Passavant cushion cancer is a term sometimes used to describe cancer that affects the area around a small but important structure in the back of the upper throat. This structure—often called the Passavant cushion or Passavant’s ridge—is part of the nasopharynx, which plays a key role in swallowing and speech. Although the term is not common in everyday medical language, many of its features overlap with nasopharyngeal carcinoma (a cancer that develops in the nasopharynx). This guide covers the anatomy, types, causes, symptoms, diagnostic tests, non‐pharmacological treatments, drugs, surgeries, prevention strategies, and answers many frequently asked questions. The information provided here is evidence based and explained in very simple language.
Anatomy of the Passavant Cushion
Structure and Location
-
What is the Passavant Cushion?
It is a small, muscular pad located on the posterior (back) wall of the nasopharynx, just behind the soft palate. -
Where is it found?
The Passavant cushion is in the upper throat (nasopharynx). Its location is crucial during swallowing and speaking because it helps close off the nasal passage, ensuring that food and liquids move in the correct direction.
Origin and Insertion
-
Origin:
The Passavant cushion is created by the contraction of the superior pharyngeal constrictor muscle. Unlike bones and tendons, this structure does not have a typical “origin” and “insertion” but forms as a functional part of the throat’s musculature. -
Insertion:
It acts as a temporary, dynamic “cushion” during swallowing, helping to create a seal between the nasal cavity and the throat.
Blood Supply and Nerve Supply
-
Blood Supply:
The area receives blood from nearby branches such as the ascending pharyngeal artery. This blood flow is essential for the tissue’s health and function. -
Nerve Supply:
Nerves from the pharyngeal plexus (mainly branches of the vagus nerve, cranial nerve X) help control the muscles in this region, coordinating actions like swallowing and speech.
Key Functions of the Passavant Cushion
-
Swallowing Assistance:
It helps close off the nasal passage during swallowing to prevent food or liquid from entering the nasal cavity. -
Speech Production:
By aiding in the closure of the nasopharynx, it contributes to the correct resonance and clarity of your voice. -
Airway Protection:
It helps block unwanted material from entering the airway, reducing the risk of choking. -
Maintaining Nasopharyngeal Integrity:
The cushion supports the structural integrity of the nasopharynx. -
Preventing Nasal Regurgitation:
It stops food and liquids from backing up into the nose during swallowing. -
Facilitating Proper Resonance:
The structure plays a role in sound modulation and voice quality during speech.
Types of Passavant Cushion Cancer
Because the term “Passavant cushion cancer” overlaps with cancers of the nasopharynx, many of its types are similar to those seen in nasopharyngeal carcinoma. They include:
-
Squamous Cell Carcinoma:
-
Keratinizing Type: Cells produce keratin (a protein found in skin).
-
Non-Keratinizing Type: Cells do not produce keratin; these are more common in certain regions.
-
-
Undifferentiated Carcinoma:
The cancer cells do not look like normal cells and can be more aggressive. -
Basaloid Squamous Cell Carcinoma:
A less common variant with features of both squamous and basal cells.
Note: Many studies and clinical guidelines use the broader term “nasopharyngeal carcinoma” to describe these cancers.
Causes of Passavant Cushion Cancer
While the exact cause of cancer in the nasopharyngeal area is complex, several factors are known to contribute. Here are 20 potential causes or risk factors explained in simple terms:
-
Epstein-Barr Virus (EBV) Infection:
A common virus linked to many cases of nasopharyngeal cancer. -
Genetic Predisposition:
A family history of cancer can increase risk. -

Long-term exposure in certain jobs can increase risk. -
High Salt Intake:
Diets high in salted fish or processed foods are linked to higher risk. -
Chronic Inflammation:
Ongoing inflammation in the throat can lead to changes in cells. -
Radiation Exposure:
Past exposure to radiation (for example, from other medical treatments) may raise risk. -
Air Pollution:
Polluted air may contain carcinogenic particles. -
Occupational Hazards:
Jobs that expose workers to chemicals or dust can be a risk factor. -
Poor Oral Hygiene:
Not keeping the mouth and throat clean may increase cancer risk. -
Viral Co-Infections:
Other viral infections alongside EBV might contribute. -
Age-Related Cellular Changes:
The risk increases as cells naturally age. -
Immune System Dysfunction:
A weakened immune system might not catch early cancerous changes. -
Family History of Cancer:
Genetics can play a significant role. -
Socioeconomic Factors:
Limited access to healthy foods and healthcare can contribute. -
Hormonal Imbalances:
Changes in hormones may influence cell growth. -
Lifestyle Factors:
A sedentary lifestyle and poor diet can increase overall cancer risk.
