Parapharyngeal abscess in an infant is a very rare condition. We present the case of a 4-month-old girl with large masses on the neck's left side. Computed tomography showed an extensive parapharyngeal abscess. Left tonsillectomy was performed under general anesthesia from a transoral approach, followed by an incision and evacuation of the abscess from the parapharyngeal space. Microbiological analysis identified a massive occurrence of Streptococcus intermedius ., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: The aim of our study was to describe clinical presentations, bacteriological results, and therapeutic management in a pediatric population presenting with acute pharyngeal suppuration. A further aim was to identify clinical, bacteriological, and radiological predictors of success associated with exclusive medical treatment., Method: A retrospective study was carried out including patients under 18 years of age hospitalized between January 1, 2015 and December 31, 2017 in our center for acute pharyngeal suppuration. We identified three groups of patients: group A, treated with exclusive intravenous antibiotics; group B, surgically treated after 48 h of appropriate antibiotic therapy, due to persistent fever and/or clinical worsening and/or persistence of a collection on follow-up imaging; group C, surgically treated as first-line therapy in association with intravenous antibiotics. A total of 83 patients were included: 36 in group A, 12 in group B, and 35 in group C. These three groups were compared for several variables: age of the patients, polynuclear neutrophil counts, diameter of the collections (the largest diameter found on imaging), duration of antibiotic therapy, delay before return to apyrexia, and hospitalization duration., Results: A neck mass and torticollis were present, respectively, in 48.8 and 47.6% of cases. No breathing difficulties were reported. Streptococcus pyogenes was the most frequently identified microorganism. The average diameter of the collections from patients treated surgically as first-line therapy (group C) was significantly larger than that of the patients treated with antibiotics (group A) (27.89 mm vs. 18.73 mm, respectively, p = 0.0006). All the patients who required surgery despite 48 h of appropriate antibiotic therapy (group B) had collections with diameters greater than or equal to 15 mm. There was no significant difference between the groups concerning hospitalization duration., Conclusion: Exclusive medical treatment is associated with a high cure rate, mainly for collections with small diameter. We recommend special attention to patients treated with first-line exclusive intravenous antibiotic therapy and with a collection diameter greater than or equal to 15 mm., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 French Society of Pediatrics.

We aimed to describe the microbiology of parapharyngeal abscess (PPA) and point out the likely pathogens using the following principles to suggest pathogenic significance: (1) frequent recovery, (2) abundant growth, (3) growth in relative abundance to other microorganisms, (4) percentage of the isolates recovered in both absolute and relative abundance, (5) more frequent recovery in PPA pus compared with tonsillar surface and tissue. Comprehensive bacterial cultures were performed on specimens obtained from adult patients (n = 60) with surgically verified PPA, who were prospectively enrolled at five Danish ear-nose-throat departments. The prevalent isolates (in PPA pus) were unspecified anaerobes (73%), non-hemolytic streptococci (67%), Streptococcus anginosus group (SAG) (40%), Corynebacterium spp. (25%), Neisseria spp. (23%), Fusobacterium spp. (22%), Fusobacterium necrophorum (17%), Prevotella spp. (12%), and Streptococcus pyogenes (10%). The bacteria most frequently isolated in heavy (maximum) growth were unspecified anaerobes (60%), SAG (40%), F. necrophorum (23%), and Prevotella spp. (17%). The predominant microorganisms (those found in highest relative abundance) were unspecified anaerobes (53%), SAG (28%), non-hemolytic streptococci (25%), F. necrophorum (15%), S. pyogenes (10%), and Prevotella spp. (10%). Four potential pathogens were found in both heavy growth and highest relative abundance in at least 50% of cases: F. necrophorum, Prevotella spp., SAG, and S. pyogenes. SAG, Prevotella spp., F. necrophorum, S. pyogenes, and Bacteroides spp. were recovered with the same or higher frequency from PPA pus compared with tonsillar tissue and surface. Our findings suggest that SAG, F. necrophorum, Prevotella, and S. pyogenes are significant pathogens in PPA development.

Parapharyngeal infection is the most common deep neck space infection in children and, in rare instances, can result in bony destruction of the cervical spine. We report one such case that required occipital to cervical fusion and halo-vest fixation. We also review the literature and discuss the etiology, diagnosis, and treatment options for managing pediatric cervical bony destruction secondary to infection.
