Objective:To evaluate the clinical efficacy of infraorbital rim drilling midface lift combined with composite lower blepharoplasty.Methods:Retrospective analysis of clinical data from the patients who underwent combined midface lift and lower blepharoplasty at Department of Medical Cosmetic Center, Affiliated Hangzhou First People’s Hospital, Westlake University School of Medical, between January 2022 and February 2024.The infraorbital rim drilling midface lift combined with lower blepharoplasty was performed via a subciliary incision approach. Through a subciliary incision, the herniated orbital fat was excised, followed by fixation of the orbital septum to the infraorbital rim periosteum. Drill holes were created at the medial and lateral infraorbital rim, and arcuate suspension of the midface was performed using 2-0 absorbable sutures (SXPP1A405). Postoperative follow-up assessed midface lifting outcomes and complication rates. The wrinkle severity rating scale (WSRS) was used to grade nasolabial folds pre- and postoperatively (5-point scale: higher scores indicating more pronounced folds). Patient-reported outcomes were assessed using the Face-Q questionnaire, evaluating: (1) overall facial satisfaction, (2) satisfaction with surgical results, and (3) satisfaction with decision (scale 0-100; higher scores indicating greater satisfaction/less decisional regret). Descriptive statistical methods were employed for data analysis.Results:A total of 43 patients were enrolled, comprising 7 males and 36 females, with a mean age of (50.6±12.2) years (range: 32-73 years). Postoperative follow-up averaged (11.9±4.6)months. All patients demonstrated significant improvement in lower eyelid bags, tear trough deformity, midface elevation, and nasolabial folds. Surgical complications included: residual lower eyelid fat ( n=5), intermittent fixation point pain persisting >1 month ( n=4), mild residual tear trough deformity ( n=4), and hematoma ( n=1). Nasolabial fold WSRS scores decreased from ( 3.7±0.9 ) points to(2.9±0.6)points following surgery. In 38 patients, Face-Q scores demonstrated high satisfaction levels: appearance-related satisfaction scored (80.9 ± 10.3)points and satisfaction with decision scored (82.4 ± 8.9)points, indicating favorable patient-reported outcomes. Conclusion:The infraorbital rim drilling-assisted midface lift combined with comprehensive lower blepharoplasty effectively corrects midface ptosis while addressing lower eyelid bags. This technique provides reliable fixation points through drilling, resulting in stable and long-lasting lifting outcomes with high patient satisfaction.

Objective:To investigate the protocol and clinical efficacy of hair follicle-bearing microskin (HF-MS) transplantation in the treatment of hypertrophic scars.Methods:Prospective randomized controlled trial. From January to November 2024, patients with hypertrophic scars were recruited from the Medical Cosmetic Center of Affiliated Hangzhou First People’s Hospital with Westlake University School of Medicine and the Department of Plastic and Reconstructive Surgery of Ningbo Sixth Hospital. Patients were randomly divided into the observation group and the control group using a random number table. In the observation group, 1.0 mm punch decompression was performed on the hypertrophic scar area, followed by implantation of HF-MS extracted from the scalp donor site using follicular unit excision (FUE) into the decompression pores. The control group underwent only 1.0 mm punch decompression. Vancouver scar scale (VSS) scores (total score 0-15, higher scores indicating more severe scarring) were assessed preoperatively and at 1, 3, and 6 months postoperatively. Efficacy at 6 months, improvement in hypertrophic scar area, hair survival rate (observation group), adverse reactions, and patients’ satisfaction rates were evaluated. Categorical data were expressed as frequency (%) and analyzed using chi-square tests; normally distributed measurement data were expressed as Mean ± SD and analyzed using independent samples t-tests. Results:A total of 50 patients were included (25 per group), with 22 males and 28 females, aged 18-60 years (mean age: 33 years). The effective rate was 92% (23/25) in the observation group and 68% (17/25) in the control group, showing a statistically significant difference ( P<0.05). Preoperative VSS scores did not differ significantly between the observation and control groups [(6.67±3.19) vs. (7.12±2.89), P>0.05]. At 1, 3, and 6 months postoperatively, the observation group had VSS scores of (5.48±2.60), (4.64±2.39), and (3.80±2.10), respectively, compared to (6.36±2.53), (5.84±2.28), and (5.32±2.09) in the control group. The 6-month postoperative VSS scores differed significantly between groups ( P<0.05). Preoperative hypertrophic scar areas showed no significant difference [(5.75±2.83) cm 2 vs. (6.91±3.31) cm 2,P>0.05]. At 6 months postoperatively, the observation group had significantly smaller scar areas than the control group [(3.15±1.55) cm 2 vs. (5.37±2.93) cm 2,P<0.01]. The average hair survival rate in the observation group was 41% at 6 months. Adverse reactions occurred in 3 cases in the observation group (2 skin indurations, 1 hyperpigmentation) and 7 cases in the control group (4 hyperpigmentation, 2 skin atrophy, 1 skin induration). The observation group had a significantly lower adverse reaction rate [12% (3/25) vs. 28% (7/25), P<0.05]. Patient satisfaction rates were 88% (22/25) in the observation group and 64% (16/25) in the control group ( P<0.05). Conclusion:HF-MS transplantation demonstrates definitive clinical efficacy in treating hypertrophic scars, effectively improving scar morphology, clinical symptoms, and patient quality of life.

Objective:To evaluate the effect of esketamine on the quality of postoperative sleep in preschool children undergoing day surgery.Methods:This was a prospective randomized controlled study. One hundred and four preschool children of either sex, aged 4-7 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, underwent elective day surgery for strabismus correction under general anesthesia at the First Affiliated Hospital of Zhengzhou University from July to September 2024, were selected. The preschool children were divided into 2 groups ( n=52 each) by the random number table method: control group (group C) and esketamine group (group S). In group S, additional esketamine 0.25 mg/kg was intravenously injected during anesthesia induction. The sleep quality scores were evaluated using the Children′s Sleep Habit Questionnaire by the guardians on the night before surgery, the 1st night after surgery, the 3rd night after surgery and the 7th night after surgery, and development of postoperative sleep disorders (the Children′s Sleep Habit Questionnaire score >41) was recorded. The FLACC pain scores and usage rate of flurbiprofen axetil were recorded immediately before leaving the postanesthesia care unit (PACU) and on days 1, 3 and 7 after surgery. The time of laryngeal mask airway removal, length of stay in PACU and development of adverse reactions such as increased oral secretions, agitation, nausea and delirium within 48 h after surgery were recorded. Results:Compared with group C, the Children′s Sleep Habits Questionnaire score and incidence of postopoerative sleep disorders were significantly decreased on the 1st night after surgery, the FLACC pain scores were decreased immediately before discharge from the PACU and at 1 day after surgery, the usage rate of flurbiprofen axetil was decreased ( P<0.05), and no significant change was found in the time of laryngeal mask airway removal, length of stay in PACU and incidence of postoperative adverse reactions in group S ( P>0.05). Conclusions:Anesthesia induction with esketamine 0.25 mg/kg can improve the quality of postoperative sleep in preschool children undergoing day surgery.

Objective:To investigate the efficacy and safety of transurethral incision for the treatment of ureterocele in infants.Methods:A retrospective analysis of 28 cases of ureterocele admitted from March 2012 to May 2023 were reviewed, all of which were less than 1 year old, 16 male and 12 female, with an average age of(5.7±3.5)months. The ureterocele was located on the left side in 8 cases, on the right side in 15 cases, and bilaterally in 5 cases. There were 12 cases of single system ureterocele, of which 7 cases were unilateral and 5 cases were bilateral. Duplex system ureterocele was observed in 16 cases, all of which were unilateral. Clinical manifestations: urinary tract infection in 13 cases, 11 cases of ureterocele or hydronephrosis and ureteral dilation were found during antenatal examination, and 4 cases of ureterocele were found after birth. Urological ultrasound, intravenous pyelography(IVP) and voiding cystourethrography(VCUG) were performed in all children, and 17 cases underwent magnetic resonance urolography (MRU), and confirm the diagnosis of ureterocele preoperatively. All of the cases were performed the transurethral incision.The ureterocele was punctured and incised 1-2 mm at the base of the bulge, and 2-4 points were punctured according to the bulge atrophy. Bilateral ureteroceles were punctured and incised simultaneously. Postoperative urine routine test, urinary tract color ultrasound and VCUG were performed to determine if there is urinary tract infection, hydronephrosis, ureteral dilation and bulging, and whether a second surgery is needed.Results:All operations were conducted successfully. The intraoperative bleeding was less than 3 ml and no intraoperative complications. The operative time was (28.4±10.3) min. The median postoperative follow-up was 34 (32, 36) months. Six cases underwent postoperative VCUG examination. Eleven children were recovered well with single systemic ureterocele. One child developed grade Ⅳ vesicoureteral reflux(VUR)and combined with bladder diverticulum, and ureterocele underwent open diverticulotomy and ureteral reimplantation six months after surgery. Nine children were recovered well with duplex systemic ureterocele. Six cases of children developed infection, of which 2 cases had an infection once within one month after TUI, and the other four cases still had intermittent infections after six months and VCUG was performed, and one case showed grade Ⅲ VUR of the lower ureter, which was observed conservatively, while the other three cases had enlarged cysts but no VUR, and upper heminephrectomy was performed, and the patients recovered well after surgery. Except for these 6 exceptions, in another case, after ten years of follow-up, the ureterocele became larger but no VUR, and the results were good after a second transurethral incision. There was no significant difference in the postoperative infections, new VUR cases, and secondary surgeries between the two groups.Conclusions:Transurethral incision has good surgical effect on children with single system ureterocele and duplex system ureterocele, and has advantages of easy operation, less trauma, safety and effectiveness, and few complications. It deserves to be recommended as the treatment of choice, especially for infants and young children.
