Lower Eyelid Surgical Anatomy and the Implications for Blepharoplasty Surgery: A Systematic Review of Anatomic Studies in the Literature.

Lower eyelid blepharoplasty is a procedure to address issues arising from age-related anatomic changes of the lower eyelid. These include excess skin, fat herniation, tear trough hollowing, and midface descent. Unlike the well-defined structures of the upper eyelid, the lower eyelid's anatomy, including the retractors and surrounding ligaments, is less distinct and understudied.

The Posthyaluronidase Syndrome: Dosing Strategies for Hyaluronidase in the Dissolving of Facial Filler and Independent Predictors of Poor Outcomes.

Background: Hyaluronic acid dermal fillers are used extensively in periocular aesthetic medicine, and the incidence of filler-related complications is increasing. This study aimed to investigate the optimal dosing strategy for hyaluronidase and to identify predictors of poor outcomes.

Methods: We performed a retrospective review of 157 orbits of 90 patients treated with hyaluronidase over a 4-year period.

Tear Trough Filler Using the Three-point Tangent Technique: Lessons from 1452 Tear Trough Applications.

Unlabelled: This study describes a novel three-point tangent technique for tear trough filler and the results from the largest series to date.

Methods: A retrospective case review was performed for all patients treated between 2016 and 2020. Patient demographics, filler details and complications were recorded.

Orbital compartment syndrome following tear trough filler injection.

A patient was treated with tear trough filler and developed a retrobulbar haemorrhage. This was managed acutely with a lateral canthotomy and cantholysis with no lasting visual compromise. This is the first reported case of an orbital compartment syndrome following filler injection and highlights the potential blinding complications which can occur.

Corneal Neurotization Using the Great Auricular Nerve for Bilateral Congenital Trigeminal Anesthesia.

Purpose: The purpose of this study was to describe an indirect corneal neurotization (CN) technique for congenital bilateral trigeminal anesthesia using the greater auricular nerve (GAN) as a donor.

Method: CN was performed to preserve the integrity of the only seeing eye in a 4-year-old boy with pontine tegmental cap dysplasia and bilateral trigeminal anesthesia. He had recurrent corneal ulceration and scarring despite full medical treatment.
