BackgroundAn orbital implant is used after enucleation or evisceration surgery to replace the volume lost and to aid in prosthesis fitting and movement. Different materials have been used through the years. The authors noted that with bone-derived hydroxyapatite orbital implants, some patients lose their orbital volume.MethodsThe operating theatre record was searched to find patients who had their hydroxyapatite orbital implant removed at Dunedin Hospital, New Zealand, between 2011 and 2015. The original implant size and size at removal were noted. Histological results were noted. Medical notes were reviewed.ResultsA total of six patients had hydroxyapatite orbital implants removed during this time. Four patients had implants that were smaller than their original sizes. All specimens had fibrovascular infiltration noted, three had chronic inflammatory cells and one had osteoclastic activity.ConclusionsBone-derived hydroxyapatite orbital implants can reduce in size, and this may occur due to osteoclastic activity. The surgeon must consider this scenario when choosing the type of implant to be used after enucleation or evisceration.

Abstract Background Protective funnels devices are commonly used to deliver implants in primary breast augmentation (BA) yet there is a paucity of evidence-based data describing their safety in the literature. Objectives The purpose of the study was to assess the safety of protective funnels in primary BA within the first 30-days postoperatively. Methods This multi-center, Level 3 study retrospectively reviewed the surgical records of 380 consecutive patients (760 breasts) who underwent primary BA by nine board-certified plastic surgeons using the iNPLANT Funnel (Proximate Concepts LLC, Allendale, NJ, USA) for implant delivery between November 2019 and December 2020. Data was collected pertaining to demographics, implant information, surgery details, and postoperative complications. Results The mean patient age was 33 years and 76% patients had a BMI < 25. Of this cohort, 11.4% were smokers, 0.8% had diabetes, and 83% were ASA class 1. All patients received smooth implants with a median volume of 375cc. A total of 8 (2.1%) complications were reported including: 3 hematomas (0.79%), 1 seroma (0.26%) and 1 superficial infection (0.26%). No patient required explantation. We identified ASA class, BMI, surgery duration, and implant size as potential risk factors. Conclusions The data suggest that use of protective funnels, such as the iNPLANT Funnel, in primary BA are a safe option when used according to the manufacturer’s IFU. Its use led to a low infection rate (0.26%) and a complication rate (2.1%) consistent with the average reported in the literature (2%-2.5%). 1 Implications for clinical practice are encouraging and future research will include a prospective analysis with a larger case series and potentially a control group.

Objectives: High-quality research is fundamental to the advancement of surgical practice. Currently, there is no quantitative assessment of the research output of vascular surgeons in Australia and New Zealand. By conducting this bibliometric analysis, we aim to provide an objective representation of the trends in vascular surgery and guide future research. Methods: A list of all current vascular surgeons in Australia and New Zealand was compiled from the Royal Australasian College of Surgeons ‘Find a Surgeon’ website tool and correlated with the Australia and New Zealand Society for Vascular Surgery database. A Scopus search of each surgeon’s author profile over the last 20 years was conducted. Results: In total, 2120 articles were published by 208 Australasian vascular surgeons between 1998 and July 2018, with an overall increase in publications over time. Audits or case series were the most published type of study and only 8% of the publications were of high-level evidence. The most popular topics were thoracoabdominal aortic pathologies (24%), followed by peripheral arterial disease (15%). Chronological analysis illustrates an increasing volume of peripheral arterial disease research over time and there is a clear trend towards more endovascular and hybrid surgery publications. The top 10 (5%) highest publishing authors by h-index account for 41% of all publications and 49% of all citations and are also responsible for producing significantly more high-level evidence research. Conclusion: Australasian vascular surgeons have made a significant contribution to medical research. However, the majority of these articles are of low-level evidence. In this time, there has been an increasing number of publications on endovascular and hybrid surgery in keeping with the trend in clinical practice. These areas, as well as research regarding peripheral arterial disease, show potential for high-evidence research in the future.

AbstractOrbital and craniomaxillofacial defects, in general, are best approached preoperatively by a multidisciplinary team with a clear reconstructive plan in place. Orbital defects result from a myriad of underlying diseases and injuries, and reconstruction after orbital evisceration, enucleation, or exenteration can pose a challenge to the reconstructive team. Reconstruction of orbital injuries with orbital implants and prostheses can lead to acceptable aesthetic outcomes, and the reconstructive surgeon should be familiar with current orbital implants and prostheses. Herein, the authors review terminology and classifications of orbital defects, different types of orbital implants, advantages and disadvantages of different orbital implant reconstructive options, types of orbital prostheses, and pros and cons of different prosthetic options.

AbstractObjectives:To evaluate common pitfalls in diagnosing complicated plunging ranula, either due to misidentification of plunging ranula or alternative pathology (i.e. false negatives or false positives, respectively).Methods:A review of cases of plunging ranula seen in Middlemore Hospital, New Zealand, was performed. Diagnostically uncertain cases were identified and reviewed, taking particular note of clinical, radiological and surgical findings.Results:From our database, 12 cases were found to have had a complicated diagnosis of plunging ranula. Ten cases were false negatives: four were treated as abscesses, four as simple cysts, one as a thyroglossal cyst and one as a cystic hygroma. Two cases were false positives: one was found to be a thyroglossal cyst and the other a lipoma.Conclusion:The diagnosis of plunging ranula is usually straightforward, with simple surgical management. Misdiagnosis can lead to recurrence of symptoms and inappropriate management, with the associated risks, complications and frustrations of surgery.
