Head and Neck Injuries Associated With Cell Phone Use

Importance

As cell phones gain more influence in daily life, they also become potentially more hazardous. Injuries resulting from cell phone use have long been reported largely in the context of driving-related incidents, but other mechanisms of injury have been underreported.

Objective

To assess the incidence, types, and mechanisms of head and neck injuries associated with cell phone use.

Design, Setting, and Participants

Retrospective cross-sectional study using data from a national database of individuals with head and neck injuries related to cell phone use who presented to emergency departments in the United States between January 1998 and December 2017.

Main Outcomes and Measures

Incidence, types, and mechanisms of injury related to cell phone use in the US population.

Results

A reported total of 2501 patients (1129 [55.0%] female, 795 [38.8%] white, and 772 [37.6%] aged 13-29 years) presented with injuries of the head and neck related to cell phone use; the estimated weighted national total was 76 043 patients (42 846 females [56.3%], 34 894 [45.9%] white, and 29 956 [39.4%] aged 13-29 years). The most commonly reported subsites of injuries in the head and neck region included the head (33.1% of estimated total); face, including eyelid, eye area, and nose (32.7%); and neck (12.5%). The most common injury diagnoses included laceration (26.3% of estimated total), contusion/abrasion (24.5%), and internal organ injury (18.4%). Age group distributions showed that most injuries associated with cell phone user distraction occurred among individuals aged 13 to 29 years (60.3%; Cramer V = 0.29). In addition, those younger than 13 years were significantly more likely to sustain direct mechanical injury from a cell phone (82.1%) than to have a cell phone use-associated injury (17.9%) (Cramer V = 0.305), whereas a cell phone use-associated injury was more likely than a direct mechanical injury to occur among those aged 50 to 64 years (68.2% vs 31.8%; Cramer V = 0.11) and those older than 65 years (90.3% vs 9.7%; Cramer V = 0.29).

Conclusions and Relevance

Cell phone-related injuries to the head and neck have increased steeply over the recent 20-year period, with many cases resulting from distraction. Although the disposition of most cases is simple, some injuries bear a risk of long-term complications. Many of these injuries occurred among those aged 13 to 29 years and were associated with common activities, such as texting while walking. These findings suggest a need for patient education about injury prevention and the dangers of activity while using these devices.

Validation of virtual reality orbitometry bridges digital and physical worlds

Clinical science and medical imaging technology are traditionally displayed in two dimensions (2D) on a computer monitor. In contrast, three-dimensional (3D) virtual reality (VR) expands the realm of 2D image visualization, enabling an immersive VR experience with unhindered spatial interaction by the user. Thus far, analysis of data extracted from VR applications was mainly qualitative. In this study, we enhance VR and provide evidence for quantitative VR research by validating digital VR display of computed tomography (CT) data of the orbit. Volumetric CT data were transferred and rendered into a VR environment. Subsequently, seven graders performed repeated and blinded diameter measurements. The intergrader variability of the measurements in VR was much lower compared to measurements in the physical world and measurements were reasonably consistent with their corresponding elements in the real context. The overall VR measurements were 5.49% higher. As such, this study attests the ability of VR to provide similar quantitative data alongside the added benefit of VR interfaces. VR entails a lot of potential for the future research in ophthalmology and beyond in any scientific field that uses three-dimensional data.
