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.
