Video post. Discussion with a colleague about vocal cord weakness — reviewing how to identify LCA paresis by focusing on the movement and position of the vocal processes. YouTube link.
Migration note: Connects to the Neurolaryngology section (Part II Structural) and Part III Laryngoscopy.
Home›Clinical & Educational›UEP Podcast — Identifying Voice Disorders Podcast with Dr. Shiying Hey (Union of European Phoniatricians). Topics: background in laryngology starting in high school with physics/sound; three-part diagnostic approach (history, voice examination, endoscopy); compensatory behaviors; lifestyle factors (coffee, alcohol); references the 2012 book and voicedoctor.net. Download link included.
Home›Clinical & Educational›Can Someone Have a Voice Without Vocal Cords? Story of patient Mary Marlboro — larynx removed for cancer, used electrolarynx then developed esophageal phonation. Voice = sound source + amplifying resonator (no vocal cords required). The two fundamental characteristics of voice: pitch and volume. Wind chimes metaphor. References the book. Migration note: Part…
Home›Clinical & Educational›A Standard Examination of the Human Voice Standard Laryngeal Examination — An adequate assessment of the human voice, particularly pre- and post-surgery. Ideally two parts: audio recording and visual endoscopic examination including stroboscopy. Audio examination parameters: Speech (10-second standard reading passage), Maximum phonation time at comfortable pitch, Lowest pitch (stepwise glide), Highest pitch…
Home›Clinical & Educational›What Is Voice? Faith N. Metsan’s first appearance — voice disappears suddenly over an afternoon. Dr. Marcus Goodew doesn’t look at vocal cords. Defines voice: “a sound produced by vibration and amplified by resonance; no vocal cords are required.” Violin analogy — anything vibrating in audible range has a voice. Two components: sound…
Home›Clinical & Educational›Compensating for Hoarseness How natural compensation hides voice disorders during examination, both audibly and visually. Two examples: (1) TA muscle weakness — CT muscle compensates by raising pitch. Examiner removes compensation by asking patient to progressively lower pitch, revealing the bowing/flutter of the weak cord. (2) Mucosal swellings — patient raises volume at…
Home›Clinical & Educational›Anatomy of the Voice Box Accessible anatomy introduction. Three functions of the larynx: regulate breathing, create sound, keep food out of lungs. Describes thyroid cartilage (Adam’s apple), cricoid cartilage, hyoid bone, and how testosterone thickens/elongates vocal cords lowering pitch. Written from a café observation scene with a Japanese-speaking couple. References the book. Migration…
