“…Moreover, personalized treatment is urgently needed to find suitable candidates, improve treatment compliance, and improve outcomes. In previous studies, a simple change in the use time, pressure, or frequency of VB during the treatment period in all patients may not address the conflict between compliance and the treatment protocol ( 14 , 15 , 21 , 22 ). Although prolonged usage time may be associated with better outcome, it may result in poor treatment compliance and the discontinuation of VB therapy.…”

ObjectiveThe outcome of vacuum bell (VB) treatment for preschool patients with pectus excavatum (PE) is poorly understood. We aim to investigate the short-term treatment effect of VB with a three-dimensional scanner and assess the clinical and demographic factors that might influence treatment outcomes.MethodsWe conducted a chart review study to review the records of preschool patients with PE who received VB treatment in a tertiary hospital from January 1, 2021, through January 1, 2022. Demographic data and chest wall deformity assessments were recorded at follow-up, including the anterior chest wall depths and depth ratio (DR). The demographic and clinical factors influencing treatment outcomes were tested using a logistic regression model.Results139 patients who accepted vacuum bell treatment were included in the final study analysis, with a mean age of 4.6 years and a BMI of 14.9. Forty-three patients (30.9%) with a depth of less than 3 mm met the termination criteria and showed cosmetic results. The changes in depths (P < 0.001) and DR (P < 0.001) were statistically significant in 55 patients with three or four follow-ups. Multifactor logistic regression analysis showed that initial depth (OR 0.69, 95% CI 0.58–0.84, P < 0.001) and treatment period (OR 1.58, 95% CI 1.23–2.04, P < 0.001) were independent predictors of achieving complete correction.ConclusionVB is an effective treatment modality in preschool patients in the short-term follow-up, which is influenced by the depth of depression and the duration of treatment. However, further prospective studies are needed to confirm these results.

“…Used as a non-surgical alternative to Nuss surgery, they were able to show that after an average of 11.1 months of therapy for 30 min 1.5 times a day, patients experienced significant improvement (z = −4.569, p < 0.001, 30 patients analyzed). Longer use showed better outcomes (R 2 = 0.235, p = 0.014) [ 36 ].…”

Medicine is a rapidly-evolving discipline, with progress picking up pace with each passing decade. This constant evolution results in the introduction of new tools and methods, which in turn occasionally leads to paradigm shifts across the affected medical fields. The following review attempts to showcase how 3D printing has begun to reshape and improve processes across various medical specialties and where it has the potential to make a significant impact. The current state-of-the-art, as well as real-life clinical applications of 3D printing, are reflected in the perspectives of specialists practicing in the selected disciplines, with a focus on pre-procedural planning, simulation (rehearsal) of non-routine procedures, and on medical education and training. A review of the latest multidisciplinary literature on the subject offers a general summary of the advances enabled by 3D printing. Numerous advantages and applications were found, such as gaining better insight into patient-specific anatomy, better pre-operative planning, mock simulated surgeries, simulation-based training and education, development of surgical guides and other tools, patient-specific implants, bioprinted organs or structures, and counseling of patients. It was evident that pre-procedural planning and rehearsing of unusual or difficult procedures and training of medical professionals in these procedures are extremely useful and transformative.

“…Custom-made devices tailored to the patient's anatomy are intended to make the application of brace and VB more comfortable thanks to greater ergonomics while continuing to ensure the effectiveness of the treatment. In this direction, in (Carfagni et al, 2018) and (Deng et al, 2020a(Deng et al, , 2020b was proposed a customization of the VB by designing it in a CAD environment directly on the patient's anatomy, whose 3 D geometry is obtained using Kinect Antonowicz et al (2016) proposed a process that allowed the creation of a custom compressive brace. The study was conducted starting with the 3 D scan of a healthy patient and creating a model that simulates the deformation caused by the PC.…”

“…Regarding studies that aimed to identify optical severity indices for the analysis of PE and PC, some focused on a single pathology, whereas others focused on both. With reference to PE, several studies (Poncet et al , 2007; Glinkowski et al , 2009; Lain et al , 2017; Bliss et al , 2019; Szafer et al , 2019; Taylor et al , 2019; Hebal et al , 2019; Scalabre et al , 2019; Deng et al , 2020a, 2020b, Daemen et al , 2021a, 2021b, 2021c, Fuentes et al , 2021; Guillot et al , 2021) proposed the adaptation of HI, which is commonly based on CT, to the external profile obtainable with optical scanners. These studies have proposed several new severity indices, which expand the definition of HI.…”

Purpose Among thoracic malformations, pectus deformities have the highest incidence and can result in a wide range of severe and mild clinical manifestations. Recently, the treatment of pectus deformities is shifting from traditional approaches toward customized solutions. This occurs by leveraging innovative rapid prototyping tools that allow for the design and fabrication of patient-specific treatments and medical devices. This paper aims to provide a comprehensive view of the growing literature in this area to analyze the progress made in this direction. Design/methodology/approach The search was performed on major search engines through keywords inherent to reverse engineering (RE) and additive manufacturing (AM) technologies applied to pectus deformities and related treatments, selecting 54 papers. These were analyzed according to the addressed pathology, the hardware and software tools used and/or implemented and their integration within the clinical pathway. Findings First, the analysis led to analyze and divide the papers according to how RE and AM technologies are applied for surgical and non-surgical treatments, pathological assessment and preoperative simulation and planning. Second, all papers were considered within the typical rapid prototyping framework consisting of the three phases of three-dimensional (3D) scanning, 3D modelling and 3D printing. Originality/value To the best of the authors’ knowledge, to date, no survey has provided a comprehensive view of innovative and personalized treatment strategies for thoracic malformations; the present work fills this gap, allowing researchers in this field to have access to the most promising findings on the treatment and evaluation of pathology.
