A Literature Review of Rapid Prototyping and Patient Specific Implants for the Treatment of Orbital Fractures.

Post-traumatic reconstruction of the orbit can pose a challenge due to inherent intraoperative problems. Intra-orbital adipose tissue is difficult to manipulate and retract making visualization of the posterior orbital contents difficult. Rapid prototyping (RP) is a cost-effective method of anatomical model production allowing the surgeon to produce a patient specific implant (PSI) which can be pre-surgically adapted to the orbital defect with exact reconstruction.

A case series of rapid prototyping and intraoperative imaging in orbital reconstruction.

In Christchurch Hospital, rapid prototyping (RP) and intraoperative imaging are the standard of care in orbital trauma and has been used since February 2013. RP allows the fabrication of an anatomical model to visualize complex anatomical structures which is dimensionally accurate and cost effective. This assists diagnosis, planning, and preoperative implant adaptation for orbital reconstruction.

Rapid prototyping technology in orbital floor reconstruction: application in three patients.

Rapid prototyping entails the fabrication of three-dimensional anatomical models which provide an accurate and cost-effective method to visualize complex anatomical structures. Our unit has been using this to assist in the diagnosis, planning, and preoperative titanium plate adaptation for orbital reconstruction surgery following traumatic injury. The aim of this article is to demonstrate the potential clinical and cost-saving benefits of this technology.

Incidental maxillary sinus findings in patients referred for head and neck CT angiography.

Background: Maxillary sinus pathology is a common finding on routine CT scans of the head and neck. The purpose of this study was to assess the incidental findings in the maxillary sinus on CT scans in patients who presented for head and neck CT angiography.

Study Design: Images of patients referred for head and neck CT angiography were reviewed over a 5-month period.
