Parapharyngeal Abscess

Parapharyngeal abscess is a serious medical condition that necessitates prompt diagnosis and treatment. In this article, we will discuss the  causes, symptoms, and diagnostic methods used to diagnose this condition.

What is a Parapharyngeal Abscess?

A parapharyngeal abscess is a painful collection of pus found within the deep neck space known as the parapharyngeal space. It often arises as a complication of upper respiratory infections, such as tonsillitis or pharyngitis.

Causes of Parapharyngeal Abscess:

  1. Infections: Parapharyngeal abscesses are typically triggered by bacterial infections, with common culprit being Streptococcus.
  2. Upper Respiratory Infections: Infections affecting the throat and tonsils can progress to a parapharyngeal abscess if left untreated.
  3. Dental Issues: Dental infections or abscesses can spread to the deep neck space, potentially leading to the development of a parapharyngeal abscess.

Symptoms of Parapharyngeal Abscess:

  1. Severe Throat Pain: Patients frequently endure intense throat pain, which can make swallowing difficult.
  2. Fever and Chills: A high fever and chills are common symptoms, often indicating an underlying infection.
  3. Swelling of the Neck: Swelling in the neck area, typically on one side, may be observable and is accompanied by tenderness.
  4. Difficulty Swallowing: The abscess can obstruct the throat, leading to difficulties with swallowing.

Diagnostic Imaging for Parapharyngeal Abscess:

  1. Computed Tomography (CT) Scan: CT scans serve as the primary diagnostic tool for pinpointing parapharyngeal abscesses. They supply detailed cross-sectional images, allowing for precise assessment of the abscess’s size and location.
  2. Magnetic Resonance Imaging (MRI): MRI scans can also be utilized to visualize parapharyngeal abscesses, offering excellent soft tissue contrast for assessing the extent of the infection.
  3. Ultrasonography: While less common, ultrasound may be employed to assess superficial neck swellings, although it may not offer the same level of detail as CT or MRI scans.
  4. X-ray: Although not the first choice, X-rays can provide a basic view of the neck area, offering an initial step in the diagnostic process.

Diagnosing Parapharyngeal Abscess:

A healthcare professional will conduct a thorough examination and consider the patient’s symptoms. If a parapharyngeal abscess is suspected, diagnostic imaging, such as a CT scan or MRI, will be requested to confirm the diagnosis. Once the abscess is identified, prompt treatment can be started to prevent potential complications.


This typically involves a combination of medical and surgical interventions. Antibiotics are administered to combat the underlying bacterial infection, helping to reduce inflammation and prevent further complications.

Drainage of the abscess is an important step, often achieved through a minor surgical procedure. This procedure involves making an incision in the abscess to release the trapped pus, relieving pressure and promoting healing. In some cases, a tube or drain may be left in place to facilitate ongoing drainage.

Pain management and supportive care, such as intravenous fluids, are also part of the treatment plan. Prompt and comprehensive treatment is essential to prevent the abscess from spreading or causing severe complications, such as airway obstruction, making early medical intervention crucial.


Parapharyngeal abscess is a condition that demands immediate medical attention. If you or someone you know experiences severe throat pain, swelling, or difficulty swallowing, it is crucial to seek medical care promptly. Diagnostic imaging, particularly CT scans plays an important role in confirming the diagnosis, enabling healthcare professionals to deliver appropriate treatment.
