Background Secondary lymphedema frequently occurs following surgery, malignancy, trauma, or radiation and is characterized by limb swelling, discomfort, and recurrent infections. Two advanced supermicrosurgical techniques—lymphovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT)—have recently gained popularity as treatment options. However, long-term outcome data for these procedures remain limited. This systematic review and meta-analysis aim to evaluate the long-term efficacy of LVA and VLNT in patients with secondary lymphedema followed for more than 2 years postoperatively, focusing on outcomes such as cellulitis rates and limb circumference. Methods This study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria encompassed studies involving adult patients with secondary lymphedema treated with LVA or VLNT and with at least 24 months of follow-up. The primary outcomes were annual cellulitis incidence and limb circumference change, analyzed separately for upper and lower extremities. Meta-analysis was conducted using R version 4.3.1. Pooled effect sizes were estimated using random-effects models. Subgroup and sensitivity analyses were also performed. Results A total of 23 studies met the inclusion criteria, covering 648 limbs treated with either LVA (n = 216) or VLNT (n = 432). The weighted average patient age was 56.3 years, and the cohort was predominantly female (99.9%). For LVA, the pooled mean reduction in annual cellulitis events was −1.13 (95% confidence interval [CI], −1.70 to −0.57) for upper extremities and −1.32 (95% CI, −2.08 to −0.55) for lower extremities. VLNT yielded greater reductions in cellulitis, with pooled mean differences of −2.43 (95% CI, −3.36 to −1.50) and −1.38 (95% CI, −2.11 to −0.65) for upper and lower limbs, respectively. Additionally, VLNT reduced limb circumference by 42.7% (95% CI, 36.7–49.7) in upper extremities and 21.98% (95% CI, 19.8–24.4) in lower extremities. Conclusion LVA and VLNT both result in durable, long-term improvements in cellulitis rates, and VLNT was shown to reduce limb circumference. Given the significant impact on patient quality of life, these interventions should remain integral to the treatment algorithm for secondary lymphedema.

Objective Describe surgical decision making and outcomes in a series of patients with persistent VPI after pharyngeal flap placement that were all treated with revision palatoplasty. Design Retrospective, case series. Participants Five patients with nonsyndromic cleft palate and persistent hypernasality following a pharyngeal flap. On MRI, 3 patients presented with an incohesive levator veli palatini muscle, and 4 patients had a pharyngeal flap that was below the palatal plane. Interventions One patient underwent straight-line intravelar veloplasty (IVVP), 2 patients underwent pharyngeal flap take-down and IVVP, and 2 patients underwent pharyngeal flap take-down and palate lengthening with buccal myomucosal flaps. Main Outcome Measure Pre- and postoperative resonance. Results Four of five patients (80%) achieved normal resonance 12 months postoperation. Conclusions Revision palatoplasty may be an effective approach for treating patients with persistent hypernasality following a pharyngeal flap. MRI may aid in surgical selection based on patient-specific anatomical findings.

Background: Over the past 10 years, smartphones have become ubiquitous, and mobile apps serve a seemingly endless number of functions in our everyday lives. These functions have entered the realm of plastic surgery, impacting patient care, education, and delivery of services. This article reviews the current uses of plastic surgery mobile apps, app awareness within the plastic surgery community, and the ethical issues surrounding their use in patient care. Methods: A scoping review of electronically available literature within PubMed, Embase, and Scopus databases was conducted in two waves in November and May 2022. Publications discussing mobile application use in plastic surgery were screened for inclusion. Results: Of the 80 nonduplicate publications retrieved, 20 satisfied the inclusion criteria. Articles acquired from the references of these publications were reviewed and summarized when relevant. The average American Society of Plastic Surgeons evidence rating of the publications was 4.2. Applications could be categorized broadly into three categories: patient care and surgical applications, professional development and education, and marketing and practice development. Conclusions: Mobile apps related to plastic surgery have become an abundant resource for patients, attending surgeons, and trainees. Many help bridge gaps in patient care and surgeon-patient communication, and facilitate marketing and practice development. Others make educational content more accessible to trainees and performance assessment more efficient and equitable. The extent of their impact on patient decision-making and expectations has not been completely elucidated.

Objective To describe current postoperative management practices following cleft palate repair. Design A survey was administered to cleft surgeons to collect information on their demographic characteristics, surgical training, surgical practice, and postoperative management preferences. Setting Eighteen tertiary referral hospitals across the United States. Participants: Surgeons (n = 67) performing primary cleft palate repair. Results Postoperative diet restrictions were imposed by 92% of surgeons; pureed foods were allowed at one week after surgery by 90% of surgeons; a regular diet was allowed at one month by 80% of surgeons. Elbow immobilizers and/or mittens were used by 85% of surgeons, for a median duration of two weeks. There was significant disagreement about postoperative use of bottles (61% allow), sippy cups (68% allow), pacifiers (29% allow), and antibiotics (45% prescribe). Surgeon specialty was not associated with any aspect of postoperative management ( p > 0.05 for all comparisons). Surgeon years in practice, a measure of surgeon experience, was associated only with sippy cup use ( p < 0.01). The hospital at which the surgeon practiced was associated with diet restrictions ( p < 0.01), bottle use ( p < 0.01), and use of elbow immobilizers or mittens ( p < 0.01); however, many hospitals still had disagreement among their surgeons. Conclusions Surgeons broadly agree on diet restrictions and the use of elbow immobilizers or mittens following palate repair. Almost all other aspects of postoperative management, including the type and duration of diet restriction as well as the duration of immobilizer use, are highly individualized.

Background: Lymphovenous anastomosis (LVA) is a microsurgical treatment for lymphedema of the lower extremity (LEL). This study systematically reviews the most recent data on outcomes of various LVA techniques for LEL in diverse patients. Methods: A comprehensive literature search was conducted in the Ovid MEDLINE, Ovid EMBASE, and Scopus databases to extract articles published through June 2021. Studies reporting data on objective postoperative improvement in lymphedema and/or subjective improvement in quality of life for patients with LEL were included. Extracted data comprised demographics, number of patients and lower limbs, duration of symptoms before LVA, surgical technique, duration of follow-up, and objective and subjective outcomes. Results: A total of 303 articles were identified and evaluated, of which 74 were ultimately deemed eligible for inclusion in this study, representing 6260 patients and 2554 lower limbs. The average patient age ranged from 22.6 to 76.14 years. The duration of lymphedema before LVA ranged from 12 months to 11.4 years. Objective rates of improvement in lymphedema ranged from 23.3% to 100%, with the greatest degree of improvement seen in patients with early-stage LEL. Conclusions: LVA is a safe and effective technique for the treatment of LEL of all stages. Several emerging techniques and variations may lead to improved patient outcomes.

Background: Lymphovenous anastomosis (LVA) is an accepted microsurgical treatment for lymphedema of the upper extremity (UE). This study summarizes and analyzes recent data on the outcomes associated with LVA for UE lymphedema at varying degrees of severity. Methods: A literature search was conducted in the PubMed database to extract articles published through June 19, 2020. Studies reporting data on postoperative improvement in limb circumference/volume or subjective improvement in quality of life for patients with primary or secondary lymphedema of the UE were included. Extracted data consisted of demographic data, number of patients and upper limbs, duration of symptoms before LVA, surgical technique, follow-up, and objective and subjective outcomes. Results: A total of 92 articles were identified, of which 16 studies were eligible for final inclusion comprising a total of 349 patients and 244 upper limbs. The average age of patients ranged from 38.4 to 64 years. The duration of lymphedema before LVA ranged from 9 months to 7 years. The mean length of follow-up ranged from 6 months to 8 years. Fourteen studies reported an objective improvement in limb circumference or volume measurements following LVA, ranging from 0% to 100%. Patients included had varying severity of lymphedema, ranging from Campisi stage I to IV. The maximal improvement in objective measurements was found in patients with lower stage lymphedema. Conclusion: LVA is a safe, effective technique for the treatment of UE lymphedema refractory to decompressive treatment. Results of LVA indicate greater efficacy in earlier stages of lymphedema before advanced lymphatic sclerosis.

AbstractBackgroundInnovation in computer‐assisted surgery (CAS) aims to increase operative accuracy and improve safety by decreasing procedure‐related complications. The application of reality technologies, to CAS has begun to revolutionize orthopedic training and practice.MethodsFor this review, relevant published reports were found via searches of Medline (PubMed) data base using the following medical subject headings (MeSH) terms: “virtual reality” or “augmented reality” or “mixed reality” with “orthopedics” or “orthopedic surgery” and all relevant reports we utilized.ResultsTrainees now have authentic and highly interactive operative simulations without the need for supervision. The practicing orthopedic surgeon is better able to pre‐operatively plan and intra‐operatively navigate without the use of fluoroscopy, gain access to three‐dimensional reconstructions of patient imaging, and remotely interact with colleagues located outside the operating room.ConclusionThis review provides a current and comprehensive examination of the reality technologies and their applications in Orthopedic surgery.
