Submental intubation is an effective alternative technique for airway management in patients with maxillofacial trauma. Compared with tracheostomy, it is less invasive, but has risks associated with potential airway compromise such as hypoxia due to tube obstruction, collapse, and kinking. To shorten procedure time and ensure a reinforced tube lumen, we used a laparoscopic trocar as a new device for submental intubation. A 54-year-old male patient sustained a zygomaticomaxillary complex fracture and was scheduled to undergo open reduction and internal fixation. We performed intraoral intubation and made a small 1-cm incision at the submandibular midline. After dissection of the tissue from the incision site, a reinforced tube was passed using a 12-mm laparoscopic trocar. The procedure took about 5 minutes, and apnea time from disconnecting the breathing circuit and passing through the internal lumen of the trocar until it was reconnected to the ventilator was 1 minute 5 seconds. Using a laparoscopic trocar for submental intubation can reduce the time required for dissection, prevent luminal occlusion complications due to soft tissues or blood clots in the endotracheal tube, and decrease soft tissue damage.

The medical community has been heavily impacted by the coronavirus disease 2019 pandemic. The management of facial trauma patients has been affected by the patient capacity of emergency rooms. In this study, we share our experiences of facial trauma management during the social lockdown period and investigate the epidemiological changes in facial bone fractures.


A total of 997 patients who presented to Ajou University Hospital Emergency Center and were evaluated by plastic or maxillofacial surgeons for facial trauma were included in this retrospective study. Our study design was a comparative study of two groups: the 2019 group (control) and the 2020 group (the experimental group that experienced social lockdown).


The total number of emergency room inpatients reflected the national pandemic trends with three peaks in patient numbers. According to these trends, facial bone fractures had two different low points in August 2020 and December 2020. A comparison of the 2019 and 2020 facial bone fractures did not show a statistically significant difference in the total number of patients. An analysis of the causes of trauma showed that domestic accidents increased in 2020 (30.92%; p<0.001). Among the anatomical sites of facial injury in surgical patients, the frontozygomatic complex fracture increased the most in 2020 (p=0.018). Facial injuries with two separate sites of injury or with three or more involved sites also showed a significant increase in 2020 (p<0.001).


We demonstrated that the incidence of facial trauma patients correlated with the incidence of patients presenting to the emergency department and that facial trauma is inextricably related to multi-trauma cases. Domestic accidents and facial trauma with multiple anatomically involved sites are increasing trends that need more attention.
