Objective: Marginal mandibulectomy is a surgical procedure for treatment of mandibular gingival tumors. The intraoral approach to the posterior region of the mandible for marginal mandibulectomy is difficult due to limited access and operating field visibility; the conventional surgical procedure may require some skin incisions. This report discusses the effectiveness of endoscopic assistance in marginal mandibulectomy.

Methods: This article describes endoscopically assisted marginal mandibulectomy using an intraoral approach alone for squamous cell carcinoma of the posterior mandibular gingiva.

Results: The advantages of this surgical method are twofold: (1) superior visibility to the lower edge of the mandible without any skin incision; and (2) safe surgical confirmation of important anatomy on the buccolingual side (e.g., mental foramen, lingual nerve, mandibular foramen, and neurovascular bundle). This minimally invasive approach without any skin incision, as well as the superior visibility of the operating field, are important advantages of endoscopically assisted marginal mandibulectomy that cannot be obtained by other surgical methods.

Conclusions: Endoscopically assisted marginal mandibulectomy using an intraoral approach alone may be useful because it avoids damage to facial skin and improves safety by employing an enlarged bright field.

Study design: Cross-sectional study.

Objective: Childhood participation in boxing and martial arts has increased over the past decade, and these activities are well-known causes of traumatic injury. We hypothesized that the face is frequently injured in the setting of pediatric boxing and martial arts trauma in the United States and that there are identifiable injury patterns.

Methods: We performed a cross-sectional study of consecutive pediatric patients in the National Electronic Injury Surveillance System (NEISS) from January 1, 2010 to December 31, 2019. Patients were included in our study if they were younger than 18 years of age and evaluated in the emergency department (ED) after boxing or martial arts trauma. Primary outcome was facial injury. Other variables of interest include age, sex, ED disposition, type and location of injury. Descriptive and univariate statistics of the primary outcome were computed with these variables.

Results: There were 4,978 total pediatric patients injured due to boxing and martial arts trauma reported by NEISS-participating EDs during the study period, and 264 patients experienced injury to the face (264/4978; 5.3%). Over 20% (n = 60) of reported facial injuries were fractures; the most fractured structure was the nose (42/60; 70), orbit (11/60; 18.3%), and mandible (6/60; 10%). Almost 20% (11/60%) of pediatric facial fractures due to boxing and martial arts trauma involved fighting a family member or friend, and a punch was the most common mode of fracture (42/58; 72.4%).

Conclusions: Facial injuries comprise about 5% of injuries after boxing and martial arts trauma and 22% of these facial injuries are fractures. If children choose to participate, parents, coaches, trainers, officials, and community leaders should make the greatest effort possible to minimize risk, including the mandatory use of head and face protective gear and elimination of training fighting, or "sparring."

Study design: Retrospective study.

Objective: Zygomaticomaxillary complex (ZMC) fractures are common facial injuries with heterogeneity regarding aetiologies, fracture types, infraorbital nerve (ION) involvement, and treatment methods. The aim of this study was to identify associations between aetiologies, fracture types, and neurological complications. Additionally, treatment methods and recovery time were investigated.

Methods: Medical files of 272 patients with unilateral and bilateral ZMC fractures were reviewed, whose cases were managed from January 2014 to January 2019 at the Department of Oral and Maxillofacial Surgery, University hospitals Leuven, Belgium. History of ION sensory dysfunction and facial nerve motoric dysfunction were noted during follow-up.

Results: ION hypoaesthesia incidence was 37.3%, with the main causes being fall accidents, road traffic accidents, and interpersonal violence. Significant predictors of ION hypoaesthesia were Zingg type B fractures (P = 0.003), fracture line course through the infraorbital canal (P < .001), orbital floor fracture (P < 0.001), and ZMC dislocation or mobility (P = 0.001).

Conclusion: Of all ZMC fractures, 37.3% exhibited ION hypoaesthesia. Only ZMC Zingg type B fractures (74.0%) were significantly more associated with ION hypoaesthesia. ION hypoesthesia was more likely (OR = 2.707) when the fracture line course ran through the infraorbital canal, and was less dependent on the degree of displacement. Neuropathic pain symptoms developed after ZMC fractures in 2.2% patients, posing a treatment challenge. Neuropathic pain symptoms were slightly more common among women, and were associated only with type B or C fractures. No other parameters were found to predict the outcome of this post-traumatic neuropathic pain condition.

Study design: Retrospective cohort.

Objective: Traumatic facial fractures (FFs) often require specialty consultation with Plastic Surgery (PS) or Otolaryngology (ENT); however, referral patterns are often non-standardized and institution specific. Therefore, we sought to compare management patterns and outcomes between PS and ENT, hypothesizing no difference in operative rates, complications, or mortality.

Methods: We performed a retrospective analysis of patients with FFs at a single Level I trauma center from 2014 to 2017. Patients were compared by consulting service: PS vs. ENT. Chi-square and Mann-Whitney-U tests were performed.

Results: Of the 755 patients with FFs, 378 were consulted by PS and 377 by ENT. There was no difference in demographic data (P > 0.05). Patients managed by ENT received a longer mean course of antibiotics (9.4 vs 7.0 days, P = 0.008) and had a lower rate of open reduction internal fixation (ORIF) (9.8% vs. 15.3%, P = 0.017), compared to PS patients. No difference was observed in overall operative rate (15.1% vs. 19.8%), use of computed tomography (CT) imaging (99% vs. 99%), time to surgery (65 vs. 55 hours, P = 0.198), length of stay (LOS) (4 vs. 4 days), 30-day complication rate (10.6% vs. 7.1%), or mortality (4.5% vs. 2.6%) (all P > 0.05).

Conclusion: Our study demonstrated similar baseline characteristics, operative rates, complications, and mortality between FFs patients who had consultation by ENT and PS. This supports the practice of allowing both ENT and PS to care for trauma FFs patients, as there appears to be similar standardized care and outcomes. Future studies are needed to evaluate the generalizability of our findings.

Study design: This is a retrospective case series using the Thomson Reuters Westlaw Edge database, an online subscription-based database of over 40,000 state and federal records.

Objective: There is growing academic interest in the medical malpractice literature. The primary objective of this study was to examine medical malpractice in orthognathic procedures in order to characterize factors that determine legal responsibility and help make the craniomaxillofacial (CMF) surgeon more comfortable when treating this patient population.

Methods: The database was queried for medical malpractice cases involving orthognathic surgery from 1985-2021. The characteristics of each lawsuit were identified, and descriptive statistics were reported.

Results: A total of 42 CMF malpractice cases were available for review, and total of 15 cases were included in the final sample. Verdict decisions and settlements occurred between 1991 and 2012. Of the 15 cases, the highest concentration of cases occurred in California (6) and Pennsylvania (2). 53% of cases were ruled in favor of the defendant, 7% of cases were settled, 27% of cases were ruled in favor of the plaintiff against the surgeon, and 13% were ruled in favor of the plaintiff against the hospital with the surgeon being found not liable. The minimum award of damages was $29,999 and the maximum was $550,000.

Conclusion: Litigation experience can be very time consuming and troublesome for medical practitioners. The risk of litigation and complications might be a prohibiting factor as to why CMF surgeons may not be preforming orthognathic surgery. The best defense against a malpractice case is to avoid one altogether. Learning from past mistakes is one way of ensuring that goal.

Study design: Retrospective, observational, cross-sectional study.

Objective: To determine the incidence of skiing-related facial trauma and to identify their patterns in terms of potential risk factors, mechanism of injury, anatomical location, and degree of severity.

Methods: Data was collected using the National Electronic Injury Surveillance System and included snow skiing-related incidents during the years 2009 to 2018. Specifically, injuries limited to the facial region including the head, face, eye(s), mouth, neck or ear(s) were reported. Patients with fractures were further classified by the study variables. Descriptive statistics were used to classify continuous variables while chi-square analysis was used to compare categorical variables.

Results: A total of 514 (n = 514) patients met the inclusion criteria within the study period. The majority of injuries were due to concussions (59%), followed by lacerations (18%), fractures (11%), contusions (11%) and dental injuries (1%). Of the fractures seen, the majority were nasal (30%) and cervical spine (30%), followed by midface (27%), mandible (9%) and skull (4%). In our population, head injuries were more common in females (80%) than in males (60%), whereas, mouth injuries were more common in males (8%) than females (1%) [χ² = 30.2, p < 0.001].

Conclusions: Skiing-related craniofacial trauma remains a significant mechanism of injury. Our data illustrates a need to correlate these injuries to the use of personal protective equipment. Furthermore, this data calls for the strict implementation of such equipment and the development of safety protocols to further prevent deleterious injury.

Study design: This is a literature review with 3 case studies.

Objective: Intraoperative and postoperative bleeding are the most common complications of orthognathic surgery and have the potential to become life-threatening. The rarity of severe postoperative epistaxis has resulted in limited characterization of these cases in the literature. The purpose of this study is to 1) differentiate various presentations of epistaxis following orthognathic surgery in the literature, 2) identify management approaches, and 3) to synthesize a treatment algorithm to guide future management of postoperative epistaxis.

Methods: A literature search of PubMed was conducted and 28 cases from 17 studies were assessed.

Results: Bleeding within the first week may indicate isolated epistaxis, often resolved with local tamponade. Half of cases were attributed to pseudoaneurysm rupture (n = 14), with epistaxis onset ranging from postoperative day 6 to week 9. Angiography was used in most cases (n = 17), often as the primary imaging modality (n = 11). Nasal endoscopy is a less invasive and effective alternative to angiography with embolization. Proximal vessel ligation was used in 3 cases but is not preferred because collaterals may reconstitute flow through the defect and cause rebleeding. Repeat maxillary down-fracture with surgical exploration was described in 4 cases.

Conclusions: As outlined in our management algorithm, nasal packing and tamponade should be followed by either local electrocautery or vascular imaging. Angiography with embolization is the preferred approach to diagnosis and management, whereas surgical intervention is reserved for cases of embolization failure or unavailability.
