RESUMO
Objective:To investigate the effect of ship-shaped expanded polytetrafluoroethylene (e-PTFE) nasal prosthesis in rhinoplasty.Methods:From February 2016 to June 2021, 86 patients, including 9 males and 77 females, aged 18-47 (24±5) years old, were admitted to Chengdu High-tech Zone Xinyuerong Medical Aesthetic Clinic for cosmetic treatment of rhinoplasty. All patients underwent rhinoplasty with the application of ship-shaped e-PTFE and autologous cartilage. The postoperative complications, glabellar fullness, inverted brow triangle, nasal polygon aesthetic shape and patient satisfaction were evaluated. These data were measured and analyzed, including the nasal length, nasal tip height, nasal frontal angle and nasal facial angle before and after the operation.Results:In 86 patients, the incision healed in one stage after surgery, and 8 cases had nasal vestibular scar hyperplasia. All patients were followed up for 1-5 years: 84 cases obtained satisfactory nasal morphology, and 2 cases recovered naturally after adjusting and lowering the prosthesis height half a year after surgery because the interbrow area was too full. 74 patients (86%) were very satisfied, 10 cases (11.6%) were satisfied. The nasal length was (4.07±0.20) cm, the nasal tip height was (2.66±0.36) cm, the nasal frontal angle was (106.42±8.04)°, and the nasal face angle was (15.90±0.85)°before operation. The nasal length was (4.23±0.20) cm, the nasal tip height was (2.59±0.26) cm, the naso-frontal angle was (113.69±6.34)°, and the naso-facial angle was (21.57±0.78)° at eighteen months after operation. There were statistically significant differences in nasal length, naso-frontal angle and naso-facial angle ( t=-5.51, -5.96, -52.31, P<0.01), but no statistically significant differences in nasal tip height ( t=1.47, P=0.146). Conclusions:The ship-shaped e-PTFE can be shaped to reflect the aesthetic of the nose dorsum, which is similar to the anatomical structure of the nose dorsum, increase the stability and authenticity of the prosthesis, and is worthy of clinical application.
RESUMO
Objective:To explore the feasibility and advantages of integrated prosthesis of expanded polytetra-fluoroethylene (e-PTFE) in eyebrow arch augmentation.Methods:The clinical data of 45 patients with low or flat brow arch and glabellar zone from June 2019 to October 2020 in Chengdu High-tech Zone Xinyuerong Medical Aesthetic Clinic were analyzed retrospectively, in which it included 45 women, whose ages ranged from 20 to 39 years with average 29.8 years. Forty-three cases underwent primary surgery, and 2 cases underwent repair. The e-PTFE was sculpted to be personalized integrated prosthesis according to the shape of the patient's eyebrow arch and glabellar zone. The incision was designed on the medial and lateral sides of the lower margin of the bilateral eyebrow to avoid the supraorbital foramen, and the lacunae were striped under the frontal periosteum, and the two sides were connected to cover the glabellar zone and inverted triangle area between the eyebrows. The carved e-PTFE was implanted into one side and pulled out from the other side. The prosthesis was smoothed by Venn pliers of the ventral and dorsal sides.Results:The 45 patients in this group were followed up for 6-18 months. The incisions of all the patients were healed Ⅰ/A, and the scar of the incisions was concealed. Slight scalp numbness occurred in 4 patients and returned to normal 3 months later. The prosthesis in the glabellar zone appeared in 1 case 3 months after operation and returned to normal after reoperation. The symmetry, radian, fullness, convexity and tactility of bilateral eyebrow arch were all satisfactory in 45 cases. 39 cases were very satisfied, accounting for 86.7%; 6 cases (13.3%) were satisfactory. The sagittal distance of the anterior surface of the cornea to the soft tissues overlying the supraorbital rims was (2.02±1.72) mm preoperatively and (6.5±1.19) mm in the last follow-up. The difference was statistically significant ( t=14.49, P<0.01). Conclusions:This design of integral e-PTFE in eyebrow arch augmentation is safe, effective and easy to operate. It can significantly increase the bony beauty and stereoscopic sense of the eyebrow arch and glabellar zone, effectively deepen the eye socket, improve the eye protrusion, and reduce the risk of asymmetry and prosthesis displacement, and therefore it is one of the ideal methods for eyebrow arch augmentation.
RESUMO
Objective:To investigate the clinical effectiveness and significance of special fixing cartilaginous support structure on nasal tip to prevent and correct alar rim retraction.Methods:Special shaped tip extension support structure was composed of two parts of type Ⅲ of septum extension graft (SEG) and two pieces of wedge graft fixed on either side of the cephalic end near the top of support structure. After the alar cartilage vault was fixed to the nasal tip cartilage support structure, the lower lateral cartilage (LLC) cephalic was fixed to both sides of this nasal tip support structure. The LLC received support from the cartilaginous support structure to counter and correct the lower lateral cartilage cephalic retraction. From January 2017 to January 2020, this surgical procedure was used in 34 patients (aged from 20 to 46 years, with mean 32.6 years) with rhinoplasty who had a nasal tip support structure but still had a space between the LLC and the stent intraoperativly. Preoperativly, 4 cases had normal relation of alar columella and alar rim, 18 cases had mild alar rim retraction, and 12 cases had moderate alar rim retraction. The patients were followed up for 6 to 18 months to observe the correction effect and patient satisfaction.Results:Among the 34 patients, 8 patients received alar edge graft, 2 patients received lateral foot support graft, and 2 patients received alar rim graft combined with lateral foot support graft. All patients were followed up for 6-18 months, 30 patients with alar rim retraction were completely corrected, and 4 patients with normal alar and nasal columella relationship did not have alar rim retraction after surgery. No complications such as infection, necrosis, contracture or respiratory dysfunction were found in all patients. 28 cases (82.4%) were very satisfied; 6 cases (17.6%) were satisfied; the satisfactory rate was 100%.Conclusions:The special shaped nasal tip cartilage support structure combined with type Ⅲ SEG and its cephalic wedge grafts could achieve satisfactory clinical results in the prevention and correction of alar rim retraction.
RESUMO
Objective:To investigate the effectiveness of a modified upper lip lifting technique with retaining the nasal columellar base incision.Methods:From Jun. 2019 to Jun. 2020, 24 cosmetic patients (aged from 18 to 36 years, with mean 26.5 years) underwent upper lip lifting with skin flap resection of bilateral upper lip flaps and retained the nasal columellar base in Chengdu High-Tech Zone Xinyuerong Medical Aesthetic Clinic. These factors were analyzed, including postoperative complications, improvement of nasolabial angle, effectiveness of upper lip lifting and overall satisfaction.Results:In the 24 patients, 2 patients had numbness in the upper lip after surgery, and returned to normal after 4 months. The concealed scar was effective to improve the linear scar and scar contracture of traditional upper lip lifting. All patients were followed up for 3 months to 1 year. The satisfactory lifting effectiveness was obtained in 24 cases. As for overall satisfaction, 22 cases were very satisfied (91.7%) and 2 cases were satisfied (8.3%).Conclusions:This upper lip lifting surgical procedure of upper lip flaps with retaining the nasal columellar base incision has changed the traditional method to avoid the upper lip horizontal line scar, nasolabial angle contracture, while ensuring the columellar base blood supply is not damaged, with minimized and concealed scar. This surgical procedure is a safe and effective method and worth clinical application.
RESUMO
BACKGROUND@#Previously, we developed a novel Coronary Artery Tree description and Lesion EvaluaTion (CatLet©) angiographic scoring system, which was capable of accounting for the variability in the coronary anatomy and assisting in the risk-stratification of patients with acute myocardial infarction (AMI). Our preliminary study revealed that the CatLet score better predicted clinical outcomes for AMI patients than the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score. However, the reproducibility of the CatLet score in both inter- and intra-observer remains to be evaluated.@*METHODS@#A total of 30 consecutive AMI patients, admitted in September of 2015, were independently assessed by two experienced interventional cardiologists to evaluate the inter-observer reproducibility of the CatLet score. Another set of 49 consecutive AMI patients, admitted between September and October in 2014, were assessed by one of the two interventional cardiologists on two occasions 3 months apart to evaluate the intra-observer reproducibility of the CatLet score. The weighted kappa was used to express the degree of agreement.@*RESULTS@#The weighted kappa values (95% confidence interval) for the intra- and inter-observer reproducibility of the CatLet Score were 0.82 (0.59-1.00, Z = 7.23, P 22). Regarding the adverse characteristics pertinent to lesions and dominance parameters, the kappa values for the inter-observer variability were 0.80 (0.56-1.00, Z = 6.47, P < 0.001) for total number of lesions, 0.57 (0.28-0.85, Z = 3.03, P < 0.001) for bifurcation, 0.69 (0.43-0.96, Z = 5.06, P < 0.001) for heavy calcification, 1.00 (0.72-1.00, Z = 6.93, P < 0.001) for tortuosity, 0.54 (0.26-0.82, Z = 3.78, P < 0.001) for thrombus, 0.69 (0.48-0.91, Z = 6.29, P < 0.001) for right coronary artery dominance, 0.69 (0.41-0.96, Z = 4.91, P < 0.001) for left anterior descending artery length, and 0.22 (0.06-0.51, Z = 1.56, P = 0.06) for diagonal size. Equivalent values for the intra-observer variability were moderate to almost perfect (range 0.54-1.00).@*CONCLUSIONS@#The reproducibility of the CatLet angiographic scoring system for evaluation of the coronary angiograms ranged from substantial to excellent. The high reproducibility of the CatLet angiographic scoring system will boost its clinical application to patients with AMI.

Objective To investigate the relationship between tumor necrosis factor α (TNF-α) rs1800629 polymorphisms and cervical cancer risk. Methods A case-control study was carried out including 552 patients with cervical cancer and 654 normal controls during the same period. TNF-α rs1800629 polymorphisms were examined by Taqman-Probe assay method. The association between the genotypes and cervical cancer was analyzed by Logistic regression models. Stata 11.0 was used for the Meta-analysis. Results Compared with the TNF-α rs1800629 GG genotype, individuals with GA, AA and GA/AA genotypes showed no significant changes in the risk of cervical cancer (all P>0.05). Further Meta-analysis on the relationship between the polymorphisms of TNF-α rs1800629 and cervical cancer also suggested that there was no significant correlation between the genetic variation and the occurrence of cervical cancer. Conclusion The polymorphisms of TNF-α rs1800629 may not be related to cervical cancer risk in Chinese population.
