The assessment and management of deep neck space infections in adults: A systematic review and qualitative evidence synthesis

OBJECTIVES

To summarise current practices in the diagnosis and management of deep neck space infections (DNSIs). To inform future studies in developing a framework in the management of DNSIs.

DESIGN

This review was registered on PROSPERO (CRD42021226449) and reported in line with PRISMA guidelines. All studies from 2000 that reported the investigation or management of DNSI were included. The search was limited to English language only. Databases searched included AMED, Embase, Medline and HMIC. Quantitative analysis was undertaken with descriptive statistics and frequency synthesis with two independent reviewers. A qualitative narrative synthesis was conducted using a thematic analysis approach.

SETTING

Secondary or tertiary care centres that undertook management of DNSIs.

PARTICIPANTS

All adult patients with a DNSI.

MAIN OUTCOME MEASURES

The role of imaging, radiologically guided aspiration and surgical drainage in DNSIs.

RESULTS

Sixty studies were reviewed. Thirty-one studies reported on imaging modality, 51 studies reported treatment modality. Aside from a single randomised controlled trial, all other studies were observational (n = 25) or case series (n = 36). Computer tomography (CT) was used to diagnose DNSI in 78% of patients. The mean percentage of management with open surgical drainage was 81% and 29.4% for radiologically guided aspiration, respectively. Qualitative analysis identified seven major themes on DNSI.

CONCLUSIONS

There are limited methodologically rigorous studies investigating DNSIs. CT imaging was the most used imaging modality. Surgical drainage was commonest treatment choice. Areas of further research on epidemiology, reporting guidelines and management are required.

Multisystem inflammatory syndrome in children associated with COVID-19 presenting as cervical inflammation

AIM

The major clinical manifestations multisystem inflammatory syndrome in children (MIS-C) are fever, gastrointestinal and cardiac. The aim of this study was to describe MIS-C in a series of patients who presented primarily with cervical manifestations.

METHODS

We retrospectively reviewed medical records of all patients who met the Centers for Disease Control and Prevention and World Health Organization MIS-C diagnostic criteria treated at Hadassah-Hebrew University Medical Center between April 2020 and September 2021.

RESULTS

Of 37 children diagnosed with MIS-C (median age: 10.2 years, range 1.5-18 years, 20 male) five, 13.5% (median age: 14.4 years, range 9.2-17.5 years) presented with cervical symptoms mimicking neck infections. One was hospitalised with a working diagnosis of retropharyngeal abscess, and four with acute cervical lymphadenitis that did not respond to early antibiotic treatment. All developed full MIS-C phenotype.

CONCLUSION

MIS-C may present as cervical inflammation. An ill-appearing child with symptoms and/or signs of cervical inflammation should be evaluated for clinical and laboratory features of MIS-C, thereby facilitating prompt treatment of this potentially fatal disorder.

Fourth Branchial Anomalies: Diagnosis, Treatment, and Long-Term Outcome

Introduction: Fourth branchial anomalies, the rarest among anomalies of the branchial apparatus, often present diagnostic and therapeutic challenges. We evaluated the clinical presentation and radiographic features, the treatment and the long-term outcome of patients in this setting.

Patients and Methods: Of 12 patients treated in the University Hospitals Leuven from 2004 until 2020, 12 variables were collected: date of birth, gender, age of onset of the symptoms, age at final diagnosis, presentation, laterality, previous procedures, diagnostic tools, treatment (open neck surgery, endoscopic laser excision, or combination), complications, recurrence, and period of follow-up. Descriptive statistics were calculated and results were compared to the existing literature.

Results: The most common clinical manifestations were recurrent neck infections with and without abcedation. Definitive diagnosis using direct laryngoscopy, visualizing the internal sinus opening, was possible in all patients. A CT study revealed the typical features of fourth branchial anomalies in seven patients out of nine, an ultrasound study in five out of nine patients. All patients underwent open neck surgery. If this was insufficient, secondary endoscopic laser resection of the ostium at the apex of the piriform sinus was performed (n = 4). In eight patients a thyroid lobectomy was needed for safe complete resection. Postoperative complications were minimal and at long-term, none of the patients showed further recurrence. Average time of follow-up was 8.6 years.

Conclusions: Direct laryngoscopy and CT are the most accurate diagnostic tools. Our recommended treatment schedule consists of complete excision of the sinus tract by open neck surgery as the primary treatment because this ensures the best results. In case of recurrence afterwards, endoscopic laser resection of the pharyngeal ostium solved the problem.

Airway Management with Dexmedetomidine and High-Flow Nasal Cannula in a Patient with Deep Neck Infection

Retropharyngeal deep neck infection sometimes necessitates securing of the airway and surgery for drainage. Airway management in patients with deep neck infection is challenging for anesthesiologists. A 56-year-old woman diagnosed with deep neck infection was admitted for incision and drainage. In the first operation for incision and drainage, indirect videolaryngoscope was utilized to confirm the airway before tracheal intubation, and the patient was intubated successfully. In the second operation for wound closure, dexmedetomidine administration and high-flow nasal cannulation were used during monitored anesthesia care throughout a subsequent procedure. The outcome in the present case suggests that indirect videolaryngoscope, dexmedetomidine, and high-flow nasal cannula can facilitate effective management during surgery in patients with retropharyngeal deep neck space infection.

Paratracheal abscess after traumatic tracheal intubation

Major complications of laryngoscopy and tracheal intubation are rare. However, mucosal trauma during airway management can lead to the introduction of oropharyngeal bacterial flora into the deep neck spaces, with the potential for fatal complications. This report describes the development of a paratracheal abscess in a healthy 62-year-old man following an outpatient herniorrhaphy. The patient was treated with intravenous antibiotics and underwent ultrasound-guided needle aspiration of the abscess. He was later re-admitted to the hospital with re-accumulation of the abscess, which was successfully treated by open surgical drainage. Though deep neck space infection following laryngoscopy is more common in patients with significant comorbidities and when tracheal intubation has been difficult, this case highlights the need for careful airway management in all patients.

Huntington's disease with severe neck infection

OBJECTIVE

To present a case of Huntington's disease (HD) with severe neck infection.

BACKGROUND

Huntington's disease (HD) is a progressive neurodegenerative genetic disorder and is often accompanied by dysphagia.

MATERIALS AND METHODS

The patient was a 64-year-old man with HD. The severe neck infection was considered as one of the symptoms of HD.

CONCLUSION

Clinicians should remember that patients with HD are apt to delay dental consultation, resulting in serious oral infections.
