RESUMEN
BACKGROUND: Periorbital aging is characterized by dermatochalasis, lateral hooding and malformation of multiple eyelid creases. Rejuvenation of periorbital region is of great concern in aging Asians, especially for the females. However, the conventional subbrow blepharoplasty was indicated for mild or moderate skin laxity. For severe laxity, double-eyelid incision is necessarily to be involved. This study aims to improve the severe upper eyelid dermatochalasis through an extended subbrow single-incision approach with desirable outcomes. METHODS: Patients underwent this surgical method from October 2020 to April 2022 were retrospectively reviewed. The redundant skin and orbicularis oculi muscle were excised through a spindle-like subbrow incision delicately designed in the sitting position. Surgical outcomes were evaluated by heights of designed line from the palpebral margin to the pupil center (HPPC), medial cornea (HPMC), and lateral canthus (HPLC) at different follow-ups. The overall satisfaction score of cosmetic outcomes was assessed by an independent surgeon and patients themselves based on the evaluation of: subbrow scar, eyelid symmetry, lateral hooding lifting, visual block improvement and brow shape. RESULTS: A total of 75 cases were reviewed, including 3 men and 72 women. The preoperative HPPC, HPMC, and HPLC were 4.27 ± 0.40, 4.72 ± 0.45 and 3.41 ± 0.35 mm. The values were postoperatively improved to 7.01 ± 0.46, 6.57 ± 0.34 and 5.69 ± 0.26 mm, respectively, presenting significantly different (p < 0.05). The mean surgeon satisfaction scores were 3.6 ± 0.6 (range, 2.0-4.0), and patient satisfaction scores were 3.5 ± 0.6 (range, 2.0-4.0). No hypertrophic scar, sunken upper eyelids or other complications was found. CONCLUSIONS: The modified subbrow blepharoplasty method is an effective and safe alternative for correcting severe upper eyelid skin laxity, which can achieve both good cosmetic outcomes and functional improvement.

BACKGROUND: Levator aponeurectomy is a common operation for mild to moderate blepharoptosis. The accuracy of ptosis correction relied on intraoperative judgement when patients were under local anesthesia. For patients who must receive the operation under general anesthesia, it would be an issue to determine how much length of levator aponeurosis to shorten. To solve this issue, we collected data from patients who underwent the operation under local anesthesia and concluded an algorithm. METHODS: This single-center, prospective bivariate regression study allocated patients of mild to moderate congenital blepharoptosis who received levator aponeurectomy under local anesthesia. Preoperative MRD1 and levator function, intraoperative amount of levator aponeurotic shortening, and postoperative MRD1 were measured. The follow-up period was right after the operation. RESULTS: Twenty-nine patients were included in this trial. Two subjects exited because of not receiving allocated operation and data of the other 27 subjects (including 34 eyelids) were analyzed. A scatter diagram was drawn where x axis referred to levator function and y axis referred to the ratio of the amount of shortening of levator aponeurosis over the height of MRD1 correction. Linear regression showed y = - 0.2717*x + 5.026, R2 = 0.8553. CONCLUSION: A modified algorithm to predict the amount of shortening of levator aponeurosis based on levator function and height of ptosis correction was concluded with better accuracy and clinical feasibility.

BACKGROUND: With an increasing number of East Asians undergoing blepharoplasty, the number of patients with secondary upper eyelid deformities is increasing. The sunken eyelid deformity is a common deformity after upper blepharoplasty in Asians due to over-resection, retraction, or atrophy of the nasal and central orbital fat pads. Herein, we present a novel procedure, the pendulum movement of orbital fat and retro-orbicularis oculi fat ("POR" technique), for correction of sunken eyelid deformity in secondary Asian blepharoplasty. METHODS: Patients who underwent secondary upper blepharoplasty with the POR technique by the senior author between January 2020 and October 2021 were identified retrospectively. Those with fewer than 6 months of follow-up were excluded. Patient charts and images were reviewed for demographic data, comorbidities, concomitant eyelid deformities, and postoperative complications. Pre- and postoperative aesthetics, including degree of sunken eyelid deformity, were assessed by two independent raters and by self-reported patient satisfaction. RESULTS: Forty-nine consecutive patients were identified, all of whom were female and had grade I or II sunken eyelid deformity. Median follow-up was 8 months. Concomitant deformities included high tarsal crease (N = 31 patients, 63.3%), ptosis (N = 13, 26.5%), and upper eyelid retraction (N = 5, 10.2%). Almost patients had improvement in their eyelid volume, and 95.9% had improvement in their aesthetic rating. Approximately 93.9% of patients were satisfied with the outcome. CONCLUSIONS: The POR technique is an effective technique for correction of sunken eyelid deformity and can be utilized in conjunction with other techniques during secondary blepharoplasty.

Zicaitai (Brassica rapa var. purpuraria (L.H.Bailey) Kitam 1950) is a vegetable crop that boasts a high nutritional value and unique flavor. It originated from Central China and was formed after long-term cultivation and domestication. In this study, we obtained the complete sequence of the chloroplast genome of zicaitai, a circular molecule of 153,483 bp in length. This chloroplast genome consists of a large single-copy (LSC) region (83,282 bp), a small single-copy (SSC) region (17,775 bp), and a pair of inverted repeats (IRs) (26,213 bp). By sequence annotation, 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes were identified in the zicaitai chloroplast. A total of 315 simple sequence repeats (SSRs) were found located in LSC (197), SSC (72), and IR (46), respectively. Phylogenetic analysis based on chloroplast genomes indicated the relationship of zicaitai and the Brassicaceae family, which supports zicaitai as a variety of B. rapa in taxonomy. The results obtained in this study provide insight into further research on Brassica chloroplasts and their phylogeny.
RESUMEN
The impacts of four extraction techniques, including hot water, ultrasonic-assisted, complex enzyme-assisted and acid-assisted methods, on the morphological, physicochemical properties and bioactivities of Asparagus cochinchinensis (poly)saccharides (EACP, WACP, UACP, and AACP) were investigated and compared. The four samples were mainly composed of glucose, fructose, and galactose with molar ratios of 50.8:22.7:4.4 for WACP, 53.9:26.0:5.3 for UACP, 35.6:14.1:21.4 for AACP and 45.0:15.6:9.0 for EACP, respectively. The rheological result showed that ACPs were non-Newtonian fluids. EACP with high purity (97.65 %) had good DPPH, O2- and ABTS+ radical scavenging activities, and significantly promoted the proliferation of the RAW264.7 cells at low concentration. UACP had good Fe2+ chelating ability, radical (DPPH, O2- and OH) scavenging activities, which might be attributed to the existence of triple-helix structure. AACP had high yield, molecular weight (17,477.2 Da), high crystallinity (23.33 %), and good radical (OH and ABTS+) scavenging activities. All four significantly stimulated the transcript expression levels of TNF-α, IL-1ß and IL-6, as determined by RT-PCR. These results suggest that the exploitation and utilization of non-inulin (poly)saccharides extracted by ultrasonic-assisted, complex enzyme-assisted and acid-assisted extraction methods are potentially valuable as effective and natural immune adjuvants and antioxidants.

Zicaitai is a seasonal vegetable known for its high anthocyanin content in both stalks and leaves, yet its reference genome has not been published to date. Here, we generated the first chromosome-level genome assembly of Zicaitai using a combination of PacBio long-reads, Illumina short-reads, and Hi-C sequencing techniques. The final genome length is 474.12 Mb with a scaffold N50 length of 43.82 Mb, a BUSCO score of 99.30% and the LAI score of 10.14. Repetitive elements accounted for 60.89% (288.72 Mb) of the genome, and Hi-C data enabled the allocation of 430.87 Mb of genome sequences to ten pseudochromosomes. A total of 42,051 protein-coding genes were successfully predicted using multiple methods, of which 99.74% were functionally annotated. Notably, comparing the genome of Zicaitai with seven other species in the Cruciferae family revealed strong conservation in terms of gene numbers and structures. Overall, the high-quality genome assembly provides a critical resource for studying the genetic basis of important agronomic traits in Zicaitai.

BACKGROUND: Xerostomia is a salivary gland dysfunction that negatively impacts the life quality of patients; however, there is no effective treatment for xerostomia. Bioengineered organs, generated using stem cells obtained from newborn salivary glands and ligated injury models, are a new organ transplantation strategy that could be feasible for xerostomia treatment. Reconstruction of salivary gland organoids by seed cells obtained from human minor salivary glands will offer theoretical fundaments and technology support for clinical application and organ regeneration research. Herein, we aimed to propose a new method for culturing and enriching adult human minor salivary gland stem cells in vitro in a three-dimensional (3D) environment via Wnt signaling activation. METHODS: Obtained and characterized human minor salivary gland stem cells (hMSGSCs) with self-organization ability were 3D-cultured to generate organoids. We examined hMSGSCs proliferation and colony formation using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays. Telomerase reverse transcriptase staining, flow cytometry, immunofluorescence assay, RNA isolation, RT-PCR, and qPCR were performed to assess hMSGSCs structure and the function of reconstructive organoids in vitro. RESULTS: hMSGSCs showed typical epithelial-like characteristics, such as positive for CD49f and cell KRT expression. hMSGSCs served as adult stem cells in salivary glands and could differentiate into acinar and duct cells. Upon the addition of Noggin, CHIR99021, and Wnt3A to the 3D culture system, hMSGSCs showed higher LGR5 expression and decreased AMY1B and MUC5B expression. Therefore, the Wnt and bone morphogenetic protein (BMP) pathways are important in regulating hMSGSCs self-organization and differentiation. CONCLUSIONS: We showed that the stem cell properties of hMSGSCs in a 3D culture system can be maintained by activating the Wnt signaling pathway and inhibiting the BMP signaling pathway. Our findings contribute new insights on salivary gland organoid generation in vitro.

BACKGROUND: Poor outcomes in functional recovery following upper extremity transplantation are largely due to denervation-induced muscle atrophy that occurs during the prolonged period of nerve regeneration. Growth hormone (GH) has well-established trophic effects on neurons, myocytes, and Schwann cells and represents a promising therapeutic approach to address this challenge. This study sought to confirm the positive effects of GH treatment on nerve regeneration and functional recovery and to evaluate the effects of GH treatment on the immune response in the setting of vascularized composite allotransplantation. METHODS: Rats underwent orthotopic forelimb transplantation across a full MHC-mismatch and received either porcine-derived growth hormone or no treatment (n=18 per group). Functional recovery was measured using electrically-stimulated grip strength testing. Animals were monitored for clinical and subclinical signs of rejection. RESULTS: Neuromuscular junction reinnervation and grip strength were improved in GH-treated animals (p=0.005; p=0.08). No statistically significant differences were seen in muscle atrophy, degree of myelination, axon diameter, and axon counts between groups. The rates of clinical and histological rejection did not significantly differ among groups. CONCLUSIONS: Our findings alleviate concern for increased risk of transplant rejection during GH therapy and therefore support the translation of growth hormone as a therapeutic method to promote improved functional recovery in upper extremity transplantation.
RESUMEN
Vascularized composite allotransplantation (VCA) is a restorative option for patients suffering from severe tissue defects not amenable to conventional reconstruction. However, the toxicities associated with life-long multidrug immunosuppression to enable allograft survival and induce immune tolerance largely limit the broader application of VCA. Here, we investigate the potential of targeted immunomodulation using CTLA4-Ig combined with a biological porcine-derived extracellular matrix (ECM) scaffold that elicits a pro-regenerative Th2 response to promote allograft survival and regulate the inflammatory microenvironment in a stringent mouse orthotopic hind limb transplantation model (BALB/c to C57BL/6). The median allograft survival time (MST) increased significantly from 15.0 to 24.5 days (P = 0.0037; Mantel-Cox test) after adding ECM to the CTLA4-Ig regimen. Characterization of the immune infiltration shows a pro-regenerative phenotype prevails over those associated with inflammation and rejection including macrophages (F4/80hi+CD206hi+MHCIIlow), eosinophils (F4/80lowSiglec-F+), and T helper 2 (Th2) T cells (CD4+IL-4+). This was accompanied by an increased expression of genes associated with a Type 2 polarized immune state such as Il4, Ccl24, Arg1 and Ym1 within the graft. Furthermore, when ECM was applied along with a clinically relevant combination of CTLA4-Ig and Rapamycin, allograft survival was prolonged from 33.0 to 72.5 days (P = 0.0067; Mantel-Cox test). These studies implicate the clinical exploration of combined regimens involving local application of pro-regenerative, immunomodulatory biomaterials in surgical wound sites with targeted co-stimulatory blockade to reduce adverse effects of immunosuppression and enhance graft survival in VCA.

Volatile compounds in wine have a critical impact on the consumers' senses. In this study, the effect of diammonium phosphate (DAP) and glutamine on sulfur-containing volatiles and sensory properties of Chardonnay wine fermented with Saccharomyces cerevisiae yeast were evaluated. Fermentation kinetics was determined by monitoring reducing sugar consumption rates during fermentation. The volatile profile of wines was analyzed by headspace solid phase microextraction (HS-SPME) coupled with gas-chromatography-mass spectrometry (GC-MS). The volatile sulfur compounds (VSCs) were analyzed by HS-SPME-GC-MS/MS. Flavor attributes of wines were assessed by a sensory panel with quantitative descriptive analysis. A total of 53 volatiles, including 6 VSCs, were identified and quantified in the Chardonnay wine. The results suggested that glutamine supplementation at the beginning of fermentation could help to initiate fermentation earlier and promote the formation of isoamyl acetate, phenethyl acetate, ethyl nonanoate, methyl decanoate, diethyl succinate and phenethyl alcohol, isobutanol, while DAP supplementation had no obvious effect on the volatile composition of the resulting wine and fermentation kinetics. PRACTICAL APPLICATION: Suitable nitrogen source is helpful to a healthy fermentation, and can also prevent the off-flavor and regulate aroma profile of wine. This study provides insights on the volatile and sensory characteristics of Chardonnay wines affected by different nitrogen source addition.

BACKGROUND: Pseudoblepharoptosis, which is characterized by ptotic eyelid appearance with normal levator function, is a common abnormality observed in Eastern Asians. Misdiagnosis of pseudoblepharoptosis may lead to inappropriate treatments and unwanted complications. Using the data obtained from a modified levator function examination, this study sought to improve the diagnosis and explore the appropriate treatment of pseudoblepharoptosis based on the typical eyelid anatomy of Eastern Asians. METHODS: This retrospective study included patients with drooping and bulky eyelids who had been preoperatively diagnosed between January 2018 and December 2018 using a modified approach. Debulking of the retro-orbicularis oculus fat and orbital septum fat and release of the ligament-like structure were performed to correct pseudoblepharoptosis without manipulating the levator muscle. The functional and aesthetic outcomes were evaluated postoperatively. RESULTS: The proposed modified approach was significantly more accurate than the traditional technique. Of the patients, 78 (84.8%) and 9 (9.8%) showed good and moderate cosmetic outcomes, respectively. The margin reflex distance 1 value significantly improved from 1.74±0.87 mm preoperatively to 4.56±0.71 mm postoperatively ( P <0.05). Moreover, 179 (97.3%) of the 184 eyelids examined achieved adequate correction. CONCLUSIONS: The modified levator function examination approach used in this study may help improve the diagnosis of pseudoblepharoptosis. Surgical intervention focused on correcting the bulky and drooping upper eyelids and orbital septum may lead to satisfactory outcomes in Eastern Asians with pseudoblepharoptosis without manipulating the levator muscle.

In patients with severe blepharoptosis, the function of the levator muscle is usually weak. Even if a large amount of levator is resected, under-correction and recurrence often occur postoperatively. Frontalis suspension is the first choice for severe ptosis; however, the external orbital lifting force of the frontalis causes non-physiological eyelid movement. Conjoint fascial sheath (CFS) is a fibrous tissue which can provide dynamic movement of upper eyelids and has been applied for the treatment of mild and moderate blepharoptosis in recent years. This study aims to assess the efficacy and safety of CFS suspension combined with levator muscle advancement for treating severe blepharoptosis. A retrospective study included 44 patients (60 eyelids) with severe ptosis who underwent the modified technique. Preoperatively, levator muscle function and margin reflex distance 1 (MRD1) were measured. Surgical outcomes, symmetry results and complications were evaluated postoperatively. At the 12-18 months follow-up, adequate or normal correction was achieved in 56 eyelids (93.3%), and 37 patients (84.1%) presented good or fair symmetry results. The most common complication was conjunctival prolapse, which was observed in six eyelids (10.0%), followed by lid fold deformity and under-correction. No exposure keratitis was recorded. In conclusion, the modified technique can physically elevate the eyelid with limited tissue injury and is effective for the correction of severe ptosis. Both satisfactory functional and esthetic results were achieved, and severe complications (such as exposure keratitis) were not observed.

Distal injury in thumbs and fingers is common in emergency. Although multiple surgical techniques have been introduced for repair purpose, it is still challenging for restoring both good function and cosmetic appearance. The present study reports our experiences on how to reconstruct amputated fingertips in thumbs and fingers using a mini hallux neurovascular osteo-onychocutaneous free flap with favorable outcomes in 15 patients (average age, 27.27 ± 5.43 years old). Follow-up period was 19.47 ± 10.18 months (range, 6-48 months). Digital function was improved indicated by the static two-point discrimination (2-PD) and key-pinch, which were 8.40 ± 1.64 mm (range, 6-12 mm) and 85.37 ± 3.03% (range, 80.2-90.6%) of that of the intact contralateral thumbs and fingers, respectively, after surgery. As to aesthetic outcomes, all reconstructed digits were self-graded as good by patients. 73.3% of the donor halluces were self-graded as good and four halluces (26.7%) were graded as fair. In conclusion, the mini hallux neurovascular osteo-onychocutaneous flap may be used for refined reconstruction of type I amputated injury in thumbs and fingers achieving both satisfactory functional and aesthetic outcomes.

BACKGROUND: Double-eyelid surgery is one of the most common cosmetic surgeries performed in Asians. The palpebral marginal incision technique (PMIT) conceals the incision scar and creates natural-looking double-eyelids. However, the amount of eyelid skin removed by conventional PMIT is limited, which potentially results in an unnatural crease or inferior skin below the palpebral crease that appears swollen. OBJECTIVES: The aim of this study was to introduce a modified PMIT which creates scarless, dynamic, and natural double-eyelids with a limited amount of eyelid skin excision. METHODS: From January 2018 to December 2020, 382 patients (764 eyelids) underwent double-eyelid surgeries with the described technique. The key point was to form a pretarsal levator aponeurotic flap, acting as a soft motor transmission to bridge tarsus, orbicularis oculi muscle, and skin dermis. Satisfaction with the overall aesthetic outcomes-as assessed by surgeon and patients-and complications were postoperatively evaluated at various follow-ups. RESULTS: The mean follow-up period was 7.6 months (range, 6-12 months). Of the patients, 332 (86.9%) reported self-assessment of outcomes as satisfactory and 37 (9.7%) as fair. Secondary operations were required for 13 (3.4%) patients for double-eyelid asymmetry or crease curve malformations. Early-stage hematoma (12 cases) and lagophthalmos (19 cases) were observed and completely recovered within 1 month. CONCLUSIONS: Our modified PMIT technique was capable of achieving scarless and natural-looking double-eyelids with a biomimetic anatomic structure.

BACKGROUND: Polyacrylamide hydrogel (PAAG) has been used globally for breast augmentation, leading to long-term clinical complications. However, whether the infiltrated fibrotic capsule should be removed with PAAG to alleviate the complications remains unclear. This study aimed to ascertain different causes of complications and proper management strategies for PAAG removal in augmented breasts. METHODS: From July 2015 to December 2019, patients who underwent breast augmentation with PAAG and in whom surgical intervention was undertaken for PAAG-associated adverse events at Shanghai Ninth People's Hospital were retrospectively reviewed. Patients were categorized into two groups according to whether the fibrotic capsule was removed (RFC) or not (NRFC). Aesthetic outcomes, PAAG residues, and adverse events were evaluated post-operatively to assess whether important issues pertaining to these arose following fibrotic capsule removal. Tissue histology and PAAG degradation analysis were implemented to investigate immune response, degradability, and toxicity of PAAG. RESULTS: Altogether, 257 patients (88 RFC and 169 NRFC patients) were enrolled. 73.4% and 79.5% of the RFC and NRFC groups showed fairly good outcomes, with no significant difference, respectively. (X2 = 0.0804, p = 0.79) Significant differences were found between two surgical techniques upon patient satisfaction, respectively. (X2 = 3.529; p = 0.0301). Predictor of poor outcomes identified scar (OR, 4.555, p = 0.0019) and PAAG residue (OR, 5.379, p = 0.0003). Predictor of patient satisfaction identified post-operative outcomes (OR, 3.797; 95% CI, 1.860-8.923; p = 0.0002) and surgical technique (NRFC) (OR, 2.519; 95% CI, 1.449-4.434; p = 0.0008). CONCLUSIONS: Both treatment strategies showed good results in our study. Removal of the fibrotic capsule from infiltration of PAAG largely depends on the individual psychological condition, aesthetic expectations, complications, and magnetic resonance imaging results. While PAAG does not degrade in the host's body over time, it may elicit immune reactions and chronic inflammation in the long term.

ABSTRACT: To describe a modified anchored suture technique combined with varied flaps for the repair of paranasal skin defect secondary to melanocytic nevus excision. The feasibility and effectiveness of the technique were discussed. A total of 26 patients (10 male and 16 female) with an average age of 11.1 years were included in this retrospective study. All patients underwent the anchored suture technique. The subcutaneous tissue of the free margin of the cheek flap was sutured to the deep pyriform ligament. The local flaps were designed according to the size and shape of the defect. The diameter of the nevi ranged from 2.8 to 7.5 cm, with most being 3 to 5 cm (50%). Among the 26 patients, 17 patients underwent the anchored suture technique and nonadvancement flap, whereas the other 9 patients underwent the anchored suture technology and advancement flap with auxiliary incisions. Twenty-five patients had a symmetric nasal alar and unapparent scar and were satisfied with postoperative aesthetic outcomes. Thus, the anchored suture method combined with different flaps to repair paranasal defect is an effective and affordable technique to reconstruct paranasal tissue connections.

BACKGROUND: Many people are characterized by a swollen appearance and loose skin of upper eyelids, especially Asians. Retro-orbicularis oculus fat (ROOF) lying in the lateral canthus area is a critical factor of the bulkiness formation. Although several approaches have been reported, most of them intend to remove orbicularis muscle and preaponeurotic fat through a double-eyelid incision, leaving ROOF untreated. Consequently, an unnatural eyelid fold is formed and the lateral supraorbital region remains bloated . METHODS: Sixty-seven patients underwent sub-brow skin excision combined with ROOF resection. The key point was to excise the loose skin and thick ROOF through an incision along with the lower 1/3 of the eyebrow. Surgical outcomes were evaluated 6 months postoperatively by the heights of the designed line from the palpebral margin to the pupil center (HPPC), medial cornea (HPMC), and lateral canthus (HPLC). The pinch test, photographs, and complications were also recorded. RESULTS: The preoperative average HPPC, HPMC, and HPLC were 9.68 ± 1.73, 7.68 ± 1.24, and 6.82 ± 1.12 mm, while the postoperative average measurements were 7.25 ± 0.51, 5.99 ± 0.54, and 5.54 ± 0.61 mm, respectively. The result of the pinch test was improved and postoperative scarring was inconspicuous. Two patients had transient numbness in the eyebrow region that subsided within seven days. Two patients had slight asymmetry of eyebrow position but did not need a second operation. CONCLUSIONS: Sub-brow skin excision combined with ROOF resection is an effective technique for improving upper eyelid bulkiness and skin excess with low revision rates.

BACKGROUND: The transconjunctival technique is an effective approach to mild to moderate blepharoptosis repair that does not involve skin incision. However, accurate surgical manipulation of this method is greatly restricted by poor intraoperative evaluation. OBJECTIVES: The aim of this study was to introduce a modified transconjunctival approach with flexible intraoperative adjustments in order to achieve more accurate ptosis correction. METHODS: Taking a transconjunctival approach, the levator aponeurosis and Müller's muscle were folded with a square-like mattress suture for flexible adjustment and accurate correction. RESULTS: In 18 mild ptosis eyelids, 94.5% (17 eyelids) achieved adequate or normal correction. In 9 eyelids with moderate ptosis, 88.9% (8 eyelids) achieved adequate or normal correction. Of 24 ptosis patients, 23 (95.8%) achieved a good or fair symmetry result. CONCLUSIONS: This study presents a modified transconjunctival technique for repair of mild to moderate ptosis, which is characterized by flexible intraoperative adjustments that produce satisfying functional and aesthetic outcomes.

ABSTRACT: Double-eyelid blepharoplasty, the procedure to create supratarsal crease, has been one of the most popular cosmetic operations in Asia for many years. This study aimed to assess the effectiveness and safety of a surgical procedure using a composite tissue flap for double-eyelid blepharoplasty. A surgical technique was introduced and patients having blepharoplasty with this technique from January 2017 to August 2019 were retrospectively studied. In this technique, a composite tissue flap consisted of the posterior septum and levator aponeurosis was formed and fixed with orbicularis oculi muscle and tarsus. The cosmetic outcomes, patient satisfaction, and complications from the documented medical records were analyzed. Eighty female and 1 male patients had blepharoplasty with the proposed technique and were followed up from 6âmonths to 42âmonths. Six patients were found to have mild blepharoptosis. As for cosmetic outcomes, 71patients were graded as good, 7 patients were graded as fair, and only 1 patient was graded as poor. Those patients who were not graded as good had visible scarring, shallow eyelid crease, or asymmetry. The overall patient satisfaction was as high as 95.1%. Mild hematoma formation occurred in 3 patients and no infection or blepharoptosis was observed. One patient complained of asymmetry and 2 patients complained of unilateral crease fading as the complications. The technique is effective to develop durable and natural-looking double eyelids with minimal complications. It could also be an option for mild ptotic patients who ask for double-eyelid blepharoplasty.
