RESUMEN

BACKGROUND: This research aims to assess the demographic characteristics, prevalence, outcomes, and complications in chronic kidney disease (CKD) patients following mandible fractures in the United States using a nationally representative database. METHODS: We analyzed data from the National Inpatient Sample from 2010 to 2019 in the United States. Patients with mandible fractures were categorized into three groups based on the International Classification of Diseases, Ninth and Tenth Revisions (ICD-9-CM and ICD-10-CM): end-stage renal disease (ESRD), non-ESRD CKD, and healthy kidney function. Chi-squared tests and analysis of variance (ANOVA) were used to compare these groups. Additionally, multivariate regression analysis was performed to determine whether CKD is an independent risk factor for complications in patients with mandible fractures. RESULTS: A total of 38,481 patients in the United States were estimated to have experienced mandible fractures between 2010 and 2019. The incidence rate of non-ESRD CKD in patients with mandible fractures significantly increased over time, while the prevalence of ESRD remained stable during the ten-year period. Compared to the healthy kidney function group, patients with chronic kidney disease exhibited higher hospital costs, longer hospitalization durations, and higher in-hospital mortality rates. Additionally, they had greater odds ratios for most of the investigated complications. CONCLUSIONS: This study revealed a steady annual increase in the morbidity rate of non-ESRD CKD among patients with mandible fractures, while ESRD prevalence remained stable over ten years. We observed a close association between chronic kidney disease and the prognosis of patients with mandible fractures. Clinicians should prioritize preventive measures and appropriate management of mandibular fractures in patients with CKD.

RESUMEN

A fracture of the mandibular condyle is a common fracture of the mandible. After the diagnosis has been made, there are various treatment options: wait and see, conservative or surgical. Which of these treatment options is best depends on several different factors and is often the subject of debate. A common complication of a fracture of the mandibular condyle is malocclusion. Malocclusion can cause problems - even in the long term - for which the patient often requires secondary treatment.

RESUMEN

OBJECTIVES: Double puncture arthrocentesis (DPA) of the temporomandibular joint (TMD) is considered an effective preservative option for managing mandibular condylar head fractures. However, the procedure is commonly performed by a traditional "blind" method using anatomical characteristics. In the present study, an ultrasonography (US) device was applied for the treatment of a case with a fractured mandibular condyle. METHODS: A 79-year-old female was diagnosed right side condylar head fracture complaining pain of right TMD and reduced mouth opening range: inter-incisor distance of 20 mm. Since the fracture position was high and inoperable, the decision was made to perform DPA of the TMD. The US probe was positioned parallel and slightly oblique to the major axis of the mandibular ramus. Both the posterior and anterior insertions into the joint space were performed according to the axis mentioned above, which enabled the operator to visualize the entirety of the needle. RESULTS: The device offered safety and ensured accuracy by providing real-time visual aid to the surgeon. The procedure provided an early increase in the inter-incisor distance (31 mm) and pain relief. CONCLUSIONS: Hence, for the preservative treatment of mandibular condylar head fractures, based on the present study, we recommend US-guided arthrocentesis as a safe, feasible, and effective therapeutic option instead of the conventional "blind" method.

RESUMEN

BACKGROUND: The sagittal fracture of the mandibular condyle can be fixed with absorbable long screws. Absorbable long screws are generally inserted from the lateral crest of the condyle and are as close as possible to the medial pole of the condyle to obtain sufficient retention force. However, in clinical practice, patients with locally comminuted condylar fractures and partial defects in the lateral crest are often encountered. We validated the use of absorbable plates and long screws to fix mandibular condylar fractures with lateral crest defects, and postoperative follow-up showed good results. METHODS: The preoperative design indicated that if conventional long screws were used, more soft tissue need to be pulled downward to achieve the appropriate drilling angle. If an absorbable plate was used, the degree of downward pulling of soft tissue was smaller, which can better protect the parotid gland tissue and facial nerve. The surgery was performed according to the preoperative design, using an absorbable plate scheme. RESULTS AND DISCUSSION: Postoperative CT confirmed a stable anatomical reduction of condyle. Four-month follow-up showed that the patient's facial shape, occlusion, and mouth opening were all good. Follow-up CT showed good fracture healing. It is feasible to use absorbable plates and long absorbable screws to fix mandibular condylar sagittal fracture accompanied by lateral condylar crest defect.

RESUMEN

BACKGROUND: Mandibular angle fractures (MAF) have a recognized complexity of treatment and an increased risk of incurring complications. METHODS: This retrospective study included 45 consecutive patients who were diagnosed with an isolated MAF and no other facial fractures. The average age was 27.3 (SD = 7.7). RESULTS: A comparatively low rate of complications (11.1%) and a low rate of reoperation (1.8%) are reported, along with a significant role of smoking in complications (p = 0.022). A non-significant association was noted between complications, male gender and assault as an aetiological factor. CONCLUSIONS: Review of the data from this study confirms that complication rates for patients attending the National Maxillofacial Unit are similar to or better than that of international studies. An overview of the aetiology of fracture complications is included.

RESUMEN

AIM: This study evaluated records of patients with maxillofacial trauma due to interpersonal violence (IPV) being treated in the emergency room of a level I trauma center hospital in São Paulo, Brazil. MATERIAL AND METHODS: Data of patients with maxillofacial trauma due to IPV recorded between January 2019 and December 2019 were retrospectively examined. Personal data, days on which they experienced IPV, and the type of maxillofacial trauma sustained were extracted and statistically analyzed (p < .050). RESULTS: During the analysis, 1034 patients with maxillofacial trauma were identified; of these patients, 292 (28.2%) who experienced trauma due to IPV were included in this study. There was a mean age of 32.6 years and the most common type of trauma was soft tissue injuries (38.7%). Mandible and nose fractures were more prevalent in males and females, respectively. Our data, when compared with other studies on maxillofacial trauma due to IPV, showed a lower prevalence and male-to-female ratio, and a higher presence of dentoalveolar trauma. Additionally, our data when compared with studies on maxillofacial trauma due to other causes showed lower mean age and male-to-female ratios, and a higher occurrence of nose fractures differing from the predominance of mandibular fractures. CONCLUSION: Oral and maxillofacial surgeons must be able to suspect and identify cases due to IPV among their patients with trauma. With our results, although each case has its individuality, we can suggest that cases of maxillofacial trauma in young, female, and nasal fracture patients may be suspicious for IPV.

RESUMEN

AIM: To evaluate the benefits of a long-term prophylactic antibiotic regimen following treatment of fractured mandibles with open reduction and internal fixation. MATERIAL AND METHODS: A prospective, randomized controlled trial was undertaken at Wits Oral Health Centre. Patients with mandibular fractures who were managed with open reduction and internal fixation using miniplates were randomized into 2 groups. The control group, the perioperative antibiotic (POA) group, was composed of patients who received intravenous (IV) antibiotic cover intraoperatively and a further 3 IV doses 24 hours postoperatively. The study group, the extended postoperative antibiotic (EPOA), was composed of patients who received similar doses as the control group but with an additional 5 days of oral antibiotics upon discharge. The patients were then evaluated for evidence of infection 1, 4, and 6 weeks postoperatively. RESULTS: A total of 77 patients were included in the study, 41 in the POA and 36 in the EPOA groups. Fourteen patients had evidence of infection noted within the 6-week follow-up period (10 in the POA and 4 in the EPOA groups). Statistical analysis with the Pearson Chi-square and Student t test showed no statistically significant difference ( P =0.399) between POA and EPOA groups. There were no significant differences between the groups with respect to site and etiology of fracture, duration of operation, and presence of infection ( P >0.05) during the 6-week review period. CONCLUSIONS: The extended use of antibiotic prophylaxis when managing mandibular fractures with open reduction and internal fixation offers no additional benefit in reducing postoperative infections.

RESUMEN

Cervical necrotizing fasciitis (CNF) is a rare condition in the United States, with very few cases reported as a sequela of mandibular fracture. The authors describe the case of a 40-year-old man with poor oral health and no significant past medical history who developed CNF following delayed treatment of an open mandibular fracture, leading to life-threatening septic shock, thrombophlebitis of the internal jugular vein, and septic emboli to the lungs. Successful management of this patient was accomplished by serial surgical debridement, the administration of broad-spectrum antibiotics, and hemodynamic support. Eventual reconstruction was performed with external fixation of the mandible fracture and split-thickness skin grafting for the left neck and chest wound. The authors recommend early treatment of open mandibular fractures for immunocompromised patients or patients with poor oral hygiene to avoid the rare but potentially fatal complication of CNF and highlight external fixation as a useful technique in select cases of complex mandibular fractures.

RESUMEN

BACKGROUND: Mandible fracture management requires postoperative dietary modifications to promote healing. Over 20 million Americans live in food deserts, low-income neighborhoods over one mile from a grocery store. The relationship between food desert residence (FDR) and adherence to postoperative dietary instructions remains unexplored. PURPOSE: This study's purpose is to evaluate the relationships between FDR, known risk factors, dietary adherence, and complications among patients with isolated mandible fractures. STUDY DESIGN, SETTING, SAMPLE: This retrospective cohort study was conducted at a level 1 trauma center and analyzed patients with mandible fractures between January 2015 and December 2020. Inclusion criteria included operative treatment of adult patients for mandible fractures; pregnant, incarcerated, and patients with incomplete data were excluded. PREDICTOR VARIABLE: FDR was the predictor variable of interest. FDR (coded yes or no) was generated by converting patient addresses to census tract GeoIDs and comparing them to the US Department of Agriculture Food Access Research Atlas. MAIN OUTCOME VARIABLES: The study examined two outcome variables: dietary adherence and postoperative complications. Dietary adherence was coded as adherent or nonadherent, indicating documented compliance with postoperative dietary modifications. Postoperative complications were coded as present or absent, reflecting infection, hardware failure, and mandible malunion or nonunion. COVARIATES: The covariates analyzed included age, sex, ethnicity, mechanism of injury, medical and psychiatric comorbidities (including diagnoses such as diabetes, hypertension, and schizophrenia), and tobacco use. ANALYSES: Relative risks (RRs) and multivariate logistic regression models were generated for both outcome variables. Two-tailed P values < 0.05 were considered statistically significant. RESULTS: During the study period, 143 patients had complete data allowing for FDR and dietary adherence determination, 124 of whom (86.7%) had complication data recorded. Of the cohort, 51/143 (35.7%) resided within a food desert, 30/143 (21.0%) exhibited dietary nonadherence, and 46/124 (37.1%) experienced complications. FDR was not associated with increased risk of dietary nonadherence (RR 0.92, 95% confidence interval [CI] 0.52 to 1.61, P = .76) or complications (RR 1.19, 95% CI 0.75 to 1.89; P = .46). On multivariate regression, dietary nonadherence was associated with increased complications (odds ratio 2.85, 95% CI 1.01 to 8.09, P = .049). CONCLUSION AND RELEVANCE: There was no association between FDR and dietary nonadherence or complications in mandible fracture patients. However, dietary nonadherence was associated with complications, highlighting the need for further research and intervention.

RESUMEN

Mandibular fractures are the second most common maxillofacial fractures. The prevalent treatment for this kind of fractures is either a surgical procedure such as maxillomandibular fixation or open reduction and internal fixation or a combination of both. Sometimes the patients might develop locoregional postoperative complications. The most frequently reported complications are trigeminal V3 injury and surgical site infection. A 4-year retrospective study was performed at the Department of Oral and Maxillofacial Surgery, Policlinico Umberto I of Rome, Italy, and the postoperative complications after mandibular fracture surgical treatment were collected. The authors studied the characteristics of each complication and the correlation with the type of mandibular fracture and the surgical treatment chosen.

RESUMEN

Pycnodysostosis is an ultra-rare osteosclerotic skeletal disorder characterized by short stature, susceptibly to fractures, acroosteolysis of the distal phalanges, and craniofacial features (frontal bossing, prominent nose, obtuse mandibular angle, micrognathia). Dental abnormalities (delayed eruption of teeth, hypodontia, malocclusion, dental crowding, persistence of deciduous teeth, enamel hypoplasia, and increased caries) are also frequent; due to bone metabolism alteration, the patients have an increased risk for jaw osteomyelitis, especially after tooth extraction or mandible fracture. Other complications are obstructive sleep apnea, endocrine alterations and cytopenia. Pycnodysostosis is caused by biallelic loss of function variants in CTSK gene, coding the lysosomal protease cathepsin K. CTSK is involved in the degradation of bone matrix proteins, such as type I and type II collagen. In pycnodysostosis, this degradation is decreased, leading to increased bone density and bone fragility with pathological fractures and poor healing. We present a clinical report of a female adult patient with typical pycnodysostosis phenotype. At the age of 52 years, she had a pathological spontaneous fracture of the right mandible complicated by osteonecrosis, treated with load bearing osteosynthesis. The direct sequencing of CTSK gene revealed the presence of the pathogenic homozygous variant c.746T>A, (p.Ile249Asn), that confirmed the diagnosis of pycnodysostosis. We also review the literature case series published to date, that suggest to always consider the diagnosis of pycnodysostosis in case of osteosclerosis, even in the absence of brachydactyly or short stature. This report details the natural history of the disease in this patient, from childhood to adulthood, and highlights the importance of a quality of life assessment. In addition, we describe a case of mandibular osteonecrosis and spontaneous fracture in pycnodysostosis, drawing attention on the maxillofacial complications in these patients and on the importance of a personalized follow-up.

RESUMEN

OBJECTIVE: This study aims to determine the occurrence of complications before and after the treatment of facial fractures, as well as the impact of the factors on the treatment results and evaluation of their relationships. PATIENTS AND METHODS: This is a prospective case-control study comprising 90 patients aged between 18 and 65 with facial fractures. Depending on the treatment method, patients were divided into three groups: those treated surgically using a transcutaneous approach, those treated surgically using a transmucosal approach, and those treated conservatively (control group). Following complications before and after treatment were compared: malocclusions, paresthesias, facial asymmetry, diplopia, and limited mouth opening. The follow-up period after the treatment of choice was six months. RESULTS: There was a significant reduction in complications after treatment: malocclusion, paresthesia, facial asymmetry, and limited mouth opening. Regarding the transcutaneous approach, there is a substantial reduction in the number of complications after treatment, such as malocclusions (p=0.008), paresthesias (p=0.004), and facial asymmetries (p<0.001). Similar results were obtained for the transmucosal approach. Pain intensity positively correlated with preoperative complications: malocclusion, paresthesias, and facial asymmetry. The range of mouth opening had a negative interdependence with malocclusion before and after treatment with infection, fractura male sanata, malocclusion, paresthesias, postoperative level of mouth opening, and damage to the facial nerve. CONCLUSIONS: There is no difference in the reduction of preoperative and postoperative complications related to surgery when an incision is made through the skin or mucosa. Malocclusions, paresthesias, and facial asymmetry are reduced through surgical methods.

RESUMEN

Postoperative complications following mandibular fracture treatment vary from local wound infections to severe conditions including osteomyelitis and impaired fracture healing. Several risk factors have been associated with the development healing disorders, including fracture localisation, treatment modality and substance abuse. However, limited research on the sex-specific influence of these complications exists. A total of about 300,000 female and male patients with mandibular fractures were examined in two cohorts. After matching for confounders (age, nicotine and alcohol dependence, malnutrition, overweight, anaemia, diabetes, osteoporosis and vitamin D deficiency), two cohorts were compared with propensity-score-matched patients according to outcomes (osteomyelitis, pseudoarthrosis and disruption of the wound) within 1 year after fracture. There were significant differences between female and male patients regarding the occurrence of osteomyelitis (odds ratio [OR] [95% confidence interval]: 0.621 [0.563; 0.686]) and disruption of the wound (OR [95% confidence interval]: 0.703 [0.632; 0.782]). Surprisingly, matching for the expected confounders did not change the results substantially. Sex plays a dominant role in determining the risk stratification for postoperative osteomyelitis and disruption of the wound, after accounting for other potential confounding factors. Additional research is needed to understand the underlying mechanisms and to develop sex-specific strategies to prevent these complications.

RESUMEN

Due to the anatomical proximity between the skull and the face, maxillofacial trauma can often cause injuries to cranial structures. Among these complications are carotid-cavernous fistulas (CCF), which are rare in maxillofacial trauma, although their etiology is usually traumatic. They are described as an atypical communication between the internal carotid artery and the cavernous sinus, which can generate a sudden change in the direction and distribution of blood flow between the brain and orbit. This paper aims to report a case of craniomaxillofacial trauma in which the patient evolved with diplopia, palpebral ptosis, and ophthalmoplegia of the left eye, diagnosed as traumatic CCF. The oral and maxillofacial surgery and traumatology team of the University Hospital of Western Paraná was observed these symptoms for the first time during post-operative follow-up after one day of surgery to repair mandibular fractures of the patient in question. With the identifying the signs and symptoms, a neurosurgery was requested for assessment and management. After clinical evaluation and imaging tests, they diagnosed the condition as CCF 5 days after the mandibular fractures and the patient was referred for treatment. Surgery was performed, in the same day, to resolve the CCF with the endovascularly by embolization with micromoles. The CCF was resolved and the patient continued on outpatient follow-up, progressing without sequelae from the CCF or mandibular fractures.

RESUMEN

After a fracture of the condyle, the head of the condyle is often pulled inwards, which causes the fractured part to angulate medially. This change can cause a disbalance in the masticatory system. The disbalance could lead to contact stress differences within the temporomandibular joints (TMJs) which might induce remodelling within the TMJ to restore the balance. The contact stress in the fractured condyle during open and closing movements is expected to decrease, while the contact stress in the non-fractured condyle will increase. In a clinical situation this is hard to investigate. Therefore, a finite element model (FEM) was used. In the FEM a fractured right condyle with an angulation was induced, which was placed at different degrees, varying from 5° to 50° in steps of 5°. This study shows only minor differences in amount of contact stress between the fractured and the non-fractured condyle. The amount of contact stress in the condyles does not increase with a higher degree of angulation. However, with larger angulations, the contact stress within the fractured condyle is more centralized. Clinically, this more centralized area could be associated with complaints, such as pain. In conclusion, due to the more centralized contact stress in the fractured condyle, one would expect some minor remodelling on the fractured side with more angulation.

RESUMEN

BACKGROUND: Open reduction internal fixation (ORIF) of mandibular subcondylar fractures (MSF) involves several variables that could affect decision making. There is insufficient data regarding factors influencing the outcomes of MSF ORIF. PURPOSE: The purpose of this study was to investigate factors associated with quality of bony reduction of MSF and occlusion, after ORIF. STUDY DESIGN, SETTING, AND SAMPLE: We designed a retrospective cohort study of consecutively treated subjects for MSF ORIF, ages 18 to 64 years, by University of Illinois' Department of Oral and Maxillofacial Surgery, between January 1, 2013, and January 26, 2021. PREDICTOR VARIABLE: The primary predictor variable was the vertical level of MSF from the gonial angle. Secondary predictor variables included surgeon, fixation scheme (number and configuration of miniplate), surgical approach, time to surgery, mechanism of injury, vertical fragment overlap, overlying soft tissue thickness, presence of other mandibular fractures, and severity and direction of displacement. MAIN OUTCOME VARIABLES: The primary outcome variable was the mean radiographic reduction score (RRS), rated by 2 blinded observers on a 1 to 5 scale. The secondary outcome variable was presence of postoperative malocclusion as documented in the medical records. COVARIATES: Covariates were age and sex. ANALYSES: Descriptive statistics were computed. To investigate the influence of the predictor variables on reduction quality, multifactorial analysis of variance with post hoc Tukey test was performed. For malocclusion, χ2 test was performed. The level of significance was set at P < .05. RESULTS: Thirty-eight MSF in 37 subjects were included. Mean age was 32.7 years (range 18 to 64), and 83.8% were male. Mean RRS was 4.38 (standard deviation 0.77). Fixation scheme was the only variable that showed significant impact on RRS: single-straight miniplate had lower scores than double-straight (-1.50, P = .011), rhomboid (-1.29, P = .036), and ladder miniplates (-1.38, P = .048). There was 1 incidence of malocclusion (2.7%) which resolved without intervention. CONCLUSIONS AND RELEVANCE: Favorable reduction (anatomic reduction to mild discrepancies) can be achieved without malocclusion using double-straight, or rhomboid-shaped or ladder-shaped miniplates, without influences from patient or injury-related factors. In contrast, single-straight miniplate fixation resulted in moderate discrepancies in reduction, although it did not lead to malocclusion.

RESUMEN

Mandible fracture management has evolved dramatically. Therefore, the variety of surgical complications associated with mandibular fractures, and their incidences, have continued to change as well. This article aims to assess the most common and most concerning complications that can occur secondary to management of mandibular fractures by examining categories of complication types.

RESUMEN

Falls are a leading cause of injuries to the temporomandibular joint (TMJ) in the paediatric age group. In low- and middle-income nations, after injury to a child's chin, a careful clinical examination of the mandible and TMJ is sometimes omitted. Paediatric mandibular condylar fractures tend to shatter the relatively narrow condylar head, leading to ankylosis to the skull base, which leads to debilitating progressive deformity.1 Early surgical release is then the sole modality of treatment and needs to be followed up by several weeks of active mouth-opening exercises to prevent re-ankylosis, which are crucial in the immediate post-operative period. Unfortunately, as patient cooperation is low owing to uncomfortable jaw mobilization, we fabricated a simple acrylic appliance which is easy to use.

RESUMEN

BACKGROUND: Fractures of the atrophic mandible have been historically treated in various ways, from intermaxillary fixation to internal fixation, some cases require bone grafts. Besides, the Luhr classification serves as a guide to select the type of treatment. OBJECTIVE: To show the treatment of fractures in atrophic mandible with plates and screws, and the potential indications of bone graft in this type of fractures. METHOD: We presented a serie of 17 patients with atrophic mandible treated with plates and screws, some of them no blocked system and other with locked screws. For patients in luhr classes II and III cancellous bone grafts were used, looking for best osteogenic response, harvesting for the proximal third of the tibia. RESULTS: Postoperative progress was generally uneventful. Oral intake with purees was resumed 24 hours after surgery, as well as ambulation. Fracture healing at 6 months was seen in 17 patients. One patient died before the 6-month time point as the result of a stroke. Delayed union was diagnosed 3 months after surgery in another patient, who refused secondary treatment. CONCLUSIONS: Treatment of fractures in atrophic mandibles with plates and screws is a reliable procedure. Luhr classification provide useful guidance regarding the use of bone grafts for best osteogenic response in the fracture. This treatment allows a quick restart of the feeding by mouth and movilization of the patients.


ANTECEDENTES: Las fracturas en mandíbula atrófica han sido tratadas desde con fijación intermaxilar hasta con osteosíntesis. Pueden requerir injertos óseos. La clasificación de Luhr es una guía para orientar el tratamiento. OBJETIVO: Mostrar el tratamiento de fracturas en mandíbula atrófica con placas y tornillos y las posibles indicaciones de uso de injerto óseo en este tipo de fracturas. MÉTODO: Se presenta una serie de 17 pacientes con mandíbula atrófica fracturada tratada con placas y tornillos, algunas con sistemas no bloqueados y otros bloqueados. En las de clase II and III se aplicó injerto óseo esponjoso para mejorar la capacidad osteogénica. El injerto se tomó del tercio proximal de la tibia, previa evaluación radiológica. RESULTADOS: La evolución en general fue satisfactoria. Se inició la vía oral con papillas y los pacientes deambularon a las 24 h de posoperatorio. Se observó consolidación en 17 pacientes. Hubo una defunción por enfermedad vascular cerebral antes de 6 meses. Una paciente tuvo retardo de consolidación diagnosticado al tercer mes, pero no aceptó tratamiento secundario. CONCLUSIONES: El tratamiento de las fracturas mandibulares atróficas con placa y tornillos bajo concepto de carga absorbida es un procedimiento confiable. La clasificación de Luhr es útil para orientar la utilización de injerto óseo, buscando mejorar la capacidad osteogénica en la fractura. Este tratamiento permite un pronto reinicio de la vía oral, así como la movilización de los pacientes.

RESUMEN

The analysis of 387 cases of mandibular fractures complicated by posttraumatic infections is presented. These infections were quite diverse - from local suppuration of soft tissues surrounding the fracture to widespread processes affecting fatty tissue planes, including the anterior and posterior mediastinum. Infectious complications determine the injury outcome in each case - recovery, disability, or death. Two clinical observations with lethal outcomes are described.
