However, the septal cartilage in Asians often weak and small. Biocompatible absorbable materials are alternatives to autologous grafts. This study assessed the surgical outcomes and complications of poly lactic-co-glycolic acid (PLGA) plate grafts in secondary CLND correction. Methods This study was retrospectively analyzed for patients who underwent secondary rhinoplasty for unilateral CLND correction between March 2015 and November 2020. Using open rhinoplasty, the PLGA plate was grafted as a columellar strut. Clinical photographs taken at the initial (T0) and follow-up visits (T1: short-term, T2: long-term) were analyzed and anthropometric parameters, such as nostril height and width, dome height, and tip height, were measured. Results Twenty-four patients were included in this study. The mean T1 and T2 periods were 1.0 ± 0.4 and 15.5 ± 3.1 months, respectively. The nostril height ratio increased from 0.78 ± 0.12 at T0 to 0.88 ± 0.08 at T1 and 0.86 ± 0.09 at T2 (p < 0.001; Relapse ratio −2.6 ± 6.7%). The tip height ratio increased from 0.60 ± 0.07 (T0) to 0.66 ± 0.05 (T2) (Relapse ratio −3.7 ± 3.0%). Conclusions The PLGA plate graft provided stable nasal tip projection and alar symmetry without major complications. It can be a good option for patients lacking available septal and concha cartilages or apprehensive of additional scarring.

Abstract: Philtrum reconstruction in patients with unilateral cleft lip is a major concern in cheiloplasty. Moreover, a quantitative evaluation of the philtrum contour has not been possible. Advances in 3-dimensional (3D) imaging technology have enabled highly accurate assessments of facial surfaces. This study aimed to justify using 3D anthropometric measurements to quantify traditional photographic grading systems. Sixty-six children with unilateral cleft lip, aged 4 to 6 years (mean age: 69.1 +/- 5.7 mo), who visited the outpatient clinic from January to December 2020 were included. A plastic surgeon panel graded the philtrum contour using digital photographs, and 3D anthropometry was performed using a 3D imaging system. The philtrum height, philtrum height difference, and dimple depth were measured at the middle of the philtrum. The philtrum height did not show significant changes across the photographic scores (P=0.06), whereas noticeable differences were observed in the dimple depths based on photographic scores (P<0.001). The correlation analysis revealed the highest correlation between the photographic score and dimple depth (rho=0.897, P<0.001). The philtrum height on the cleft side (rho=0.478, P<0.001) also correlated with the photographic score, but the correlation was weaker than that of the dimple depth. The dimple depth and philtrum height can help define the philtrum contour. Furthermore, the dimple depth reflects the philtrum contour better and is more suitable as a single parameter. However, relying on a single philtrum height measurement may be insufficient for reliable evaluations, as the relative height from the surrounding tissues is more important than the absolute height measured using 3D anthropometry.

The puffiness is most predictable corrected by tissue resection and fat excision. Fold asymmetry, overcorrection, and recurrence can sometimes occur after levator aponeurosis manipulation. The objective of this study was to introduce a method of volume-controlled blepharoptosis correction (VC) without levator manipulation. Methods The medical records of patients who had undergone upper blepharoplasty between 2017 and 2022 were retrospectively reviewed. Questionnaires, digital photographs, and charts were used to evaluate the surgical outcomes and complications. The degree of levator function was graded as poor, fair, good, or very good. Levator function must be above good (>8 mm) to employ the VC method. Poor and fair grades of levator function were excluded because they require levator aponeurosis manipulation. The margin to reflex distance (MRD) 1 was assessed preoperatively, 2 weeks postoperatively, and at follow-up visits. Results Postoperative satisfaction was 4.3 ± 0.8 with no postoperative discomfort (0%), and the duration of swelling was 10.1 ± 2.0 days. Regarding other complications, no fold asymmetry (0%) was observed, although hematoma formation was observed in 1 (2.9%) patient in the VC group. Significant differences were observed in the changes in palpebral fissure height over time (p < 0.001). Conclusions VC can effectively correct puffy eyelids and create natural-looking, beautiful, and thin eyelids. Thus, VC is associated with higher patient satisfaction and surgical longevity without serious complications.

Despite its importance, no consensus has been reached regarding a single surgical method yet. Herein, the authors introduce a novel concept of lymphatic reconstruction yielding promising results. Methods: We included 37 patients with advanced-stage upper extremity lymphedema who underwent lymphatic complex transfers, consisting of both lymph vessel and node transfers, from 2015 to 2020. We compared the preoperative and postoperative (last visit) mean circumferences and volume ratios between the affected and unaffected limbs. Changes in the Lymphedema Life Impact Scale scores and complications were also investigated. Results: The circumference ratio (affected to unaffected limbs) improved at all measuring points ( P <.05), while the volume ratio showed a decrease from 1.54 to 1.39 ( P <.001). The mean Lymphedema Life Impact Scale decreased from 48.1 6 15.2 to 33.4 6 13.8 ( P <.05). No donor site morbidities, including iatrogenic lymphedema or any other major complications, were observed. Conclusions: A new technique for lymphatic reconstruction, lymphatic complex transfer, may be useful in cases of advanced stage lymphedema because of its effectiveness and the low possibility of donor site lymphedema.
