A physical assessment of the muscles around the larynx to identify tension and assess voice quality.
What does normal laryngeal muscle palpation feel like?
What does normal laryngeal muscle palpation feel like?

Study Notes
Muscle Imbalance in Myofacial Dysphonia (MTD)
- Intrinsic and extrinsic laryngeal muscle imbalance is a primary characteristic of MTD.
- Manual examination of laryngeal musculoskeletal tension rapidly assesses muscle tension's role in voice quality.
- This differentiation aids in accurate diagnosis and treatment planning.
Manual Examination Protocols
- Examination includes palpation of suprahyoid muscles, hyoid bone horns, thyroid cartilage, thyrohyoid space, and sternocleidomastoid muscle.
- Suprahyoid tension and thyrohyoid space are assessed at rest and during phonation, along with lateral mobility.
- Some protocols include palpation of thyrohyoid, cricothyroid, and pharyngolaryngeal (inferior constrictor and posterior cricoarytenoid) muscles.
- Normal findings involve palpable space between the hyoid and thyroid cartilage, and laryngeal mobility.
- Abnormal findings include one-sided pain, reduced/absent thyrohyoid space (at rest or during phonation), muscle knots, high hyoid/thyroid carriage, and difficulty laterally moving the larynx.
Reliability and Radiographic Studies
- Intra- and inter-examiner reliability data for manual tension examination are currently unavailable.
- Sensitivity and specificity of abnormal findings are unknown.
- Radiographic studies of laryngeal position in MTD show no difference in hyoid/thyroid cartilage location at rest between control participants and those with MTD.
- During phonation, control participants lower their hyoid more than participants with MTD, and MTD participants raise their thyroid cartilage more.
