The superior pharyngeal constrictor muscle is a key muscle in the throat that helps with swallowing and protects the airway. When this muscle is strained or sprained, it can lead to pain and difficulty with normal functions such as swallowing and speaking. In this guide, you will find simple explanations about its anatomy, types of sprains, causes, symptoms, diagnostic tests, treatment options (both non-pharmacological and drugs), surgical options, prevention tips, when to see a doctor, and answers to frequently asked questions.
Anatomy of the Superior Pharyngeal Constrictor Muscle
Understanding the basic anatomy helps in knowing how an injury may affect your functions.
Structure & Location
-
Location:
The superior pharyngeal constrictor muscle is located in the upper part of the throat (pharynx), forming part of its lateral and posterior walls. -
Structure:
It is a thin, quadrilateral (four-sided) muscle that wraps around the pharynx.
Origin & Insertion
-
Origin:
The muscle starts from several areas, including:-
The pterygomandibular raphe (a fibrous band in the mouth area)
-
The pterygoid hamulus (a small hook-like projection from the sphenoid bone)
-
The alveolar process of the mandible (the bony ridge that holds the teeth)
-
-
Insertion:
The muscle fibers run downward and inward to converge into the midline, where they attach to the pharyngeal raphe (a tendinous band running along the back of the throat).
Blood Supply
-
The superior pharyngeal constrictor receives blood from branches of arteries in the neck, such as:
-
The ascending pharyngeal artery
-
Possibly small branches from nearby facial or other pharyngeal arteries
-
Nerve Supply
-
Nerve Supply:
The muscle is mainly controlled by the pharyngeal branch of the vagus nerve (cranial nerve X), which helps coordinate its actions during swallowing and speaking.
Functions ( Key Functions)
-
Initiates Swallowing:
By contracting, it helps push food down the throat. -
Prevents Nasal Regurgitation:
It aids in closing off the nasal passages during swallowing so that food does not go into the nose. -
Supports the Pharyngeal Wall:
It maintains the structure of the throat. -
Protects the Airway:
Its contraction helps prevent aspiration (food entering the windpipe). -
Assists in Speech:
It plays a role in shaping sounds by influencing the throat’s structure. -
Stabilizes the Larynx:
It helps keep the voice box in proper position during movement.
Types of Superior Pharyngeal Constrictor Muscle Sprain
While muscle injuries are more commonly described as strains, the term “sprain” may be used to describe the overstretching or tearing of muscle fibers. They can be classified as:
-
Grade I (Mild):
Minor stretching with minimal tearing; discomfort is usually slight. -
Grade II (Moderate):
Partial tearing of the muscle fibers; pain and swelling are more pronounced. -
Grade III (Severe):
A complete tear of the muscle fibers; significant pain, weakness, and loss of function may occur. -
Acute vs. Chronic:
-
Acute: Injury that occurs suddenly.
-
Chronic: Injury that develops over time due to repetitive strain or overuse.
-
Even though sprains in this specific muscle are less common than in other parts of the body, injuries can be classified by severity and cause:
-
Mild Sprain:
Slight overstretching of muscle fibers without significant tearing. -
Moderate Sprain:
More noticeable tearing of muscle fibers leading to pain and reduced function. -
Severe Sprain:
Extensive damage to the muscle, potentially affecting nearby tissues. -
Acute Sprain:
A sudden injury, often from a direct blow or abrupt movement. -
Chronic Sprain:
An injury that worsens over time due to repetitive strain or overuse. -
Direct Trauma vs. Overuse Injury:
Injuries caused by a single incident versus those resulting from repeated strain.
