ABSTRACT
PURPOSE: We examined differences in long-term morphometric outcomes of spring-mediated cranioplasty (SMC) for various forms of isolated nonsyndromic sagittal craniosynostosis. METHODS: A retrospective review was performed of children who underwent SMC from 2011 to 2020 at the Children's Hospital of Philadelphia. Cephalic indices (CI), Whitaker grades, parietal bone thickness, and degree of suture fusion were assessed. Frontal bossing and vertex-nasion-opisthocranion (VNO) angles were compared to a normal control group. RESULTS: Fifty-four subjects underwent surgery at age 3.6 ± 1.0 months with follow-up of 6.3 ± 1.8 years. Mean CI was 75.2 ± 4.1 at 5.9 ± 2.0 years postoperatively. Mean CI were 75.8 ± 4.1 (n = 32), 76.4 ± 4.0 (n = 22), and 77.1 ± 4.8 (n = 11) at 5, 7, and 9+ years postoperatively, respectively. Three (5.6%) required reoperation for persistent scaphocephalic cranial deformity. Fifty-one (94.4%) were Whitaker Grade I. On physical examination, 12 (22.2%) demonstrated craniofacial abnormalities. At long-term follow-up, there were no differences in frontal bossing angle (102.7 ± 5.2 degrees versus 100.7 ± 5.6 degrees, p = .052) and VNO angle (44.9 ± 3.3 degrees versus 43.9 ± 2.2 degrees, p = .063) between study and control groups. Younger age at surgery predicted a lower Whitaker grade, more normalized VNO angle, and greater change in CI during active expansion. Increased percentage fused of the posterior sagittal suture predicted a higher Whitaker grade, while decreased anterior fusion was associated with frontal bossing and temporal hollowing. CONCLUSIONS: Overall, children undergoing spring-mediated cranioplasty for sagittal craniosynostosis demonstrated maintenance of CI, favorable cosmetic outcomes, and a low reoperation rate at mid-term follow-up. Early intervention is associated with improved aesthetic outcomes, and regional fusion patterns may influence long-term craniofacial dysmorphology.
ABSTRACT
BACKGROUND: The use of post-mastectomy radiation therapy (PMRT) in the setting of immediate two-stage breast reconstruction is becoming increasingly widespread. However, the timeframe of tissue expander exchange for permanent implant placement following PMRT is not well-defined, and it remains unclear what time interval optimizes surgical outcomes and patient satisfaction. METHODS: A systematic review conducted in accordance with PRISMA 2020 was completed. PubMed, Embase, Scopus, and Cochrane databases were searched under keywords pertaining to concepts of tissue expander breast reconstruction and PMRT. Inclusion criteria encompassed primary articles on tissue expander breast reconstruction with adjuvant radiation therapy reporting timing of exchange to permanent implant following radiation and surgical outcomes. RESULTS: Of the initial 1,259 publications, 15 studies met our inclusion criteria, and 11 studies had granular enough data to use for pooled analysis. Implant exchange less than 6 months after PMRT was found to be associated with increased incidence of wound dehiscence (17.12% vs 3.64%, p<0.001) and hematoma (25% vs 2.59%, p<0.001) compared to exchange after 6 months. There was no significant difference in incidence of SSI, seroma, capsular contracture, and reconstructive failure. CONCLUSIONS: Expander to implant exchange at less than 6 months is associated with a higher incidence of wound dehiscence and hematoma formation but does not increase the risk of reconstruction failure. The limited research on ideal timing prompts further investigation to optimize surgical outcomes for the increasing patient population undergoing PMRT and immediate two-staged breast reconstruction.
ABSTRACT
INTRODUCTION: The prevalence of obesity has risen worldwide, posing a problem to surgeons as obesity is a well-known risk factor for surgical outcomes. While prior studies have suggested performing reduction mammaplasty (RM) in patients with obesity, the variance in outcomes and quality of life (QoL) for obesity classes are ill-defined. We investigated whether obesity classes should be considered for RM by examining the surgical outcomes and QoL across different weight classes, aiming to pinpoint when outcomes become less favorable. METHODS: Patients undergoing RM by nine surgeons from 2016 to 2022 were included. Body mass index (BMI) cohorts were formed according to the Center for Disease Control and Prevention (CDC) guidelines: Healthy (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), obesity class I (30-34.9 kg/m2), II (35-39.9 kg/m2), and III (>40 kg/m2). QoL was assessed by comparing preoperative and postoperative BREAST-Q scores within cohorts. A comparison analysis was performed between weight classes. RESULTS: A total of 461 RM patients were identified (healthy: 83, overweight: 178, I: 142, II: 39, III: 19). Percentage of Black patients, procedure length, weight of tissue removed, and inferior pedicle technique all significantly increased as BMI increased (P < 0.001). Higher BMI cohorts, especially class III, had significantly higher rates of surgical site infections (healthy: 0%, overweight: 1.1%, I: 1.4%, II: 0%, III: 15.8%, P < 0.01), fat necrosis (healthy: 1.2%, overweight: 5.1%, I: 7%, II: 0%, III: 22.2%, P = 0.01), dehiscence (healthy: 3.6%, overweight: 2.8%, I: 2.1%, II: 5.1%, III: 31.6%, P < 0.01), delayed healing (health: 4.8%, overweight: 11.2%, I: 16.9%, II: 28.2%, III: 42.1%, P < 0.01), minor T-point breakdown (healthy: 10.8%, overweight: 15.7%, I: 23.9%, II: 23.1%, III: 52.6%, P = 0.01), and surgical site occurrence requiring procedural intervention (healthy: 6.0%, overweight: 5.6%, I: 6.3%, II: 15.4%, III: 21.1%, P < 0.05). When compared to the other weight classes independently, class III was associated with unfavorable outcomes (P < 0.05). Significant improvement in average postoperative QoL scores in satisfaction with breast, psychosocial well-being, sexual well-being, and physical well-being were seen in all cohorts except class III (P < 0.05). CONCLUSIONS: Severe obesity class III patients undergoing RM have a higher yet still acceptable risk profile and should be counseled on the risks despite its improved quality of life.
ABSTRACT
INTRODUCTION: Vascular malformations (VMs) typically appear at birth and grow commensurately with patients. They can vary broadly in vessel type and tissue involvement, and upper extremity (UE) VMs can pose unique functional and aesthetic challenges in children. Given the advent of operative and nonoperative technologies like sclerotherapy and medications, a contemporary review of the surgical management of UE VMs is warranted. METHODS: We performed a retrospective review of all patients who had surgical management of VMs from 2010 to 2021 at The Children's Hospital of Philadelphia. Demographics, lesion characteristics, treatment (including preceding nonsurgical therapies), complications, and final outcomes were recorded. Operative notes were reviewed for date of operation, depth of excision, type of closure, and current procedural terminology code. RESULTS: Sixty-seven patients with 88 procedures were studied. Average patient age was 5.8 years, with 64% White and 67% male. Venous (34%) and lymphatic (19%) malformations were most common, and anatomic locations were most frequently on the hand (33%) and forearm (25%). The average lesion diameter was 4.2 cm, although this varied by location (eg, 2.9 cm, hand; 11.1 cm, chest wall). Fifty-eight patients (87%) underwent surgical excision as their index procedure, and 9 had sclerotherapy before surgery. Thirty-nine patients (60%) had subcutaneous excisions, and the remainder required subfascial or intramuscular excisions. Nearly all excisions were closed primarily (97%). Of the 53 patients with documented follow-up, 32 patients (60%) had complete resolution of their lesion as of their final visit. Thirty of these 32 patients with no clinical evidence of residual VM had only 1 surgery for excision. CONCLUSION: Upper extremity VMs were composed of diverse conditions with varying vessel types, size, depth, and anatomic sites. Surgical excision of VMs of the UE was safe and effective. A majority of VMs were fully excised after 1 procedure and frequently closed primarily with relatively low complication rates. Future work should investigate decision-making and outcomes of all treatment options of VMs of the UE for optimal functionality and aesthetics.

Pulmonary squamous cell carcinoma is the second most common lung cancer subtype and has a low 5-year survival rate at 17.6%. Complete resection with negative margins can be curative, but a high number of patients suffer early postoperative recurrence due to inadequate disease clearance at the index operation. Intraoperative molecular imaging (IMI) with tumor-targeted optical contrast agents is effective in improving resection completeness for other tumor types, but there are no IMI tracers targeted to pulmonary squamous cell carcinoma. In this report, we describe the use of a novel prostate-specific membrane antigen (PSMA)-targeted near-infrared conjugate (OTL78) to identify pulmonary squamous cell carcinoma. We identified PSMA as a viable target by examining its expression in human lung tumor specimens from a surgical cohort. Ninety-four percent of tumors expressed PSMA in either the pulmonary squamous cells or the tumor neovasculature. Using in vitro and in vivo models, we found that OTL78 reliably localized pulmonary squamous cell carcinoma in a PSMA-dependent manner. Finally, we found that IMI with OTL78 markedly improved surgeons' ability to identify residual disease after surgery in a preclinical model. Ultimately, this novel optical tracer may aid surgical resection of pulmonary squamous cell carcinoma and potentially improve long-term outcomes.
