Sakkas A, Weiß C, Zink W, Rodriguez CA, Scheurer M, Pietzka S, Wilde F, Thiele OC, Mischkowski RA, Ebeling M. Airway Management of Orofacial Infections Originating in the Mandible. J Pers Med 2023; 13:950. [PMID: 37373939 DOI: 10.3390/jpm13060950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 05/31/2023] [Accepted: 06/02/2023] [Indexed: 06/29/2023] Open
Abstract
The primary aim of this study was to assess the incidence of a difficult airway and emergency tracheostomy in patients with orofacial infections originating in the mandible, and a secondary aim was to determine the potential predictors of difficult intubation. This retrospective single-center study included all patients who were referred between 2015 and 2022 with an orofacial infection originating in the mandible and who were surgically drained under intubation anesthesia. The incidence of a difficult airway regarding ventilation, laryngoscopy, and intubation was analyzed descriptively. Associations between potential influencing factors and difficult intubation were examined via multivariable analysis. A total of 361 patients (mean age: 47.7 years) were included in the analysis. A difficult airway was present in 121/361 (33.5%) patients. Difficult intubation was most common in patients with infections of the massetericomandibular space (42.6%), followed by infections of the mouth floor (40%) and pterygomandibular space (23.5%). Dyspnea and stridor were not associated with the localization of infection (p = 0.6486/p = 0.4418). Multivariable analysis revealed increased age, restricted mouth opening, higher Mallampati scores, and higher Cormack-Lehane classification grades as significant predictors of difficult intubation. Higher BMI, dysphagia, dyspnea, stridor and a non-palpable mandibular rim did not influence the airway management. Patients with a difficult airway were more likely to be admitted to the ICU after surgery than patients with regular airway were (p = 0.0001). To conclude, the incidence of a difficult airway was high in patients with orofacial infections originating in the mandible. Older age, limited mouth opening, a higher Mallampati score, and a higher Cormack-Lehane grade were reliable predictors of difficult intubation.

Head Face Med 2023; 19:10. [PMID: 36922880 PMCID: PMC10015701 DOI: 10.1186/s13005-023-00354-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 02/24/2023] [Indexed: 03/17/2023] Open
Abstract
BACKGROUND Different bacterial infections of the oro-naso-pharyngeal (ONP) region may progress and require hospital care. The present study clarified differences in infection characteristics between hospitalized patients with odontogenic infections (OIs) and other bacterial ONP infections. The specific aim was to evaluate clinical infection variables and infection severity according to infection aetiology, particularly regarding features of OIs compared with other ONPs. METHODS Records of patients aged ≥16 years requiring hospital care for an acute bacterial ONP infection in the emergency units of Otorhinolaryngology or Oral and Maxillofacial Surgery at the Helsinki University Hospital (Helsinki, Finland) during 2019 were evaluated retrospectively. The main outcome variables were need for intensive care unit (ICU) treatment and length of hospital stay. The primary predictor variable was infection category, defined as OI or other ONP. The secondary predictor variable was specific ONP infection group. Additional predictor variables were primary clinical infection signs, infection parameters at hospital admission, and delay from beginning of symptoms to hospitalization. Explanatory variables were sex, age, current smoking, heavy alcohol use or substance abuse, and immunosuppressive disease, immunosuppressive medication, or both. Comparison of study groups was performed using Fisher's exact test, student's t-test, and Mann-Whitney U. RESULTS A total of 415 patients with bacterial ONPs fulfilled the inclusion criteria. The most common infections were oropharyngeal (including peritonsillar, tonsillar, and parapharyngeal infections; 51%) followed by infections from the odontogenic origin (24%). Clinical features of OIs differed from other ONPs. Restricted mouth opening, skin redness, or facial or neck swelling (or both) were found significantly more often in OIs (p < 0.001). OIs required ICU care significantly more often than other ONPs (p < 0.001) and their hospital stay was longer (p = 0.017). CONCLUSIONS Infections originating from the tonsillary and dental origin had the greatest need for hospitalization. Clinical features of OIs differed; the need for ICU treatment was more common and hospital stay was longer compared with other ONPs. Preventive care should be emphasized regarding OIs, and typical infection characteristics of ONP infection subgroups should be highlighted to achieve early and prompt diagnosis and treatment and to reduce hospitalization time.

Abstract
BACKGROUND Infectious diseases are common in pediatric patients. In these patients, ultrasound is a useful imaging modality that involves no irradiation or sedation and can be performed repeatedly at the patient's bedside. The purpose of this review was to show pediatric cases with infectious disease that used ultrasound to decide the methods of treatment. DATA SOURCES Literature review was performed using Pubmed as the medical database source. No year-of-publication restriction was placed. The mesh terms used were: "ultrasound", "sonography", "infectious disease", "treatment", "antibiotics", "surgical intervention", "pediatric", "children", "deep neck abscess", "pyothorax", "empyema", "pneumonia", "urinary tract infection", "intra-abdominal abscess", "soft tissue infection", "septic arthritis", "osteomyelitis", and "surgical site infection". RESULTS We presented pediatric case series with infectious diseases, including deep neck abscess, pyothorax and empyema, pneumonia, urinary tract infection, intra-abdominal abscess, soft tissue infection, septic arthritis and osteomyelitis, and surgical-site infection. Ultrasound was useful for evaluating the extent and location of inflammation and abscess and for decision-making concerning surgical intervention. CONCLUSION Knowledge of these sonographic findings is important for sonographers during examinations and for physicians when determining the treatment plan and period of antibiotic therapy for infected lesions.

Abstract
Background Cervicofacial space infections are potentially life-threatening, which require accurate diagnosis, early incision, and adequate drainage. The utilization of computed tomography (CT) in cervicofacial space infections has significantly increased for its advantages in the evaluation of abscesses, its availability, and low cost. However, the clinical value of preoperative CT imaging in cervicofacial space infections remains controversial for its poor specificity, radiation exposure, potential complications, and extra cost. We, therefore, investigated whether CT examination should be used as a routine examination in the treatment of patients with cervicofacial space infections. Methods A retrospective study of all patients affected by cervicofacial space infections that received incision and drainage surgery from Jan 2016 to Dec 2020 was performed at West China Hospital of Stomatology at Sichuan University. Patients were divided into two groups: the group with preoperative CT and without preoperative CT. Outcomes, including reoperation rate, missed diagnosis rate, days of symptom relief, length of stay, duration of surgery, and total cost of hospitalization, were analyzed. Results Out of n = 153 patients, 108 patients underwent surgery with preoperative CT and 45 patients without preoperative CT. The reoperation rate in the preoperative CT group (6/108, 5.6%) was significantly lower (P = 0.00) than that in the group without preoperative CT (10/45, 22.2%). Significant reduction of missed diagnosis rate (P = 0.00), days of symptom relief (P = 0.01), length of stay(P = 0.03), and duration of surgery (P = 0.01) were detected in the preoperative CT group. The results demonstrated that the utilization of preoperative CT can reduce the missed diagnosis rate and repeated surgery complications. Conclusions We recommend preoperative CT as a routine examination in cervicofacial space infections.

Abstract
A 5-year-old male neutered mixed breed dog and an 8-year-old female spayed golden retriever presented for cervical swelling which was later diagnosed as abscessation of the retropharyngeal lymph node with a malignant round cell tumor and carcinoma with multifocal squamous differentiation, respectively. In veterinary medicine, there is limited published information regarding abscessation of lymph nodes secondary to a neoplastic process. While more common in humans, there are only limited case reports available. Advanced imaging (computed tomography), cytology, surgical excision, and histopathology lead to the final diagnosis. Both dogs underwent surgical extirpation of the lymph nodes and adjuvant chemotherapy protocols. Six weeks postsurgical excision, dog one was euthanized due to quality-of-life concerns. The second dog successfully completed 18 treatments of radiation therapy and was still alive at 388 days postsurgical excision. At the time of manuscript submission, the second dog was doing well clinically.

Abstract
OBJECTIVES/HYPOTHESIS To examine the pathogenic bacterial spectra and prognosis of deep neck infection (DNI) in end-stage renal disease (ESRD) patients. STUDY DESIGN Retrospective study. METHODS Patients diagnosed with DNI between 2004 and 2015 in Chang Gung Memorial Hospital were enrolled and divided into three groups, namely ESRD-DNI, chronic kidney disease (CKD)-DNI, and non-CKD-DNI. Differences in pathogenic bacteria, treatment, and prognosis were compared across the three groups. RESULTS The bacterial spectra differed among the three groups. The main three facultative anaerobic or aerobic bacteria causing ESRD-DNIs were methicillin-resistant Staphylococcus aureus (MRSA; 25.4%), methicillin-susceptible S. aureus (MSSA; 14.1%), and Klebsiella pneumoniae (KP; 12.7%). For CKD-DNIs, they were KP (23.5%), Viridans streptococci (VS; 23.5%), and MSSA (14.7%). For non-CKD-DNIs, they were VS (31.7%), KP (17.2%), and coagulase-negative staphylococci (8.0%). Compared with the other groups, the ESRD-DNI group had higher white blood cell and C-reactive protein levels, longer hospital stays, more frequent admissions to the intensive care unit, more mediastinal complications, and a significantly higher mortality rate. CONCLUSIONS The ESRD-DNI group exhibited more severe disease activity and higher mortality compared with those of the CKD-DNI and non-CKD-DNI groups. MRSA was the leading pathogen for patients with ESRD-DNI. Physicians must implement strategies for the early detection of MRSA to accurately prescribe antibiotics and prevent nosocomial transmission.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has generated many challenges for physicians, including multiple long-term effects that are still being studied. We report a CASE of patient who developed a retropharyngeal abscess post-COVID19 infection. We report a CASE of a female who was diagnosed with COVID19 pneumonia and hospitalized for a week at an outside institute. Approximately 3 weeks post discharge she developed neck pain, dysphagia, voice change and odynophagia for which she went to an outside emergency department. A soft tissue neck CT was performed and was concerning for retropharyngeal abscess. The patient was then transferred to our institution. On arrival, a CT scan of the neck and nasopharyngoscopy were performed and biopsies of the epiglottis and right inferior tonsillar pole were taken. Biopsies of the epiglottis and tonsil showed acute inflammation, spongiosis, edema and marked dilation of the lymphatics. Her clinical course was complicated by persistent infection requiring multiple washouts, hyperglycemia, tube feed intolerance, dysphagia and deconditioning. A multi-disciplinary approach was instituted for appropriate management. This case report highlights the necessity for close follow up after recovery from COVID-19 infection, particularly in patients with multiple comorbidities.

Abstract
The aim of this study was to comprehensively review our experience with odontogenic infections in the head and neck region requiring treatment at a national referral center. We retrospectively reviewed 85 patients treated at the Chair and Clinic of Maxillofacial Surgery of the University Hospital in Wrocław between January 2018 and June 2019. We excluded patients with nonondontogenic infections or other than purulent clinical forms of dentivitis in the head and neck region. Several demographic, clinicopathological, and treatment variables were assessed. The majority of patients were men who were referred for inpatient treatment by a dentist or family doctor, presented to the Hospital Emergency Ward (SOR) by themselves, or transported to the SOR by paramedics SOR from their home or another hospital. All patients were treated in accordance with the current guidelines for head and neck region odontogenic infections. An incision was made and the abscess was drained. The odontogenic cause was removed followed by the collection of tissue for microbiological examination. The course of infection was monitored by means of laboratory parameters such as leukocyte counts and c-reactive protein levels. Odontogenic infections in the head and neck region are a persistent and common problem. Rapid, accurate diagnosis and treatment minimizes the risk of life-threatening complications, shortens the hospitalization period, and lowers treatment costs.

Abstract
Perforation of the larynx is very rare but may result in severe airway complications that include pneumothorax, pneumonia, mediastinitis, and retropharyngeal abscess. If conservative treatment fails, aggressive treatments including reconstructive surgery with pedicle flap are considered. Negative pressure wound therapy has been used for large skin defects, necrotizing fasciitis, pharyngocutaneous fistula, stoma dehiscence, osteoradionecrosis of the mandible, chyle fistula, flap failure, and lymphangioma in the field of head and neck surgery. We report a case of false vocal cord perforation with abscess successfully treated by negative pressure wound therapy after abscess treatment. The result suggests that negative pressure wound therapy can be an alternative or adjunctive approach for larynx perforation when the perforation is difficult to close after conservative therapy.

Abstract
Purpose Otorhinolaryngological abnormalities are common complications of chronic kidney disease (CKD) and its treatment. The main aim of this study was to provide a brief and precise review of the current knowledge regarding CKD and its treatment-related influence on head and neck organs. Methods The Medline and Web of Science databases were searched using the terms “chronic kidney disease”, “kidney transplantation”, “immunosuppression”, “dialysis” in conjunction with “otorhinolaryngological manifestation”. Articles that did not address the topics, low-quality studies, case reports, and studies based on nonsignificant cohorts were excluded, and the full text of remaining high-quality, novel articles were examined and elaborated on. Results Patients with CKD are prone to develop sensorineural hearing loss, tinnitus, recurrent epistaxis, opportunistic infections including oropharyngeal candidiasis or rhino-cerebral mucormycosis, taste and smell changes, phonatory and vestibular dysfunctions, deep neck infections, mucosal abnormalities, gingival hyperplasia, halitosis or xerostomia. Immunosuppressive therapy after kidney transplantation increases the risk of carcinogenesis, both related and not-related to latent viral infection. The most commonly viral-related neoplasms observed in these patients are oral and oropharyngeal cancers, whereas the majority of not-related to viral infection tumors constitute lip and thyroid cancers. CKD-related otorhinolaryngological dysfunctions are often permanent, difficult to control, have a significant negative influence on patient’s quality of life, and can be life threatening. Conclusion Patients with CKD suffer from a number of otorhinolaryngological CKD-induced complications. The relationship between several otorhinolaryngological complications and CKD was widely explained, whereas the correlation between the rest of them and CKD remains unclear. Further studies on this subject are necessary.

Microorganisms involved in deep neck infection (DNIs) in Greece: detection, identification and susceptibility to antimicrobials. BMC Infect Dis 2019; 19:850. [PMID: 31615449 PMCID: PMC6794762 DOI: 10.1186/s12879-019-4476-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Accepted: 09/13/2019] [Indexed: 11/10/2022] Open
Abstract
Background To determine, from October 2010 to October 2018, the epidemiology of Deep Neck Infections (DNIs), regarding the detection, the identification and the susceptibility to antimicrobials of causative microorganisms, in Thessaly-Central Greece. Methods An analysis of data from a prospective database was conducted on 610 consecutive patients with DNIs treated in the Otolaryngology / Head & Neck Surgery Department of University Hospital of Larissa. Demographics, clinical features and microbiological data were analyzed. Results Among the 610 patients (1,9/1 male to female ratio, mean age: 39,24 ± 17,25) with DNIs, 579 had a single space (94,9%), while the remaining 31 had a multi-space (5,1%) DNI. The most common areas affected were the peritonsillar space (84,6%) followed by the submandibular space (6,5%). Clinical samples were obtained from 462 patients, and were tested by culture and by the application of 16S rRNA PCR. Two hundred fifty-five samples (55,2%) gave positive cultures, in which Streptococcus pyogenes and Staphylococcus aureus were predominant. The application of the 16S rRNA PCR revealed that 183 samples (39,6%) were positive for bacterial DNA; 22 of them, culture negative, were found to be positive for anaerobic (Fusobacterium necrophorum, Actinomyces israellii etc) and for fastidious microorganisms (Brucella mellitensis, Mycobacterium avium). Conclusion DNIs represent a medical and surgical emergency and evidence-guided empirical treatment with intravenous infusion of antibiotics at the time of diagnosis is mandatory, highlighting the importance of epidemiological studies regarding the causative microorganisms. Although, in our study, the predominant pathogens were S. pyogenes and S. aureus, the combination of culture and molecular assay revealed that anaerobic bacteria play also a significant role in the pathogenesis of DNIs. Based on the local epidemiology, we propose as empirical therapy the intravenous use of a beta-lactam /beta-lactamase inhibitor; metronidazole or clindamycin can be added only in specific cases such as in immunocompromised patients.

Abstract
Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) is a novel technique with better cosmetic results. However, extraction of a large malignant thyroid nodule from the central incision of TOETVA necessitates breaking it into pieces to avoid mental nerve injury, a situation that may violate a proper oncological surgery. In this study, we sought the appropriate nodular diameter in thyroid cancer to be removed in an intact status through the central incision of the TOETVA technique. A total of 27 cases of thyroid nodules were operated using the TOETVA technique from Aug 2016 to July 2017. Excluding 10 benign goiters, the specimens of 17 thyroid cancer cases were divided into intact (group T, n=7) and fragmented (group F, n=10), with a median nodular diameter of 18.35 and 30.30 mm, respectively. Receiver operating characteristic (ROC) curve analysis revealed that the safest nodular diameter is 20 mm, with 100% sensitivity and 87.5% specificity.

Abstract
Deep neck spaces are still common in developing countries like India, even though its less prevalent in developed nations. It can lead to serious complications like jugular vein thrombosis and dissemination of infection if not diagnosed early and intervened. This is a retrospective chart review of 52 patients from 2014 to 2017 in a tertiary care hospital. Only patients with infection deeper to the superficial fascia of neck were included. Submandibular space infection was the most common and precipitating factor being dental infection. Most common comorbid condition was diabetes mellitus. Klebsiella pneumoniae was the most common isolated organism and few patients had mixed culture with anaerobes. Injectable cephalosporin with metronidazole was the most effective antibiotic combination against such infections. Low threshold for early surgical intervention reduce hospital stay and enable quick recovery of patients. Usage of over the counter antibiotics masks the conditions and complicate diagnosis and treatment of this condition.

Abstract
OBJECTIVES This study sought to investigate the impact of involvement of the infrahyoid neck space on the management of non-odontogenic DNI. METHOD Eighty-one patients treated for non-odontogenic DNI over 5 years were retrospectively recruited into this study. Demographics, etiology, radiology results, treatments, duration/cost of hospital stay, and complications were recorded. Differences between DNIs with and without infrahyoid involvement, as defined based on an anatomical chart, were analyzed. RESULTS Sixty-two male and 19 female patients with a median age of 46.22 years were included. Fifteen patients had cellulitis, and 66 patients had abscesses. Streptococcus was the most commonly observed bacterium. Compared with DNIs only in suprahyoid spaces (n = 60, 74.07%), DNIs with infrahyoid space involvement (n = 21, 25.93%) were associated with higher incidences of the involvement of ≥3 spaces (85.71%, P = 0.000), mediastinitis (38.10%, P = 0.000), tracheostomy (28.57%, P = 0.008), surgery using a transcervical approach (66.67%, P = 0.000), and intensive care unit therapy (19.05%, P = 0.004), as well as longer hospital stays (16 days, P = 0.000) and higher costs ($2872, P = 0.000). CONCLUSION Infrahyoid involvement should be regarded as a high-risk factor in the management of deep neck infection (DNI). A relatively aggressive plan that includes transcervical surgery and tracheostomy should be considered at earlier stages for DNI with infrahyoid involvement.

Abstract
A 62-year-old man with a background of type 2 diabetes mellitus presented to the emergency department (ED) with a 5-day history of dental pain, progressive right facial swelling, trismus, dysphagia and voice changes. The oropharynx could not be directly examined completely due to trismus. The patient had a National Early Warning Score of 0 and so was triaged into the ‘minors’ section of ED. Following assessment by the on-call oral and maxillofacial surgeon, an urgent contrast-enhanced CT demonstrated a large parapharyngeal collection, which required urgent anaesthetic and surgical intervention. The patient developed pulmonary complications postoperatively, but eventually made a full recovery.

Abstract
Introduction Deep neck infections are defined as suppurative infectious processes of deep visceral spaces of the neck. Objective The aim of this study is to review different factors that may influence peritonsillar and deep neck infections and may play a role as bad prognosis predictors. Methods We present a retrospective study of 330 patients with deep neck infections and peritonsillar infections who were admitted between January 2005 and December 2015 in a tertiary referral hospital. Statistical analysis of comorbidities, diagnostic and therapeutic aspects was performed with Excel and SPSS. Results There has been an increase in incidence of peritonsilar and deep neck infections. Systemic comorbidities such as diabetes or hepatopathy are bad prognosis factors. The most common pathogen was S. viridans (32.1% of positive cultures). 100% of the patients received antibiotics and corticosteroids, 74.24% needed surgical treatment. The most common complications were mediastinitis (1.2%) and airway obstruction (0.9%). Conclusion Systemic comorbidities are bad prognosis predictors. Nowadays mortality has decreased thanks to multidisciplinary attention and improvements in diagnosis and treatment.

Abstract
BACKGROUND Deep neck infections are important otolaryngologic emergencies due to serious complications and the risk of airway compromise, which can lead to mortality. Although the most common causes among pediatric patients are tonsillitis and pharyngeal infections, odontogenic infections are an important cause in adults. CASE REPORT We present three patients with multiple deep neck space abscess formation due to odontogenic infection. Two of them required tracheotomy due to airway compromise, and one had mediastinitis. CONCLUSION An underestimated tooth infection can cause hazardous complications such as mediastinitis and respiratory distress requiring tracheotomy.

Abstract
Bezold's and Citelli's abscesses are rare complications of otitis media. We present a case of a 44-year-old Eastern European man, with a history of recurrent otitis media, who was admitted to hospital with mastoiditis and initially treated with antibiotics. Despite clinical improvement, a CT scan showed mastoiditis with Bezold's and Citelli's abscesses. The patient underwent a myringotomy and grommet insertion, in addition to a cortical mastoidectomy and curettage of the neck abscesses. After a good recovery, he was discharged home. However, likely due to the language barrier, he did not complete a course of antibiotics as prescribed, and the abscess re-collected, necessitating a re-admission and re-operation. This report illustrates the importance of considering rare features of a common disease in the differential, and of communication in ensuring compliance.
