Superior pharyngeal constrictor muscle strain is an injury or overuse of a key throat muscle that plays an important role in swallowing, speaking, and protecting your airway. In this guide, we break down the anatomy of the muscle, explore the different ways it can be injured, list causes and symptoms, review many tests and treatment options, and offer advice on prevention and when to seek medical care.
Anatomy of the Superior Pharyngeal Constrictor Muscle
The superior pharyngeal constrictor muscle is one of the main muscles forming the wall of your pharynx (the throat area). Here are its key details:
Location and Structure
-
Where it is: This muscle is located at the upper part of your pharynx. It forms a curved wall that helps close off the throat during swallowing.
-
Role: It is one of several muscles that work together to push food from the mouth into the esophagus.
Origin and Insertion
-
Origin: The muscle originates from several structures:
-
Pterygomandibular raphe: A fibrous band that stretches between the jaw and the pterygoid process of the sphenoid bone.
-
Medial pterygoid plate: Part of the sphenoid bone.
-
Posterior end of the mylohyoid line of the mandible: The bony ridge on the inner side of the lower jaw.
-
-
Insertion: It extends to merge into a midline fibrous raphe (a tendon-like band) that runs down the back of the pharynx.
Blood Supply
-
Arterial Supply: The muscle receives blood primarily from branches of the external carotid artery, such as the ascending pharyngeal artery.
Nerve Supply
-
Innervation: The superior pharyngeal constrictor is mainly controlled by the pharyngeal branch of the vagus nerve (cranial nerve X) via the pharyngeal plexus.
Key Functions
-
Swallowing: Constricts the pharyngeal walls to help push food into the esophagus.
-
Speech Production: Contributes to the proper resonance of your voice.
-
Airway Protection: Helps close the passage between the nose and throat during swallowing, preventing food from entering the nasal cavity.
-
Structural Support: Maintains the shape and integrity of the pharyngeal wall.
-
Assisting in Breathing: Works with other muscles to manage the balance between air and food pathways.
-
Coordinating with Other Muscles: Works in tandem with other pharyngeal muscles to ensure smooth, coordinated movements during swallowing.
Types of Superior Pharyngeal Constrictor Muscle Strain
While specific classifications for this type of strain may not be as well known as strains in larger skeletal muscles, similar principles apply:
-
Acute Strain: Sudden injury from an abrupt overuse or trauma.
-
Chronic Strain: Develops over time due to repetitive overuse (e.g., prolonged speaking, singing, or coughing).
-
Traumatic Strain: Results from a direct injury or accident that impacts the throat region.
-
Overuse Strain: Occurs with repeated, excessive movement or stress (such as vocal abuse or constant throat clearing).
Causes of Superior Pharyngeal Constrictor Muscle Strain
Here are 20 potential causes that can lead to a strain of the superior pharyngeal constrictor muscle:
-
Excessive Talking or Singing: Overuse can tire the throat muscles.
-
Vocal Strain: Shouting or speaking loudly for long periods.
-
Prolonged Coughing: Continuous coughing can stress the throat.
-
Intubation: Medical procedures like intubation can injure the muscle.
