Objective:To evaluate the effectiveness of surgical methods for correcting pollybeak deformity in Chinese rhinoplasty.Methods:A retrospective chart review was conducted for patients who underwent pollybeak correction between January 2021 and December 2022 at the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University. Individualized correction was tailored based on the etiology and severity of the nasal deformity of each patient, involving techniques such as resection of the anterior part of the nasal septum, reconstruction of nasal tip support, reconstruction of the middle part of the nasal vault, and excision of skin in the upper region of the nasal tip. A modified classification system for pollybeak deformity, the supratip fullness rating scale (SFRS), was developed to evaluate supratip fullness (0-3 points, with higher scores indicating more apparent deformity). The patients aesthetic outcomes were assessed by surgeons using the visual analogue scale (VAS) (0-10 points, with higher scores indicating more apparent deformity), and patient self-assessed using the rhinoplasty outcome evaluation (ROE) questionnaire (0-100 points, with higher scores indicating higher satisfaction). The measurement data of normal distribution was expressed as Mean±SD and analyzed by paired t-test; the measurement data of non-normal distribution was expressed as M( Q1, Q3) and analyzed by Wilcoxon signed rank test. Results:In a cohort study of 53 rhinoplasty patients (7 male, 46 female; age range 19-45 years, mean 29 years), comprising 15 primary and 38 secondary surgeries, nasal tip deformities were evaluated. Deformities were classified as mild (5 cases), moderate (25 cases), and severe (23 cases). Over a follow-up period of 6-17 months (mean 9.5 months), significant aesthetic improvements in the nasal tip region were observed. The SFRS scores decreased from 2(2, 3) preoperatively to 0(0, 0) postoperatively ( Z = -6.58, P < 0.001), and VAS scores decreased from 7.47±1.73 to 1.79±1.67 ( t = -25.61, P < 0.001). High patient satisfaction was indicated by a mean ROE score of 82.45±11.55. No significant complications, such as nasal tip ptosis, skin necrosis, or scar hyperplasia, were reported. Conclusion:Selecting an appropriate surgical method based on the severity and cause of pollybeak deformity can achieve satisfactory outcomes. Post-operative patients exhibit significant aesthetic improvement in the upper nasal tip area, resulting in high patient satisfaction.

Objective:To explore the clinical efficacy of modified superomedial pedicle technique using an inverted T-shaped incision for reduction mammaplasty and mastopexy.Methods:A retrospective analysis was conducted on clinical data of patients who underwent modified superomedial pedicle technique for breast reduction surgery with inverted T-shaped incision between March 2021 and March 2023 at the Department of Plastic and Aesthetic (Burn) Surgery, Second Xiangya Hospital of Central South University. Preoperatively, a handheld Doppler ultrasound blood flow detector was used to detect and mark the exit points of the 2nd to 4th perforating vessels of the internal thoracic artery, and a superomedial pedicle containing at least two perforators was designed based on the perforator locations, with a pedicle width generally about 6 cm. Intraoperatively, the pedicle was rotated superolaterally, moving the nipple-areola complex (NAC) upwards to construct a fuller upper pole of the breast and removing excess skin in the lower fold to form a inverted T-shaped incision. Postoperatively, the blood supply of the NAC, breast morphology, and incidence of complications were observed and followed up. Canfield Mirror 7.1.1 software was utilized to measure pre- and post-operative breast morphology data from lateral photographs at 6 months, including total breast area, maximum breast protrusion, upper pole protrusion, lower pole height, and nipple elevation height. The BREAST-Q questionnaire was used to survey patient satisfaction with breast appearance, psychosocial well-being, sexual well-being, and physical health before surgery and 6-12 months after surgery, with each dimension scoring 0-100 points, where higher scores indicate greater satisfaction and health. SPSS 28.0 software was used for data analysis, with normally distributed measurement data expressed as Mean±SD, and paired t-test was applied for comparisons of pre- and post-operative breast morphology data (the first 4 indicators) and BREAST-Q scores, with P<0.05 considered statistically significant. Results:A total of 56 female patients were included, with an age of (32.0±6.7) years and a body mass index of (29.1±5.7) kg/m 2. Preoperative Doppler ultrasound blood flow detection showed that none of the patients had missing or significantly variant perforators of the superomedial pedicle. The volume of breast tissue removed ranged from 890 to 1 800 ml, averaging 1 250 ml, with an average pedicle width of 5.4 cm (4.0-7.0 cm). The follow-up period was (13.3±2.5) months, during which all patients exhibited good blood supply to the NAC and favorable breast morphology, with universal high satisfaction with surgical outcomes. Postoperatively, one case developed incisional seroma, which resolved naturally within 3 months; two cases experienced minor incision dehiscence, which healed well after dressing changes; all other patients recovered well without any complications such as flap necrosis or hematoma. Comparison of breast morphology data showed significant reductions in postoperative left and right total breast area ( P<0.05 for both), and increases in maximum breast protrusion and lower pole height postoperatively ( P<0.05 for both), while the difference in upper pole protrusion was not statistically significant ( P>0.05 for both); postoperative left and right nipple elevation heights were (6.30±1.84) cm and (6.52±1.66) cm, respectively. Among the 44 patients who completed the BREAST-Q survey both before and after surgery, scores showed significant improvements in postoperative breast satisfaction [(50.30±10.30) points vs. (83.20±6.02) points] ( t=5.17, P=0.008) and psychosocial well-being [(56.20±17.20) points vs. (89.70±2.70) points] ( t=5.09, P=0.010), while sexual well-being and physical health scores did not differ significantly from preoperative scores ( P>0.05 for both). Conclusion:Preoperative identification of perforator locations using a handheld Doppler blood vessel detector, followed by the design of a modified superomedial pedicle technique for reduction mammaplasty with inverted T-shaped incision, can not only ensure NAC blood supply, avoiding ischemic necrosis due to vascular anomalies, but also maximally reduce pedicle width and increase pedicle rotation flexibility, achieving desirable breast shaping effects.

The patient was a 29-year-old male with a history of hemophilia for more than 10 years. After 6 hours of botulinum toxin injection into the masseter muscle, the redness and swelling of the right face gradually worsened, accompanied by local pain, and restricted mouth opening, etc. The hematoma was absorbed and the swelling subsided significantly after the infusion of coagulation factor Ⅸ. Such cases of large-scale hematomas after botulinum toxin injection in hemophiliacs is rarely reported. This article summarized the diagnosis and treatment process of this case and combines with literature review to provide clinical experience for diagnosis, treatment and prevention of similar complications.

Objective:To investigate the application effects of a novel framework: the external septal retention bionic framework in East Asian rhinoplasty.Methods:A retrospective analysis was performed based on the clinical data of the patients who received treatments in Department of Plastic and Aesthetic ( Burn) Surgery, the Second Xiangya Hospital, Central South University from January 2022 to July 2023 using an external septal retention bionic framework with autologous costal cartilage rhinoplasty. The patients were all treated with a V-shaped incision at the nasal columella, which continued to both sides of the nose to form a bird-shaped incision. During the operation, the sixth or seventh costal cartilage was sculpted to form the nasal columella support grafts (sturt), external nasal septal graft, cap grafts, and shield grafts, in which the nasal column support graft and external nasal septal graft were implanted in a mortise-and-tenon joint structure to form a septum bionic retained external stent in order to lengthen the nasal columellar column and strengthen the septum. A capsular graft was used to shape the tip of the nose and the rectus abdominis fascia was covered to soften the tip of the nose, and the shield grafts were used to fill out the subnasal lobules. A bulb was sculpted, shaped and implanted in the dorsal space to elevate the nasal dorsum. To observe the postoperative results and complications, a postoperative satisfaction survey was completed using the rhinoplasty outcome evaluation (ROE) and the visual analogue scale (VAS) with regular follow-up. Comparison of preoperative and postoperative scale scores was performed using paired samples t-test. Nasal stent stability was assessed by measuring the patients’ preoperative and postoperative nasolabial angle and nasal tip protrusion. The comparison of preoperative and postoperative nasolabial angle was performed using the paired-sample t-test, and the comparison of nasal tip protrusion was performed using the Wilcoxon signed rank-sum test, P<0.05 considered a statistically significant difference. Results:A total of 33 patients were enrolled, including 4 males and 29 females, with average age of 23.8 years(15-42 years). The follow-up period is (14.52 ± 4.72) months (3 to 21 months). Thirty-three patients recovered well after surgery, and no short-term complications such as infection or bleeding occurred. The patients' nasal aesthetic problems such as saddle nose, deviated nasal columella, bilateral asymmetry of the nose, bilateral nasal base depression, and rounded shield of the nasal tip were improved after surgery. Satisfaction survey results: ROE and VAS scores were significantly higher than those before surgery, which were [(17.92±2.56) vs.(12.78±3.14)] and [(8.08±1.66)vs(5.15±1.99)], ( P<0.05), 87.9% (27/33)of the patients were satisfied with the aesthetic and functional outcomes of the nose. Comparisons of nasolabial angle [(87.28±2.58)° vs. (97.64±1.95)°] and tip protrusion [1.88 (1.78, 1.95) cm vs. 2.16(2.01, 2.32) cm] measurements between preoperative and postoperative period of the 33 patients, the differences were statistically significant ( P<0.05). Conclusion:Rhinoplasty for East Asians employs an external septal retention bionic framework to retain the nasal septum. This technique can avoid septal cartilage resorption caused by compression of grafts transplanted in the future, and cause less damage to the anatomy and physiology of the nose. The framework is relatively easy to construct, with a stable and strong stent, and good patient satisfaction. It can achieve a more desirable aesthetic effect of the nose.

Objective:To investigate the complications and related etiologies after immediate silicone implant and immediate two-stage tissue expander/implant breast reconstruction.Methods:A retrospective study was conducted in 23 patients who underwent implant or tissue expander/implant breast reconstruction surgery from June 2016 to October 2019. The etiology, medical history and clinical symptoms of each patient were analyzed and related treatments were carried out depending on its complication.Results:All patients were followed up for 3-12 months after surgery. Among the 23 patients, a total of 8 patients had different types of postoperative complications. Partial necrosis of the nipple-areola complex occurred in 1 case, postoperative infection in 2 cases, 2 patients experienced deviation of the implant or tissue expander and displacement of the nipple-areola complex in 3 cases. All complications were treated accordingly, and a good therapeutic effect was finally maintained.Conclusions:For patients with complications after immediate silicone implant and two-stage tissue expander/implant breast reconstruction, treatment should be carried out according to the causes of complications in time. In this way, patient can get better prognosis.

Objective:To evaluate the structural features, stability and postoperative effect of integrated framework, 1+ 1 framework, 2+ 1 framework, 4+ 1 framework, and Y-shaped nasal framework.Methods:A retrospective analysis was performed based on the clinical data of patients underwent in Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital, Central South University from February 2019 to November 2020. According to rhinoplasty framework, the patients were divided into integrated framework group, 1+ 1 framework group, 2+ 1 framework group, 4+ 1 framework group, and Y-shaped framework group. Based on the principle of plane photography, the stability of the nasal framework was evaluated by measuring the nasal tip projection and the nasolabial angle 1 month after surgery, and 12 months after surgery. The satisfaction of patients and the incidence of postoperative complications were collected. The difference in nasolabial angle and nasal tip projection data of postoperation 1 month and postoperative 12 months among each group were analyzed by one-way analysis vaniance or Kruskal-Waliis H test.Bonferroni test or Nemenyi test was used for pairwise comparison between groups. P< 0.05 was considered statistically significant. Results:A total of 201 patients (18 males and 183 females, aged 18-46 years, average aged 26.6±5.9 years)were included in this study and followed up for 12-21 months.

The difference of nasal tip projection among the five groups was statistically significant ( P<0.01). The difference between 2+ 1 framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant( P<0.05). The difference between 4+ 1 framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant ( P<0.05). The difference between integrated nasal framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant ( P<0.05). The difference between Y-shaped framework group and 1+ 1 framework group was statistically significant ( P<0.05). In terms of nasolabial angle during postoperative follow-up, the median difference of nasolabial angle between 12 months and 1 month after surgery in 2+ 1 framework group, integrated framework group, 1+ 1 framework group, and 4+ 1 framework group, and Y-shaped framework group was -4.20°, -3.80°, -6.50°, -4.10° and -6.35°, respectively. The difference of nasolabial angle among the five groups was statistically significant ( P<0.01). The difference between 2+ 1 framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant( P<0.05). The difference between 4+ 1 framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant ( P<0.05). The difference between integrated nasal framework group and 1+ 1 framework group or Y-shaped framework group was statistically significant ( P<0.05). Patient satisfaction evaluation, 2+ 1 framework group had the highest satisfaction(34/34, 100.00%), followed by 4+ 1 framework group (34/35, 97.14%), integrated framework group(42/45, 93.33%), Y-shaped framework group(36/42, 85.71%), 1+ 1 framework group(37/45, 82.22%). Conclusion:The changes of nasolabial angle and nasal tip projection in 2+ 1 framework, integrated framework, and 4+ 1 framework were smaller than those in Y-shaped framework and 1+ 1 framework.2+ 1 framework was convenient and had good postoperative stability and high patient satisfaction.
