Objective To compare perioperative outcomes, complications, imaging utilization, and device management following posterior vault distraction osteogenesis (PVDO) and spring-mediated cranioplasty (SMC) for multisutural craniosynostosis. Design Retrospective cohort study. Setting Single pediatric tertiary care center. Patients, Participants Twenty-three patients with multisutural craniosynostosis treated between 2017 and 2025 (PVDO, n = 18; SMC, n = 5). Interventions PVDO or SMC. Main Outcome Measure(s) Time to device removal, imaging utilization, reoperations, readmissions, device-related complications, revision surgeries, wound infections, and absolute intracranial volume change. Results PVDO was associated with earlier device removal than SMC (78.7 ± 22.1 vs. 133.0 ± 27.4 days; P = .0015) but greater postoperative imaging utilization during the first year (5.33 ± 1.28 vs. 2.80 ± 1.64 studies; P = .01). Rates of reoperation (22.2% vs. 0%), readmission (22.2% vs. 40.0%), device-related complications (11.1% vs. 0%), revision surgery (16.7% vs. 0%), and wound infection (22.2% vs. 20.0%) did not differ significantly (all P ≥ .50). Preoperative imaging utilization and postoperative intracranial volume gain were comparable between groups. Conclusions PVDO and SMC demonstrated similar safety profiles and intracranial volume expansion in patients with multisutural craniosynostosis. Compared with SMC, PVDO enabled earlier device removal but required increased postoperative imaging. These findings may inform operative planning, postoperative surveillance, and family counseling. Larger, multicenter studies with longer follow-up are needed to evaluate long-term outcomes.

Background: Tranexamic acid (TXA) is widely used in craniosynostosis surgery to reduce blood loss. Although the efficacy of TXA administration has been documented in the literature, dosing in the perioperative setting is variable and without a standard protocol. The purpose of this study is to determine the efficacy of continuing TXA postoperatively for patients undergoing suturectomy for metopic or unicoronal synostosis. Methods: We conducted a retrospective cohort study evaluating the use of postoperative TXA infusion in patients undergoing suturectomy for metopic and unicoronal craniosynostosis. All patients received a TXA bolus of 10 mg/kg at the time of surgical prep, followed by a TXA infusion at 5 mg/kg/hour during the procedure. Patients undergoing suturectomy for metopic or unicoronal synostosis in 2020 to 2021 received postoperative TXA infusion at 5 mg/kg/hour for the first 4 hours after surgery. Following a protocol change in anemia management at the institution in 2022, patients undergoing this surgery in 2022 did not receive a postoperative TXA infusion. Chart review was performed, and mean hemoglobin values were compared between patients who received postoperative TXA and those who did not, with analyses stratified by suture involvement to determine the impact of the protocol change. Results: Twenty-eight patients met the inclusion criteria: 14 patients received postoperative TXA, and 14 patients did not. Both groups included 8 patients undergoing metopic suturectomy and 6 patients undergoing unicoronal suturectomy. For patients who underwent metopic suturectomy and received postoperative TXA, the mean preoperative hemoglobin was 11.4 g/dL, and on postoperative day 1 (POD1) was 8.1 g/dL. For patients who underwent metopic suturectomy and did not receive postoperative TXA, the mean preoperative hemoglobin was 11 g/dL and on POD1 was 9.2 g/dL ( P =0.27). The differences in mean preoperative and postoperative hemoglobin were not statistically significant between the 2 cohorts, P =0.15 and P =0.20, respectively. For patients who underwent unicoronal suturectomy and received postoperative TXA, the mean preoperative hemoglobin was 12 g/dL, and on POD1 was 8.7 g/dL. For patients who underwent unicoronal suturectomy and did not receive postoperative TXA, the mean preoperative hemoglobin was 11.4 g/dL and on POD1 was 9.1 g/dL ( P =0.36). The mean preoperative and postoperative hemoglobin were not statistically different between the 2 cohorts, P =0.42 and P =0.92, respectively. Hospital length of stay averaged 1 day across both cohorts. No patient received a postoperative blood transfusion. Conclusion: In patients undergoing suturectomy for metopic or unicoronal craniosynostosis, postoperative TXA infusion made no significant difference in postoperative hemoglobin levels, length of stay, or postoperative transfusion. Discontinuing postoperative TXA could potentially decrease monitoring needs and lower hospital costs.

Objective To evaluate the incidence and characteristics of secondary synostosis following spring-mediated cranioplasty (SMC) for nonsyndromic sagittal craniosynostosis. Design Retrospective cohort study. Setting Single tertiary pediatric hospital. Patients/Participants Ten patients with isolated sagittal craniosynostosis who underwent primary SMC between 2021 and 2023. Patients with syndromic diagnoses or prior cranial surgery were excluded. Interventions SMC was performed using 2 to 3 stainless-steel springs following sagittal strip craniectomy. Springs were typically removed 3 to 4 months postoperatively. Follow-up included review of clinical photographs, radiographs, and operative records. Main Outcome Measures Change in cephalic index (CI) from preoperative to postoperative assessment and occurrence of secondary suture fusion, particularly coronal synostosis. Results Mean age at surgery was 4 months (range, 3-6 months). Mean CI improved from 68.5 to 79 following expansion. Three patients (30%) developed left unicoronal synostosis (UCS) during the perioperative period prior to spring removal. One patient required secondary coronal suturectomy for significant frontal asymmetry, while 2 were observed without intervention. Conclusions Secondary synostosis, particularly UCS, may represent an underrecognized sequela of SMC. Altered biomechanical forces or asymmetric cranial remodeling during distraction may contribute to this finding. Larger, multicenter studies with longitudinal imaging are warranted to determine incidence, risk factors, and preventive strategies.

Objective Prior work has identified numerous barriers to standardized outcome measurement in cleft care. The objective of this study was to evaluate a multifaceted implementation strategy to collect standardized outcomes for children with cleft lip and/or palate (CL/P). Design A one-armed, single-site pilot study of a multifaceted implementation strategy. Setting A metropolitan children's hospital. Patients Five-year-old children with CL/P. Interventions A multifaceted implementation strategy for standardized outcome measurement. Main Outcomes Measures The primary outcome measure was penetration of the intervention, defined as the proportion of children for whom the standardized measures of aesthetic, dental, and speech outcomes were collected. Penetration pre-implementation and 12 months post-implementation were compared. The secondary outcome was acceptability of standardized outcome measurement among providers and staff, evaluated with the Acceptability of Intervention Measure. Results The implementation strategy resulted in high penetration of standardized outcome measurement: measurement of aesthetic outcomes increased from 7% to 82% ( p < .0001); measurement of dental outcomes increased from 0% to 56% ( p < .0001); measurement of speech outcomes increased from 29% to 77% ( p = .0001). Acceptability of standardized outcome measurement was high, with 93% of cleft team providers and staff (n = 14/15) reporting that they somewhat or completely agreed that standardized outcome measurement met their approval, was appealing, was welcomed, and was liked. Penetration continued to improve after the implementation period, with high rates of outcome measure collection sustained for four years following implementation. Conclusions Deployment of a multifaceted implementation strategy led to substantial increases in the collection of aesthetic, dental, and speech outcomes among children with CL/P.

Objective: Our objective is to examine which sociodemographic factors may influence the time of presentation of patients with craniosynostosis, which can impact perioperative outcomes. Design: Retrospective cohort study. Setting: Tertiary pediatric hospital. Patients, Participants: All patients with nonsyndromic sagittal synostosis who underwent surgery at a tertiary pediatric hospital from January 1, 2007 to January 2, 2024 were eligible for inclusion. Interventions: Comparing demographic variables between those undergoing early and late craniosynostosis repair. Main Outcome Measure(s): Demographic variables, social vulnerability index (SVI) and area deprivation index (ADI), median household income, education rate, and employment rates. Results: 77.5% (n = 234) of patients underwent minimally invasive repair. 22.5% (n = 68) underwent open cranial vault remodeling. Age at consultation differed significantly between those undergoing early repair compared to late repair (0.18 years v. 1.01 years, P < .0001). Patients undergoing late repair were more likely to be Hispanic (42.6% v. 24.4%, P = .0378), on public insurance (66.2% v. 45.3%, P = .0079), have lower parental education rates (24.78% vs. 31.64%, P = .0019), and lower median household income ($65 657 vs. $75 281, P = .0226). Interestingly, ADI scores and SVI scores did not significantly differ between groups. Conclusions: Patients who presented later for treatment of nonsyndromic sagittal synostosis had lower median household income, were more likely to be Hispanic, had lower parental education rates, and were more likely to be on public insurance compared to those who received early treatment.

Objective: Describe changes in symptoms of velopharyngeal insufficiency (VPI)—hypernasality, audible nasal emission, and VPI-related quality of life—following LeFort I osteotomy in individuals with cleft palate +/- cleft lip. Design: Single-center, retrospective cohort study. Participants: Twenty-one patients with a history of cleft palate repaired in infancy were included in this study. Ten patients had no prior history of VPI surgery and eleven had a pharyngeal flap in place at the time of LeFort I osteotomy. The mean age at time of surgery was 17.2 years. Main Outcome Measure: Pre- and postoperative hypernasality severity, frequency of audible nasal emission, and total score on the VPI Effects on Life Outcomes youth questionnaire (VELO-Y) before and after LeFort osteotomy I. Fischer exact test was used to assess differences between groups for categorical variables and a t test was used for continuous variables. Results: Patients with no prior history of VPI management had a significant increase in hypernasality severity compared with those with a pharyngeal flap in place at the time of surgery ( P =0.004). Patients without a prior history of VPI management also had a significant increase in frequency of audible nasal emission, while patients with a pharyngeal flap had decreased audible nasal emission ( P =0.004). There was not a significant difference between groups for change in the total score on the VELO-Y ( P =0.16). Conclusions: Findings from this study may improve preoperative counseling provided to patients and caregivers on the risk of acquiring VPI after LeFort I osteotomy based on prior VPI surgical history.

Background: Positioning the pharyngeal flap base high along the posterior pharyngeal wall is essential for optimizing speech outcomes. Objective data on where to place the flap base are lacking. Further, adenoid tissue can restrict cephalad positioning of the flap. This study aimed to improve the design of the pharyngeal flap by measuring the distance from the first cervical vertebrae (C1) to the palatal plane, and the adenoid depth in children undergoing evaluation for velopharyngeal insufficiency. Methods: This retrospective cross-sectional study analyzed magnetic resonance imaging (MRI) scans of the velopharynx and measured the distance between C1 and the palatal plane, and the adenoid depth at the level of the palatal plane in millimeters. Results: Thirty-four patients met the inclusion criteria. The mean age at the time of MRI was 7.4 years (range: 3.9–11.9 y). The anterior tubercle of C1 was below the palatal plane in 97% (n = 33) of patients. On average, this landmark was 10.5 mm (SD = 5.0) below the palatal plane. Adenoid tissue was present at the level of the palatal plane in 91% (n = 31) of patients. Conclusions: Positioning the pharyngeal flap base at C1 is too low to aid with velopharyngeal closure. Further, adenoid tissue is frequently present at the level of velopharyngeal closure, limiting superior positioning of the pharyngeal flap base. When this occurs, surgeons should consider adenoidectomy before pharyngeal flap surgery. Preoperative MRI may be beneficial for planning pharyngeal flap positioning relative to C1 and assessing adenoid tissue at the palatal plane.

Craniofacial surgery requires a multidisciplinary care approach in the perioperative period. In an effort to guide clinical decision making and standardize care, many institutions have implemented craniofacial surgical pathways, describing numerous variables to monitor and specific actions that must be completed by each involved discipline in the perioperative period. Adherence to these pathways can be challenging given the complexity of the protocol and the multiple disciplines involved. In an effort to improve adherence to our institution’s perioperative pathway, the authors implemented a quarterly, multidisciplinary craniofacial operative team meeting to review the pathway and improve the quality of care. The authors report results from a retrospective review of craniosynostosis suturectomy operations at a single site in the 2 years before and 2 years after the start of our team meeting to review perioperative care. A total of 141 operations were included (70 before the meeting and 71 after). Perioperative outcomes and adherence to our surgical pathway were compared. Following the start of our team meetings, there was a significant decrease in the time under anesthesia, patients requiring blood transfusion, and total hospital length of stay ( P <0.05). There was also improved adherence to the craniofacial pathway, with significantly more operations applying peripheral nerve blocks to all locations specified in our pathway with the proper drug contents ( P <0.05). Our findings suggest that craniofacial operative team meetings with a goal of reviewing the surgical pathway and discussing improvements in care plans with all involved providers can significantly improve adherence to operative pathways and surgical outcomes.

Background: Latinas with mammographic dense breasts are at increased risk of breast cancer. This randomized controlled trial tests the effectiveness of three breast density (BD) educational approaches on adherence to subsequent mammography screening among Latinas receiving care at a Federally Qualified Health Center (FQHC). Measure(s): Adherence was ascertained using electronic health record and survey responses. Kaplan–Meier estimates of the time to subsequent mammogram were used to obtain adherence rates at 1- and 2-years post baseline mammogram. Cox modeling assessed whether adherence differed by patient characteristics or group assignment. Results: This analysis was limited to Latinas enrolled between October 27, 2016, and December 21, 2018 ( n = 946; 66.1% <50 years of age, 53.5% with dense breasts). Adherence rates at 1 year was 24.8% increasing to 51.7% by year 2. Latinas randomized to the Promotora + brochure + letter arm (hazard ratio [HR]: 1.09 [95% confidence interval [95% CI] 0.87 to 1.36]) or brochure + letter (HR: 1.03 [95% CI 0.82 to 1.29]) arm were not more likely to be adherent to subsequent mammography compared to the letter only arm ( p = 0.76) . Adjusting for age and study group, having more prior mammograms, being “extremely likely” to get an annual mammogram, and having more confidence to get an annual mammogram at baseline were significant drivers of subsequent adherence. Conclusion: Informational interventions targeting BD education alone are unlikely to significantly improve adherence to subsequent mammography among Latinas receiving care in FQHCs.

Purpose The Sangre Por Salud (SPS) Biobank was established to facilitate biomedical research opportunities for the Latino community by creating an easily accessible prospective cohort for scientists interested in studying health conditions and health disparities in this population. Participants Individuals self-identifying as Latino, aged 18–85 years, were prospectively recruited from the primary care Internal Medicine clinic at Mountain Park Health Center in Phoenix, Arizona. After obtaining informed consent, detailed medical history questionnaires were captured, and blood samples were obtained for common laboratory tests. Participants authorised the research team to access their electronic health records for research purposes. In addition, participants had serum, plasma and DNA samples isolated and stored at the Mayo Clinic Arizona Biorepository Laboratory for long-term storage and future access. As part of the study, participants consented and agreed to be contacted for potential participation in future research studies. Findings to date 3756 participants provided informed consent, of whom 3733 completed all study questionnaires, an oral glucose tolerance test and had blood collected and stored. The SPS cohort is predominantly composed of females (72%), with a median age at time of consent of 42 years. All participants self-identified as Hispanic/Latino, 45% were married, 53% were employed for wages and 60% had less than a high school degree. Around 25% of participants met diagnostic criteria for overweight (BMI 25–29 kg/m 2 ), and 49% met for obesity (BMI≥30 kg/m 2 ). At time of recruitment, hypertension, hyperlipidaemia and depression affected 22%, 20% and 13% of the cohort, respectively. Future plans We plan to regularly update the participants’ electronic health records and self-reported health data to longitudinal research. Additionally, we plan to obtain a more comprehensive genomic analysis on the entire cohort, ensuring greater research interest and investigation into the underlying genetic factors that contribute to disease susceptibility in this cohort.
