Laryngeal palpation and the anterior surface of the neck is carried out at the usual position of the head and when it is thrown back while assessing the relief of the palpable region.
Protrusions and hollows of the pre-laryngeal space:
- Body of the hyoid bone
- Thyrohyoideus cavity
- Laryngeal prominence (Adam's apple)
- Intercricoid-thyroid cavity
- Protruding arch of cricoid cartilage
- Epiglottis protrusion, formed by the first rings of the trachea
- Supragastral cavity
- The hyoid bone
- Thyroid cartilage
- Cricoid cartilage
With superficial palpation of the larynx, the consistency, mobility, and turgor of the skin covering the larynx and adjacent areas are evaluated. With deep palpation, examine the area of the hyoid bone, the space around the corners of the lower jaw, then descend along the anterior and posterior margin of the sternocleidomastoid muscle, determining the condition of the lymph nodes. Palpate supraclavicular fossa and areas of attachment of the sternocleine-mastoid muscle, lateral and occipital surfaces of the neck and only then pass to the palpation of the larynx. It is covered on both sides by the fingers of both hands, sorting through its elements. Assess the shape, consistency, determine the possible presence of soreness and other sensations. Then move the larynx to the right and left, assessing its mobility, as well as the possible presence of sound phenomena - a crunch (with fractures of cartilage), crepitations (with emphysema). When palpation, the areas of the cricoid cartilage and conical ligament often reveal the isthmus of the thyroid gland covering them. Feeling the jugular fossa, the patient is asked to do a swallowing movement: in the presence of an ectopic thyroid lobe, a jerk can be felt.
