Background And ObjectivesDecompressive craniectomy (DC) is a commonly performed procedure to alleviate high intracranial pressure. To enhance patient quality of life and minimize complications after DC in patients awaiting cranioplasty (CP), multidisciplinary teams have designed and implemented external protective prototypes, including 3-dimensional printing and plaster models, whenever feasible. The aim of this scoping review was to assess the evidence available on innovative external cranial devices that protect the craniectomy site for patients who have undergone DC while awaiting CP in high-income countries and low- and middle-income countries.MethodsThis scoping review was conducted following the methodology outlined by the Joanna Briggs Institute. Searches were performed in databases such as MEDLINE, Embase, Web of Science, Scielo, Scopus, and World Health Organization Global Health Index Medicus. Patent documents were also searched in Espacenet, Google Patents, and World Intellectual Property Organization. This scoping review included external protective devices for adult patients who underwent DC and CP, while invasive devices were excluded.ResultsA total of 9 documents described external cranial devices, with 7 of them led by researchers from high-income countries, including the United States (n = 4), Singapore (n = 1), the United Kingdom (n = 1), and Hong Kong SAR, China (n = 1). Among these devices, 77.7% (n = 7) were created using 3-dimensional printing, while 22.3% (n = 2) were developed through plaster hand modeling. The individual study results were summarized.ConclusionSustainable Development Goal (SDG) 3, SDG 9, and SDG 10 play a crucial role in the advancement of innovative strategies to ensure access to essential neurosurgical care, reduce global disparities in treatment outcomes, mitigate postoperative complications, and provide life-saving interventions. This scoping review provides fundamental evidence for multidisciplinary teams involved in designing noninvasive innovations to minimize the risks associated with post-DC complications. It is anticipated that more cost-effective models, particularly in low- and middle-income countries, can be implemented based on the findings of this review.Copyright © Congress of Neurological Surgeons 2024.
