The orbit\u2019s volume can be restored surgically. The authors aimed to determine the most accurate and cost-effective method for reconstructing blow-out fractures: virtual surgical planning (VSP) combined with patient-specific implants (PSI) or standard titanium stock implants. \nMaterials and methods: The authors conducted a retrospective study of patients who sustained a blow-out fracture requiring surgical reconstruction. Patients were categorized into two groups: the PSI group (n = 13) and the standard titanium stock implant group (n = 36). The primary aim was to analyze the total cost in each group, with a secondary aim to ensure volumetric restoration was achieved. Postoperative volume, operation time, need for reoperation, surgical and inpatient costs, and cost-effectiveness were calculated. The data were analyzed with Shapiro\u2013Wilk, Mann\u2013Whitney U test, and Fisher\u2019s exact test, using a significance level of 0.05. \nResults: The operation time was significantly shorter in the PSI group than in the stock implant group, with an average of 89.77 and 122.69 min, respectively (p = 0.008), resulting in lower total costs in the PSI group. The PSI group had better postoperative volumetric restoration than the stock implant group compared to the contralateral side (p = 0.01). Four out of 36 patients (11%) needed reoperation in the stock implant group. Conclusions: Preliminary results suggest that PSI requires a shorter operation time and is therefore cost-effective without compromising surgical outcomes.<\/jats:p>","DOI":"10.2340\/jphs.v61.46676","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T08:05:38Z","timestamp":1792137938000},"page":"243-248","source":"Crossref","is-referenced-by-count":0,"title":["Patient-specific implants are accurate and cost-effective for blow-out fracture reconstruction: a retrospective case-control study"],"prefix":"10.2340","volume":"61","author":[{"given":"Eeva","family":"Kormi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ville","family":"M\u00e4nnist\u00f6","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pilvi","family":"M\u00e4ntynen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niilo","family":"Lusila","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juho","family":"Suojanen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2026,10,16]]},"reference":[{"key":"171283","doi-asserted-by":"crossref","unstructured":"Patel S, Shokri T, Ziai K, et al.
