Silent Sinus Syndrome: A Case of Orbital Reconstruction With Patient-specific Implant and Intraoperative Navigation System and Computed Tomography Scan

By reporting a case of orbital restoration with a patient-specific implant (PSI), intraoperative navigation and computed tomography scan (CT) in a silent sinus syndrome patient, we aim to make reconstructive surgeons aware of the advantages these tools confer. We report a case of a 33-year-old woman affected by spontaneous enophthalmos and hypoglobus of her right eye. Anamnesis, physical exam and CT findings were compatible with a silent sinus syndrome. Caldwell-Luc technique and concurrent transconjunctival repair of the orbital floor using a PSI with intraoperative navigation and CT scan were performed successfully, achieving satisfactory repositioning of the globe and facial symmetry. The silent sinus syndrome is an acquired uncommon condition which may require correction of secondary orbital deformities. In this scenario, patient-specific implants, CAD/CAM and intraoperative navigation have emerged as safe and effective tools.
