Orbital fractures and concurrent ocular injury in a New Zealand tertiary centre.

Background: Orbital fractures are a common presentation to acute care and carry an associated risk of ocular injury, however, previous research has not investigated injury rates by fracture category. These patients are frequently assessed by non-ophthalmic clinicians, however, limited data exists regarding referral patterns and how this impacts recorded injury rates (1-3).

Methods: We performed a retrospective review of all orbital fractures presenting to a tertiary hospital in Christchurch, New Zealand between March 2019 and March 2021.

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.

Improved Outcomes of Orbital Reconstruction With Intraoperative Imaging and Rapid Prototyping.

Purpose: Rapid prototyping and intraoperative computed tomography (CT) are increasingly used in orbital reconstruction when placement of implants is indicated and accurate anatomic restoration is mandatory. The purpose of this study was to review the outcomes of orbital reconstructions at a single institution and the influence of intraoperative CT and rapid prototyping on the rate of return to the operating theater.

Materials And Methods: A retrospective cohort analysis was performed from 2013 through 2016 to assess whether rapid prototyping and intraoperative imaging were used and the need for further revision surgery.

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.

Bilateral submandibular salivary gland swelling--a report of chronic sialodochitis with eosinophilia.

A case of bilateral swelling of the submandibular salivary glands is presented. The histopathological features were diffuse periductal sclerosis with a lymphoplasmacytic infiltrate which was rich in eosinophils. Some acinar atrophy was seen.
