Digital Impressions from Newborns to Preschoolers with Cleft Lip and Palate: A Two-Centers Experience

Inpatient versus Outpatient Alveolar Bone Grafting: A Nationwide Cost Analysis

OBJECTIVE

To compare postoperative outcomes and costs between inpatient and outpatient ABG in the United States.

DESIGN

Retrospective cohort.

SETTING

Multi-institutional/national.

PATIENTS AND PARTICIPANTS

Patients who underwent ABG (n = 6649) were identified in the National Surgical Quality Improvement Program Pediatric database from 2012-2021. Inpatient and outpatient cohorts were matched using coarsened exact matching.

MAIN OUTCOMES MEASURE(S)

Thirty-day readmission, reoperation, and complications. A modified Markov model was developed to estimate the cost difference between cohorts. One-way and probabilistic sensitivity analyses were performed.

RESULTS

After matching, 3718 patients were included, of which 1859 patients were in each hospital-setting cohort. The inpatient cohort had significantly higher rates of reoperations (0.6% vs. 0.2%; p = 0.032) and surgical site infections (0.8% vs. 0.2%; p = 0.018). The total cost of outpatient ABG was estimated to be $10,824 vs. $20,955 for inpatient ABG, resulting in $10,131 cost savings per patient. Probabilistic sensitivity analysis revealed that all 10,000 simulations resulted in consistent cost savings for the outpatient cohort that ranged from $8000 to $24,000.

CONCLUSIONS

Outpatient ABG has become increasingly more popular over the past ten years, with a majority of cases being performed in the ambulatory setting. If deemed safe for the individual patient, outpatient ABG may confer a lower risk of nosocomial complications and offer significant cost savings to the healthcare economy.

Comparative study on cleft palate morphology after passive presurgical plate therapy in unilateral cleft lip and palate

BACKGROUND

Presurgical plate therapy has been widely accepted as a treatment prior to palatal cleft closure. The effects of passive presurgical plate therapy on cleft morphology prior to single-stage unilateral cleft lip and palate (UCLP) repair were quantified.

PATIENTS AND METHODS

We compared the dimensions of cleft width and cleft area (true cleft and palatal cleft) measured preoperatively at 2 European cleft centers. Center A performed single-stage UCLP repair in 8-month-old infants without any presurgical orthopedic treatment. Center B initiated passive presurgical plate therapy immediately after the birth of the neonates, followed by single-stage UCLP repair at 8 months of age.

RESULTS

We included 28 patients with complete UCLP from Center A and 12 patients from Center B. The average anterior width of the true cleft before surgery was significantly smaller in infants at Center B than that in Center A (p = 0.001) with 95% confidence interval of (1.8, 5.7) mm, but the average posterior width was similar in the 2 groups. The mean presurgical true cleft area amounted to 106.8 mm2 (SD = 42.4 mm2) at Center A and 71.9 mm2 (SD = 32.2 mm2) at Center B, with a confidence interval for the difference being (9.8, 60.1) mm2. This corresponded to a 32.7% reduction of the true cleft area when passive presurgical plate therapy was used for the first 8 months of the infants' life.

CONCLUSION

Passive presurgical plate therapy in UCLP significantly reduced the cleft area. Implications for the subsequent surgical outcome might depend on the surgical technique used.

Three-Dimensional Printable Open-Source Cleft Lip and Palate Impression Trays: A Single-Impression Workflow

SUMMARY

Documenting complex three-dimensional (3D) cleft lip and palate malformation with plaster casts based on maxillary impressions is standard care. Presurgical orthopedic treatment also requires an impression. Digital impression-taking in patients with cleft lip and palate is feasible, but procurement costs hinder clinical implementation. Individualized impression trays allow for a precise impression, limiting airway risk. The authors present an open-source impression tray library with scalable impression trays not requiring 3D modeling knowledge. The cleft lip and palate impression tray library is accessible on Open Science Framework. Different shapes are available, and the tray size is selected based on the tuber distance. This allows 3D printing with biocompatible material at the point of care complying with local regulations. The open-source cleft tray library presented offers a hybrid solution for cleft centers, pending the implementation of digital impression.

A Point-of-Care Digital Workflow for 3D Printed Passive Presurgical Orthopedic Plates in Cleft Care

Cleft lip and palate are one of the most common congenital craniofacial malformations. As an initial treatment, presurgical orthopedics is considered standard treatment at many cleft centers. Digital impressions are becoming feasible in cleft care. Computer-aided design (CAD) and three-dimensional (3D) printing are manufacturing standards in dentistry. The assimilation of these technologies has the potential to alter the traditional workflow for the fabrication of customized presurgical orthopedic plates. We present a digital workflow comprising three steps: 3D digital image acquisition with an intraoral scanner, open-source CAD modeling, and point-of-care 3D printing for the fabrication of personalized passive presurgical plates for newborns with cleft lip and palate. The digital workflow resulted in patient-related benefits, such as no risk of airway obstruction with quicker data acquisition (range 1–2.5 min). Throughput time was higher in the digital workflow 260–350 min compared to 135 min in the conventional workflow. The manual and personal intervention time was reduced from 135 min to 60 min. We show a clinically useful digital workflow for presurgical plates in cleft treatment. Once care providers overcome procurement costs, digital impressions, and point-of-care 3D printing will simplify these workflows and have the potential to become standard for cleft care.
