Retropharyngeal hematoma is a condition characterized by the accumulation of blood in the space located behind the throat. This collection of blood can compress nearby structures and cause difficulty with breathing or swallowing.
The primary health risk of a retropharyngeal hematoma is airway obstruction. As the hematoma enlarges, it can narrow the airway or food passage and lead to serious complications that require prompt medical attention.
What Are the Types of Retropharyngeal Hematoma?
Retropharyngeal hematomas can occur in several forms depending on the underlying cause. Each type may require a different treatment approach.
- Spontaneous Retropharyngeal Hematoma: A rare condition characterized by the sudden accumulation of blood in the retropharyngeal space without any apparent injury or trauma.
- Traumatic Retropharyngeal Hematoma: Caused by direct trauma to the neck or throat area, leading to bleeding and hematoma formation in the retropharyngeal space.
- Iatrogenic Retropharyngeal Hematoma: Occurs as a complication of medical procedures such as intubation, endoscopy, or surgery involving the throat or upper airway.
- Coagulopathy-Related Retropharyngeal Hematoma: Associated with bleeding disorders or conditions that affect the blood's ability to clot properly.
- Inflammatory Retropharyngeal Hematoma: Results from inflammatory conditions such as infections or autoimmune disorders that damage blood vessels and cause bleeding.
What Are the Symptoms of Retropharyngeal Hematoma?
Retropharyngeal hematoma symptoms can develop gradually or rapidly depending on the amount of bleeding. Common symptoms include difficulty in swallowing, neck pain, swelling, and breathing problems.
- Difficulty Swallowing: Compression of the throat can make it difficult or painful to swallow food, liquids, or saliva.
- Neck Pain: Pain may develop in the front or back of the neck.
- Neck Stiffness: Swelling and pressure can restrict normal neck movement.
- Voice Changes: The voice may become hoarse, muffled, or unusually weak.
- Breathing Difficulty: An expanding hematoma can narrow the airway and cause breathing difficulty.
- Neck Swelling: Visible or increasing swelling may develop as blood accumulates behind the throat.
What Causes a Retropharyngeal Hematoma?
Retropharyngeal hematoma is commonly caused by trauma to the neck, bleeding disorders, medical procedures, or medicines that affect blood clotting. In some cases, the condition develops without an obvious cause.
- Trauma: Motor vehicle accidents, falls, or sports injuries can damage blood vessels in the neck.
- Coagulopathy: Coagulopathy can impair normal blood clotting and increase the risk of spontaneous bleeding.
- Invasive Medical Procedures: Intubation, endoscopy, surgery, or other procedures involving the throat or neck may injure blood vessels.
- Anticoagulant Medication Use: Medicines that reduce blood clotting can increase the risk of bleeding into the retropharyngeal space.
- Blood Vessel Abnormalities: Abnormal or weakened blood vessels may rupture and cause a hematoma.
When to See a Doctor for Retropharyngeal Hematoma?
Medical evaluation is important for new neck swelling, swallowing difficulty, voice changes, or breathing problems, especially after trauma or a medical procedure. A general surgeon usually treats retropharyngeal hematoma, with support from emergency physicians, surgeons, and haematologists when needed.
You should see a doctor if you have:
- Persistent neck pain, stiffness, or swelling
- New difficulty swallowing food, liquids, or saliva
- Voice changes after neck trauma or a medical procedure
Get medical help immediately if:
- You develop difficulty breathing or rapidly worsening breathlessness
- Neck swelling increases quickly or you cannot swallow saliva
- You develop severe weakness, fainting, or signs of significant bleeding
These could be signs of a serious complication like airway obstruction, which needs urgent care.
How Is Retropharyngeal Hematoma Diagnosed?
Diagnosing a retropharyngeal hematoma usually involves a physical examination and imaging tests to identify the location and extent of bleeding. Early diagnosis is important because the hematoma can rapidly compress the airway.
Physical Examination
A doctor examines the neck and throat for swelling, tenderness, stiffness, voice changes, and signs of breathing difficulty. The patient's history of trauma, surgery, medication use, or bleeding disorders is also reviewed.
Computed Tomography Scan
A CT scan can show the size and location of the hematoma and determine whether it is compressing the airway or nearby structures.
Magnetic Resonance Imaging
MRI may provide detailed images of the soft tissues in the neck and help assess the extent of the hematoma.
Throat Endoscopy
Throat endoscopy may be used to examine the upper airway and assess the degree of compression or swelling.
Laboratory Tests
Blood tests may be performed to check hemoglobin levels, platelet counts, and blood clotting function, especially in people with suspected bleeding disorders or anticoagulant use.
How Is Retropharyngeal Hematoma Treated?
Treatment for retropharyngeal hematoma depends on the size of the hematoma, severity of symptoms, underlying cause, and whether the airway is affected. Prompt treatment is important to prevent airway obstruction and other serious complications.
Airway Support
Protecting the airway is the first priority when breathing is affected. Oxygen or advanced airway support may be required if swelling causes significant airway narrowing.
Observation and Monitoring
Small and stable hematomas may be managed with close monitoring. Doctors regularly assess breathing, swallowing, neck swelling, and the size of the hematoma.
Correction of Bleeding Problems
Anticoagulant medicines may need to be temporarily stopped or reversed under medical supervision. Treatment may also be given to correct underlying clotting disorders.
Surgical Drainage
Large or expanding hematomas that threaten the airway or compress nearby structures may require surgical drainage.
Antibiotics
Antibiotics may be prescribed when there is a risk of infection or contamination, although they are not required for every retropharyngeal hematoma.

What Are the Risk Factors for Retropharyngeal Hematoma?
Certain conditions, medicines, injuries, and medical procedures can increase the likelihood of bleeding in the retropharyngeal space.
- Trauma to the neck or head
- Use of anticoagulant medications
- Bleeding disorders
- Recent surgery in the neck region
- Inflammatory conditions affecting the throat or neck
- History of radiation therapy to the neck
- Invasive medical procedures involving the throat or neck
What Are the Complications of Retropharyngeal Hematoma?
Retropharyngeal hematoma can cause serious complications when bleeding continues or the collection of blood becomes large enough to compress nearby structures.
- Airway Obstruction: An expanding hematoma can narrow or completely block the airway.
- Difficulty Swallowing: Compression of the throat can interfere with swallowing food, liquids, and saliva.
- Respiratory Distress: Severe airway narrowing can cause low oxygen levels and life-threatening breathing problems.
- Blood Loss: Ongoing internal bleeding may cause anemia, weakness, or circulatory instability.
- Infection: The collected blood can rarely become infected and lead to further complications.
Frequently Asked Questions
1. Can Retropharyngeal Hematoma cause long-term effects?
If not properly treated, Retropharyngeal Hematoma can lead to complications like chronic swallowing difficulties, airway obstruction, or scarring. Early intervention helps reduce the risk of long-term problems.
2. Is Retropharyngeal Hematoma common in children?
Retropharyngeal Hematoma is rare in children, but trauma from accidents or falls can lead to this condition. Prompt medical attention is necessary to prevent complications.
3. Is Retropharyngeal Hematoma a life-threatening condition?
Yes, if left untreated, Retropharyngeal Hematoma can lead to severe airway obstruction, which can be life-threatening. Immediate medical attention is essential to prevent complications.
4. Can Retropharyngeal Hematoma resolve without treatment?
Mild cases of Retropharyngeal Hematoma may resolve on their own with observation. However, severe cases require medical intervention to prevent complications like airway obstruction or infection.
5. Can Retropharyngeal Hematoma cause difficulty speaking?
Yes, Retropharyngeal Hematoma can affect the voice, leading to hoarseness or voice changes. This occurs when the hematoma puts pressure on the vocal cords or surrounding structures.
6. Can Retropharyngeal Hematoma be prevented?
While trauma and certain medical procedures may increase the risk, it's difficult to fully prevent Retropharyngeal Hematoma. Proper care during surgeries, avoiding neck injuries, and managing bleeding disorders can reduce risk.
