The first report of submandibular lymph node infection with Flavobacterium ceti in a horse and its complete genome sequence.

This is the first report describing the isolation and genome sequence of Flavobacterium ceti (F. ceti IJFC025) from a draining submandibular lymph node abscess in a 6-year-old mixed-breed mare in Korea. Since F. ceti is not a usual infectious pathogen that causes equine health problems, this study presents the complete genome sequence of F. ceti isolated from a submandibular lymph node abscess sample in Jeju, South Korea, in 2022. The entire genome sequence of F. ceti IJFC025 consisted of a 3,144,426-bp chromosome with 35.6% G+C content. Gene prediction revealed that this strain possesses 2909 coding sequences (CDSs), 74 tRNAs, and five rRNAs. Average nucleotide identity analysis of the whole-genome sequence revealed 98.6%-98.8% nucleotide identity between F. ceti IJFC025 and F. ceti CECT7184, which was previously isolated from beaked whales. PathogenFinder revealed four different virulence genes in the genome that could potentially cause infections in horses. F. ceti CECT7184 contained genes encoding propionyl-CoA carboxylase, 3-oxoacid CoA-transferase A subunit, and the translation initiation factor IF-1, whereas F. ceti IJFC025 does not. Instead, F. ceti IJFC025 harbors genes encoding deoxyhypusine synthase, whereas F. ceti CECT7184 does not. Antimicrobial susceptibility tests revealed that F. ceti IJFC025 is a multidrug-resistant strain that is resistant to gentamicin, ceftazidime, nalidixic acid, ciprofloxacin, and colistin. However, no resistance genes were detected in the whole-genome sequence. Because of the similarity of the clinical signs with those of strangles, this pathogen needs to be included in the differential diagnosis of submandibular lymphadenopathy in horses.

Severe Deep Fascial Spaces Infections with Pregnancy: A Retrospective Study.

Background: Odontogenic infections are common and self-limiting in most cases, but, they can lead to severe consequences and considerable morbidity and can even be fetal in spite of modern medical therapy. Patients and Methods: Retrospective study included data of pregnant patients with deep fascial space infections, done in Oral & Maxillofacial Surgery Department, Faculty of Dentistry. Alexandria University, and Oral & Maxillofacial Surgery Department, King Fahd Specialist Hospital, Burayda, Qassim, Saudi Arabia, from June2017 to Dec2022. Data were analyzed to study incidence, etiology, pattern, treatment modalities, outcomes, complications, and effects on pregnancy. Results: Thirty-eight pregnant patients, with a mean age of 30.8 ± 6.21 years, were included. The mean age of pregnancy was 24.5 ± 4.3 weeks. Diabetes mellitus was identified in seven cases (18.42%) and combined with hypertension in one case (2.63%) and with valvular heart disease in another one. The commonest affected single space was the submandibular space that occurred in six cases (15.8%). Canine space was the second single commonly involved one which occurred in five patients (13.2%). Complications occurred in 11 patients. Unesthetic scar occurred in three patients (7.9%). Trismus was observed in two patients (5.3%). Recurrent abscess was found in one case. Complications affecting the developing fetus and considered the most serious occurred in four patients: two cases of preterm labor and two cases of abortion. Conclusion: These infections may lead to serious outcomes and may have irreversible effects on the pregnancy and the developing fetus. Urgent intervention with multidisciplinary team to provide adequate care.

A Rare Case of Sinonasal Large Cell Neuroendocrine Carcinoma with Lymph Node Metastasis

Abstract Introduction/Objective Sinonasal carcinomas comprise less than 1% of cancers, and the most common types are squamous cell carcinoma at 51.6% and adenocarcinoma at 12.6%. There are only limited published reports of sinonasal large-cell neuroendocrine carcinoma (LCNEC). This entity has distinguishing immunohistochemical and histomorphologic features; it stains positively for neuroendocrine markers (i.e., synaptophysin and CD56) and histologically has abundant amphophilic cytoplasm with prominent nucleoli. Methods/Case Report We present a 60-year-old female patient who was evaluated for a submandibular neck lump. Computed tomography identified a 3.2 x 1.8 x 1.6 cm enhancing lesion with central necrosis in the right submandibular space, representing either an enlarged necrotic right submandibular lymph node or a neoplasm arising from the right submandibular gland. The pathology of the lymph node biopsy was consistent with metastatic high- grade neuroendocrine carcinoma. The neoplastic cells stained positively for INSM1, CK8/18, CK AE1/3 (subset), TTF- 1, and Ki-67 (50%). Dotatate positron emission tomography showed evidence of focal activity in the right anterior nasal cavity supporting evidence with primary nasal cavity origin. Nasal endoscopy was performed, visualizing an area of necrotic friable tissue. Pathology confirmed the presence of large cell neuroendocrine carcinoma in the right nasal biopsies with metastatic LCNEC in right neck levels 1, 2A, 2B, 3, and 4. The malignant cells on hematoxylin and eosin stain had similar morphology to those in the initial lymph node biopsy, supporting a diagnosis of LCNEC. Results (if a Case Study enter NA) NA Conclusion Sinonasal large-cell neuroendocrine carcinomas are extremely rare. Upon literature search, there have been fewer than ten case reports published of this entity. Furthermore, large-cell neuroendocrine carcinoma behaves aggressively, and diagnosing this entity could result in earlier intervention and better patient outcomes. Highlighting the possibility of this diagnosis could broaden differentials in neoplasms that arise from the nose.

Management of excessive submandibular abscess and anesthesia in epidermolysis bullosa

Management of excessive submandibular abscess and anesthesia in epidermolysis bullosa

Acute upper airway obstruction caused by mouth floor cellulitis in a patient of advanced age: a case report and literature review.

Mouth floor cellulitis is a type of diffuse cellulitis involving the submandibular, submental, and sublingual spaces. This condition may cause asphyxia due to elevation and posterior deviation of the tissues of the floor of the mouth. The severity of submandibular gland infection often escalates in the presence of underlying comorbidities. Advanced age, hyperglycemia, and an immunocompromised status often lead to the rapid development of infection, resulting in complications such as acute upper airway obstruction. These complications increase treatment difficulty and the risk of mortality. We herein report a case involving an older adult with diabetes who developed mouth floor cellulitis secondary to a submandibular gland infection. Despite the severity of the submandibular gland infection, a timely, effective, and multidisciplinary approach improved the patient's prognosis.

Extensive deep neck infection associated with acupuncture

Deep neck infections are rare but potentially lethal conditions that require prompt identification and management. They can occur in the peritonsillar, submandibular, parapharyngeal and retropharyngeal spaces. The most affected areas tend to differ by age, with tonsillitis being more common in children and odontogenic in older adults. Predisposing factors to infection can also influence location. Early treatment is paramount as airway compromise, septic shock and extension to adjacent structures can lead to morbidity and mortality. Here we report a case of extensive deep neck infection in an elderly diabetic patient with multiple abscesses involving the paraspinal space and extending anteriorly close to the carotid sheet, yet without airway compromise or hemodynamic instability. After further questioning, the likely mode of infection was identified as acupuncture in the affected region. We present a review of the presentations, differential diagnoses, treatments, and clinical course of adults with deep neck infections to highlight the importance of expeditious diagnosis and treatment.

Epidemiology and Management Paradigm of Head and Neck Infections, Including COVID-19 Pandemic Period: A 10-Year Retrospective Study in a Maxillofacial Center of Cluj-Napoca.

Background. The management of odontogenic infections varies across the globe. To shed light on the subject, this study delves into the practices of the Oral and Maxillofacial Department at Cluj-Napoca County Hospital. Material and Methods. This comprehensive retrospective analysis of 10 years of clinical experience covered a range of factors, including demographics, clinical and investigations factors, medical and surgical treatment approaches, and follow-up. Additionally, the study examined the change in trends over the course of the COVID-19 pandemic. Results. While head and neck infection occurrence had a decreasing trend before the COVID-19 pandemic, during the pandemic era the number of patients almost doubled. The infections were prevalent in the submandibular space, teeth being the prevalent cause. Young adults are prone to suffer from odontogenic infections. High levels of C reactive protein, ASA II-IV risk, and hepatic dysfunction indicated a longer time of hospitalization. The majority of antibiograms were negative, and the positive ones indicated Streptococcus and Staphylococcus species as prevalent pathogens. Extra- or intraoral surgical drainage and wide-spectrum antibiotics proved to be the workhorse for odontogenic infections. Conclusion. This study advances our understanding of oral and maxillofacial surgery and offers actionable strategies for improving patient outcomes in similar healthcare institutions worldwide.

Management of Severe Odontogenic Infection: Case Report

Introduction: Submandibular abscess caused by odontogenic infection is a frequent case, but in some cases it can be deadly because it spreads and blocks the respiratory tract. The purpose of this study is to described a case of fatal submandibular abscess with early management effective. Case report: A 46 years old male patient with complaints of left submandibular, submental, left buccal and left temporal swelling. History of systemic disease was denied. Patients complain of tightness and changes in voice. Therapeutic intervention consists of Covid- 19 screening, complete blood lab, abscess decompression under local anesthesia, left submandibular and submental through and through drainage incisions, drainage incisions in the buccal area as well as multiple tooth extractions and penrose drain applications both extra oral and intra oral carried out in general narcotics, and swab culture sensitivity and antibacterial resistance tests were carried out. The antibiotics given were ceftriaxone and metronidazole. The patient was followed up and showed good general condition and decreased swelling. Conclusion: Odontogenic infections that spread and block the respiratory tract can be deadly. The abscess can expand even more quickly during preparation for surgery. Decompression of an abscess can be an effective treatment so that the abscess does not spread further and can reduce the risks of the operation being carried out. The management carried out must be complete and comprehensive, in this case a drainage incision and extraction of the focal infection are carried out. Initially, broad spectrum antibiotics can be given, but if the results of the antibacterial resistance test are obtained, it is very important to give more specific antibiotics. Submandibular abscess with poor prognostic consequences obstructed respiratory tract must be treated immediately and closely monitored. Keywords: Abscess, Odontogenic infection, Decompression

Anatomy, Diagnosis, and Clinical Management of Deep Neck Space Infections

Any surgeon providing care to patients with congenital, oncologic, infectious, or traumatic processes impacting the head and neck should have an intimate knowledge of the local anatomy. The complex fascial system in this region results in a series of loosely and tightly bound spaces that can both harbor and/or facilitate the rapid spread of infections through these fascial planes and potential spaces. Deep neck space infections may occur spontaneously from cutaneous, lymphatic, odontogenic, otologic, salivary gland, sinus, and hematogenous sources or develop as the result of surgical/iatrogenic manipulation. These infections are typically polymicrobial, involving a mixture of Gram-positive cocci, Gram-negative rods, and beta-lactam-resistant anaerobes commonly found in the oropharyngeal flora. Other populations, such as immunocompromised or hospitalized patients, are particularly vulnerable to infection by certain opportunistic and antibiotic-resistant pathogens. Understanding the deep neck anatomy is crucial for predicting the spread of infection and guiding treatment strategies. The superficial and deep cervical fascial planes form a series of compartments and spaces including the retropharyngeal, danger, prevertebral, carotid, parapharyngeal, submandibular, sublingual, parotid, masticator, temporal, and infrahyoid spaces. Despite their rarity in the post-antibiotic era, deep neck space infections pose a significant threat as they progress rapidly and can quickly lead to life-threatening complications. Delayed clinical presentation is common due to the compartmentalization by fascial planes, therefore early recognition requires a high index of suspicion, thorough clinical examination, and diagnostic imaging studies, typically contrast-enhanced computed tomography (CECT). Treatment requires a multidisciplinary approach, including advanced airway management, administration of empirical broad-spectrum antibiotics, and surgical drainage when indicated. This review provides a comprehensive overview of deep neck space anatomy and its defining fascial planes, as well as discussions on epidemiology, specific microbiology, clinical presentation, diagnosis, antibiotic selection, and surgical treatment options.

Management of Unilateral Buccal Necrotizing Fasciitis Superimposed with Submandibular Abscess At Colli Dextra in a Type 2 Diabetes Mellitus patient : A Case Report

Background: Necrotizing fasciitis (NF) is a relatively rare infectious disease of soft tissues that is characterized by necrosis of subcutaneous tissue and fascia and can even extend to involve the skin and muscles, with the main spread through odontogenic infections. One of the main comorbidities of necrotizing fasciitis is diabetes mellitus. Proper case management is needed because NF can result in severe morbidity and mortality if not treated at an early stage. Study Objective: This case report aims to report the management of patients with buccal necrotizing fasciitis complicated by submandibular abscesses with comorbid type 2 diabetes mellitus. Case Presentation: A 60-year-old woman came to RSHS complaining of swelling on her right cheek 20 days before hospital admission, which further extended to the jaw and neck area. Swelling on the patient's face did not improve after antibiotic treatment, and continued to enlarge to a size of 10x8x7 cm and 8x6x5 cm. The patient has a history of type 2 diabetes mellitus and controlled hypertension. The patient is diagnosed as necrotizing fasciitis and submandibular abscess. Patients are given antibiotic treatment and performed pus-tapping, necrotomy debridement, and tooth extraction. Conclusion : Necrotizing fasciitis involving the facial (especially buccal) area is rare, with the main cause being odontogenic, peritonsillar, or sinugenic. The main management includes debridement, reconstructive measures, and administration of antibiotics. Extensive tissue involvement, and poly-comorbid conditions can worsen the prognosis of necrotizing fasciitis. Keywords : Abscess, Buccal, Colli dextra, Necrotizing fasciitis, Submandibular

The Effect of the COVID-19 Pandemic on Odontogenic Cervicofacial Infections in a Single Center in Greece.

Odontogenic cervicofacial infections are still an ongoing problem, requiring immediate hospital admittance and management. The aim of this studyis to reflect the number of patients with cervicofacial infections who were admitted during the coronavirus disease 2019 (COVID-19) pandemic period in a single, point of reference center in Northern Greeceas well as analyze the quantitative and qualitative parameters of patient characteristics and management data. This was a retrospective cohort study that included all the patients with cervicofacial infections who were admitted to our unit during the COVID-19 pandemic, specificallybetween 2020 and 2021. For comparative reasons, patients admitted with cervicofacial infections between 2019 and 2020 (pre-COVID period) were analyzed. In total, 341 patients fulfilled the criteria for this study. Specifically, the number of admitted patients was 151 in the pre-COVID era instead of 190 patients in the pandemic. The mean age of the patients was 45.3 years, with a slight male predominance (54.7% males to 45.3%). The mean duration of hospitalization was 2.5 days in the pre-COVID period instead of 3.42 days in the pandemic. Interestingly, in the pandemic, eight times more patients were admitted to the ICU post-operatively, in contrast to the pre-COVID period (23 vs 3 patients). Also in the COVID period, almost 54.9% of the patients presented with fever and 49.6% with trismus. Moreover, the submandibular space involvement was the most common space of infection in both COVID and pre-COVID groups with (58.9% and 49.7%) respectively.In one-third of all cases, a post-extraction infection of a third molar was the main cause of abscess. Cervicofacial infections during the COVID-19 pandemic appeared with more severe symptoms and resulted in an increased number of patients who needed admittance to the intensive care unit, in contrast to the pre-COVID era. Also, the mean length of stay was increased for a day at the same period. This study could be used as an example for further research, in case of similar pandemic situations in the future.

Profile of Patients with Maxillofacial Space Infections and Associated Risk Factors.

To evaluate the profile of patients operated for maxillofacial space infections and associated risk factors for the length of hospital stay. We conducted a retrospective study among patients operated for maxillofacial infections at our center from 2010 to 2020. Information collected from the records were age, sex, type and number of spaces involved, clinical signs and symptoms (pain, swelling, toothache, sore throat, otalgia, hoarseness, headache, cough, neck swelling, rancid breath, sialorrhea, gingival swelling, muffled voice, trismus, fever, dysphagia, odynophagia, malaise, lymphadenopathy, dyspnoea, pus discharge), treatment modality, total leukocyte count, evidence of bacterial growth, comorbidities, complications if any and length of hospital stay. A total of 128 medical records were examined, out of which 59 were female. The mean age was 38.59 ± 19.7 and the length of hospital stay was 7.56 ± 3.8 days. The most commonly involved space was submandibular space (46.1%) and the common symptoms reported were swelling (99.2%), pain (86.7%), and trismus (68%). Four patients had complications like necrotizing fasciitis (1.6%), pneumonia (0.8%), and death in one patient (0.8%). Logistic regression showed that patients more than 36 years of age, male sex, evidence of bacterial growth, and diabetics had higher odds of increased hospital stay (>6 days). Multiple logistic regression analysis showed that age (P = 0.015; OR: 2.98) and evidence of bacterial culture (P = 0.001; OR:6.64) were potential predictors associated with increased hospital stay. Our study showed that the age of the patient and evidence of bacterial culture were potential predictors of prolonged hospital stay among patients operated for maxillofacial space infections.

Submandibular abscess in a pregnant patient with multiple antibiotic allergies: A case report

Objective: This article describes and discusses the management of submandibular abscesses in pregnant women with allergies to several antibiotics. Case Report: A 34-year-old pregnant female patient came to the dental clinic with complaints of swelling and pain in her left cheek and difficulty in opening her jaw. The patient was diagnosed with a left submandibular abscess. Result: The doctor performed an odontectomy and extracted the remaining roots, which were suspected to be the cause of the abscess. The patient was also advised to visit the emergency room at Brawijaya University Hospital for further treatment after coamoxiclav failed to alleviate the symptoms. Conclusion: This case reports a dramatic course of treatment in a pregnant patient with a submandibular abscess accompanied by allergies to several antibiotics. Surgical intervention in pregnant women requires appropriate clinical considerations and guidelines to prevent complications.

Parotid Lipomas: Case Series and Literature Review – A Case Report

Background: Lipomas are the most frequent neoplasm of mesenchymal origin in the head-and-neck region. Around 15% of lipomas are found in the head-and-neck region. The usual site where lipomas can be found in the head-and-neck region is in the posterior triangle of the neck but they can also be found in the anterior neck, infratemporal fossa, submandibular space, larynx, pharynx, and parotid gland. The incidence of parotid lipoma ranges from 0.6% to 4.4% of all parotid neoplasms. There are two histological variants, focal lipoma and diffuse infiltrating variant. We describe two cases of rare focal lipoma of the parotid gland, therefore, must be reported. As rare as it may appear, existing relevant literature suggest management to includes definitive radiological investigations such as magnetic resonance imaging (MRI) and complete removal of lipoma with or without a cuff of parotid tissue. Case Report: Two cases were identified with a parotid lipoma on final histology. Case 1 is a 57-year-old male with a history of painless left parotid swelling for 2 years, reported to be 5 cm × 4 cm size on ultrasound, therefore, underwent superficial parotidectomy. Case 2 is a 67-year-old male who presented with right parotid swelling for 15 years, reported on ultrasound to be 5 cm × 5 cm, and underwent excision of intraparotid tumor. He later went on to develop breast carcinoma. The facial nerve was intact of both patients. Conclusion: Parotid lipomas are rare entities that should be a differential for clinically soft parotid swellings. Management includes definitive radiological investigations such as MRI and complete removal of lipoma with or without a cuff of parotid tissue instead of regular ultrasound followed by fine-needle aspiration cytology. Although our cases were managed on the same regular outlines, but reporting these cases would suffice the potential role of MRI and computed tomography scan for parotid swelling as per existing literature.

Neutrophil to lymphocyte ratio in odontogenic infection: a systematic review

BackgroundWe conducted this systematic review to compile the evidence for the role of neutrophil to lymphocyte ratio (NLR) in odontogenic infection (OI) and to determine whether NLR is elevated in patients with OI. This was done to aid physicians in better understanding this condition for clinical management.MethodsThe search was conducted on PubMed, Scopus, and Web of Science libraries on March 30, 2023. Two reviewers independently screened the studies using Endnote software. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the studies.ResultsA total of nine studies were included in the review. Among patients with OI, positive and statistically significant correlations of NLR were seen with more severe disease, a prolonged hospital stay, postoperative requirement of antibiotics, and total antibiotic dose needed. In the receiver operating characteristics (ROC) analysis, the optimum cut–off level of NLR was 5.19 (specificity: 81, sensitivity: 51). In addition, NLR was correlated with preoperative fever (p = 0.001). Among patients with Ludwig’s Angina, NLR could predict disease severity and length of stay in the hospital (p = 0.032 and p = 0.033, respectively). In addition, the relationship between the NLR and mortality was statistically significant (p = 0.026, specificity of 55.5%, and sensitivity of 70.8%). Among patients with severe oral and maxillofacial space infection, a positive correlation was found between IL-6 and CRP with NLR (rs = 0.773, P = 0.005 and rs = 0.556, P = 0.020, respectively). Also, a higher NLR was considered an essential predictor of organ involvement (P = 0.027) and the number of complications (P = 0.001). However, among diabetes mellitus (DM) patients afflicted with submandibular abscesses, NLR had no association with therapeutic response.ConclusionsMany people around the world suffer from OI, and a cheap and fast biomarker is needed for it. Interestingly, inflammation plays a role in this infection, and elevated NLR levels can be a good biomarker of inflammation and, as a result, for OI progression.

Are Deep Odontogenic Infections Associated With an Increased Risk for Sepsis?

Quick Sequential Organ Failure Assessment (qSOFA) is recommended to identify sepsis. Odontogenic infection (OI) can progress to sepsis, causing systematic inflammatory complications or organ failure. The purpose of the study was to measure the association between OI location and risk for sepsis at admission. This retrospective cohort study included subjects treated for OI at Baylor University Medical Center in Dallas, TX, from January 9, 2019 to July 30, 2022. Subjects > 18years old who were treated under general anesthesia were included. OI limited to periapical, vestibular, buccal, and/or canine spaces were excluded from the sample. The primary predictor variable was OI anatomic location (superficial or deep). Superficial OI infection includes submental, submandibular, sublingual, submasseteric, and/or superficial temporal spaces. Deep OI includes pterygomandibular, deep temporal, lateral pharyngeal, retropharyngeal, pretracheal, and/or prevertebral. The primary outcome variable was risk for sepsis measured using a qSOFA score (0 to 3). A higher score (>0) indicates the patient has a high risk for sepsis. Covariates were demographics, clinical, laboratory, and radiological findings, antibiotic route, postoperative endotracheal intubation, tracheostomy, intensive care unit, admission, and length of stay. Descriptive and bivariate analyses were performed. A χ2 test was used for categorical variables. The Mann-Whitney U test was used for continuous variables. Statistical significance was P<.05. The sample was composed of 168 subjects with a mean age of 42.8±21.5 and 69 (48.6%) subjects were male. There were 11 (6.5%) subjects with a qSOFA score > 0. The relative risk of a qSOFA > 0 for a deep OI is 5.4 times greater than for a superficial OI (136 (95.8) versus 21 (80.8%): RR (95% confidence interval): 5.4 (1.51 to 19.27), P=.004). After adjusting for age, sex, American Society of Anesthesiologists score, and involved anatomical spaces, there was a significant correlation between laterality and the number of involved anatomical spaces and qSOFA score (odd ratio=9.13, 95% confidence interval: 2.48 to 33.55, adjusted P= <.001). The study findings suggest that the OI location is associated with the qSOFA score >0.

A giant dermoid cyst in the floor of the mouth: a case report

Dermoid cysts are slow-growing cystic masses that are lined by stratified squamous epithelium and contain skin appendages. Dermoid cysts in the floor of the mouth account for less than 0.01% of all neck and oral cavity cysts. They can be either congenital or acquired. We report a case of a 25-year-old male, a final-year engineering student, who came to our outpatient department with complaints of swelling in the mouth and weight loss for 4 years. On examination, a large cystic swelling in the floor of the mouth, approx. 5x6 cm, obscuring the oropharynx, was seen. USG and CECT of the neck suggested ranula and plunging ranula in the right submandibular space, respectively. He underwent a combined (debulking and enucleation) submandibular cystic swelling excision through a transoral approach under general anesthesia guided by awake fiber optic nasal intubation. The intraoperative and postoperative periods were uneventful. Histopathologic examination of the resected tissue specimen suggested a dermoid cyst. The patient recovered well during the 1-month follow-up, and he gained weight up to 2.5 kg in a month of treatment. Dermoid cysts are very rare cystic lesions on the floor of the mouth. Surgery is the most curable method of treatment. A proper clinical examination with imaging guidance is necessary for accurate delineation of the cyst. Large submandibular cystic lesions can be excised by combining debulking and enucleation through a transoral approach, with a good cosmetic and functional outcome.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy.
