Throat clicking when swallowing is a common sensation, often accompanied by an audible sound. While frequently harmless, this article explores the reasons why your throat might click during swallowing, from normal anatomical movements to situations requiring medical attention.
Understanding the Mechanics of a Click
The throat contains several cartilages and bones that move in a coordinated manner during swallowing. These include the thyroid cartilage, which forms the Adam’s apple, and the cricoid cartilage, located just below it. The hyoid bone, a U-shaped bone in the neck, also plays a significant role, as it is the only bone in the human body not directly connected to another bone, instead supported by muscles and ligaments.
A clicking sound can arise when structures like the thyroid cartilage and hyoid bone move or rub against each other during swallowing. This movement creates friction, leading to a palpable or audible click. Air or fluid within the pharynx, the part of the throat behind the mouth and nasal cavity, can also contribute to popping sounds as they are displaced.
Muscle tension around the larynx, or voice box, can also influence these sounds. The muscles supporting the hyoid bone and larynx must contract and relax precisely for smooth swallowing. If these muscles are overly tense or spasm, the coordinated movement of cartilages and bones can be disrupted, potentially generating a clicking noise.
Common Explanations for Throat Clicking
Many instances of throat clicking are benign. The natural movement of laryngeal cartilages and the hyoid bone during swallowing is a common reason. As these structures shift to protect the airway and propel food, they can produce a sound similar to joints clicking elsewhere in the body, often noticeable when swallowing saliva in a quiet environment.
A dry throat can amplify these sounds. When the throat lacks sufficient lubrication, friction between moving structures increases, making clicking more pronounced. Swallowing air (aerophagia) can also trap air bubbles in the throat. As these bubbles burst or move during swallowing, they can create popping or clicking noises.
Muscle tension, often from stress or anxiety, can stiffen throat muscles. This tension alters swallowing mechanics, causing cartilages and bones to rub together more audibly. Minor anatomical variations, such as slight differences in hyoid bone or thyroid cartilage size or position, can also predispose individuals to more frequent clicking, even without an underlying problem.
When to Seek Medical Advice
While often harmless, certain symptoms with throat clicking warrant medical evaluation. Consult a healthcare professional if clicking is consistently painful or associated with difficulty swallowing (dysphagia). Other concerning signs include persistent hoarseness, voice changes, unexplained weight loss, or a sensation of a lump in the throat.
Anatomical abnormalities, such as an elongated or displaced thyroid cartilage or hyoid bone, can cause persistent clicking and pain. Rarely, conditions affecting the thyroid gland or temporomandibular joint (TMJ) dysfunction, which can refer pain to the throat, might also be considered.
What to Expect at the Doctor’s Office
If you seek medical attention for throat clicking, the diagnostic process begins with a review of your symptoms and medical history. Your doctor will perform a physical examination of your neck and throat, palpating the area to assess for tenderness, swelling, or to reproduce the clicking sound. This helps identify structural abnormalities or muscle tension.
Further tests might be recommended. A common procedure is a laryngoscopy, where a thin, flexible tube with a camera is inserted through the nose to visualize the throat and voice box. This allows observation of laryngeal structure movement during swallowing and checks for visible issues. Imaging scans, such as CT or MRI of the neck, may also provide detailed views of bones, cartilages, and soft tissues.
Depending on the diagnosis, management approaches can range from reassurance and observation to recommendations for speech therapy or, in rare cases, specific medical or surgical interventions if a treatable cause is identified.
