[Retropharyngeal abscess: case study of 5 cases and literature review].

The purpose of this study was to perform correlation of 5 cases and literature review. The study involved both children and adults. The major cause of retropharyngeal abscess was fish bone foreign body. Dysphagia associated with pain, fever and torticollis were the most common symptoms. Retropharyngeal abscess mainly occurred in the oropharyngeal and hypopharyngeal regions. Imaging tests, in particular CT scan, allowed for accurate information in 3 cases. Aerodigestive tract obstruction was found in most of our patients. Only 4 patients underwent incision and drainage. All patients received medical treatment. A 2-year-old died 5 days after surgery due to septic shock. This study highlights the rarity of this condition in our context as well as the importance of early diagnosis and treatment to prevent life-threatening complications.
