Purpose:
The aim of this study was to evaluate surgical outcomes using patient-specific prostheses produced by computer-aided design and manufacturing for primary reconstruction in patients with benign cranio-orbital tumors. Polyetheretherketone was used to manufacture the implants.
Materials And Methods:
The present study included 3 patients who underwent fronto-orbito-pterional craniotomy using individual custom-made surgical guides. Patient-specific polyetheretherketone prostheses were used for reconstruction during the same surgery. All patients underwent esthetic examination (facial and orbital symmetry, globe projection and position), ophthalmologic examination (diplopia with the Hess-Lancaster test, visual field and acuity), and radiologic evaluations (computed tomography and magnetic resonance imaging) during the preoperative and follow-up periods. Operating time and short- and long-term complications were recorded.
Results:
The immediate and long-term morphologic results were satisfactory; in particular, ocular globe position and projection were correct. After 25 to 31 months, none of the patients developed implant-related complications, such as infection, extrusion, or malposition. Two-year postoperative computed tomograms and magnetic resonance images showed no recurrences.
Conclusion:
Single-step resection and reconstruction with computer-aided designed and manufactured implants is a challenging new technique that decreases operative time and morbidity. The implants adequately restore an anatomically complex area with satisfactory cosmetic results.
