Abstract

Objectives: Personal mobility devices (PMDs) have become an increasingly popular transport in South Korea. With increasing the number of users of PMDs, which provide quick and convenient mobility options, the number of individuals visiting emergency departments with PMD-related facial injuries has also increased annually. This report aims to raise awareness of the risk of PMDs by presenting cases of facial injury related to PMDs that has recently occurred.
Materials and Methods: In this report, patients who came to our hospital, Wonju Severance Christian Hospital, with PMD-
related injuries were described from June to August 2022. A total of 11 patients visited the hospital, and four of them were reported as cases. Patients underwent general anesthesia to conquer the fractured facial bone and teeth. CT or panoramic photographs were presented before and after surgery.
Results: All four patients underwent open reduction and internal fixation (ORIF) surgery under general anesthesia, and the boxing with rubber or wire was maintained for 2?3 weeks using the intermaxillary fixation (IMF) system after surgery. Compared to before surgery, facial width, hight and function was restored, and proper occlusion was obtained. The patient
who had the injured teeth fixed with resin wire splint (RWS) obtained good fixation and proceeded with endodontic treatment. Patients with infra-orbital nerve and mental nerve damage are also recovering.
Conclusion: As shown in the above cases, facial injuries caused by PMDs, electric scooters, often accompany facial complex fractures, condylar fractures, and alveolar fractures with dental injuries rather than simple fractures of the mandible and maxilla. Although it has the great advantage of being able to move quickly and conveniently over long distances, it is more easily exposed to trauma, and often accompanied by more serious facial damages. There is a need for stricter regulations regarding the use of PMDs, advocating the use of protective equipment, and raising awareness of the consequences and safety measures of PMD-related accidents.
