Computed tomographic (CT) data were used to design a PSI replicating the inner surface of the unfractured orbit. The data were converted to an STL file and 3D\u2010printed using polylactic acid (PLA) filament. Surgical access was obtained via a concho\u2010frontal sinus flap combined with sinoscopy. To reconstruct and seal the orbit, the PSI was lined with porcine small intestinal submucosa and secured to the inner orbital wall using two 3.0\u2009mm titanium locking screws and synthetic, non\u2010absorbable transosseous fiber loops.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The emphysema resolved postoperatively, and ocular function was unrestricted by the implant. Infection developed subcutaneously adjacent to the transosseous suture fixation at the maxillary bone but resolved with conservative management. Follow\u2010up CT at 11\u2009weeks and owner reports after 18\u2009months confirmed a favorable cosmetic and functional outcome, with only minimal residual ptosis of the left upper eyelid.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Application of a PSI axially to the left orbit successfully reconstructed the orbital wall and resolved the communication with the caudal maxillary sinus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical significance<\/jats:title>\n                    <jats:p>Patient\u2010specific implants represent a novel surgical option for the repair of complex orbital wall fractures in horses.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/vsu.70050","type":"journal-article","created":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T10:36:27Z","timestamp":1761820587000},"page":"920-928","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reconstruction of an orbital fracture in a mare using a\n                    <scp>3D<\/scp>\n                    \u2010printed patient\u2010specific implant"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3652-3321","authenticated-orcid":false,"given":"Jennifer","family":"Gernhardt","sequence":"first","affiliation":[{"name":"Equine Clinic, Freie Universit\u00e4t Berlin  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"B\u00f6ttcher","sequence":"additional","affiliation":[{"name":"Small Animal Clinic, Freie Universit\u00e4t Berlin  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
