The use of the paramedian forehead flap alone or in combination with other techniques in the reconstruction of periocular defects and orbital exenterations

PURPOSE

The paramedian forehead flap (PMFF) is a reconstructive option for large eyelid defects and orbital exenterations. We report a series of cases where PMFF reconstruction was carried out at various institutions in Australia.

METHODS

This study was a multi-centre, retrospective, non-comparative case series investigating the clinical outcomes of the PMFF for reconstructing periocular defects and orbital exenterations.

RESULTS

This case series describes twenty-seven patients (Female = 15, Male = 12), operated between 1991 to 2019, with a median age of 81 years (range: 45-93 years). Defect locations involved combinations of the medial canthus (16/27, 59.3%), upper eyelids (7/27, 25.9%), lower eyelid (4/27, 14.8%), both upper and lower eyelids (5/27, 18.5%), and orbital (7/27, 25.9%). There were no cases of flap necrosis. Minor post-operative complications were observed in ten patients with the most common being lagophthalmos. Median duration of follow-up was 17months (Range: 2months- 23years).

CONCLUSIONS

The PMFF is a versatile reconstructive tool for a range of periocular defects and orbital exenterations with minor post-operative complications.

UNESCO Global Ethics Observatory: database on ethics related legislation and guidelines

The Database on Ethics Related Legislation and Guidelines was launched in March 2007 as the fourth database of the UNESCO Global Ethics Observatory system of databases in ethics of science and technology. The database offers a collection of legal instruments searchable by region, country, bioethical themes, legal categories and applicability to specific articles of the UNESCO Universal Declaration on Bioethics and Human Rights and International Declaration on Human Genetic Data. This paper discusses the background and rationale for the database and its role as a consultative and comparative resource hub for the study of ethics related legal instruments across the world, with the purpose of informing and inspiring relevant stakeholders on the implementation of the principles contained within the UNESCO declarations on bioethics.

Unesco's Global Ethics Observatory

The Global Ethics Observatory, launched by the United Nations Educational, Scientific, and Cultural Organization in December 2005, is a system of databases in the ethics of science and technology. It presents data on experts in ethics, on institutions (university departments and centres, commissions, councils and review boards, and societies and associations) and on teaching programmes in ethics. It has a global coverage and will be available in six major languages. Its aim is to facilitate the establishment of ethical infrastructures and international cooperation all around the world.
