RESUMO

BACKGROUND: Mandibular fractures are common facial fractures, and contemporary management of mandibular condylar fractures is controversial. The purpose of this study was to compare the outcomes of patients who sustained a mandibular condylar fracture between 2016 and 2020, who were managed by either open or closed techniques. The outcomes of this study were: post-operative facial nerve function, occlusion, and maximal mouth opening. METHODS: This study is a retrospective multicentre cohort study which assessed clinical records for 246 patients with mandibular condyle fractures in three hospitals in Perth, Western Australia. The primary outcome measure was changes in post-operative facial nerve function. RESULTS: One hundred and thirty-two patients underwent open reduction and internal fixation (ORIF), and 114 patients had closed management. The overall rate of temporary facial nerve injury following ORIF was 3.28%. The overall rate of permanent facial nerve injury was 0.82%. Sialocoele occurred in 2.46% of all patients who underwent ORIF. 6.14% of patients had persisting malocclusion across both groups. There was a statistically significant association between the degree of fragment shortening and facial nerve injury (P = 0.0063), with more facial nerve changes in the group with 5 mm or greater of fragment shortening. CONCLUSIONS: There is still significant debate over the management of mandibular condylar injuries. This study demonstrates a similar rate of temporary and permanent facial nerve injury as previously described, as well as a similar rate of sialocoele occurrence. Further prospective studies may provide clarity about important characteristics that will help guide decision making for mandibular condylar fractures.

RESUMO

BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is widely used in breast reconstruction and the profunda artery perforator (PAP) flap as alternative. However, the difference between the two flaps in smaller breast reconstruction remains lacking, in particular, the donor site complications. In this case series, the results of small breast reconstruction (≤300 g) using PAP or small DIEP flaps were explored. METHODS: Unilateral immediate breast reconstruction using a free PAP flap or small DIEP flap (≤300 g) from 2011 to 2021 were reviewed retrospectively. Excluding patients with delayed reconstruction, 28 patients, including 17 PAP flaps and 11 small DIEP flaps were enrolled. Flap characteristics, breast and donor site complications, and revision surgeries were reviewed. BREAST-Q™ was used for quality-of-life assessment. RESULTS: Compared with a small DIEP flap, a PAP flap was narrow (7.5 ± 1.1 vs. 10.6 ± 0.7 cm, p < .001), short (20.0 ± 2.6 vs. 25.5 ± 1.8 cm, p < .001) and had a shorter pedicle (5.9 ± 1.6 vs. 9.1 ± 1.0 cm, p < .001). There were no significant differences in acute and late complications of wound healing and fat necrosis, but the average number of revisions in the PAP group was significantly higher (1.9 ± 1.3 vs. 0.8 ± 1.4, p = .041). Patient-reported outcomes using BREAST-Q™ displayed no significant difference between the two groups. CONCLUSION: The outcomes of PAP and small DIEP flaps at the breasts and donor sites are satisfactory, despite that a higher tendency of donor site complications in PAP flap and more aesthetic refinement required in the PAP group. The overall outcomes are acceptable.

RESUMO

BACKGROUND: Improving the philtrum morphology of patients with a secondary cleft lip deformity has been a challenge in cleft care. Combining fat grafting with percutaneous rigottomy has been advocated for treatment of volumetric deficiency associated with a scarred recipient site. This study assessed the outcome of synchronous fat grafting and rigottomy for improvement of cleft philtrum morphology. METHODS: Consecutive young adult patients ( n = 13) with a repaired unilateral cleft lip who underwent fat grafting combined with rigottomy expansion technique for enhancement of philtrum morphology were included. Preoperative and postoperative three-dimensional facial models were used for three-dimensional morphometric analyses including philtrum height, projection, and volume parameters. Lip scar was qualitatively judged by a panel composed by two blinded external plastic surgeons using a 10-point visual analogue scale. RESULTS: Three-dimensional morphometric analysis revealed a significant (all P < 0.05) postoperative increase of the lip height-related measurements for cleft philtrum height, noncleft philtrum height, and central lip length parameters, with no difference ( P > 0.05) between cleft and noncleft sides. The postoperative three-dimensional projection of the philtral ridges was significantly ( P < 0.001) larger in cleft (1.01 ± 0.43 mm) than in noncleft sides (0.51 ± 0.42 mm). The average philtrum volume change was 1.01 ± 0.68 cm 3 , with an average percentage fat graft retention of 43.36% ± 11.35%. The panel assessment revealed significant ( P < 0.001) postoperative scar enhancement for the qualitative rating scale, with mean preoperative and postoperative scores of 6.69 ± 0.93 and 7.88 ± 1.14, respectively. CONCLUSION: Synchronous fat grafting and rigottomy improved philtrum length, projection, and volume and lip scar in patients with repaired unilateral cleft lip. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

Reconstruction of complex rectovaginal fistula is challenging, and it has a high recurrence rate. Traditional reconstruction included a local flap or a myocutaneous flap reconstruction, which is either difficult in radiated cases or that the flap is too thick for flap inset and requires multiple times of revision. Here we report successful rectovaginal fistula repair using a pedicled medial circumflex femoral artery perforator flap (MCFAP). A retrospective chart review was done to collect the information of this 63-year-old female patient who had rectovaginal fistula (RVF) resulting from concurrent radiochemotherapy for cervical cancer. She received direct repair of the RVF, but it recurred. We applied a pedicle perforator flap to successfully repair the defect. The fistula was repaired by separating the posterior vaginal wall from the anterior rectal wall. The anterior wall of the rectum was primarily repaired, leaving a defect of 4 × 5 cm in the posterior vaginal wall. A pedicled MCFAP flap was harvested from her right medial thigh and transferred via a subcutaneous tunnel for reconstruction of the posterior vaginal wall defect. The postoperative course was uneventful. Postoperative gastrointestinal series showed no more RVF, and her colostomy was taken down one year after the reconstruction. This first experience suggests that a pedicle perforator flap can be used successfully for reconstruction of a rectovaginal fistula.

RESUMO

Importance: Realizing the benefits of cancer screening requires testing of eligible individuals and processes to ensure follow-up of abnormal results. Objective: To test interventions to improve timely follow-up of overdue abnormal breast, cervical, colorectal, and lung cancer screening results. Design, Setting, and Participants: Pragmatic, cluster randomized clinical trial conducted at 44 primary care practices within 3 health networks in the US enrolling patients with at least 1 abnormal cancer screening test result not yet followed up between August 24, 2020, and December 13, 2021. Intervention: Automated algorithms developed using data from electronic health records (EHRs) recommended follow-up actions and times for abnormal screening results. Primary care practices were randomized in a 1:1:1:1 ratio to (1) usual care, (2) EHR reminders, (3) EHR reminders and outreach (a patient letter was sent at week 2 and a phone call at week 4), or (4) EHR reminders, outreach, and navigation (a patient letter was sent at week 2 and a navigator outreach phone call at week 4). Patients, physicians, and practices were unblinded to treatment assignment. Main Outcomes and Measures: The primary outcome was completion of recommended follow-up within 120 days of study enrollment. The secondary outcomes included completion of recommended follow-up within 240 days of enrollment and completion of recommended follow-up within 120 days and 240 days for specific cancer types and levels of risk. Results: Among 11 980 patients (median age, 60 years [IQR, 52-69 years]; 64.8% were women; 83.3% were White; and 15.4% were insured through Medicaid) with an abnormal cancer screening test result for colorectal cancer (8245 patients [69%]), cervical cancer (2596 patients [22%]), breast cancer (1005 patients [8%]), or lung cancer (134 patients [1%]) and abnormal test results categorized as low risk (6082 patients [51%]), medium risk (3712 patients [31%]), or high risk (2186 patients [18%]), the adjusted proportion who completed recommended follow-up within 120 days was 31.4% in the EHR reminders, outreach, and navigation group (n = 3455), 31.0% in the EHR reminders and outreach group (n = 2569), 22.7% in the EHR reminders group (n = 3254), and 22.9% in the usual care group (n = 2702) (adjusted absolute difference for comparison of EHR reminders, outreach, and navigation group vs usual care, 8.5% [95% CI, 4.8%-12.0%], P < .001). The secondary outcomes showed similar results for completion of recommended follow-up within 240 days and by subgroups for cancer type and level of risk for the abnormal screening result. Conclusions and Relevance: A multilevel primary care intervention that included EHR reminders and patient outreach with or without patient navigation improved timely follow-up of overdue abnormal cancer screening test results for breast, cervical, colorectal, and lung cancer.

RESUMO

Follicular neoplasms are classified as benign or malignant depending on the presence or absence of capsular and/or vascular invasion. Due to incomplete capsular penetration or equivocal vascular invasion, the evaluation of these features can be challenging using histologic examination. In the current study, we analyzed the involvement of G-protein coupled receptor-associated sorting protein 1 (GASP-1) in the development and progression of thyroid neoplasms. Affinity-purified anti-GASP-1 polyclonal antibodies were used for routine immunohistochemistry (IHC) analysis. Thyroid tissue microarrays containing normal thyroid tissue, follicular adenoma, follicular carcinoma, papillary thyroid carcinoma, and anaplastic carcinoma were analyzed. We found that the level of GASP-1 expression can differentiate follicular adenoma from follicular carcinoma. When numerous cases were scored for GASP-1 expression by a board-certified pathologist, we found that GASP-1 expression is 7-fold higher in thyroid malignant neoplasms compared to normal thyroid tissue, and about 4-fold higher in follicular carcinoma compared to follicular adenoma. In follicular adenoma tissues, we observed the presence of many mini-glands that are enriched in GASP-1 and some mini-glands contain as few as three cells. GASP-1 IHC also possesses several advantages over the conventional H&E and can be used to identify early thyroid cancer and monitor cancer progression.

RESUMO

BACKGROUND: Nasoalveolar molding (NAM) has become standard treatment in the authors' craniofacial center. There are two types of presurgical NAM: the Grayson and Figueroa techniques. The Grayson method involves active alveolar molding, and the Figueroa method involves passive alveolar molding. The authors previously found no differences in number of clinic visits, costs, or 6-month postoperative outcome between the two techniques. The authors extended the previous study to evaluate facial growth between these two groups. METHODS: In this randomized single-blind study, conducted between May of 2010 and March of 2013, the authors recruited 30 patients with unilateral complete cleft lip and palate and randomized them for Grayson or Figueroa presurgical NAM. Standard lateral cephalometric measurements at 5 years were used to determine facial growth. RESULTS: Twenty-nine patients completed 5 years of follow-up. There were no statistically significant differences in facial cephalometric measurements between the two groups. CONCLUSION: Presurgical NAM using either a passive or active NAM technique produced similar facial growth patterns after unilateral cleft lip and palate repair. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

RESUMO

Vascularized lymph node transplantation (VLNT) has shown inspiring results for the treatment of lymphedema. Nevertheless, it remains unclear how VLNT restores lymphatic drainage and whether or not immunity recovers after surgery. Hindlimb lymphedema model was created using rats with extensive groin and popliteal lymph node removable following with radiotherapy, and the lymphedema was confirmed using indocyanine green (ICG) lymphangiography and micro-computer tomography for volume measurement. VLNT was performed 1 month later. Volume measurement, ICG lymphangiography, histology, and immune reaction were done 1 month after surgery. VLNT successfully reduced the volume of the lymphedema hindlimb, restored lymphatic drainage function with proven lymphatic channel, and reduced lymphedema-related inflammation and fibrosis. It promotes lymphangiogenesis shown from ICG lymphangiography, histology, and enhanced lymphangiogenesis gene expression. Dendritic cell trafficking via the regenerated lymphatic channels was successfully restored, and maintained systemic immune response was proved using dinitrofluorobenzene sensitization and challenge. VLNT effectively reduces lymphedema and promotes lymphatic regeneration in the capillary lymphatic but not the collecting lymphatic vessels. Along with the re-established lymphatic system was the restoration of immune function locally and systemically. This correlated to clinical experience regarding the reduction of swelling and infection episodes after VLNT in lymphedema patients.

RESUMO

OBJECTIVE: There is a lack of research on adverse event (AE) detection in oncology patients, despite the propensity for iatrogenic harm. Two common methods include voluntary safety reporting (VSR) and chart review tools, such as the Institute for Healthcare Improvement's Global Trigger Tool (GTT). Our objective was to compare frequency and type of AEs detected by a modified GTT compared with VSR for identifying AEs in oncology patients in a larger clinical trial. METHODS: Patients across 6 oncology units (from July 1, 2013, through May 29, 2015) were randomly selected. Retrospective chart reviews were conducted by a team of nurses and physicians to identify AEs using the GTT. The VSR system was queried by the department of quality and safety of the hospital. Adverse event frequencies, type, and harm code for both methods were compared. RESULTS: The modified GTT detected 0.90 AEs per patient (79 AEs in 88 patients; 95% [0.71-1.12] AEs per patient) that were predominantly medication AEs (53/79); more than half of the AEs caused harm to the patients (41/79, 52%), but only one quarter were preventable (21/79; 27%). The VSR detected 0.24 AEs per patient (21 AEs in 88 patients; 95% [0.15-0.37] AEs per patient), a large plurality of which were medication/intravenous related (8/21); more than half did not cause harm (70%). Only 2% of the AEs (2/100) were detected by both methods. CONCLUSIONS: Neither the modified GTT nor the VSR system alone is sufficient for detecting AEs in oncology patient populations. Further studies exploring methods such as automated AE detection from electronic health records and leveraging patient-reported AEs are needed.

RESUMO

We have identified the novel protein GASP-1 (G protein coupled receptor-associated sorting protein 1) that appears to be a universal cancer marker and the expression of which in tumor tissue and patient sera is predictive of cancer severity (Tuszynski et al. 2011; Zheng et al. 2012; Zheng 2013; Chang and Tuszynski, 2020). In preliminary results we discovered that a GASP-1 antibody inhibited the growth of the triple negative breast cancer cell line MDA-MB-231 and transient reduction of GASP-1 in these cells decreased their proliferation. To further substantiate these results, we over and under-expressed GASP-1 in stable clones of MDA-MB-231 cells and evaluated their growth and invasive activities. Cells under-expressing GASP-1 failed to grow after 4 days in culture and eventually died. In contrast GASP-1 expressing cells grew exponentially. Similarly, GASP-1 under-expressing cells formed 30% fewer colonies in soft agar as compared to controls and whereas GASP-1 over-expressing cells formed 2-fold more colonies than controls. In tumor cell invasion assays GASP-1 over-expressing cells were over 10-fold more invasive than controls whereas GASP-1 under-expressing cells were over 10-fold less invasive than controls. In IHC staining studies of breast cancer cells, we found that the overexpressed GASP-1 appear in granules of different sizes that are directly correlated with cancer invasiveness. Our results strongly indicate that GASP-1 promotes proliferation and invasion of the triple negative breast cancer cell line MDA-MB-231 and targeting GASP-1 for treatment of breast cancer is indicated.

RESUMO

BACKGROUND AND OBJECTIVES: Postoperative short nose is one of the most difficult problems encountered in plastic surgery. We propose a technique of lining rotation flaps combined with composite chondrocutaneous auricular graft from the triangular fossa to reconstruct the lining defect and improve surgical results. METHODS: Twenty patients were operated on between 2016 and 2019 for postoperative short nose. Lining rotation flaps were used to supply missing medial mucosal lining with creation of a raw surface at the lateral lining in 10 patients (intervention group). A total of 17 composite chondrocutaneous grafts taken from the triangular fossa of the ears were used to resurface the defect. The other 10 patients received lining management using conventional techniques (control group). RESULTS: There was a near-complete take of 13/17 composite grafts (76.5%), with four partial losses that healed uneventfully. Anthropometric analysis of preop and postop profile photos showed statistically significant decreased nasolabial angle in both groups. The amount of derotation achieved was significantly increased (p < 0.05) with our proposed method (Intervention group: 12.3 ± 9.3° vs. control group: 6.55 ± 4.5°). Donor sites healed uneventfully. Both groups of patients were satisfied with their results based on Rhinoplasty Outcomes Evaluation questionnaire. CONCLUSIONS: The lining rotation flap with triangular fossa composite graft is a safe and effective method for management of the postoperative short nose in Asians.

RESUMO

BACKGROUND: Gynecological reconstruction is difficult, particularly in cases with recurrence and received previous surgeries and/or radiotherapy and necessitate secondary reconstruction. Perforator flaps can preserve other donor sites for potential later reconstruction, and they also can be better tailored to the defect. We hypothesized that the use of perforator-based flaps can better restore the defect with less complications. METHODS: A retrospective review was conducted of all patients who underwent vulvar-perineum reconstruction between 2011 and 2018 by the senior author, and oncologic and reconstructive outcomes and complications were analyzed. RESULTS: Thirty-three patients underwent 55 soft tissue reconstructions for vulvar-perineum defects during the study period. The mean follow-up time was 27.6 ± 28.9 months. Squamous cell carcinoma was the most common cancer (45.5%). For 11 patients (33.3%), the procedures were performed for the treatment of recurrent cancer. The average defect size was 39.8 ± 34.3 cm2. The overall survival rate was 90.3%. Profunda artery perforator flaps were the most commonly applied flap for reconstruction in both the primary and recurrent groups. Poor wound healing was the most common complication which occurred in 10 of the 55 flaps (18.2%). Perforator flaps presented fewer complications than myocutaneous flaps or traditional random flaps. Similarly, Island pedicle flap design also presented fewer complications than traditional rotation flaps. With proper reconstruction, previous surgery or radiotherapy did not contribute to an increase in complications. CONCLUSION: In our experience, perforator flaps can provide satisfactory reconstruction for perineum reconstruction with low postoperative complications while preserving other donor sites in the event of disease recurrence for repeat resection and reconstruction. Previous surgery or radiotherapy did not increase the complications or preclude its usage. A redefined reconstructive ladder was created to help selecting the best state-of-the-art technique for reconstruction to achieve better results.

RESUMO

INTRODUCTION: The medical demand for lymphedema treatment is huge since the disease mechanism remains unclear, and management are difficult. Our purpose was to develop a reliable lymphedema model mimicking the clinical scenario and allows a microsurgical approach. MATERIALS AND METHODS: Male Lewis rats weighing 400 to 450 g were used to create lymphedema with groin and popliteal lymph node dissection and creation of 5 mm circumferential skin defect (n = 6). A skin incision was made and closed primarily for control group (n = 5). Evaluation included indocyanine green (ICG) lymphangiography 1 and 2 months postoperatively, volume difference between bilateral hindlimbs measured using micro-CT, and the skin was harvested for histological evaluation 2 months postoperatively. RESULTS: Larger volume differences present in the lymphedema group (17.50 ± 7.76 vs. 3.73 ± 2.66%, p < .05). ICG lymphangiography indicated dermal backflow only in the lymphedema group. Increased thickness of the epidermis was noted in lymphedema group (28.50 ± 12.61 µm vs. 15.10 ± 5.41 µm, p < .0001). More CD45+ (35.6 ± 26.68 vs. 2.8 ± 4.23 cells/high power field [HPF], p < .0001), CD3+ (38.39 ± 20.17 vs. 9.73 ± 8.62 cells/HPF, p < .0001), and CD4+ cell infiltration (11.7 ± 7.71 vs. 2.0 ± 2.67 cells/HPF, p < .0001) were observed in the lymphedema group. Collagen type I deposition was more in the lymphedema group (0.15 ± 0.06 vs. 0.07 ± 0.03, p < .0005). CONCLUSIONS: A rat lymphedema model was successfully established. The model can be applied in lymphedema related research.

RESUMO

BACKGROUND: The application of robotic-assisted nipple-sparing mastectomy (R-NSM) has allowed mastectomy to be performed via a small incision. Breast reconstruction with free autologous tissue results in the most natural and long-lasting results, however, its application in R-NSM can be difficult via the small incision and haven't been explored in depth. The purpose of the study was to investigate the feasibility and aesthetic outcome of free perforator flap breast reconstruction via small lateral chest wall incision after R-NSM. MATERIALS AND METHODS: A retrospective chart review was conducted to identify patients who received R-NSM and free perforator flap reconstruction as the study group and patients who received conventional nipple-sparing mastectomy (C-NSM) and free perforator flap reconstruction as the control group from January 2018 to August 2020 by single reconstructive surgeon. Patient demographic data, complications from both mastectomy and reconstruction, status of resection margin and oncological outcome were reviewed. Aesthetic outcome was evaluated by 9 plastic surgeons. RESULTS: A total of 63 patients were included of which 22 (34.9%) received R-NSM and 41 (65.1%) received C-NSM. Their demographic data, reconstruction flaps, overall complication rate and follow up time were similar. Unlike C-NSM, majority of the R-NSM groups used the thoracodorsal or lateral thoracic vessels as the recipient vessels. Patients in the R-NSM group has smaller scar and better aesthetic outcome in the symmetry of breast inframammary fold, scar location and visibility, and overall aesthetic outcome. CONCLUSION: Although with difficulty in microvascular anastomosis and flap inset and shaping, R-NSM with perforator flap reconstruction presented with equal surgical and oncological safety with C-NSM and even better aesthetic results.

RESUMO

Granular cell tumour (GCT) is a rare soft tissue lesion which many consider to have malignant potential of yet unknown aetiopathogenesis. Oral GCT lesions may occur in an area of leucoplakia and are predominantly present on the tongue. This case study highlights an uncommon presentation of this condition located on the buccal mucosa and illustrates the need for meticulous evaluation of suspicious lesions. Due to the malignant risk associated with GCT lesions, it is important to make the correct diagnosis and ensure complete surgical excision for these cases. Ongoing long-term follow-up is also indicated to monitor for recurrence or malignancy.

RESUMO

INTRODUCTION: While substantial attention is focused on the delivery of routine preventive cancer screening, less attention has been paid to systematically ensuring that there is timely follow-up of abnormal screening test results. Barriers to completion of timely follow-up occur at the patient, provider, care team and system levels. METHODS: In this pragmatic cluster randomized controlled trial, primary care sites in three networks are randomized to one of four arms: (1) standard care, (2) "visit-based" reminders that appear in a patient's electronic health record (EHR) when it is accessed by either patient or providers (3) visit based reminders with population health outreach, and (4) visit based reminders, population health outreach, and patient navigation with systematic screening and referral to address social barriers to care. Eligible patients in participating practices are those overdue for follow-up of an abnormal results on breast, cervical, colorectal and lung cancer screening tests. RESULTS: The primary outcome is whether an individual receives follow-up, specific to the organ type and screening abnormality, within 120 days of becoming eligible for the trial. Secondary outcomes assess the effect of intervention components on the patient and provider experience of obtaining follow-up care and the delivery of the intervention components. CONCLUSIONS: This trial will provide evidence for the role of a multilevel intervention on improving the follow-up of abnormal cancer screening test results. We will also specifically assess the relative impact of the components of the intervention, compared to standard care. TRIAL REGISTRATION: ClinicalTrials.gov NCT03979495.

RESUMO

BACKGROUND: Lower blepharoplasty is a common cosmetic operation that relies on minimal postoperative scarring, but Asian patients are at higher risk than Caucasians for hypertrophic and/or widened scars. Botulinum toxin type A (BTX) injections are widely employed to alleviate dynamic facial rhytids and also can improve scar quality by reducing scar tension. The authors assessed whether simultaneous transcutaneous lower blepharoplasty and BTX injections could improve subciliary scar quality. OBJECTIVES: The objective of this study was to assess whether simultaneous transcutaneous lower blepharoplasty and BTX injections could improve subciliary scar quality. METHODS: This is a prospective, randomized, vehicle-controlled, double-blinded clinical trial. Between May 2015 and May 2018, 40 adults who underwent bilateral transcutaneous lower blepharoplasties were randomized to receive BTX (n = 20) or vehicle (normal saline; n = 20) injections into the lateral orbicularis oculi muscle immediately after wound closure. Vancouver Scar Scale, Visual Analogue Scale, and photographic scar width measurements at 3 reference points were recorded at the final clinical follow-up. RESULTS: Thirty-seven patients completed the trial. Vancouver Scar Scale and Visual Analogue Scale scores in the experimental and vehicle control groups were similar, but scar widths in the experimental group at all measured points were significantly narrower than in the vehicle control group (P < 0.001, P = 0.027, and P < 0.001 at each measured point, respectively). CONCLUSIONS: Transcutaneous lower blepharoplasty scars in Asians can be significantly narrowed by simultaneous BTX injections without additional complications.

RESUMO

BACKGROUND: The main objective of contemporary orthognathic surgery is to correct dentofacial deformities. Nonetheless, many adjunct procedures to enhance the esthetic outcome in orthognathic surgical cases have been successfully incorporated to improve patient satisfaction. The authors report our preliminary experience of performing simultaneous orthognathic surgery with Asian double eyelid suture method blepharoplasty in the same surgical setting. METHOD: This case series report includes all 19 consecutive cases presenting to the Chang Gung Craniofacial Center for combined orthognathic surgery with Asian double eyelid suture method blepharoplasty. The double eyelid crease height was measured as the vertical line between the upper eyelid margin (eyelid lash) and the upper eyelid crease, observed at the mid-pupillary line with the eyes in primary gaze. RESULTS: There were no complications or relapse reported within this time period. There was significant improvement in the left and right mid-pupillary double eyelid crease height postsurgery. There were no statistically significant differences between the left and right mid-pupillary double eyelid crease heights after surgery indicating good eyelid crease height symmetry bilaterally was obtained. CONCLUSIONS: Orthognathic surgery combined with suture method blepharoplasty can be safely performed in the same surgical setting without inappropriate rise in costs or operating room time. This case series demonstrates that excellent esthetic results can be obtained in simultaneous bimaxillary orthognathic surgery with suture method Asian blepharoplasty.
