Throat Clicking While Swallowing: Causes
Throat clicking during swallowing is most commonly caused by mechanical friction between the superior cornu of the thyroid cartilage and the hyoid bone, or between these structures and the cervical spine—a condition known as "clicking larynx syndrome." 1, 2
Primary Anatomical Causes
The clicking larynx syndrome results from specific structural abnormalities:
- Displaced or elongated superior cornu of the thyroid cartilage projecting posteriorly and medially 2
- Enlarged greater cornu of the hyoid bone 1
- Reduced distance between thyroid cartilage and hyoid bone 1
- Thyroid cartilage or vertebral body asymmetry 2
These anatomical variations cause the cartilaginous structures to collide during swallowing or head/neck movements, producing an audible and often palpable click 3, 1.
Clinical Presentation
Patients typically describe:
- Clicking or popping sensation in the throat during swallowing
- Symptoms provoked by head/neck movement or circumlaryngeal manipulation 4
- Associated neck and throat pain (though clicking can occur without pain) 2
- Tender area in the neck 1
Important distinction: The clicking described in clicking larynx syndrome differs from normal intra-aural swallowing click sounds, which are produced by Eustachian tube opening/closing and occur in healthy individuals without pathology 5.
Risk Factors and Associated Conditions
- Obesity may contribute to symptoms 3
- Hormonal changes (e.g., testosterone therapy increasing thyroid cartilage size) 3
- Prior laryngeal trauma (though rarely reported) 4
Diagnostic Approach
Physical examination is paramount: Palpate the neck while the patient swallows to localize the side and source of clicking 2. This simple maneuver is often more diagnostic than imaging.
Advanced imaging when diagnosis remains unclear:
- Swallowing CT with virtual reality reconstruction provides definitive visualization of cartilage collision during dynamic swallowing 3
- Laryngeal CT scans may demonstrate thyroid cartilage or vertebral asymmetry 2
- Standard laryngoscopy and conventional swallowing examinations are typically normal 3
Common Pitfall
Do not dismiss these symptoms as psychogenic. The clicking throat is a real, surgically treatable anatomical problem that significantly impacts quality of life 2, 6. Patients are often anxious and perplexed by the strange clicking, and identifying the cause—even without treatment—can substantially improve patient satisfaction 3.
Treatment Options
Surgical resection of the offending cartilaginous structure (typically the superior cornu of thyroid cartilage or greater horn of hyoid bone) via thyroplastic surgery successfully eliminates symptoms in all reported surgical cases 2, 4.
For mild cases without severe pain: Explanation of the underlying anatomical cause may be sufficient and can avert surgery 1. Conservative management with weight loss may improve symptoms in obese patients 3.
