Bone reconstruction represents a fundamental step that optimizes long-term aesthetic and functional outcomes. In recent years, 3D printing technology has also been exploited for complex skull base reconstructions, but reports remain scarce. Methods: We retrospectively analyzed four consecutive patients who underwent SOM resection and one-step 3D PEEK customized reconstruction from 2019 to 2023. A systematic review of 3D printing customized implants for SOM was then performed. Results: All patients underwent a frontotemporal craniotomy, removal of SOM, and reconstruction of the superolateral orbital wall and pterional region. The aesthetic outcome was extremely satisfactory in all cases. No orbital implant malposition or infectious complications were documented. Eleven papers were included in the literature review, describing 27 patients. Most (23) patients underwent a single-stage reconstruction; in three cases, the implant was positioned to correct postoperative delayed enophthalmos. Porous titanium was the most used material (16 patients), while PEEK was used in three cases. Prosthesis malposition was described in two (7.4%) patients. Conclusions: Single-step reconstruction with a personalized 3D PEEK prosthesis represents a valid reconstruction technique for the treatment of SOMs with good aesthetic outcomes.<\/jats:p>","DOI":"10.3390\/jcm13133968","type":"journal-article","created":{"date-parts":[[2024,7,8]],"date-time":"2024-07-08T09:01:19Z","timestamp":1720429279000},"page":"3968","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["3D Printing for Customized Bone Reconstruction in Spheno-Orbital Meningiomas: A Systematic Literature Review and Institutional Experience"],"prefix":"10.3390","volume":"13","author":[{"given":"Simona","family":"Serioli","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health, Spedali Civili of Brescia, University of Brescia, 25123 Brescia, Italy"},{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8745-4659","authenticated-orcid":false,"given":"Alberto","family":"Pietrantoni","sequence":"additional","affiliation":[{"name":"Pathology Unit, Spedali Civili of Brescia, University of Brescia, 25123 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2150-1213","authenticated-orcid":false,"given":"Alberto","family":"Benato","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4020-8883","authenticated-orcid":false,"given":"Marco","family":"Galeazzi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5360-5810","authenticated-orcid":false,"given":"Amedeo","family":"Piazza","sequence":"additional","affiliation":[{"name":"Neurosurgery Division, Department of Neuroscience, \u201cSapienza\u201d University of Rome, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6463-055X","authenticated-orcid":false,"given":"Liverana","family":"Lauretti","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"},{"name":"Neurosurgery, School of Medicine, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2857-9096","authenticated-orcid":false,"given":"Pier Paolo","family":"Mattogno","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Olivi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"},{"name":"Neurosurgery, School of Medicine, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4023-1909","authenticated-orcid":false,"given":"Marco Maria","family":"Fontanella","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health, Spedali Civili of Brescia, University of Brescia, 25123 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7438-0734","authenticated-orcid":false,"given":"Francesco","family":"Doglietto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"},{"name":"Neurosurgery, School of Medicine, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"268","DOI":"10.1007\/s10143-023-02178-y","article-title":"Reconstruction of orbital walls after resection of cranioorbital meningiomas: A systematic review and meta-analysis of individual patient data","volume":"46","author":"Lasunin","year":"2023","journal-title":"Neurosurg.
