Parapharyngeal abscess
Parapharyngeal Abscess
Parapharyngeal abscess (pronounced: para-fair-in-gee-al abscess) is a deep neck infection that is potentially life-threatening due to its proximity to major vascular and neural structures.
Etymology
The term "parapharyngeal" is derived from the Greek words "para" meaning beside, and "pharynx" meaning throat, referring to the area of the neck adjacent to the pharynx. "Abscess" is derived from the Latin word "abscessus" meaning a going away, referring to the pus that has 'gone away' from the body tissues.
Definition
A parapharyngeal abscess is a deep neck infection that forms in the potential space in the neck, known as the parapharyngeal space. This space is located on either side of the upper part of the throat and is bounded by the muscles and fascia of the neck.
Symptoms
Symptoms of a parapharyngeal abscess can include severe sore throat, difficulty swallowing (dysphagia), neck pain, neck swelling, fever, and a change in voice (dysphonia).
Causes
Parapharyngeal abscesses are usually caused by a bacterial infection that has spread from a primary site of infection, such as the throat or mouth. Common bacteria that cause these abscesses include Streptococcus and Staphylococcus species, and anaerobic bacteria.
Treatment
Treatment of a parapharyngeal abscess typically involves antibiotics to treat the infection and surgical drainage of the abscess. In some cases, the abscess may need to be drained more than once.
