Cavernous Sinus Involvement and Near Miss Mediastinitis following Mandibular Tooth Infection Treated during the COVID-19 Pandemic: Clinical Diagnosis and Treatment

Odontogenic infections represent a frequent condition that in some cases, if not treated promptly, can spread quickly to the rest of the body and turn into life-threatening infections. In this work, the case is reported of a 59-year-old woman, diabetic and overweight, who presented to the Odontostomatology and Otolaryngology Section of the Policlinic of Bari with mandibular tooth infection that had developed into a deep neck space infection leading to the involvement of cavernous sinuses and near mediastinum. The diagnosis, the surgical drainage of the phlegmon and removal of infection foci, appropriate control of the airways, and a correct antibiotic therapy made it possible to avoid a potentially fatal condition. Prompt management and early diagnosis of deep space neck infections, such as phlegmon and/or necrotizing fasciitis, with the auxilium of CT scans and tools such as LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis), NLR (Neutrophil-to-Lymphocyte Ratio), and LRINECxNLR scores (Laboratory Risk Indicator for Necrotizing Fasciitis and Neutrophil to Lymphocyte Ratio), are advised to evade delays and complications that could potentially worsen the patient’s outcome.

Ludwig's angina in Nigeria: The disease of the poor and health inequality!

AIM

highlight the health inequality and identify opportunities to improve the care delivered to the patients who suffer from Ludwig's angina which could have national and international clinical impact.

MATERIALS AND METHODS

Data was collected from three major oral and maxillofacial centers, in Nigeria including Benin, Lagos and Kano. A protocol was developed for data collection which included demographic details, socio-economic status, management of the air way, the associated morbidities and mortalities.

RESULTS

Forty-nine were managed in Benin, 57 in Lagos and 66 in Kano. Diabetes was the most prevalent underlying systematic condition, affecting 21% of the Ludwig's angina patients in Lagos. Poverty was a common denominator, 90% of the patients from Kano were unemployed compared to 23% and 8% from Lagos and Benin respectively. For most of the patients, the airway was monitored. Incision and drainage were carried out in most of the cases at Benin and Lagos, but it was only considered in 50% of the cases in Kano. Mortality ranged from 4% in Benin to 12% in Lagos and it was as high as 19% in Kano.

CONCLUSION

poor access to oral healthcare, unemployment and low socio-economic status are important predisposing factors of Ludwig's angina.

Cervicofacial necrotizing fasciitis among patients attending the Muhimbili National Hospital, Dar es Salaam, Tanzania

BACKGROUND

Cervicofacial necrotizing fasciitis (NF) is a rare life-threatening infection in the head and neck region that characteristically spreads along the fascial planes to involve subcutaneous tissues, fascia and fat, however, in late stages it can involve muscles and skin. The aim of this study was to determine the occurrence of cervicofacial NF among patients attending treatment at the Muhimbili National Hospital (MNH).

METHODS

This was a prospective descriptive cross-sectional hospital-based study which was carried at Muhimbili National Hospital (MNH) from May 2013 to April 2014. It included 42 patients with cervicofacial NF. They were interviewed for demographic information, chief complaints, symptoms, duration and treatment received before reporting at MNH. A thorough assessment of general health condition of the patients and laboratory investigations were followed by management according to MNH protocol. Data obtained from these patients were analyzed using Statistical Package for Social Sciences SPSS 20.

RESULTS

During the study period, 151 patients reported at MNH with odontogenic infections. A total of 42 (27.8%) patients satisfied our diagnostic criteria for cervicofacial NF. The age range was 15 years to 83 years (mean 43.95, SD +/- 16.16). Greater (35.7%) proportion was in the age group of 30-39 years with 31 (73.8%) males and 11 (27.2%) females making a male to female ratio of 2.8:1. Fifteen (35.7%) patients had at least one co-existing systemic condition, which included anaemia in 5 (11.9%) patients, followed by diabetes mellitus (DM) and malnutrition 4 (9.5%) patients each and HIV infection 2 (4.8%) patients. Others were combination of; HIV infection and malnutrition, HIV infection and anaemia and diabetes mellitus and anaemia each in one (2.4%) patient. There was a mortality of 42.9% comprising of 14 (33.3%) males and 4 (9.6%) females.

CONCLUSIONS

Cervicofacial NF is a polymicrobial infection, requiring surgery, antibiotics and management of co-existing systemic conditions. Anaemia, diabetes mellitus and malnutrition were the main co-existing systemic conditions. The rather high mortality was mainly attributable to late reporting.

Cervicofacial Necrotizing Fasciitis in Patients with No Underlying Medical Conditions: A Review of Four Cases Seen in Twelve Months at a Nigerian Tertiary Hospital

Necrotizing fasciitis of the head and neck is a rare but rapidly progressive infection involving the skin, subcutaneous tissue, and fascia. We report 4 cases of cervicofacial necrotizing fasciitis with similar patterns of presentation. All the 4 cases presented with an odontogenic source and no underlying medical condition. All the patients had tooth extraction and serial wound debridement. Three of these patients recovered well, and healing of the wound occurred by secondary intention. One patient had a resultant neck defect, which was repaired with a supraclavicular island flap after the infection had subsided. We advocate the importance of early detection of necrotizing fasciitis with or without an underlying medical condition and an aggressive medical and surgical intervention. Additionally, eradication of the source of infection is highly indicated to reduce the mortality of this disease.

Hyperbaric oxygen may only be optional in head and neck necrotizing fasciitis: a retrospective analysis of 43 cases and review of the literature

BACKGROUND

Necrotizing fasciitis in the head and neck (NF-HN) is a rare and potentially life-threatening condition. The use of hyperbaric oxygen therapy (HBOT) in the acute regimen is disputed and there is a lack of evidence of therapeutic effect. This study aims to describe a retrospective cohort of patients with NF-HN and investigate the use of HBOT and consequences thereof.

METHODS

All patients treated for NF-HN at Aarhus University Hospital (AUH) between 2002 and 2014 were included in this retrospective cohort. Data regarding demographics, treatment and a one-year follow-up was registered. A review of the literature on NF-HN and HBOT was performed.

RESULTS

Forty-three patients were consecutively treated for NF-HN during the period. All patients were treated in accordance with current guidelines with HBOT as a variable. Thirty patients received HBOT, and 13 patients were omitted from HBOT for different reasons. In the HBOT group were no mortalities vs. three mortalities in the non-HBOT group two late deaths due to precursory underlying cancer of the head and neck, and one early death shortly after admittance. We found higher rates of complications (63% vs. 25%) and sequelae (77% vs. 40%) among the HBOT group compared to the non-HBOT group.

CONCLUSIONS

Our findings suggest that HBOT for NF-HN may only be optional and that the decision relies on an individual assessment of each patient. Further research is needed concerning the evidence of HBOT and towards selecting the patients benefitting from HBOT.

Cervical Necrotizing Fasciitis: A Potentially Fatal Disease with Varied Etiology

Necrotizing fasciitis was recognized centuries ago by physicians. It is a rapidly progressive and potentially fatal soft-tissue infection that is typified by soft-tissue necrosis, especially affecting the subcutaneous tissues and fascia. Cervico-facial necrotizing fasciitis is said to be uncommon, but when it occurs, it is often of odontogenic origin and has severe consequences if not promptly treated. Possible underlying systemic diseases and the source of infection should be addressed and treated appropriately. We present two cases of extensive cervicofacial necrotizing fasciitis, one of which was idiopathic in origin and the other with gross involvement of the chest and abdominal walls. Both were treated successfully. Immediate resuscitation of the patients, administration of empirical antibiotics, treatment of underlying systemic conditions and early, aggressive and serial debridement were the bedrock of management in these cases.

Clinical Parameters and Challenges of Managing Cervicofacial Necrotizing Fasciitis in a Sub-Saharan Tertiary Hospital

INTRODUCTION

Necrotizing fasciitis is a severe soft tissue infection. In our environment, patients presenting with this infection are usually financially incapacitated and, therefore, their management can be challenging. This paper aimed to document the pattern and challenges encountered in the management of cervicofacial necrotizing fasciitis (CNF) in the University College Hospital, Ibadan.

MATERIALS AND METHODS

Information such as biodata, site of infection, systemic conditions, widest span of defect, management provided, hospital stay, and outcome of management was prospectively collected on all patients with CNF who presented at the Department of Oral and Maxillofacial Surgery between January 2007 and December 2013. The patients were managed according to a devised protocol of antibiotic therapy, serial debridement and honey dressings.

RESULTS

Twenty-four cases of CNF were seen. There were 9 males and 15 females while 70.9% of the patients belonged to the low socioeconomic class. The mean span of wound defect was 12.2 (±8.844) cm. The mean hospital stay was 27.8 (±23.1) days, and scar formation was the most common complication encountered.

CONCLUSION

Our study represents the largest series of CNF from a Nigerian health facility presently. The management of necrotizing fascitis in the maxillofacial region poses a significant challenge to both the surgeon and the patient. However, the mortality rate of CNF in our center appears comparatively low.

Management and maintenance of the airway in cervical necrotising fasciitis: a retrospective analysis of 15 cases

Cervical necrotising fasciitis is a progressive deep infection of the neck associated with high mortality, and skillful management of the airway is critical for operations under general anaesthesia. Tracheostomy under local anaesthesia has been considered the gold standard of airway management in patients with deep neck infections, but it may be difficult or impossible in advanced cases. We report here our experience over 6 years (January 2008 and December 2013) during which a total of 15 patients was diagnosed with cervical necrotising fasciitis. Of 6 patients, admitted between January 2008 and March 2010, 5 had routine tracheostomy under local anaesthesia, 1 had direct laryngoscopy intubation, and 9 who were admitted between Spring 2010 and December 2013 were treated with nasotracheal intubation. Postoperatively all patients were given moderate sedation and analgesia. Nasotracheal intubation was continued until the infection had been controlled. During intubation patency of the endotracheal tube was maintained by humidification with a continuous pump of 0.45% sodium chloride and suction. All 15 patients (10 men and 5 women, mean age 62 years, range 36-93) required an emergency drainage procedure under general anaesthesia. Fourteen of the 15 had evidence of compromise of the airway, but emergency intervention was not required. Since Spring 2010, 9 consecutive patients had required nasotracheal intubation, including 7 video laryngoscopies and 2 fibreoptic bronchoscopies. No other interventions were required. Patients were intubated postoperatively from 3 to 14 days, and there were no problems with the airway. Advanced techniques for control of the airway have a high rate of success in patients with necrotising fasciitis and could be an appropriate alternative to a traditional airway. Postoperative sedation and analgesia should be considered as routine management of pain and anxiety.

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.

Acute inflammation in horizontal incompletely impacted third molar with radiolucency in the elderly

Although radiolucency has been shown as a risk of infection, the poorly understood effects of aging on radiolucency correlate with acute pericoronitis, which has a high risk of infection extending any complications. We reviewed the records of 346 consecutive patients aged more than 41 years to evaluate whether pericoronal radiolucency below the crown in mandibular horizontal incompletely impacted third molars is related to acute inflammation. The frequency of acute inflammation in teeth with pericoronal radiolucency below the crown was similar to that in teeth without; however, the odds ratio of acute inflammation exhibited in women aged more than 61 years compared to women aged 41–50 years was 9.77 (95% confidence interval [CI]: 1.67–57.29; P < <0.05), and in women aged more than 61 years compared to women aged 51–60 years was 26.25 (95% CI: 2.94–234.38; P < 0.01). The odds ratio of severe acute inflammation exhibited in men aged more than 61 years compared to men aged 41–50 years was 16.67 (95% CI: 1.76–158.27; P < 0.01). These odds ratios indicate an association of acute pericoronitis, including the severe forms of acute inflammation that result from pericoronitis, with pericoronal radiolucency below the crown in the elderly.

Radiolucency below the crown of mandibular horizontal incompletely impacted third molars and acute inflammation in men with diabetes

Although mandibular third molar has a high risk of infection extending any complications, the influence of diabetes on radiolucency and acute inflammation in pericoronitis remains unclear. The present study was to evaluate whether radiolucency below the crown is related to acute inflammation in mandibular horizontal incompletely impacted third molars and to review the records of 140 men more than 45 years with and without diabetes. The odds ratio of exhibiting acute inflammation was 3.38 (95% CI: 1.13-10.16, p < 0.05) and that of exhibiting severe acute inflammation was 15.38 (95% CI: 3.56-66.49, p < 0.0001), indicating an association of acute pericoronitis in diabetes. The frequency of radiolucency below the crown and below the root in diabetics was similar to that in nondiabetics. However, the odds ratio of exhibiting both radiolucency below the crown and acute inflammation under the diabetic condition was 4.85 (95% CI: 1.60-14.73, p < 0.01), whereas that of diabetics showing both radiolucency below the root and acute inflammation was 0.46 (95% CI: 0.06-3.74, p = 0.74). Radiolucency below the crown and acute inflammation were associated with diabetes, but that below root and acute inflammation were not associated with diabetes, indicating that the region below the crown carries susceptibility to acute pericoronitis, whereas the periodontium shows a protective effect against acute pericoronitis.

Update on general health risk of periodontal disease

OBJECTIVES

To review the potential of periodontal infections to cause nonoral diseases. Therapeutic recommendations are provided to help patients and dental practitioners prevent systemic complications from periodontal infections.

FINDINGS

Systemic diseases from oral bacteria are mostly caused by transient bacteraemias, which can occur spontaneously from dental foci of infection, from mastication, brushing, flossing or other daily manipulations, or from dental treatments. Examples of systemic infections that may involve oral microorganisms include infective endocarditis, aspiration pneumonia, HIV-related disseminated candidiasis and cancrum oris, septicaemia associated with cancer chemotherapy and radiotherapy, necrotising faciitis and various other life-threatening infections. Inflamed gingiva constitutes a significant reservoir for herpes viruses, which have the potential to cause serious systemic diseases in immunocompromised patients. Periodontal disease may also aggravate chronic insulin insensitivity and thus interfere with glycaemic control in diabetic patients. Controversy surrounds the involvement of periodontal infections in coronary heart disease.

CONCLUSIONS

Cumulative evidence suggests that periodontal disease can be an important cause of morbidity and mortality of various systemic diseases, especially in individuals exhibiting compromised host defence. Maintaining a healthy dentition and periodontium by means of daily oral hygiene practice and regular professional care is the most effective way of preventing systemic diseases from oral infections.
