Diagnosis and management of Ludwig's angina: An evidence-based review.

BACKGROUND: Ludwig's angina is a potentially deadly condition that must not be missed in the emergency department (ED). OBJECTIVE: The purpose of this narrative review article is to provide a summary of the epidemiology, pathophysiology, diagnosis, and management of Ludwig's angina with a focus on emergency clinicians. DISCUSSION: Ludwig's angina is a rapidly spreading infection that involves the floor of the mouth. It occurs more commonly in those with poor dentition or immunosuppression. Patients may have a woody or indurated floor of the mouth with submandibular swelling. Trismus is a late finding. Computed tomography of the neck soft tissue with contrast is preferred if the patient is able to safely leave the ED and can tolerate lying supine. Point-of-care ultrasound can be a useful adjunct, particularly in those who cannot tolerate lying supine. Due to the threat of rapid airway compromise, emergent consultation to anesthesia and otolaryngology, if available, may be helpful if a definitive airway is required. The first line approach for airway intervention in the ED is flexible intubating endoscopy with preparation for a surgical airway. Broad spectrum antibiotics and surgical source control are keys in treating the infection. These patients should then be admitted to the intensive care unit for close airway observation. CONCLUSION: Ludwig's angina is a life-threatening condition that all emergency clinicians need to consider. It is important for clinicians to be aware of the current evidence regarding the diagnosis, management, and disposition of these patients.

Ludwig's angina: a multidisciplinary concern.

Although relatively uncommon, Ludwig's angina is a potentially life-threatening infection of the floor of the mouth and neck. There is a danger of airway obstruction by swelling in the area and displacement of the tongue, and patients are at risk of deterioration. There are many factors thought to place patients at an increased risk of developing the condition. These include recent dental treatment, dental caries or generally poor dentition, chronic disease such as diabetes, alcoholism and malnutrition, and patients with compromised immune systems (eg AIDS, organ transplantation). This article examines the aetiology of Ludwig's angina and considers the presentation, diagnosis and treatment of a patient who presented to an out-of-hours streaming area of a local emergency department, with an emphasis on the importance of a multidisciplinary approach. It also considers the need for ongoing education and awareness of health professionals to ensure the successful diagnosis, management and treatment of this condition, particularly in the context of patients with poor access to dental care presenting first to the emergency department.

ENT indications for Hyperbaric Oxygen Therapy.

ENT indications for Hyperbaric Oxygen Therapy. Hyperbaric Oxygen (HBO) therapy is a treatment where patients breathe 100% oxygen while exposed to high environmental pressure in a hyperbaric chamber. This hyperoxygenation has several beneficial effects as an adjunctive treatment in a number of ENT-related conditions and diseases. These can be summarized as anti-ischaemic effects (delivery of oxygen to otherwise ischaemic tissues, reduction of ischaemia-reperfusion damage), anti-infectious effects (bacteriostasis, improved leucocyte phagocytosis bactericidal activity and optimization of antibiotic therapy) and wound-healing effects (stimulation of granulation tissue formation and stabilization). Since HBO therapy has a clear physiologic rationale, a demonstrated effect (although difficult to "prove" with placebo controlled randomized trials) in certain indications and certain side-effects, it is proposed that it should be considered an integral part of the (combined surgical and pharmacological) treatment of patients, and not simply as a supplementation of oxygen. Furthermore, the importance of a well-trained medical and technical staff to ensure proper selection and the correct follow-up of patients should not be underestimated.

Ludwig's Angina.

Ludwig's angina is a severe diffuse cellulitis that presents an acute onset and spreads rapidly and bilaterally. It can affect the submandibular, sublingual or submental spaces resulting in a state of emergency. Early diagnosis and urgent management could be a life-saving procedure. We report a case of wide spread sialadenitis infection extending to the neck with trismus and elevation of the floor of the mouth that caused an obstruction of the airway and resulted in an inspiratory dyspnea and a stridor. The patient was directed to maintain the airway by elective tracheostomy. An appropriate use of parenteral antibiotics, airway protection techniques, and potential surgical drainage of the infection remain the standard protocol of treatment in advanced cases of Ludwig's angina. The aim of this case report is to emphasize on the importance of early diagnosis and appropriate management of Ludwig's angina.

Facial Swelling After Dental Work Done: A Case of Ludwig's Angina.

Ludwig's angina is a fast-spreading cellulitis located on the floor of the oropharynx and neck (Tami, Othman, Sudhakar, & McKinnon, 2020). Patients may present with a wide range of symptoms depending on the severity of the condition (Reynolds & Chow, 2007). Emergency nurse practitioners need to promptly identify, diagnose, and treat patients with this problem, with close attention to the patient's airway. A compromised airway is the leading cause of mortality from this condition (McDonnough et al., 2019). The diagnosis is generally made with a comprehensive history and physical examination, laboratory values, and imaging studies such as computer tomography (Bridwell, Gottlieb, Koyfman, & Long, 2021). Management includes admission to the hospital, broad-spectrum antibiotics, and specialist surgical consultation (Bridwell et al., 2021).

Ludwig's Angina: Higher Incidence and Worse Outcomes Associated With the Onset of the Coronavirus Disease 2019 Pandemic.

Background: Ludwig's angina (LA) is a diffuse cellulitis of the submandibular space and adjacent tissues. During the coronavirus disease 2019 (COVID-19) pandemic, odontogenic treatments were often delayed because of the implementation of safety measures to avoid the spread of the virus. We hypothesized that delayed odontogenic treatments associated with the onset of the COVID-19 pandemic would be associated with an increase in the incidence of LA and worse outcomes related to these infections. Patients and Methods: Patients from June 2018 to June 2022 with computed tomography images suggestive of LA and confirmed by ear, nose, throat (ENT) consult were included. We abstracted demographics, outcomes, clinical management, and microbiology. Patients were stratified into pre-COVID and COVID-onset. Our primary outcome, incidence of LA, was defined as: (new LA cases) ÷ (ED evaluations of oral or dental infections × 1.5 years). Results: In the pre-COVID group, we identified 32 of 1,301 patients with LA for an incidence of 0.02 per year. The COVID-onset group consisted of 41 of 641 patients, with an incidence of 0.04 per year. In the COVID-onset group, progression to necrotizing fasciitis was more likely (0% vs. 15%; p < 0.024), and they returned to the operating room for repeated debridement (3% vs. 22%; p < 0.020). Likewise, hospital length of stay, intensive care unit (ICU) length of stay, and ventilator days were higher (4.3 ± 3.5 vs. 9.5 ± 11.3; 1.1 ± 1.2 vs. 9.5 ± 7.1; 0.3 ± 1 vs. 3.6 ± 7.1; p < 0.001). Conclusions: Although the prognosis for dental infections diagnosed early is generally favorable, we observed a notable increase in the incidence of LA after the onset of the COVID-19 pandemic. Moreover, complications stemming from these infections became more severe in the COVID-onset era. Specifically, the likelihood of necrotizing fasciitis showed a substantial increase, accompanied by an increased risk of respiratory failure and mediastinitis.

Spread of odontogenic infections in Port Harcourt, Nigeria.

PURPOSE: Odontogenic infections constitute a substantial portion of diseases encountered by oral and maxillofacial surgeons. Infections start from dental tissues and sometimes rapidly spread to contiguous spaces. The consequence is a fulminant disease with significant morbidity and mortality. The study was aimed at studying the pattern of spread, approach to management, and outcome of these infections at a Nigerian teaching hospital. PATIENTS AND METHODS: A retrospective study of all patients with orofacial infections who presented to our center over an 18-month period was carried out. The medical records were reviewed to retrieve the following: age, gender, source of infection, anatomic fascial spaces involved, associated medical conditions, various treatment modalities, types of antibiotics administered, causative micro-organisms, length of stay in the hospital, and any complications encountered. Infections were classified into 2 categories: those that are confined to the dentoalveolar tissues belong to category I, and those that have spread into the local/regional soft tissue spaces and beyond belong to category II. RESULTS: Odontogenic infections constituted 11.3% of the total oral and maxillofacial surgery cases. A total of 261 patients were treated for odontogenic infections. There were 146 female patients (59.8%) and 98 male patients (40.2%) in the first category, whereas the second category comprised 10 male patients (58.8%) and 7 female patients (41.2%). The fascial spaces involved, in descending order, were submasseteric in 10 (22.7%), submandibular in 9 (20.5%), and sublingual in 6 (13.6%). The causative micro-organisms commonly found were Klebsiella and Streptococcus spp. Incision and drainage were performed in the 17 cases with spreading infection. Amoxicillin, amoxicillin/clavulanate, and metronidazole were the most routinely administered antibiotics. CONCLUSIONS: Our experience shows that delay in presentation, self-medication, aging, male gender, and unusual causative agents are some of the factors associated with spread. Therefore efforts must be made to further improve public dental awareness.

Ludwig's angina as an extremely unusual complication for direct microlaryngoscopy.

BACKGROUND: An extremely rare case that to our knowledge has not been reported before is described, in which a patient had a Ludwig's angina as a complication of direct microlaryngoscopy. METHODS: We report a Ludwig's angina after a direct microlaryngoscopy for a Reinke's edema, due to erosion on the internal face of the mandible produced by compression of the laryngoscope. RESULTS: The patient underwent placement of 2 drainages, intraoral and cervical, and several incisions on the floor of the mouth, with intravenous corticosteroids and antibiotics and with resolution of the illness without performing tracheostomy. CONCLUSIONS: Ludwig's angina is an extremely rare complication of microlaryngoscopy, but it is potentially life-threatening. Early diagnosis and treatment resulted in survival of the patient without complications.

Management of pediatric head and neck infections in the emergency department.

Head and neck infections can spread to nearby structures, compromising the airway and progressing to life-threatening events. Pediatric head and neck infections can be difficult to recognize; emergency clinicians must know the signs and symptoms of head and neck infections for early diagnosis and urgent management in order to prevent complications and decrease hospitalization rates. This issue reviews presenting signs and symptoms of pediatric head and neck infections, discusses when diagnostic studies are indicated, and offers evidence-based recommendations for management. Conditions reviewed include mastoiditis, sinusitis, Ludwig angina, peritonsillar abscess, retropharyngeal abscess, Lemierre syndrome, and acute suppurative thyroiditis.

Severe soft tissue infections of the head and neck: a primer for critical care physicians.

Patients with severe infections of the potential spaces of the head and neck are commonly managed in the ICU. These infections may present with devastating complications such as airway obstruction, jugular septic thrombophlebitis, lung abscess, upper airway abscess rupture with asphyxiation, mediastinitis, pericarditis, and septic shock. A thorough understanding of the anatomy and microbiology of these infections is essential for proper management of these patients. Retropharyngeal, danger, prevertebral, lateral pharyngeal, and submandibular space infections and their site-specific clinical manifestations, complications, and therapeutic interventions are discussed.

Ludwig's angina in a 76-year-old man.

This case is of a 76-year-old man who presented to the emergency department with a 24-h history of a progressive tense, tender midline neck swelling. A computed tomography scan revealed Ludwig's angina and the patient went on to develop respiratory compromise and was admitted to the intensive care unit. The patient's clinical course later became complicated by abscess formation requiring drainage under general anaesthetic. He was eventually discharged home some 9 days after his initial presentation. The emergency medicine management issues surrounding Ludwig's angina are discussed briefly. This case highlights the dynamic airway changes seen in this uncommon condition. Whereas Ludwig's angina has previously been associated in the emergency medicine literature with a younger age group and in patients with a history of dental infection or treatment, this case highlights the fact that it may occur despite these two common associations.

Successful conservative management of Ludwig's angina in advanced pregnancy.

A 20 year-old female in her 32nd week of gestation presented to the Emergency Department with dysphonia and dysphagia associated to a recent recurrence of a periapical abscess. Her oral examination showed trismus, elevated tongue and neck swelling. A clinical diagnosis of Ludwig's angina was reached, and empirical antibiotic coverage was started. The decompression and drainage placement was performed successfully under local anesthesia without airway compromise. At the moment, no clear guidelines exist for the acute treatment of Ludwig's angina. Establishment of a secure airway has long been considered the gold standard, yet new literature suggests a more conservative management. Ascertaining an early diagnosis at the Emergency Department, and involvement of Anesthesia, Obstetrics, and, Ear, Nose and Throat specialist services is vital for materno-fetal wellbeing. Careful evaluation of the airway status in addition to prompt antimicrobial therapy with surgical decompression may represent a plausible alternative in pregnant patients.

Infections of the Neck.

Infection of the neck is a relatively common emergency department complaint. If not diagnosed and managed promptly, it may quickly progress to a life-threatening infection. These infections can result in true airway emergencies that may require fiberoptic or surgical airways. This article covers common, as well as rare but emergent, presentations and uses an evidence-based approach to discuss diagnostic and treatment modalities.

Ludwig Angina after First Aid Treatment: Possible Etiologies and Prevention-Case Report.

Ludwig angina is a life-threatening type of soft tissue cellulitis involving 3 compartments on the floor of the mouth including the submental, sublingual, and submandibular spaces bilaterally. Prevention, early recognition, and treatment of Ludwig angina are critical because this is a clinical diagnosis with unpredictable progression. This article describes a rare case of Ludwig angina that evolved from an odontogenic infection and the specific microbiology and clinical course and discusses possible etiologies and prevention.

A case of Ludwig angina: a case report and review of the literature.

Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature.

Unusual outcome of Ludwig's angina.

This is a report of 2 cases of Ludwig's angina. An Indonesian young female patient developed severe stridor after oral examination. Then she underwent tracheostomy and developed post decannulation dyspnea due to huge surgical emphysema. The second case regards an Indian young male who developed disseminated intravascular coagulation and died from hemorrhage. The objectives of our cases presentation are to avoid mouth examination of Ludwig's angina if we are not ready for performing tracheotomy and to be aware of the possible development of disseminated intravascular coagulation and post decannulation emphysema.

An upper airway obstruction emergency: Ludwig angina.

Ludwig angina remains a potentially lethal disease, rapidly spreading bilateral cellulitis of the submental, sublingual, and submandibular spaces, which bears the threat for rapid airway obstruction. Since the introduction of antibiotics in 1940s, the mortality was reduced significantly. This resulted in the rare occurrence of the disease, leaving many physicians with limited experience of Ludwig angina. Although the occurrence of Ludwig angina in adults is rare, its presence in the pediatric edentulous population is even more uncommon. Because the unfamiliarity with this disease is now increasing, unnecessary delaying diagnosis or inadequate management may occur and may result in serious complications. This presentation will consist of a historical review, discussion of pathophysiology, followed by clinical presentation, etiology, bacteriology, and management. With early diagnosis, airway observation and management, aggressive intravenous antibiotic therapy, and judicious surgical intervention, the disease should resolve without complications. In addition, the source of infection should be determined and eliminated if possible. A thoughtful, individualized management strategy seems to be the most reasonable approach to the disease.
