STUDY DESIGN: A retrospective review was conducted of all patients with mandibular fractures who were evaluated by plastic surgery at a Level I trauma center between January 1, 2017 and May 1, 2020. Data including demographic characteristics, mechanism of injury, type of presentation (e.g., primary or transfer), treatment plan, and time to intervention were recorded. OBJECTIVE: Mandibular fractures are common traumatic injuries. Because these injuries are managed by surgical specialists, these patients are often emergently transferred to tertiary care hospitals...

STUDY DESIGN: Review of the literature with report of Case. OBJECTIVE: To review the presentation of Actinomycosis specifically as it occurs with mandibular osteotomies. METHODS: A review of the literature and report of an additional case. RESULTS: While minor infections secondary to local factors are usually seen 2-3 weeks after surgery, late infections are rare. Host factors may play a role. When actinomycosis is diagnosed, long-term antibiotics are necessary...

STUDY DESIGN: Case series. OBJECTIVE: This retrospective review of frontal sinus fractures aims to describe our current experience managing these fractures at an urban level I trauma center. METHODS: An institutional database of 2081 patients who presented with maxillofacial fractures on computed tomography face/sinus in 2019 was queried for all patients with traumatic frontal sinus fractures. Demographics, trauma-related history, management approach, and follow-up data were collected and analyzed...

STUDY DESIGN: Retrospective Observational Study. OBJECTIVE: Mandibular condyle fractures are distinctive among maxillofacial injuries in which they disrupt mandibular function in a way that other traumatic injuries do not. Condylar fractures can be treated using either the conservative (closed reduction and immobilisation) or surgical (open reduction and internal fixation) approaches. Both of these modalities of treatment have advantages and disadvantages, as well as indications and contraindications...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Malnutrition has been found to have negative effects on the immune system and inflammatory responses, impairing the wound healing process. Free flap failure is a serious complication in patients undergoing microvascular reconstruction, as it increases patient morbidity, length of stay in the hospital, patient, and hospital costs, as well as causes the need for further surgical interventions1 . Malnutrition is estimated to be present in 35-50% of head and neck cancer patients with higher rates in those experiencing hypo-oropharyngeal disease...

Study Design: Technical note. Objective: The lower nasal architecture is dependent on caudal septal integrity. Deviations of the caudal septum can compromise nasal airflow. The presence of anterior nasal spine deviations contributes to septal and medial crural shifting with ipsilateral encroachment. It is essential to identify nasal spine deviation during surgery in order to reconstruct the septum in a midline position at its base. This allows an appropriate management plan that creates a better functional and aesthetically pleasing outcome...

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: The clinical decision to pursue harmonic scalpel (HS) method vs conventional hemostasis to treat head and neck cancers has been arguably predicated on the clinical outcomes observed. This study aims to evaluate the surgical outcomes of neck dissection between both techniques and perform an updated meta-analysis using the available literature. METHODS: We searched PubMed, Scopus, and Cochrane Library through 31st December 2021, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

STUDY DESIGN: Human bone marrow stem cells (hBMSCs) and human adipose-derived stem cells (hADSCs) have demonstrated the capability to regenerate bone once they have differentiated into osteoblasts. OBJECTIVE: This systematic review aimed to evaluate the in vitro osteogenic differentiation potential of these cells when seeded in a poly (lactic- co -glycolic) acid (PLGA) scaffold. METHODS: A literature search of 4 databases following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted in January 2021 for studies evaluating the osteogenic differentiation potential of hBMSCs and hADSCs seeded in a PLGA scaffold...

STUDY DESIGN: Cadaveric investigation. OBJECTIVE: Rigid internal fixation (RIF) using plates and screws is often not feasible in low and middle-income countries due to limited resources. Interosseous wiring to achieve semi-rigid fixation is often used, but lacks biomechanical force data. Herein we aim to quantitatively compare interosseous wiring to RIF. METHODS: Cadaveric mandibles were fractured at the parasymphysis and angle. Fixation was achieved using interosseous wiring in both single wire loop and figure-of-eight formations, as well as plate and screw fixation (n = 5 for each fixation type at each fracture site)...

The purpose of this study was to investigate the epidemiology, pattern of injury and management of facial dog bite injuries. Methods: The authors conducted a retrospective cohort study over a 5-year period of patients who sustained a facial dog bite injury. The study setting was an Oral and Maxillofacial Surgery Department at a level 1 trauma centre, servicing an estimated catchment population in excess of 950,000 people. Results: In total, 171 patients were managed in the designated period from January 2017 to January 2022...

Craniomaxillofacial trauma is primarily diagnosed and managed by oral and maxillofacial surgeons. Among the cases encountered, midface fractures involving orbital walls are highly prevalent. In these fractures, involvement of the orbital walls, particularly floor of the orbit, can lead to considerable aesthetic and functional limitations. From a maxillofacial perspective, indications for surgical repair of orbital floor encompass marked decrease in ocular motility, fracture affecting more than 50% of surface area, an increase in orbital volume exceeding 18% and enophthalmos greater than 2 mm...

OBJECTIVES: This retrospective cohort study aimed to analyze volumes of craniomaxillofacial bone and masticatory muscles of young adults with bilateral idiopathic condylar resorption. METHODS: This was a retrospective cohort study of 84 adults with bilateral idiopathic condylar resorption (BCR) and 48 adults with normal temporal-mandibular joint (TMJ) matched for age and sex (mean age, 23.2 ± 3.6 years). The volumes of craniomaxillofacial bone and masticatory muscles, as well as intercondylar angle were measured...

Sagliker syndrome (SS) is a rare complication in patients with chronic kidney disease (CKD) on prolonged dialysis due to uncontrolled secondary hyperparathyroidism (SHPT). SS manifests with a constellation of clinical manifestations, including short stature, craniomaxillofacial abnormalities, hearing loss, and neuropsychiatric disorders. This article reports a 33-year-old male patient with CKD who complained of progressive disfiguring facial changes, multiple recurrent fractures, and shortened height. The condition affects his quality of life...

OBJECTIVE: Three-dimensional (3D) modeling technology aids the reconstructive surgeon in designing and tailoring individualized implants for the reconstruction of complex craniofacial fractures. Three-dimensional modeling and printing have traditionally been outsourced to commercial vendors but can now be incorporated into both private and academic craniomaxillofacial practices. The goal of this report is to present a low-cost, standardized office-based workflow for restoring bony orbital volume in traumatic orbital fractures...

BACKGROUND: Implant surgery is a popular operation in craniomaxillofacial surgery, but the occurrence of peri-implantitis affects the success and survival rate of the implant. Research has found that Th-cell-related cytokines are associated with peri-implantitis. However, the distribution and proportions of Th-cell subsets in submandibular lymph nodes' immune environments during the progression of peri-implantitis remain unclear. METHODS: Forty-eight rats were randomly divided into 4 groups: the control group, the 1-week ligation peri-implantitis induction (Lig 1w) group, the Lig 2w group, and the Lig 4w group (n=12)...

BACKGROUND: Craniomaxillofacial tissue defects are clinical defects involving craniomaxillofacial and oral soft and hard tissues. They are characterized by defect-shaped irregularities, bacterial and inflammatory environments, and the need for functional recovery. Conventional clinical treatments are currently unable to achieve regeneration of high-quality oral craniomaxillofacial tissue. As a natural biomaterial, silk fibroin (SF) has been widely studied in biomedicine and has broad prospects for use in tissue regeneration...

Canine craniomaxillofacial osteosarcoma (OSA) is most commonly treated surgically; however, in cases where surgery is not feasible or non-invasive treatment is desired, stereotactic body radiation therapy (SBRT) may be elected for local tumour control. In this study, we evaluated 35 dogs treated with SBRT. Nine dogs (26%) had calvarial, seven (20%) had mandibular and 19 (54%) had maxillary OSA. Median time to first event (TFE) was 171 days, and overall median survival time (MST) was 232 days. Site-specific MSTs were 144 days for mandible, 236 days for calvarium and 232 days for maxilla (p = ...
