Spear gun projectiles injuries are are very rare and are usually related to lack of attention during water- sports or fishing practices. This study aims to describe an unusual case of facial injury associated with a mandibular fracture after a spear gun shot. A 38-years-old man was admitted with a history of penetrating injury on the face caused by an accidental shot from a spear gun. After the initial stabilization and examination, the patient was taken to the surgical room for the removal of the projectile. The post-operative care was uneventful and the patient was discharged with no concerns, being in follow-up for one year with no signs of infection or malocclusion. The surgical procedure should be done as soon as possible and the removal of the spear must be done carefully, under direct vision, with or without surgical incisions. Major complications can occur after spear injuries, therefore, the patient must be observed in the postoperative period and should maintain follow up until the end of the rehabilitative process.

The incisions during orthognathic surgery are classically performed with conventional scalpel or electrocautery. Considering that the high-power diode laser surgery may provide advantages when compared to conventional incision techniques, the current study aimed to present a prospective case series of patients submitted to circumvestibular incision for Le Fort I osteotomy. Ten patients with dentofacial deformities who underwent to rapid assisted maxillary expansion or bimaxillary orthognathic surgery were enrolled in the study. All incisions were performed by a single surgeon using an 808-nm diode laser, with an optical fiber of 600 μm, at a power of 2.5 W, in a continuous-wave mode. The performance of the incision was evaluated by incision velocity, bleeding, edema, secondary infection, clinical healing, and pain. The velocity of the incision ranged from 0.10 to 0.20 mm/s (mean 0.13 ± 0.03 mm/s). Considering bleeding during the soft tissue incision, all surgeries were classified as absent bleeding. All patients presented a clinical healing of the surgical wound in a period that range from 3 to 5 weeks and experienced swelling during the follow-up period. On average, approximately 50% of the swelling had resolved after the third postoperative week, and 28.8% of swelling remained after 2 months after the surgery. The pain decreased after 2 and 3 days, and 90.0% of the patients reported no pain after 7 postoperative days. High-power diode laser is effective and safety during circumvestibular incisions for Le Fort I osteotomy in orthognathic surgery decreasing bleeding, surgery time, pain, and edema after orthognathic surgery.

Abstract: The pandemic status of the Novel Coronavirus 2019 has affected many countries around the world, due to the high virulence of the SARS-CoV-2, the recommended protocol to prevent infection is social isolation. The purpose of this study was to compare the number of patients admitted and their epidemiological data on a Level 1 Trauma Hospital after the declaration of the pandemic status and the first week of mandatory lockdown, with the same period of time in the last year. This was a retrospective study of medical records from the patients admitted in the Oral and Maxillofacial Surgery of the João XXIII Hospital, between the March 24 and March 31 of 2020 and the same period of the last year. There was a 52.27% decrease in the total number of patients and 76.34% decrease in the total consultations of the service of oral and maxillofacial surgery during the lockdown. All the groups presented a decrease in significance with motor vehicle accidents events, the group 11 to 20 years old presented an increase on the correlation with violence (P = 0.019) and falls (P = 0.002). When comparing both sex with the etiologies, the male one presented an increase in the correlation with violence and falls. The female sex presented correlations only with the minor causes. No valid significance was observed when comparing females with violence events. The lockdown is an effective way to reduce the transmission of the COVID-19, the hospital usage and occupation., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by Mutaz B.
