Patient Satisfaction After Nd:YAG Laser-Assisted Lipolysis

Fractional versus full ablative CO2 laser in recipient site of non-cultured melanocytes and keratinocyte transplantation in treatment of vitiligo

BACKGROUND

Melanocyte-keratinocyte transplant procedure (MKTP) or non-cultured epidermal cell suspension transplantation is a very popular surgical modality for treating stable vitiligo. The recipient-site preparation is one potential determinant in the repigmentation outcomes.

AIM

To assess the efficacy of fractional CO₂ (FCO₂ ) laser in recipient-site preparation before MKTP and comparing it to the frequently used full surface laser ablation.

METHODS

This randomized comparative trial included 19 patients with 40 stable vitiligo lesions. In each patient, the treated sites were randomly categorized into two groups according to the recipient-site ablation (either fractional or full ablative CO₂ laser). Assessment of repigmentation was performed six months after the procedure.

RESULTS

Both modalities achieved successful repigmentation of a median of 80% and 77.5% for fractional and full ablation groups, respectively, with a non-statistically significant difference between them. The median of VASI change percent was -73% and -71% with fractional and full surface ablation, respectively.

CONCLUSIONS

FCO₂ laser ablation is effective for recipient-site preparation before cell suspension transplantation as well as the full ablative CO₂ laser.

Experience of Comprehensive Three Dimensional Epicanthoplasty With Upper Blepharoplasty in Asian Patients

PURPOSE

To introduce the experience of comprehensive 3-dimensional epicanthoplsty with upper blepharoplasty in Asian patients.

METHODS

The patients who underwent comprehensive 3-dimensional epicanthoplsty with upper blepharoplasty at the Shanghai Ninth People's hospital from January 2018 to January 2019 were included in our study. The interepicanthal distance was evaluated preoperatively and 6 months after the surgery, scar visibility and patient's satisfaction were documented 6 months after the surgery.

RESULTS

A total of 72 patients (144 eyelids) were included in this study with ages ranging from 18 to 37 years (mean, 23.83 ± 4.64 years) and follow-up duration ranging from 6 to 12 months (mean, 7.82 ± 1.92 months). All patients were female and achieved esthetically favorable results without serious complications. No patients required revision surgery showing high patient satisfaction (score, 4.4). The preoperative mean interepicanthal distance was 33.13 ± 2.25 mm and decreased to 29.28 ± 2.26 mm postoperatively showing statistical significance (P < 0.001). Twenty-nine (40.3%) patients had no visible scarring, and 42 (58.3%) patients had minimal scarring, which was accepted by the patients.

CONCLUSIONS

The comprehensive 3-dimensional epicanthoplasty with upper blepharoplasty is a surgical technique that is easy to perform, reliable, and effective in treatment of all types of epicanthal folds except type 4 with increase intercanthal distance, less visible scar, and high patient satisfaction in Asian patients.

Evaluation of effectiveness of three-dimensional printed ear splint therapy following ear elevation surgery in microtia patients: A randomized controlled trial

AIM

This study aimed to compare the effectiveness of a 3D-printed ear splint with that of a conventional thermoplastic ear splint after microtia reconstruction.

METHODS

Patients who underwent ear elevation surgery with postauricular fascia coverage between October 2017 and October 2018 were included. They were randomly divided into the experimental group (3D-printed ear splint) and the control group (thermoplastic ear splint) and underwent routine postoperative rehabilitation and antiscar therapy. Splint therapy was initiated 4 weeks postoperatively and continued until 24 weeks postoperatively. The evaluated indices were the Vancouver scar scale score (VSS score), cranioauricular distance, patient compliance, complications (dermatitis, skin ulcers, skin necrosis), and patient satisfaction. A two-group t-test was carried out to compare all variables except patient satisfaction, which was compared using the Mann-Whitney U-test; p < 0.05 was considered significant.

RESULTS

Twenty patients were included in each group. At 4 weeks postoperatively, the VSS score (p = 0.748) and cranioauricular distance (p = 0.647) showed no significant differences between the groups. At 24 weeks postoperatively, the mean VSS scores were 4.85 ± 1.46 and 6.25 ± 1.74 (p = 0.009), the mean cranioauricular distances were 15.80 ± 1.82 mm and 13.95 ± 1.93 mm (p = 0.004), and the patient satisfaction scores were 4.5 ± 0.51 and 3.7 ± 0.47 (p < 0.001) in the experimental group and the control group, respectively, all showing significant differences. Two patients in each group exhibited skin irritation or skin ulcers, which resolved after 6 months of follow-up.

CONCLUSION

The application of 3D-printed ear splints provides better inhibition of scar contracture, better maintenance of ear projection and higher patient satisfaction than conventional ear splints following ear elevation surgery in microtia patients. Therefore, 3D-printed ear splints should be preferred over conventional ear splints whenever possible.

Evidence-based medicine: liposuction

LEARNING OBJECTIVES

After reading this article, the participant should be able to: 1. Perform preoperative assessment and patient selection for liposuction surgeries. 2. Explain the differences among the various types of anesthesia and wetting solutions used in liposuction. 3. Identify the available literature about skin-tightening procedures. 4. Convey to patients the complication profile for various modalities of liposuction. 5. Recall important ASPS consensus guidelines when discussing liposuction.

SUMMARY

The article was prepared to feature recent evidence-based publications pertaining to liposuction. The authors placed special emphasis on the most clinically relevant data. In addition, they highlighted current data regarding liposuction-related fields, including autologous fat transfer and minimally invasive skin tightening.
