Objective
The purpose of this study was to evaluate the diagnosis circumstances, predisposing factors, investigations, and therapeutic management of retropharyngeal and parapharyngeal abscesses.
Methods
A retrospective chart review of patients diagnosed with retropharyngeal or parapharyngeal abscess from 2001 to 2021 was performed. Epidemiological characteristics, clinical signs, investigations, medical treatment, and surgical interventions were analyzed for each patient.
Results
A total of 30 patients with retropharyngeal or parapharyngeal abscess were identified. Computed tomography was performed in all cases, and magnetic resonance imaging was performed in three cases. Twelve patients had a “pure” retropharyngeal abscess, nine patients had a prestyloid abscess, one patient had a prestyloid abscess associated with a peritonsillar abscess, three patients had a retrostyloid abscess, and five patients had a prestyloid abscess associated with a retropharyngeal abscess or a retrostyloid abscess. The median long axis of the abscess was 42 cm. All patients received intravenous antibiotics for a median period of 8 days [4–30]. Seventeen patients required surgical trans-cervical drainage. Other patients underwent transoral or transnasal drainage. The pus culture revealed no growth in six cases, streptococcus (four cases), methicillin-sensitive Staphylococcus aureus (two cases), Klebsiella (two cases), Enterobacter (one case), Fungi (two cases), and Mycobacterium tuberculosis (a twelve-year-old boy). It was not documented in twelve cases. Histological examination revealed caseofollicular tuberculosis in a 53-year-old man. In 25 patients, no adverse events were observed during follow-up. Five patients had an unfavorable outcome.
Conclusion
We have found an increase in the incidence of these infections in recent years. Computed tomography is the best imaging examination for the diagnosis and follow-up of retropharyngeal and parapharyngeal abscess. Early drainage and antimicrobial therapy are essential for rapid recovery and prevention of complications of these abscesses.
