Objective:To investigate the clinical efficacy and safety of ultrasonic bone scalpel in nasal osteotomy.Methods:A retrospective analysis was conducted on clinical data from the patients who received ultrasonic bone scalpel-assisted nasal osteotomy in the Nasal Plastic & Reconstructive Surgery Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2023 and April 2024. All patients underwent open lateral approach osteotomy using an ultrasonic bone scalpel under direct vision, combined with augmentation rhinoplasty using autologous costal cartilage grafting. Intraoperatively, the nasal dorsum was fully exposed, and the lateral nasal cartilage was separated from the nasal septum, followed by precise bone tissue incision using the ultrasonic bone scalpel. Parameters recorded included operative time, and postoperative complications. Based on the standardized photographs taken before the operation and during the 6-month follow-up after the operation, the observer global aesthetic improvement scale (GAIS) was evaluated by a third-party doctor, with a score ranging from 1 to 5. The smaller the score, the more significant the improvement compared to before the operation. The satisfaction of patients with the surgical outcome was evaluated and classified into four levels: very satisfied, satisfied, dissatisfied, and very dissatisfied.Results:A total of 25 female patients were enrolled, aged 20 to 38 years, with an average age of 27.1 years. All procedures were completed successfully, with a mean operative time of (25.4±4.2) minutes. Postoperative localized swelling of varying degrees was observed. Follow-up ranged from 6 to 18 months, with nasal contour and curvature stabilizing by 6 months postoperatively. No complications, such as infection, nasolacrimal duct, lacrimal sac, medial canthal ligament, nerve injuries, or sensory disturbances, were reported. Two cases exhibited mild nasal bone widening at the 6-month follow-up, though no surgical revision was requested. Significant improvement in external nasal morphology was achieved in all patients, with high satisfaction rates. The patients satisfaction survey showed that 18 cases (72%) were very satisfied and 7 cases (28%) were satisfied with the surgical outcome. GAIS scores reflected positive evaluations [(1.24±0.51) points].Conclusion:The ultrasonic bone scalpel for nasal osteotomy offers the advantages of high-precision cutting and efficient hemostasis. It is highly effective in reshaping the nasal contour, with shorter osteotomy time, reduced intraoperative bleeding, and a lower postoperative complication rate. This study provides some insights into plastic surgeons in optimizing nasal bone modification strategies.

Objective:To investigate the clinical effect of jujube core-shaped tissue resection technique in the treatment of alar reduction.Methods:A retrospective analysis was performed for the clinical data of patients who underwent alar reduction from February 2019 to June 2022. A spindle-shaped incision line was designed along the outer edge of the base of the nasal lobule, with a width of 4-5 mm and a length of 8-12 mm. The incision line was 1-2 mm away from the alar groove, and the inner side of the design line was extended to the inside of the nasal vestibule. After the incision was made, the subcutaneous tissue was undermining dissected with curved sharp scissors, and the shape of the extended excision tissue was similar to that of jujube core. After reduction, the incision was closed with vertical mattress suture. The surgical effect and complications were followed up after surgery, and an independent attending plastic surgeon evaluated the outcome and scarring based on photos before and at the last postoperative follow-up using the global aesthetic improvement scale (GAIS) and the Vancouver scar scale (VSS). GAIS is graded as 1, 2, 3, 4, and 5 points, and the lower the score, the better the improvement(≤3 points as effective improvement). VSS includes four parameters: color (0-3 points), thickness (0-4 points), vascular distribution (0-3 points), and softness (0-5 points). The higher the score, the more significant the scar is.Results:A total of 20 patients were enrolled, including 6 males and 14 females, aged 20 to 33 years, with an average age of 24.9 years. Before the operation, there were different degrees of alar flare and alar hypertrophy. After surgery, 13 patients had mild swelling, ecchymosis, which resolved after 3 days. There were no major complications as infection, incision dehiscence, and delayed healing. After 3 to 16 months of postoperative follow-up, 2 patients gradually developed cartilage deformation and affected the appearance of the nostrils 6 to 9 months after surgery due to the combination of rib-based rhinoplasty, and the satisfactory results were obtained after revision surgery. The symmetry of the nostrils was significantly improved. The GAIS score of 20 patients was (1.20±0.41) points, of which, 16 patients were rated as 1 point and 4 patients were rated as 2 points, all of which met the improvement criteria, and the VSS score was (1.45±0.60) points, in which the average score for color, thickness, vasculature and compliance are 0.60, 0.05, 0.55 and 0.30 points respectively.Conclusion:The application of jujube core-shaped tissue resection technique for alar reduction can increase the amount of tissue removal with the same incision width, which can not only fully narrow the alar effectively but also correct the hypertrophy of the alar tissue.

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

Eye movements refer to a series of spontaneous, controlled and purposeful movements of the eye. Based on a large number of observations on eye movement in scientific research and clinical work, eye movements are not only essential for maintaining clear vision in humans, but also an objective embodiment of brain activity, which is of great significance for the diagnosis and localization of multidisciplinary diseases. Eye tracking technology is a measurement technique that obtains information about eye movements. The use of eye tracking technology can obtain accurate and objective eye movement data, and explore the mechanism of eye movement, the development process and clinical significance of different eye movement types. In addition, eye tracking technology also has positive significance in the objective visual examination, diagnostic and treatment of ophthalmology. In this paper, we review the research progress of eye movements and eye tracking technology in the clinical application of ophthalmology, such as in the application of objective vision examination in infants, strabismus diagnosis and treatment, corneal refractive surgery and glaucoma diagnosis.

Objective:To investigate the clinical application of a cartilage graft fixation method in the context of rib-based rhinoplasty.Methods:The clinical data of patients who underwent costal cartilage based rhinoplasty in the Center of Rhinoplasty and Nasal Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2020 to January 2022 were retrospectively analyzed. A 20 ml syringe needle was used to drill several micropores about 1 mm in diameter on the surface of the cartilage grafts prior to its placement. "septal extension grafts with micropores" were prepared, and the preparation of the remaining grafts was conventional.Results:A total of 30 female patients aged 21-45 years, with an average age of 36 years underwent primary or repaired autogenous costal cartilage rhinoplasty without severe damage to the nasal septum cartilage (at least retention of L-shaped scaffolds larger than 10 mm) were enrolled. All operations were successful, the cartilage scaffold was stable and durable. There were no serious complications such as infection, septal hematoma and cartilage exposure. Postoperative patients were followed up for a duration of 6-24 months. Two out of 30 patients were not satisfied with the postoperative appearance. During the revision surgery, the septal perichondrium was separated, mucosal tissue had grown into the bilateral holes which further verified of the feasibility of drilling. The other patients were satisfactied with the results.Conclusion:Nasal septum extension graft based on drilling technique is beneficial to maintain the long-term stability of cartilage scaffold after comprehensive costal cartilage nasal surgery, which justifies its application in comprehensive nasal plastic surgery.

According to epidemiological surveys, the incidence of myopia among Chinese children and adolescents has risen by over 53.6%. Myopia has emerged as the leading cause of vision loss among adolescents. The mental health of students suffers from vision impairment, which has an adverse ripple effect on their ability to learn and grow, and even their physical development. Based on the observation of significant differences in mental health between myopic people and normal people, scholars at home and abroad have used various psychological scales to evaluate the association between myopia and mental health issues, including anxiety and depression, as well as personality traits such as emotionalization and introversion. This article reviews the effect of myopia on adolescent mental health and the research progress on its research methods and prevention strategies.

Objective:To investigate the long-term death of patients with ischemic stroke and its influencing factors.Methods:Based on the data of patients with ischemic stroke in the multi-center oral fibrinogen-lowering drug secondary prevention database, the follow-up patient information and the cause of death were registered through the epidemiological investigation method, and then compared with the baseline data of patients in the original database.Results:A total of 278 patients completed the follow-up, and 166 were in lumbrokinase group and 112 were in control group. There were 124 deaths (44.6%) within 10 years, of which 92 (74.2%) were vascular deaths. In the lumbrokinase group, 74 patients (44.6%) died of all causes and 55 (33.1%) died of vascular diseases; in the control group, 50 (44.6%) died of all causes and 37 (33.0%) died of vascular diseases. Cox proportional risk model analysis showed that lumbrokinase treatment had no significant effect on the 10-year survival rate of patients with ischemic stroke. The analysis of death influencing factors showed that the baseline international normalized ratio (INR) was significantly associated with the 10-year non-vascular death risk of patients (hazard ratio [ HR] 1.98, 95% confidence interval [ CI] 1.21-3.25; P=0.006). The greater the decrease of tissue plasminogen activator (tPA) within half a year, the lower the 10-year all-cause mortality risk ( HR 0.94, 95% CI 0.90-0.99; P=0.011); the greater the decrease in INR within one year , the lower the 10-year vascular death risk ( HR 0.41, 95% CI 0.17-0.96; P=0.040); the greater the decrease of D-dimer within one year , the higher the risk of the 10-year vascular death ( HR 1.37, 95% CI 1.02-1.83; P=0.034). The greater the decrease of INR in patients with ischemic stroke within one year, the higher the 10-year non-vascular death risk ( HR 2.15, 95% CI 1.29-3.59; P=0.004). Conclusions:The 10-year mortality rate of patients with ischemic stroke is higher, and about 3/4 are vascular deaths. The fibrinogen-lowering treatment in the acute stage has no significant effect on the 10-year all-cause mortality of patients with ischemic stroke. The greater the decrease of tPA in half a year, the lower the all-cause mortality; the greater the decrease of D-dimer level at baseline and within 1 year, the higher the 10-year vascular death; the greater the decrease of INR at baseline and within 1 year, the higher the 10-year non-vascular death risk.
