Deep neck abscess in neonatal period: case report and review of literature

Paediatric Deep Neck Infection—The Risk of Needing Intensive Care

Deep neck infections are potentially dangerous complications of upper respiratory tract or odontogenic infections. The pathophysiology, clinical presentation, and potential spreading depend on the complex anatomy of the neck fascia. These infections can lead to severe pathological conditions, such as mediastinitis, sepsis, and especially airway impairment with difficult management. Because of the risk of life-threatening emergency situations and the possible impacts on the overall health status of affected children, their early recognition is of utmost importance. Torticollis, drooling, and stridor are the most common signs of advancing disease. Children presenting with these symptoms should be admitted to the paediatric intensive care unit for vital function monitoring, where the airway could be readily secured if function is compromised.

Diagnosis and treatment of deep neck abscess due to congenital piriform sinus fistula in children

INTRODUCTION

Congenital piriform sinus fistula is a relatively rare type of disease in clinical practice, most occurring during childhood, but doctors have insufficient knowledge regarding this disease, easily misdiagnosing it.

OBJECTIVES

This study aimed to identify the characteristics of deep neck abscess due to congenital piriform sinus fistula in children.

METHODS

We performed a retrospective study of 21 cases from January 2016 to August 2018 in our hospital. The onset age, clinical characteristics, auxiliary examination and clinical treatment of the patients was summarized to analyze the diagnosis, treatment characteristics and prognosis.

RESULTS

Children from 11 days to 12 years-old were enrolled, with an average age of 3.5 years. Twenty patients had left congenital piriform sinus fistula and 1 had right congenital piriform sinus fistula. Cervical enhanced computed tomography imaging showed gas-liquid equilibrium or air-shadow in the abscesses in 18 cases, and neck ultrasound demonstrated gas echo in the thyroid region in 10 cases. All patients underwent low temperature plasma to seal the internal fistula and returned to the hospital for electronic laryngoscope and neck ultrasound examination at 3 months, 6 months and 1year after the surgery. No recurrence occurred in any patient.

CONCLUSION

Congenital piriform sinus fistula is an important cause of deep neck abscess in children. The presence of purulent gas-liquid equilibrium or air shadow in cervical-enhanced computed tomography or ultrasound suggests a high possibility of the presence of an internal fistula, and endoscopic low temperature ablation can be done at the same time as the diagnostic endoscopy.

Clinical characteristics for conservative therapy of pediatric parapharyngeal abscesses

Introduction

The role of surgical drainage versus conservative therapy in treating patients with parapharyngeal abscesses is still a theme of debate.

Objectives

This study aimed to investigate the characteristics associated with good outcomes in pediatric patients with parapharyngeal abscesses treated with conservative therapy.

Methods

This retrospective chart review was performed on children aged 0.3–14 years with the diagnosis of parapharyngeal abscesses confirmed by computed tomography from January 2013 to March 2018. Patients with a severe upper airway obstruction required early intervention, while those in a stable condition initially received conservative therapy with antibiotics. If the patients appeared unlikely to recover, additional surgical drainage was provided. Multivariate logistic regression models were constructed to investigate the clinical characteristics associated with a good response to conservative therapy. A receiver operating characteristic curve was used to identify the age and abscess size cutoff for predicting a successful response.

Results

A total of 48 children were included in the study. Patient age, antecedent illness, and abscess size were significantly associated with a response to therapy (Odds Ratio = 1.326, 2.314 and 1.235, respectively). The age cutoff associated with the conservative therapy was 4.2 years (76.9% sensitivity, 68.2% specificity), and the abscess size cutoff associated with the conservative therapy was 23 mm (84.6% sensitivity, 77.3% specificity).

Conclusion

The findings suggested that younger age, smaller abscess size, and less frequent antecedent illnesses, such as upper respiratory tract infection and lymphadenitis, could predict a successful response to conservative therapy in pediatric patients with parapharyngeal abscesses.

Geographic health disparities in the Los Angeles pediatric neck abscess population

OBJECTIVE

To assess geographical sociodemographic differences in neck abscesses that require surgical drainage in Los Angeles.

STUDY DESIGN

retrospective review.

METHODS

We reviewed the medical records of 119 consecutive pediatric patients at Children's Hospital Los Angeles (CHLA) from 2014 to 2017 with a diagnosis of a neck abscess requiring incision and drainage. Sociodemographic information including zip code of residence was extracted and analyzed with Chi-square, Fisher's exact test, and multivariate logistic regression.

RESULTS

The average age of patients with a neck abscess in this study was 3.4 years old, 53.8% were female, 54.6% were Hispanic, and 82.5% had public health insurance. 79% of patients had an abscess located in the superficial neck, and 10.1% had an abscess located in the retropharyngeal space. There were no significant differences in gender, race, type of health insurance, or income between patients that lived within 10 miles of CHLA versus those that lived farther than 10 miles. On multivariate analysis, zip codes with a high volume of neck abscesses were more likely to be lower income neighborhoods. Gender, race, type of health insurance, and distance from CHLA were not associated with zip codes with a high volume of neck abscesses.

CONCLUSION

Geographic areas in the greater Los Angeles community with a high volume of neck abscesses requiring incision and drainage at our institution were associated with lower income neighborhoods.
