A pharyngeal muscles sprain is an injury to the muscles located in the pharynx (the part of the throat behind the mouth and nasal cavity). Although more commonly discussed in the context of limb or back injuries, the pharyngeal muscles can also experience strains or sprains due to overuse, trauma, or other causes. This guide provides evidence-based details on the anatomy, causes, symptoms, diagnosis, treatment options, prevention strategies, and answers common questions about pharyngeal muscles sprain.
Anatomy of the Pharyngeal Muscles
Understanding the structure and function of the pharyngeal muscles is key to recognizing how a sprain can affect throat function.
Structure and Location
-
Location: The pharyngeal muscles are located in the throat (pharynx), stretching from the base of the skull to the upper part of the esophagus.
-
Main Muscles:
-
Superior Pharyngeal Constrictor: Located near the upper part of the pharynx.
-
Middle Pharyngeal Constrictor: Positioned in the middle of the pharynx.
-
Inferior Pharyngeal Constrictor: Found in the lower pharynx.
-
Additional Muscles: Muscles such as the stylopharyngeus, palatopharyngeus, and salpingopharyngeus contribute to the overall function.
-
Origin and Insertion
-
Origin: Each muscle begins at specific bony or cartilaginous points.
-
For example, the superior constrictor originates from structures such as the pterygoid hamulus and the pterygomandibular raphe.
-
-
Insertion: Muscles insert into connective tissues like the pharyngeal raphe, forming a continuous muscular tube that plays a role in swallowing and speech.
Blood Supply
-
Primary Sources:
-
Branches from the ascending pharyngeal artery.
-
Contributions from the facial artery (specifically the tonsillar branch).
-
Branches from the inferior thyroid artery also provide blood supply.
-
Nerve Supply
-
Pharyngeal Plexus: The muscles are primarily controlled by nerves from the pharyngeal plexus, which includes:
-
The vagus nerve (cranial nerve X)
-
The glossopharyngeal nerve (cranial nerve IX)
-
-
These nerves help coordinate muscle movements for swallowing, speaking, and protecting the airway.
Primary Functions of the Pharyngeal Muscles
-
Swallowing: They contract to help push food from the mouth into the esophagus.
-
Speech Production: These muscles aid in modulating sound and ensuring proper resonance.
-
Airway Protection: They work to prevent food and liquids from entering the windpipe during swallowing.
-
Facilitating Breathing: Although not directly involved in breathing, they help maintain an open airway.
-
Regulating Esophageal Opening: By controlling the passage of food, they assist in preventing reflux.
-
Supporting Postural Stability: They contribute to the overall structure and stability of the neck region.
Types of Pharyngeal Muscles Sprain
While sprains are typically categorized by severity and cause, pharyngeal muscles sprain can be classified as follows:
-
Mild Sprain:
-
Minor stretching or microscopic tears in the muscle fibers.
-
May cause slight discomfort or a mild sore throat.
-
-
Moderate Sprain:
-
Greater muscle fiber involvement with more noticeable pain and swelling.
-
Can affect swallowing and speaking.
-
-
Severe Sprain:
-
Significant tearing of muscle fibers.
-
Often results in intense pain, marked swelling, and may significantly impair normal functions.
-
-
Acute vs. Chronic:
-
Acute: A sudden injury resulting from trauma or overexertion.
-
Chronic: Ongoing or repeated strain that causes persistent discomfort over time.
-
Causes of Pharyngeal Muscles Sprain
Here are 20 potential causes that may lead to a sprain of the pharyngeal muscles:
-
Overuse from excessive talking or singing – prolonged voice use without rest.
-
Improper swallowing techniques – such as rapid or forceful swallowing.
-
Trauma from intubation – injuries during medical procedures.
-
Physical impact during sports – especially contact sports.
-
Whiplash injuries – sudden neck movements that strain throat muscles.
-
Repetitive strain injuries – due to chronic poor posture or repetitive tasks.
-
Acute infections – such as severe pharyngitis that inflames the muscle tissue.

-
Laryngopharyngeal reflux (LPR) – similar to GERD but affecting the throat.
-
Viral infections – which may cause muscle inflammation.
-
Bacterial infections – leading to abscess formation and muscle stress.
-
Excessive coughing – forceful or chronic coughing can strain muscles.
-
Voice misuse or abuse – shouting, yelling, or improper vocal training.
-
Stress-related muscle tension – psychological stress manifesting as muscle tightness.
-
Post-surgical complications – following throat or neck surgeries.
-
Accidental blows or impacts – from falls or accidents.
-
Chronic sinusitis – can lead to compensatory muscle strain.
-
Nutritional deficiencies – poor nutrition affecting muscle repair.
-
Environmental irritants – such as smoke or chemical fumes.
-
Underlying muscular disorders – that predispose the muscles to injury.
