Abstract Objective Conservative treatment with a vacuum bell (VB) for pectus excavatum (PE) has now been gradually popularized as an alternative to surgery. We describe our initial experience novel three dimensional (3D) printed VB device. Methods Prospectively collected data of all patients who started using 3D in 2018 at institution were analyzed. Linear and logistic regressions used identify factors associated effectiveness device usage. Results In total, forty-two median age 3.6 years treated the The follow-up duration was 11.1 months mean Depth Ratio (DR) 0.129. There no permanent sequelae from side effects. Thirty least one body scan showed varying improvement (z = − 4.569, p 0.0000). regression suggested that longer usage improved outcomes (R 2 0.235, 0.014). By there trend younger ages less DR better though neither statistically significant ( 0.086, 0.078, respectively). Conclusion Our shown may be effective other conventional VBs could surgical selected PE. More studies this type are needed demonstrate its superiority regard printing design optimal timing indication use.
