Autologous grafts have limited tissue availability and can cause significant donor-site morbidity, homologous grafts often require immunosuppression, and alloplastic grafts may have high rates of infection or displacement. Furthermore, all these grafting techniques require a high level of surgical skill to ensure that the reconstruction matches the original structure. Current research indicates that additive manufacturing shows promise in overcoming these limitations. Autologous stem cells have been developed into cartilage when exposed to the appropriate growth factors and culture conditions, such as mechanical stress and oxygen deprivation. Additive manufacturing allows for increased precision when engineering scaffolds for stem cell cultures. Fine control over the porosity and structure of a material ensures adequate cell adhesion and fit between the graft and the defect. Several recent tissue engineering studies have focused on the trachea, nose, and ear, as these structures are often damaged by congenital conditions, trauma, and malignancy. This article reviews the limitations of current reconstructive techniques and the new developments in additive manufacturing for tracheal, nasal, and auricular cartilages.<\/jats:p>","DOI":"10.3390\/biomimetics9060327","type":"journal-article","created":{"date-parts":[[2024,5,29]],"date-time":"2024-05-29T06:58:07Z","timestamp":1716965887000},"page":"327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Contemporary Review of Trachea, Nose, and Ear Cartilage Bioengineering and Additive Manufacturing"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7042-6213","authenticated-orcid":false,"given":"Max","family":"Feng","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Loma Linda University Medical Center, Loma Linda, CA 92354, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khwaja Hamzah","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Loma Linda University Medical Center, Loma Linda, CA 92354, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nihal","family":"Punjabi","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Loma Linda University Medical Center, Loma Linda, CA 92354, USA"},{"name":"School of Medicine, Case Western Reserve University, Cleveland, OH 44116, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jared C.","family":"Inman","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Loma Linda University Medical Center, Loma Linda, CA 92354, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1159\/000456691","article-title":"Laryngeal Transplantation","volume":"Volume 85","author":"Bewley","year":"2020","journal-title":"Advances in Oto-Rhino-Laryngology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"568","DOI":"10.1097\/MOT.0000000000000812","article-title":"The past the present and the future of face transplantation","volume":"25","author":"Siemionow","year":"2020","journal-title":"Curr.
