Inferior pharyngeal constrictor muscle tendinitis is a condition where the tendon or the muscle-tendon junction of the inferior pharyngeal constrictor becomes inflamed. Although this type of tendinitis is less common than those affecting larger limb muscles, it can cause significant discomfort and swallowing difficulties.
Anatomy of the Inferior Pharyngeal Constrictor Muscle
Structure and Location
-
Location:
The inferior pharyngeal constrictor is one of the three muscles that form the muscular wall of the pharynx. It lies at the lower part of the throat, surrounding the pharynx and playing an essential role in swallowing. -
Parts of the Muscle:
This muscle is divided into two parts:-
Thyropharyngeus: Originates from the thyroid cartilage.
-
Cricopharyngeus: Originates from the cricoid cartilage.
-
Origin and Insertion
-
Origin:
-
Thyropharyngeus portion: Begins at the posterior aspect of the thyroid cartilage.
-
Cricopharyngeus portion: Begins at the lateral aspect of the cricoid cartilage.
-
-
Insertion:
Both parts converge and insert into the posterior wall of the pharynx, forming part of the muscular tube that facilitates the passage of food.
Blood Supply
-
Arterial Supply:
The muscle receives blood from branches of:-
The ascending pharyngeal artery.
-
Branches of the inferior thyroid artery.
-
Nerve Supply
-
Innervation:
The nerve supply comes primarily from the pharyngeal plexus, which includes:-
The vagus nerve (Cranial Nerve X) – mainly responsible for motor control.
-
Contributions from the glossopharyngeal nerve (Cranial Nerve IX) may also be involved.
-
Key Functions
-
Swallowing (Deglutition):
Helps propel food from the throat into the esophagus. -
Prevention of Regurgitation:
Contracts to keep food from moving back up. -
Airway Protection:
Works with other muscles to close off the airway during swallowing, preventing aspiration. -
Speech Articulation:
Supports proper movement of the pharyngeal walls, contributing to clear speech. -
Maintaining Pharyngeal Structure:
Provides structural integrity to the pharyngeal wall. -
Coordination with Other Muscles:
Works in tandem with the superior and middle pharyngeal constrictors to coordinate a smooth swallowing process.
Tendinitis refers to the inflammation or irritation of a tendon or the junction where muscle fibers meet tendons. In the case of the inferior pharyngeal constrictor, tendinitis may result from repetitive strain, injury, or underlying health issues, leading to pain and discomfort, especially during swallowing or speaking.
Types of Inferior Pharyngeal Constrictor Tendinitis
While research on this specific condition is limited, similar tendinopathies in small muscles can generally be classified as follows:
-
Acute Tendinitis:
A sudden inflammation often due to a direct injury or overuse. -
Chronic Tendinitis:
A long-term condition that develops due to repetitive stress or prolonged strain. -
Calcific Tendinitis:
Inflammation accompanied by the deposition of calcium in the tendon area. -
Infectious Tendinitis:
Occurs when an infection spreads to the muscle-tendon unit. -
Traumatic Tendinitis:
Results from direct injury or accidental trauma to the throat region.
Potential Causes
Here are 20 possible causes or contributing factors for inferior pharyngeal constrictor muscle tendinitis:
-
Overuse from Repetitive Swallowing:
Constant swallowing—especially in individuals with gastroesophageal reflux—can strain the muscle. -
Excessive Coughing:
Chronic cough can lead to repeated stress on throat muscles. -
Vocal Overuse:
Prolonged or excessive speaking/singing may strain the muscle. -
Direct Trauma:
Injury to the neck (e.g., during accidents or falls). -

Damage during or after endotracheal intubation in medical procedures. -
Pharyngitis:
Infection of the throat that may spread inflammation to nearby muscles. -

Sudden, involuntary muscle contractions that stress the tendon. -
Improper Swallowing Mechanics:
Poor technique or neurological conditions affecting swallowing. -
Smoking:
Irritates throat tissues and impairs healing. -
Excessive Alcohol Consumption:
