Orbital trapdoor fractures are characterized by tissue entrapment between the fractured bone fragment and the remnant of the orbital floor. This entrapment can result in immediate local and systemic complications and poor outcomes when approached late. This article presents the case of an orbital floor fracture in a child with dystopia, pain, edema and entrapment of the inferior rectus muscle and consequent limitation of ocular motility. The strategy proposed in the early approach to orbital floor reconstruction and release of incarcerated tissue allowed the patient to achieve satisfactory results without morbidity, as compared to the outcomes of corrective sequel surgery.

Introduction: Orbital fractures are common among maxillofacial injuries. The primary objective of this study was to investigate the clinical and radiographic characteristics of pure orbital blowout fractures (OBFs) and their association with post-traumatic diplopia. The secondary objective was to identify predictors of diplopia in pure OBFs.

Purpose: To define the anatomical variance between orbital floor and medial orbital wall blowout fractures, and its change with age.
Methods: This was a retrospective, observational study analyzing data from 557 patients with isolated blowout fractures of the orbital floor or medial orbital wall. Axial and quasi-sagittal CT images were analyzed to compare radiologic data on orbital wall morphology between fracture site groups and among age groups.
Objective: Evaluate the feasibility of the midface degloving approach (MDA) in total maxillectomy without orbital exenteration (TMWOE) and reconstruction for sino-nasal neoplasms.
Study Design: Retrospective case series.
Setting: Tertiary referral center.
A Novel Classification System for the Anatomical Variations of the Infraorbital Ethmoidal (Haller) Air Cells.

Article Synopsis
- Infraorbital ethmoidal air cells (IOEAc) are a type of ethmoidal cells located beneath the orbit, showing significant anatomical variation in humans.
- A study involving 1260 CT scans aimed to identify and classify these variations, noting the presence of IOEAc in 173 cases (13.7%).
- The new classification system categorized the air cells into five main types with various subtypes, enhancing understanding for clinical practice and future research.

CT is the gold standard for evaluating orbital trauma, providing rapid and detailed imaging of bony structures, soft tissue, and the globe. This is crucial in assessing orbital trauma due to its potential to cause significant impairment of ocular function. This case report presents a 35-year-old male who was admitted to the emergency department with a complicated left orbital blow-out fracture following blunt facial trauma.
