Article Synopsis
  • The study investigates the factors and outcomes related to surgical treatment of rare frontal and naso-orbito-ethmoidal (NOE) fractures at two Australian hospitals over six years.
  • A total of 60 patients, predominantly male, were analyzed, with traffic accidents being the leading cause of these injuries and a significant percentage exhibiting associated brain injuries.
  • Results indicated a notable postoperative complication rate (around 39% for frontal and 38% for NOE fractures), highlighting the need for further research to enhance understanding and patient outcomes in this area of trauma surgery.

Objective: Naso-orbito-ethmoidal fractures (NOE) fractures are uncommon but critical injuries. This review aims to investigate the patient factors, procedural factors, and postoperative outcomes associated with the surgical management of NOE fractures.

Study Design: PubMed and Scopus databases were systematically searched between 1993 and 2023 using the search strategy "(naso-orbito-ethmoidal OR nasoethmoid OR nasoorbitoethmoidal) AND fracture.

Study Design: Systematic review.

Objective: Standing electric scooters (e-scooters) provide a cheap and environmentally friendly transport alternative, but also elicit substantial concern regarding their volume of associated injuries especially in the craniofacial region. This review aims to explore the demographics, risk factors, types of injury and surgical management of craniofacial trauma associated with e-scooters.

Background: Fractures involving the bilateral mandibular angle are an uncommon occurrence with limited evidence to inform the ideal fixation requirements for adequate treatment. The aim of this study was to evaluate the outcomes of managing bilateral mandibular angle fractures and determine whether rigid fixation on 1 side improves outcomes compared with bilateral nonrigid fixation.

Methods: Patients with isolated bilateral mandibular angle fractures treated surgically at the Royal Brisbane and Women's Hospital, Princess Alexandra Hospital, Gold Coast University Hospital, and Townsville University Hospital between January 1, 2010, and December 31, 2022, were identified retrospectively.

Patients undergoing radiotherapy for head and neck cancers are prone to a range of dental complications, including mucositis, trismus, xerostomia, radiation caries and osteoradionecrosis. Specific considerations include the preventive, restorative and rehabilitative management of such patients, and the prevention and treatment of complications. This article aims to highlight the current understanding and management of dental needs for patients who have had or will undergo radiotherapy.

Purpose: Orbital volume increase has been previously linked with post-traumatic enophthalmos. However, this varies and some studies show no correlation. This systematic review and meta-analysis aimed to synthesize the correlation between orbital volume and enophthalmos and to determine if surgical intervention, enophthalmos measurement method, fracture location, or timing affect this correlation.

Purpose/objectives: Dental anxiety is common and can propagate a vicious cycle of dental neglect and anxiety-provoking treatment. Patient, procedural, and operator factors are important contributions. This review aims to explore risk factors for dental anxiety in adult patients treated by dental students, in order to improve awareness of relevant factors and aid patient management.

Our aim was to evaluate ophthalmological injuries associated with fractures of the orbitozygomaticomaxillary complex that required operative treatment, and we collected data retrospectively over a period of five years (2012-2016 inclusive). Of the 190 patients, 162 were male with a median age of 31 (IQR 25 -39) years. Assault was the most common mechanism of injury (125/190, 66%).
