This study aims to introduce a protocol of the fabrication of patient-specific, 3D printed and sterilizable auricular models for autogenous auricular reconstruction. (2) Methods: The patient\u2019s unaffected ear was captured with a high-resolution surface 3D scan (Artec Eva) and post-processed in order to obtain a clean surface model (STL format). In the next step, the ear was digitally mirrored, segmented and separated into its component auricle parts for reconstruction. It was disassembled into helix, antihelix, tragus and base and a physical model was 3D printed for each part. Following this segmentation, the cartilage was carved in the operating room, based on the models. (3) Results: This segmentation technique facilitates the modeling and carving of the scaffold, with adequate height, depth, width and thickness. This reduces both the surgical time and the amount of costal cartilage used. (4) Conclusions: This segmentation technique uses surface scanning and 3D printing to produce sterilizable and patient-specific 3D templates.<\/jats:p>","DOI":"10.3390\/jcm11133591","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T21:31:06Z","timestamp":1655933466000},"page":"3591","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Microtia Ear Reconstruction with Patient-Specific 3D Models\u2014A Segmentation Protocol"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5548-0302","authenticated-orcid":false,"given":"Juan","family":"Rodr\u00edguez-Arias","sequence":"first","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1324-9986","authenticated-orcid":false,"given":"Alessandro","family":"Guti\u00e9rrez Venturini","sequence":"additional","affiliation":[{"name":"Fundaci\u00f3n Para la Investigaci\u00f3n Biom\u00e9dica del Hospital Universitario La Paz, Calle de Pedro Rico 6, 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6269-4165","authenticated-orcid":false,"given":"Marta","family":"Pamp\u00edn Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"G\u00f3mez Garc\u00eda","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas","family":"Mu\u00f1oz Caro","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9467-0029","authenticated-orcid":false,"given":"Maria","family":"San Basilio","sequence":"additional","affiliation":[{"name":"Deparment of Pediatric Surgery, Hospital Universitario La Paz, Calle de Pedro Rico 6, 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mercedes","family":"Mart\u00edn P\u00e9rez","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6253-9800","authenticated-orcid":false,"given":"Jos\u00e9","family":"Cebri\u00e1n Carretero","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery Department, University Hospital La Paz, 28046 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"813","DOI":"10.1002\/bdra.20836","article-title":"Microtia-anotia: A global review of prevalence rates","volume":"91","author":"Luquetti","year":"2011","journal-title":"Birth Defects Res.
