The Orbitomalar Ligament: A Cleavage Plane in Oculofacial Trauma.
Ophthalmic Plast Reconstr Surg
December 2024
We describe an oculofacial injury phenotype manifesting as a cleavage plane following the orbitomalar ligament in 5 cases. Across these cases, curvilinear wounds followed the course of the orbitomalar ligament, running clean planes through orbicularis oculi down to the infraorbital rim and arcus marginalis. One case involved bilateral orbitomalar ligaments, and 1 case involved the inferior canaliculus.

Article Synopsis
- The study focuses on primary periocular orofacial granulomatosis (PPOFG), a condition that causes swelling around the eyes, and aims to identify effective management strategies.
- A systematic review of 38 published cases, plus 9 local cases, showed that most patients primarily experience eyelid swelling, which tends to be bilateral, and symptoms like fissured tongue and facial nerve palsy are also common.
- Treatment options like surgical debulking and intralesional steroids have shown good short- and medium-term symptom relief for eyelid swelling, but no long-term cure exists, with recurrences being frequent.
Objective: To describe the manifestations and treatment of extraocular muscle (EOM) bacterial pyomyositis.
Design: A systematic review following PRISMA guidelines and a case report.
Methods: PubMed and MEDLINE databases were searched for case reports and case series of EOM pyomyositis using the term "extraocular muscle" combined "pyomyositis" and "abscess".
In the past few decades, minimally-invasive esthetic treatments and the use of injectable Hyaluronic Acid Gels and other filling agents to treat facial esthetics have increased dramatically. Although extremely rare, a filler can cause ocular and orbital ischemia by retrograde flow from the ophthalmic artery when injected in any of the anastomosis of the face. Once filler reaches the central retinal artery, blindness is inevitable, and no treatment is effective.

Methods: The point-of-view head camera captures the surgical field, while the point-of-view chest camera captures a wide field of view to record instrument ergonomics. Various methods of recording were trialed.
Case Report: A 67-year-old woman with a 30-year history of dysthyroid orbitopathy and diplopia had an inadvertent injection of botulinum toxin type A into the vitreous cavity. Full pupil mydriasis and an intraocular pressure (IOP) of 50 mm Hg in the right eye were noted after the injection. An attack of acute angle closure was initially suspected despite a patent peripheral iridotomy (PI).

- The study discusses a rare complication (restrictive strabismus and diplopia) related to the insertion of the Lester-Jones tube during conjunctivodacryocystorhinostomy, with previous reports only mentioning 4 cases.
- The researchers analyzed a series of 8 patients who experienced these symptoms at varying times (from months to 6 years post-insertion), with initial treatment involving topical steroids, and surgery to release adhesions when needed.
- Ultimately, only half of the patients treated (4 out of 8) achieved successful resolution of their diplopia, indicating that while treatment options exist, they are often ineffective.
Case Report: We report an incidence of basal cell carcinoma of the lower lid arising in an area of trauma 68 years after the initial injury.
Comments: Because patients may disregard the appearance of a wound in the setting of former trauma, medical practitioners need increased suspicion and surveillance of chronic nonhealing wounds.
