Management of cervicofacial infections: a survey of current practice in maxillofacial units in the UK

Is Postoperative Steroid Use Associated With Improved Outcomes in Severe Odontogenic Infections?

BACKGROUND

The use of steroids as an adjunctive therapy in odontogenic infections is common, but few studies have focused on the effect of steroids in improving outcomes in these infections.

PURPOSE

The purpose of the study was to measure the association between postoperative steroid use and length of stay (LOS) and reoperation among patients with severe odontogenic infections.

STUDY DESIGN, SETTING, SAMPLE

The authors conducted a prospective cohort study consisting of all adult patients treated in the operating room for an odontogenic infection from August 1, 2019, to December 31, 2022, at University Medical Center of New Orleans. Patients were excluded if an odontogenic source could not be confirmed.

PREDICTOR VARIABLE

The predictor variable was the use of steroids postoperatively (after conclusion of surgery until discharge), coded as a yes or no.

MAIN OUTCOME VARIABLE

The outcome variables were total LOS, postsurgical LOS, and reoperation.

COVARIATES

The covariates were demographics, medical history, exam findings, diagnosis, and treatment-related variables.

ANALYSES

Descriptive and bivariate analyses were performed, as well as linear regression analyses. A P value of ≤ .05 was considered significant.

RESULTS

The study sample consisted of 240 patients with a mean age of 40.3 ± 14.5 years and a sex distribution of 57.5% (138) male and 42.5% (102) female. Steroids were used in 114 patients (47.5%) postoperatively. The mean total LOS and postsurgical LOS were 3.7 ± 2.4 days and 3.1 ± 2.4 days, respectively. Reoperation was performed for 12 (5.0%) patients. Postoperative steroid use group was not significantly associated with total LOS (3.7 ± 2.6 days vs 3.6 ± 2.2 days, P = .59), postsurgical LOS (3.3 ± 2.6 days vs 2.9 ± 2.1 days, P = .13), or reoperation (58.3 vs 41.7%, P = .56) for the group that received steroids versus those that did not, respectively.

CONCLUSIONS AND RELEVANCE

Postoperative steroid use was not associated with reduced LOS, postsurgical LOS, or reoperation in patients with severe odontogenic infections.

Update on Antimicrobial Therapy in Management of Acute Odontogenic Infection in Oral and Maxillofacial Surgery

This article focuses on the antimicrobial therapy of head and neck infections from odontogenic origin. Odontogenic infections are among the most common infections of the oral cavity. They are sourced primarily from dental caries and periodontal disease (gingivitis and periodontitis). Many odontogenic infections are self-limiting and may drain spontaneously. However, these infections may drain into the anatomic spaces adjacent to the oral cavity and spread along the contiguous facial planes, leading to more serious infections. Antibiotics are an important aspect of care of the patient with an acute odontogenic infection. Antibiotics are not a substitute for definitive surgical management.

Clinical features and presentation of cervicofacial infection: a Maxillofacial Trainee Research Collaborative (MTReC) study

Cervicofacial infection (CFI) is a common presentation to the Oral and Maxillofacial (OMFS) department and accounts for significant emergency activity. The current study aims to understand the aetiology, management, and clinical features of patients hospitalised with CFI. Our study included all patients admitted for management of CFI from May to October 2017 at 25 OMFS units across 17 UK regions. Data were collected prospectively and included age, comorbidities, prior treatment received, markers of sepsis, and presenting clinical features. One thousand and two (1002) admissions were recorded; 546 (54.5%) were male. Median (range) age was 34 (1-94) years. The most common presenting complaints were trismus (46%) and dysphagia (27%). Airway compromise was present in 1.7% of cases. Odontogenic infection accounted for 822/1002 (82%) admissions. Of those with an infection of odontogenic origin, 453/822 (55.1%) had received previous treatment. Two-thirds of those who had received treatment were managed by antibiotics alone (300/453, 66.2%). Patients met criteria for sepsis in 437/1002 (43.6%) of CFI, and in 374/822 (45.5%) of odontogenic infections. This is the largest study worldwide of patients requiring inpatient management for CFI. Infection due to odontogenic origin is the most frequent reason for admission and nearly half do not seek treatment before presentation. Patients with CFI often present late in their disease and frequently meet criteria for sepsis, requiring timely and aggressive treatment to ensure optimum outcomes. Trismus is an emerging dominant feature with all the implications related to the anaesthetic management of these patients. Knowledge of these factors has implications for the referrer, triage, the emergency department, the anaesthetic team, and members of the OMFS team.

Gender differences in patients with severe dental infections presenting to hospital

Introduction Gender differences have been documented in prevalence and morbidity of caries, gingivitis and oral health, but not previously in cervicofacial infection. Identification and minimisation of gender inequalities is a World Health Organisation priority, and there are physiological, behavioural and cultural reasons to suspect that sex and gender differences may be present.Methods Analysis was carried out of the MTReC National Snapshot audit of cervicofacial infections. This database was created by oral and maxillofacial surgery trainees in 2017 and records over 400 variables in 1,002 individual patients admitted to hospital with severe odontogenic infection.Results Records were available for 1,002 patients with cervicofacial infection (456 females and 546 males). There were significant differences between recorded gender in those presenting with airway compromise (male 7% vs female 2%, p = 0.001), severe inflammatory response syndrome (male 60% vs female 39%, p = 0.007) and requirement for awake fibre-optic intubation on admission (male 4% vs female 1%, p = 0.014).Discussion These results suggest that male patients access healthcare later in their disease than female patients, and with more severe systemic compromise. This may be due to prevalent cultural and behavioural norms. As equality of access is the responsibility of the administrator, we discuss methods which might improve timely presentation in males with cervicofacial infections.

The use of steroids in cervicofacial infections in UK OMFS departments: a Maxillofacial Surgery Trainees Research Collaborative (MTReC) study

INTRODUCTION

Defining current inpatient management of cervicofacial infections is key to identifying strategies to optimise care. Steroid use is beneficial in peritonsillar and orbital abscess, but there are few studies of steroid use in odontogenic cervicofacial infections. Our previous research identified widespread variation in practice, necessitating a national audit to define current practice.

METHODS

A multicentre, trainee-led snapshot audit was carried out across 25 hospitals in the UK. Information recorded included demographic features, presentation, surgical and medical management, and steroid administration.

RESULTS

One thousand two admissions were recorded. Fifty-five percent were male, with mean age 37.3 years (range 0-94 years). Steroids were administered to 357 patients (36%), 159 of whom received steroids on admission, and 254 peri-operatively. Patients who were prescribed steroids had significantly higher white cell count (12.4 vs 11.5), CRP (79.5 vs 57) and heart rate (94 vs 88) on admission. Justifications given for administration included swelling (74), dysphagia (21), and airway compromise (7). Three patients (0.8%) reported steroid-related side effects.

CONCLUSIONS

This study uses the largest recorded cohort of cervicofacial infections to define current inpatient steroid administration. Our results suggest that steroids are targeted towards the most compromised 1/3 of patients. The incidence of steroid-related side effects was low. Defining the characteristics of patients currently receiving steroids will aid in determining whether steroid administration is an effective adjunct in treating odontogenic cervicofacial infection.

Impacts of lockdown during the SARS-CoV-2 pandemic on patients presenting with cervicofacial infection of odontogenic origin: a comparative study

The SARS-CoV-2 pandemic caused unprecedented disruption to primary and secondary healthcare services. Our aim was to explore whether the pandemic had had any impact on patients presenting with cervicofacial infections (CFI) of odontogenic origin to secondary care and management. Comparative analysis was carried out evaluating prospective and retrospective consecutively admitted patients with a diagnosis of CFI of odontogenic origin in the COVID-19 lockdown period from 15 March to 15 June 2020 and pre-COVID-19 during the same period of the previous year. Data included patients' demographics, comorbidities, systemic inflammatory response syndrome (SIRS) status on admission, clinical features, prior treatment in primary care, source of referral, SARS-COV-2 antigen status, treatment received in secondary care, intraoperative findings, and whether escalation of the level of care was required. Across both cohorts there were one hundred and twenty-five (125) patients admitted with CFI of odontogenic origin, with a 33% reduction (n=75 (2019) vs n=50 (2020)) in number of patients admitted during COVID-19 lockdown. There was no difference between the cohorts in terms of age (p=0.192), gender (p=0.609) or major comorbidities (p=0.654). Proportionally more patients in the COVID-19 group presented with SIRS (p=0.004). This group of patients persisted with symptoms for longer before presenting to secondary care (p=0.003), more delay from hospital admission to surgical intervention (p<0.005) and had longer hospital stays (p=0.001). More patients required extraoral surgical drainage during COVID-19 (p=0.056). This study suggests that the COVID-19 lockdown has had adverse effects on the presentation of CFI of odontogenic origin and its management within a Regional Acute Maxillofacial Service. Commissioners and clinicians should endeavour to plan for adequate primary and secondary care provision during any future local lockdowns to ensure that patient care is optimised.

Aerobic and anaerobic microorganisms and antibiotic sensitivity of odontogenic maxillofacial infections

This study aimed to identify the aerobic and anaerobic causal microorganisms of odontogenic infections and their antibiotic sensitivity. Purulent exudates were taken from patients with odontogenic infections by transdermal puncture, and aerobic and anaerobic microorganisms were identified using biochemical tests. Susceptibility to antibiotics was tested using the Kirby-Bauer method; the inhibition halos were measured according to NCCLS, and based on the results, the microorganisms were classified as susceptible, intermediate or resistant to each antibiotic. Frequencies of species and percentages of resistance were calculated. The microorganisms associated with odontogenic infections were principally anaerobic (65.3% anaerobic vs. 35.7% aerobic), and the susceptibility to antibiotics was higher in anaerobic than in aerobic microorganisms. The majority of isolated microorganisms (82%) showed susceptibility to amoxicillin/clavulanic acid. The causal agents of odontogenic infections were anaerobic microorganisms, which exhibited high resistance to antibiotics.
