Final answer:
Retropharyngeal abscess is an infection that forms an abscess behind the throat. It is commonly caused by Group A Streptococcus and anaerobic bacteria. Treatment involves incision and drainage, along with antibiotics.
Step-by-step explanation:
Retropharyngeal abscess is a condition characterized by the formation of an abscess in the retropharyngeal space, which is located behind the throat. The abscess is usually caused by an infection, commonly by Group A Streptococcus (GAS) and anaerobic bacteria. The recommended treatment for retropharyngeal abscess includes incision and drainage (I&D) followed by culture and sensitivity testing (C&S). Third generation cephalosporins, along with ampicillin or clindamycin, are commonly used antibiotics for this condition. Complications of retropharyngeal abscess may include the spread of infection to the mediastinum, which can lead to mediastinitis.
