Botulinum neurotoxin A injection is a popular noninvasive alternative for the treatment of masseter hypertrophy. This study was conducted to identify a safe injection volume to avoid sunken lateral cheek after botulinum neurotoxin A injection in the masseter muscle.One milliliter or 0.5 ml of indocyanine green was randomly injected into either side of the masseter muscles of 18 fresh cadaver heads. The bilateral spreads of indocyanine green within the masseter were observed by a fluorescence imager. The masseters were then dissected, and the spreading distance was measured.Dye spreading showed an oval shape parallel to the long axis of the masseter muscle. The lower edges of the masseters were all stained with indocyanine green. The upward spreading exceeded the mouth corner-tragus line in 94.44% (17/18) of the masseters on the 1-ml side, and 11.11% (2/18) of the masseters on the 0.5-ml side. The spreading area and upward spreading distance on the 1-ml side (9.95 ± 0.48 cmThe spread of indocyanine green within the masseter occurs in direct proportion to its volume. A bolus of 1 ml easily exceeded the mouth corner-tragus line and cause sunken cheek.

The ageing in the mid-face involves volume deficiency in multiple anatomical units, including the zygomatic arch, infraorbital region, medial and lateral cheek and nasolabial fold (NLF). Hyaluronic acid (HA) is extensively used in the minimally invasive procedures of mid-face rejuvenation.MD CodesAnatomical dissection and ultrasound imaging help us look back on the injection methods and anatomical principles of MD CodesThe treatment is threefold: (1) the bolus injections, for lifting purposes, are performed at the most depressing point along the zygomatic arch, zygomatic eminence, the prominent optimal point in the zygomatic region, the most depressed point of upper NLF with 0.2-0.3 ml HA. (2) The linear injections, featuring facial contouring refinement, are performed at the deep fat pad of the medial cheek and infraorbital region with 0.4 ml HA. (3) The linear injections, featuring volume replacement, are performed at the subcutaneous fat layer of lateral cheek and NLF with 0.8 and 0.4 ml HA.MD CodeThis journal requires that authors assign a level of evidence to each article.

Background This article presents a new method using a dermis-outer orbicularis fascia-orbicularis-levator (DOOL) fixation technique for double-eyelid blepharoplasty. Methods Our surgical technique preserves the preorbicular venous network (POVN) and uses mattress sutures to fix the dermis, outer fascia of the orbicularis oculi muscle, and orbicularis oculi muscle with pretarsal levator aponeurosis (DOOL). Between January 2016 and July 2018, 335 patients were treated with this POVN-preserving DOOL technique (321 women and 14 men; mean age, 29.6 y). The patients were followed up for 6-30 months. The complications were documented, and the overall outcomes of the upper eyelid folds were evaluated by both surgeons and patients as good, fair, or poor. Results Among 335 patients, 307 (91.6%) had good results, 17 (5.1%) had fair results, and 11 (3.3%) had poor results. Postoperative complications included partial (n=4) or complete (n=3) loss of the double-eyelid line and asymmetric folds (n=4). Hypertrophic/depressed scars did not occur. Conclusions With less invasiveness and secure internal fixation, the DOOL fixation technique with POVN preservation can achieve a stable and natural double-eyelid appearance.

Summary Purpose In addition to women, men also undergo breast surgeries, and early studies on the blood supply of breasts are nearly all conducted in female subjects. The vasculature of the male breast is seldom studied. Understanding the male-specific blood supply of the breast is important for pre-operative planning and reducing complications. The purpose of this retrospective study is to fill the gap in the literature by describing the main blood supply and its orientation in the male breast. Methods We retrospectively evaluated thoracic computed tomographic angiography (CTA) data from January 1, 2017 to July 30, 2019. Single or multiple dominant arteries and their origins were traced, and the artery route and orientation related to the nipple-areola complex (NAC) were revealed through data analysis of the images. Results Totally, 284 breasts were included. Most breasts were supplied by a single dominant artery (196, 69%), among which the lateral thoracic artery (LTA; 119, 41.9%; type I) and internal thoracic artery (ITA; 63, 22.2%; type II) were the most common arteries. A minority of breasts were supplied by vascular anastomoses formed by dual arteries (17, 6.0%; type III), and in 25.0% of breasts, no specific dominant artery was found (type IV). The predominant artery distribution was evaluated. Conclusion This study cohort of male thoracic CTA provided and analysed the elaborate vascular anatomy of the NAC region. Our results favour inferior periareolar incision in regard to diminished vascular-related complications in male surgeries without pre-operative vascular evaluation. This study also suggests that super-lateral or lower-lateral-based pedicles can reserve more vasculature.

BACKGROUND As a promising treatment for lymphedema, vascularized lymph node transfer (VLNT) is associated with a risk of iatrogenic lymphedema. Intra-abdominal vascularized lymph node flap has been increasingly applied to minimize complication. METHODS PubMed, EMBASE, Web of Sciences, and Cochrane databases were searched systematically. Clinical articles describing the application of intra-abdominal flaps to treat lymphedema were included. Study characteristics, patient demographics, and operative details were recorded. Primary outcomes were recorded as circumference/volume reduction, episodes of cellulitis reduction and lymph flow assessment. Secondary outcomes were recorded as donor-site complication and recipient-site complication. RESULTS Twenty-one studies met the inclusion criteria with 594 patients in total. Donor-sites of flaps were omental/gastroepiploic, jejunal, ileocecal, and appendicular. The mean reduction rate ranged from 0.38% to 70.8%. Significant reduction in infectious episodes was reported in 10 studies. The pooled donor-site complication rate was 1.4% (95% CI, 0%-4.1%; I2 = 40%). The pooled recipient-site complication rate was 3.2% (95% CI, 1.4%-5.5%; I2 = 39%). The most common donor-site complication was minor ileus requiring prolonged nasogastric tube replacement. No donor site lymph disfunction occurred. CONCLUSION Intra-abdominal VLNT is an effective technique for patients with lymphedema with no obvious impairment to donor-site lymph function, as long as the operation is properly performed.

Female genital cosmetic surgery consists of multiple procedures, usually including labiaplasty, clitoral prepuce reduction, labia majora augmentation, and vaginoplasty. The reasons for women to undergo these surgeries can be categorized as functional and aesthetic ones. In this study, we introduced the modified vaginoplasty with acellular dermal matrix (ADM) and briefly reviewed our experience in the combination of multiple procedures to achieve the optimal effect.

The inframammary approach is one of the most commonly used incisions in breast augmentation. There are many suture methods for inframammary incisions; however, no one method has proven optimal. We modified the traditional three-layer suture method according to the inframammary fold (IMF) cadaver dissection results. This study aims to investigate whether using a modified suture method can improve postoperative outcomes.Cadaver dissections were performed in order to clarify the anatomy of the IMF. From June 2013 to December 2017, a retrospective study of primary breast augmentation patients subjected to the inframammary approach was conducted. Patients were divided into two cohorts: the traditional suture method and the modified suture method. The patient's demographics, specifics of breast augmentation procedures, complications, and scar assessment were analyzed. Univariate and multivariable analyses were used to determine differences between the two cohorts.One hundred eighty-four patients were included: 75 patients were subjected to the traditional suture method, and 109 patients were subjected to the modified suture method. Wound-related adverse events (p = 0.026) and IMF-indented scarring (p = 0.014) were significantly different between the two groups. Multivariable analysis showed that the suture method was the most influential factor related to IMF-indented scarring (OR = 16.9), followed by BMI (OR = 2.9).We defined a new suture method for the inframammary incision in primary breast augmentation. This modified suture method reduces the occurrence of wound-related adverse events and IMF-indented scarring.

BACKGROUND Nipple-areola complex is a naturally hyperpigmented skin area which can be involved in vitiligo. But limited study focused on the treatment of nipple-areola complex vitiligo, and few methods were proven to be effective. In this study, we aimed to explore the feasibility and efficacy of ReCell® on vitiligo in the nipple-areola complex area. METHODS Medical records of patients with vitiligo involving nipple-areola complex and underwent ReCell® treatment from October 2016 to April 2020 were retrospectively reviewed. The repigmentation rate of the nipple-areola complex and other breast area were calculated under the Wood's light at each follow-up. The grade of repigmentation and patient-reported satisfaction rate were also evaluated to prove the effect of ReCell® on vitiligo of breast and especially in the nipple-areola complex area. RESULTS A total of 18 patients were included in this study. No surgical complications were reported. The mean postoperative repigmentation rate in the nipple-areola complex area (3rd-month, 78.7 ± 5.8%; 6th-month, 87.6 ± 5.1%; and 12th-month, 96.1 ± 3.5%) was significantly higher than that in the other breast treatment area (3rd-month, 70.4 ± 6.9%; 6th-month, 84.2 ± 5.7%, and 12th-month, 93.2 ± 3.6%). All patients showed good or excellent grades at the last follow-up, and 94.4% of them considered the overall treatment results satisfactory. CONCLUSIONS ReCell® is a feasible and efficient treatment strategy in the nipple-areola complex vitiligo.

Hereditare Ichthyosen sind eine Gruppe von Genodermatosen, die entweder als nichtsyndromal oder syndromal klassifiziert werden. Nichtsyndromale Ichthyosen und das Keratitis-Ichthyosis-Taubheitssyndrom (keratitis, ichthyosis and deafness syndrome, KID-Syndrom) pradisponieren fur Pilzinfektionen. Diagnostik und Behandlung von Pilzinfektionen bei Ichthyosen sind herausfordernd. In dieser Ubersicht fassen wir publizierte Ichthyose-Falle mit Pilzinfektion aus den letzten 50 Jahren zusammen. Bei Patienten mit Ichthyose in Kombination mit Pilzinfektion traten atypische Manifestationen wie Alopezie, Papeln und bruchige Nagel auf. Verschiedene Pathomechanismen wurden vorgeschlagen, darunter Mutationen Ichthyose-relevanter Gene, die uber verschiedene Signalwege zur Storung der Hautbarriere fuhren. Erkrankungen des Immunsystems, wie Atopie oder Storungen der angeborenen Immunitat, tragen ebenfalls zur Anfalligkeit bei. Bestimmte Pilze konnen die Immunabwehr umgehen. Ausgedehnte und wiederkehrende Pilzinfektionen sind bei Ichthyose-Patienten nicht selten, was die Heilung erschwert und systemische antimykotische Therapien erfordert. Etablierte und neue Ichthyosebehandlungen zielen darauf ab, die Barrierefunktion der Haut zur Vermeidung von Pilzinfektionen zu verbessern. Daher ist der enge Zusammenhang zwischen Ichthyose und Pilzinfektionen in der klinischen Praxis von entscheidender Bedeutung und erfordert arztlicherseits mehr Aufmerksamkeit. Weitere Studien sind erforderlich, um beteiligte Mechanismen und sinnvolle Behandlungsstrategien zu erforschen.

Localized scleroderma (LoS) is an autoimmune connective tissue disorder leading to serious long-term aesthetic impairment on patients. Objective evaluation methods are badly needed to facilitate the evaluation of the surgical treatment on individual patients and clinical studies. To develop and assess the reliability and validity of Peking Union Medical College LoS facial aesthetic index (PUMC LoSFAI). Twelve experts devoted their time and resources in the development and validation. LoS patients in the stable phase were recruited. Reliability and validity was then assessed. LoS patients were evaluated by two plastic surgeons using PUMC LoSFAI and LoS skin damage index (LoSDI). The PUMC LoSFAI comprises 4 domains for the local assessment (surface area of lesion, dyspigmentation, skin thickness and soft tissue atrophy) and 3 domains for the overall assessment (facial symmetry, proportion and profile) to describe LoS facial aesthetic impairment. Face-Q was completed by patients at each visit. Thirty-two LoS patients had 96 visits, during which 138 lesions were assessed. PUMC LoSFAI and 7 domains demonstrated substantial to excellent inter- and intra-rater reliability (ICC 0.995, κw 0.72-0.91, r 0.85–0.99, respectively). Seven domains considered to be important to extremely important variables (mean rank 3.2–3.8) had high I-CVI (> 0.78) and S-CVI (0.93). PUMC LoSFAI correlated excellently with LoSDI (r = 0.933, P

Botulinum toxin type A (BoNT-A) injection is a popular cosmetic procedure in East Asian countries, and there are multiple types of toxins on the market. Whether different toxin types induce different changes in the masseter has not been studied.We aimed to investigate and compare the changes induced by injection of different types of BoNT-A in the masseter.Upon retrospective review of clinical records and routine ultrasound examination results of patients who underwent BoNT-A injection, four groups were set for comparison: unapproved toxin, OnabotulinumtoxinA, LanbotulinumtoxinA, and non-injected. Clinical records and ultrasound images were collected. Ultrasound images were taken in both horizontal and coronal planes. Elasticity of the masseter muscle was also investigated by measuring the surface wave speed.A total of 24 patients were included (six patients per group). All patients were young females. For the non-injected group, the deep inferior tendon was clear and the muscle bundles were arranged, with little fibrous content. Patients who received unapproved toxin injection showed highly disarranged muscle and fiber bundles, with much fiber content present. The changes in OnabotulinumtoxinA and LanbotulinumtoxinA groups were in between those in the non-injected and unapproved toxin groups. Muscle rigidity was the highest in the unapproved toxin group, and generally higher in injected groups compared with the non-injected group.Different types of BoNT-A may induce different changes in the masseter.

Objective We retrospectively evaluated the efficacy and safety of keystone-designed perforator island flaps for chest keloid reconstruction. Methods We reviewed consecutive patients who received keystone flap reconstruction after chest keloid resection between January 2017 and February 2018. The patient demographic data, defect size, flap size, complications, and recurrence were recorded. Results Thirty-eight patients were evaluated in this retrospective case series. After keloid resection, dimension of wound defects was 5.5-9.5 cm × 9.5-12.5 cm, with an average dimension of 7.3 cm × 10.7 cm. The dimension of keystone flaps was between 6-10 cm × 20-34.5 cm, with an average dimension of 7.5 cm × 25.5 cm. The flaps healed smoothly without any complication. There was no keloid recurrence with 15 months of follow-up. 89.4% of the patients had good outcome with no apparent scarring, and 10.6% patients had satisfactory outcome with localized scarring. Conclusions Keystone-designed perforator island flap is an effective and reliable method for reconstruction following chest keloid resection.

Background Botulinum toxin type A (BTA) injection is a widely-used procedure to correct cosmetic problems caused by muscular hyperactivity. "Cobblestone chin" refers to the appearance of remarkable chin creases caused by mentalis contraction. Aims The aim of this case report is to raise the awareness of paradoxical bulging after BTA injection in mentalis. Patient/methods A 26-year-old female asked for cosmetic correction of the "cobblestone chin". BTA injection was performed routinely to the mentalis muscle. However, on the second day after injection, an unusual paradoxical bulging at chin was presented. Results We speculated that the imbalanced relaxation of mentalis caused by improper injection and uneven diffusion of BTA is responsible for the bulging. After a supplementary injection of BTA in the remaining hyperactive muscle fibers based on the ultrasound examination, the bulging was relieved and chin contour improved significantly. Conclusion Injection of BTA in mentalis should cover the whole thickness of the muscle to prevent imbalanced paralysis and paradoxical chin bulging, especially in severe mentalis hyperactivity cases.

Background and objectives Giant juvenile fibroadenoma (GJF) is a rare benign tumor that disfiguring affects the breast shape and quality of life of patients. This study aimed to report the experience of GJF management. Methods A Wise-pattern skin reducing tumor resection followed by immediate breast reconstruction with a dermal flap pocket was used. The long-term outcomes were assessed retrospectively by BREAST-Q questionnaire from 2008 to 2018. Results The study included eight patients with GJF. All patients achieved satisfactory results without severe complications. The BREAST-Q revealed that postoperative scores for satisfaction with breasts (69.3 ± 17.6) and sexual wellbeing (62.3 ± 27.6) were higher than the normative scores. The psychosocial wellbeing (69.7 ± 14.6) and physical wellbeing-chest (86.8 ± 13.0) scores were slightly lower than the normative scores. Conclusion Although GJF is a benign tumor, it should be surgically removed. And the Wise-pattern skin reducing tumor resection with immediate breast reconstruction is a proper way to improve patients' satisfaction with breast size and shape and quality of life.

Background Due to the relatively higher tendency of postsurgery scars, insufficient cartilage support, and low surgical acceptability, nasal defect repair with forehead flap in Asian patients needs further study. Objective We aim to determine the necessity of tissue expansion, timing of pedicle division, and the importance of cartilage scaffold reinforcement and scar prevention at the donor site during nasal reconstruction in Asian patients with paramedian forehead flap. Methods A retrospective analysis was performed on patients who underwent nasal reconstruction with forehead flap at our hospital from January 2013 to January 2018. The demographical information, surgery details, and postoperative complications of all patients were recorded. The reconstructed nose, scars, and eyebrow deformities were evaluated by digital photographs, and the overall satisfaction of the patients was documented. Results The study included 15 patients (7 males and 8 females). All nasal defects involved at least two aesthetic units and included seven full-thickness defects. Only one patient underwent two revision operations. Complications like hematoma, infection, and necrosis were not detected, except in one patient with partial necrosis of the flap. All patients were satisfied with the reconstructed nose and did not report any respiratory dysfunction. No obvious scars or eyebrow deformities were observed. Conclusion Three-stage full-thickness forehead flap should be used to repair nasal defects in Asian patients, with immediate cartilage scaffold reconstruction at stage one and reinforcement at stage two. Botox injection into the forehead can refine the scar.

Background Cutaneous melanoma is the most aggressive form of skin cancer. It accounts for approximately 5% of all cutaneous malignancies and is currently responsible for the majority of skin cancer-related deaths. However, the exact mechanisms responsible for the occurrence of melanoma, in particular the invasive growth in normal skin or muscle tissue, remain unknown. Materials and methods miR-3662, a microRNA is a potential tumor suppressor targeting zinc finger E-box binding homeobox 1 (ZEB1), which functions as a key regulator of the epithelial-mesenchymal transition (EMT) process. This microRNA was identified using an online database (miRDB) and expression was confirmed by Western blot analysis. Quantitative polymerase chain reaction (qPCR) was used to examine whether miR-3662 inhibits the EMT process in the aggressive melanoma cell line, A375, through the modification of the expression of invasion-related genes in A375 cells. The effects of miR-3662 on the in vivo growth of A375 cells were examined in a nude mouse model. Results Using virtual screening of the miRDB database, miR-3662 was shown to target the 3' untranslated region (UTR) of the ZEB1 gene. Expression of miR-3662 via a lentivirus vector significantly decreased protein levels of ZEB1 and inhibited the growth of A375 cells in vitro and in vivo. The reduction in ZEB1 expression induced by miR-3662 resulted in EMT inhibition in A375 cells and decreased the relative expression of metastasis genes. Conclusion Down-regulation of ZEB1's expression via miR-3662 lentivirus vectors significantly decreased the in vitro and in vivo growth of the highly aggressive melanoma cell line A375.

This article presents a new method using a dermis-outer orbicularis fascia-orbicularis-levator (DOOL) fixation technique for double-eyelid blepharoplasty.Our surgical technique preserves the preorbicular venous network (POVN) and uses mattress sutures to fix the dermis, outer fascia of the orbicularis oculi muscle, and orbicularis oculi muscle with pretarsal levator aponeurosis (DOOL). Between January 2016 and July 2018, 335 patients were treated with this POVN-preserving DOOL technique (321 women and 14 men; mean age, 29.6 y). The patients were followed up for 6-30 months. The complications were documented, and the overall outcomes of the upper eyelid folds were evaluated by both surgeons and patients as good, fair, or poor.Among 335 patients, 307 (91.6%) had good results, 17 (5.1%) had fair results, and 11 (3.3%) had poor results. Postoperative complications included partial (n=4) or complete (n=3) loss of the double-eyelid line and asymmetric folds (n=4). Hypertrophic/depressed scars did not occur.With less invasiveness and secure internal fixation, the DOOL fixation technique with POVN preservation can achieve a stable and natural double-eyelid appearance.This journal requires that authors assign a level of evidence to each article.

Background With the growth in the popularity of facial filler injections, increased numbers of severe adverse events, such as cerebral embolism, have been reported. Objectives The aim of this article was to summarize the clinical manifestations and proposed mechanisms of filler-induced cerebral embolism (FICE). Methods A literature review was performed with the search keywords “filler injection,” “hyaluronic acid,” “fat graft,” “cerebral infarction,” “cerebral embolism,” “stroke,” “cerebrovascular infarction,” “disorders of consciousness,” and “hemiplegia.” Results Among the 43 cases of FICE enrolled from 35 articles, 37 patients were female, and 6 were male. Twenty-nine of these patients had received fat grafting, and 12 hyaluronic acid injection. Most FICE patients had been injected in the glabella, followed by the temporal, forehead, and nasal areas. Among 30 patients injected under local anesthesia, 43.33% presented with neurologic symptoms during the procedure. The main symptoms were consciousness disorders and hemiplegia. Most of the embolization sites were in the middle cerebral artery, followed by frontal lobe infarction and anterior cerebral artery infarction. Three patients developed cerebral hemorrhage after embolism. Twenty-six patients presented with newly acquired vision loss. The management for FICE cases included embolectomy, thrombolysis, decompressive craniectomy, antiplatelet/anticoagulant therapy, and symptomatic and nutritional treatment. Nearly half of the patients recovered or exhibited improved neurologic manifestations but not visual loss. Five patients died. Conclusions FICE is a severe complication following facial filler injection. Careful prevention, timely identification, and treatment are crucial to decreasing the morbidity and mortality of FICE. Level of Evidence: 4

Aims: Systemic light-chain (AL) amyloidosis is a multisystemic disorder leading to multiple organ dysfunction and mortality that is often caused by cardiac involvement. Soluble suppression of tumorigenicity 2 (sST2) is a novel biomarker identified for risk stratification of heart disease. The aim of this study was to investigate the value of circulating sST2 levels in prognosis and mortality risk assessments for the AL amyloidosis population.Methods and Results: A total of 56 patients diagnosed with AL amyloidosis were enrolled in Peking Union Medical College Hospital (PUMCH) from January 2015 to May 2018. The relationships between the clinical parameters and overall survival (OS) and risk factors for disease progression were assessed. Additionally, receiver operating characteristic (ROC) curves, Kaplan–Meier analysis, and Cox hazard models were performed to explore the predictive value of sST2 in mortality rates. We found that the median OS of all patients was 7.3 [interquartile range (IQR) 4.4, 15.9] months. The median baseline sST2 level was 12.2 (IQR 5.1, 31.1) ng/ml, and the sST2 high group had more severe patients with a higher Mayo stage. In the ROC analysis, the area under the curve (AUC) was 0.728 [95% confidence interval (CI) 0.603–0.853] for sST2 to predict the outcomes of AL amyloidosis patients, and the optimal cutoff value was 12.34 ng/ml (sensitivity 80.2%, specificity 61.1%). Moreover, in multivariate Cox proportional hazards regression analysis, sST2 acted as an independent predictor of poor functional outcome in patients with AL amyloidosis.Conclusion: In AL amyloidosis patients, sST2 was a strong and independent prognostic biomarker for all-cause mortality, providing complementary prognostic information of a novel scoring system for risk stratification.

Background For the patients seeking secondary upper blepharoplasty, a static double-eyelid fold featuring an immobile lower flap and depression of the fold is common. Objectives In this study, the authors propose a novel technique of reconstructing pretarsal tissue defects (PTDs) to converting static folds to dynamic folds. Methods A total of 203 patients with static folds underwent revision surgery. After complete adhesion release of the lower flap, a PTD was identified, which was defined as an area deficient of orbicularis oculi muscle in front of the tarsal plate. If the width of the PTD was over 2 mm, tissue transfer was performed to reconstruct the PTD, usually with a free retro-orbicularis oculus fat graft or a pretarsal orbicularis oculi flap. Results Among the 105 patients with severe static folds, 67 received retro-orbicularis oculus fat grafts and 38 received orbicularis oculi muscle flaps. This technique converted a static fold into a dynamic fold. The surgery satisfaction rate was 86.7%. Complications included partial fold loss (n = 7, 3.4%), complete fold loss (n = 3, 1.5%), sunken upper eyelids (n = 5, 2.5%), multiple folds (n = 3, 1.5%), an unnatural curve of the double fold (n = 5, 2.5%), and asymmetric folds (n = 4, 2.0%). Conclusions To convert a static fold to a dynamic fold, we devised a technique that releases adhesion of the lower flap and reconstructs the PTD with retro-orbicularis oculus fat graft or an orbicularis oculi muscle flap. Our study achieved a high patient satisfaction rate, and the resulting fold mimicked the dynamics of the congenital double-eyelid fold. Level of Evidence: 4

BACKGROUND No reports of the potential areas of surgeons' aesthetics in blepharoplasty. AIMS To explore the association between the surgeons' own double eyelid morphology and their aesthetics and surgical outcome. METHODS An investigation of 1605 patients was carried collecting the data of double eyelid shape, based on which to propose a preliminary double eyelid classification for analyzing the aesthetics of surgeons. Ten double eyelid surgical cases were randomly collected from each surgeon according to the inclusion criteria, whose double eyelid shape, ideal shape, the selection tendency of surgical approach, most cared factor during surgery, and design concept of eyelid shape were collected. Structural equation modeling (SEM) was performed to assess the association between participants' double eyelid shape, aesthetics, and blepharoplasty outcome. RESULTS Fifty-three double eyelid surgeons were enrolled for study, whose double eyelids shapes mostly were obviously fan-shaped (37.74%) and low-parallel eyelid (26.42%), and the ideal shapes were obviously fan-shaped (41.51%) and high-parallel eyelid (24.53%). 54.72% of the subjects preferred to use the full-incisional method. 45.28% cared for long-term outcome most. Regarding blepharoplasty outcome style, 49.06% of the subjects preferred obviously fan-shaped type and 24.53% for high-parallel type. SEM showed that aesthetics rank increased by 0.692 points for surgeons' shape (P

Muscle-sparing vertical rectus abdominis myocutaneous (MS-VRAM) flaps are widely used in pelvic reconstruction. Aiming at optimal reconstructive outcomes, flap design and modification should be individualized to restore various kinds of defects.Summarize an empirical strategy about MS-VRAM selection for different pelvic and perineal reconstructions.Thirty patients who underwent total pelvic exenteration and pelvic reconstruction surgery from 2009 to 2017 were enrolled. The patients were divided into four groups according to the type of MS-VRAM-based flap used in the procedure: the modified long vertical flap (n = 10), the wrapping flap (n = 6), the de-epithelialized flap (n = 6), and the cork flap (n = 8). The follow-up period was 1 year after the surgery. Flap size, drainage volume, postoperative satisfaction, and complications were recorded, and postoperative photographs were collected.All of the patients achieved satisfying effect under the targeted reconstruction strategy. Of the four groups, the accurate cork flap finally acquires higher satisfaction, the shortest hospital stay, and the least total drainage volume. Meanwhile, the incidence of complications was not increased compared with the other groups.A new reconstructive strategy for pelvic reconstruction was established. Functional or non-functional reconstruction was accomplished by using various MS-VRAM flaps. Among them, the cork flap is the most economical flap to reconstruct pelvic floor defects with minimal tissue requirement and donor trauma.

Background Full lips are beauty standards. Botulinum toxin A (BTA) paralyzes the orbicularis oris muscle to achieve the eversion of the lip, and thus makes the lip look plump. Aims This study presents three cases of BTA injection to the lip and evaluates the possible changes in the labial morphology and the lip surface area. Methods Three patients received a total of 4U BTA injection at the vermilion border of the upper lip. Vectra® H1 3D imaging system was used to capture 3D photographs of the lips before injection and two weeks after injection. Eight linear distances and the upper lip surface area were measured. Anthropometric measurements before and after injection were compared. Results Patients displayed a larger upper vermillion height (P = .038) and a smaller cutaneous upper lip height (P = .024). There was a trend for a larger upper lip surface area, but not statistically significant (P = .109). Symptoms of slight perioral muscular palsy and mouth incompetence lasted about one month in three patients. Conclusion BTA helps to enlarge the upper lip and shorten the philtrum. The BTA injection can be an option for lip enhancement with caution.

Inherited ichthyoses are a group of genodermatoses classified as either nonsyndromic or syndromic. Nonsyndromic ichthyoses and keratitis, ichthyosis and deafness (KID) syndrome predispose to fungal infection. The diagnosis and treatment of fungal infections underlying ichthyoses are challenging. In this review, we summarize reported cases of ichthyosis with fungal infection over the past 50 years. Atypical manifestations such as alopecia, papules and brittle nails occurred in patients with ichthyosis combined with fungal infection. Various pathogenic mechanisms have been implicated, including mutations of ichthyosis-related genes leading to disruption of the skin barrier via multiple pathways. Host immune disorders, including atopy and abnormal innate immunity also contribute to susceptibility. Specific fungi may escape the immune response. Extensive and recurrent fungal infections are not uncommon in patients with ichthyosis, making a cure more difficult and increasing the need for systemic antifungal therapy. Traditional and new ichthyosis treatments aiming to improve skin barrier function could help prevent fungal infection. In conclusion, the close relationship between ichthyosis and fungal infection is of vital importance in clinical practice and requires more attention from physicians. More studies are required to investigate the mechanisms and explore useful treatment strategies.

In this paper, a three-dimensional model of the melt conveying section of a PVC Wood-Plastic single-screw extruder has been constructed and the corresponding mesh file has been established through Mesh Superposition Techniques (MST). Then the rheological experimental results and material viscosity model parameters obtained by polymath software have been finally used for numerical simulations which are based on Polyflow software package with PVC wood plastics as raw materials. With the contrastive discussions of the simulation results, the effects of screw arris cross section shapes on the flow fields in the melt conveying section of the PVC wood-plastics single-screw extruder have been analyzed.
