory. Open reduction through laceration openings and internal fixation with fibrin glue under general anesthesia may be a simpler and more effective method than those currently in general use for the repair of complicated comminuted open nasal fractures.

PURPOSE: There have been numerous attempts to use pharyngoesophageal reconstruction to restore swallowing function. Much controversy exist over reconstruction after total or partial pharyngectomy, and there is also debate over whether to continue with the reconstructive procedure with a narrow strip of remnant mucosa or complete it after total pharyngectomy. We analyzed the utility of omega-shaped radial forearm free flap (RFFF) using the narrow remnant posterior pharyngeal wall. METHODS: Patients in group 1 (n = 12) had a narrow remnant pharyngeal wall with a width of less than 3 cm. Those in group 2 (n = 35) had a remnant pharynx with a width larger than 3 cm. The incidence of fistula, stricture, and swallowing difficulty were evaluated. Swallowing difficulty was graded using a 7-point visual analog scale. All circumferential hypopharyngeal reconstruction with tubed RFFF, pectoralis major flap, and jejunal free flap were also compared with group 1. RESULTS: All flaps survived, and 1 fistula (8%) was detected in group 1. Compared with tubed RFFF (46%) and tubed pectoralis major flap (57%), this is a relatively low rate of fistula formation. In group 1, normal diet was possible in 92% of patients, but 1 patient can tolerate a liquid diet only. In group 2, normal diet was possible in 80% of patients. As for swallowing difficulty, the median visual analog scale score for both groups 1 and 2 was 6 points. When comparing different flaps, stricture and fistula rate was 0 and 8% in group 1, 15 and 46% in tubed RFFF, 43 and 57% in tubed pectoralis major flap, and 33 and 5% in jejunal flap, respectively. CONCLUSIONS: We performed all surgeries taking care not to transgress the wide excision principle with the remnant hypopharyngeal wall. For remnant lesions greater than 3 cm, patch-type RFFF was performed, whereas for those less than 3 cm, omega-shaped RFFF was done. We achieved fairly good results in both groups without total resection of the narrow remnant hypopharyngeal wall.
