Phoniatrics and Voice Disorders Practice Questions

Q: Representation of pitch and loudness, a profile of the fundamental frequency (Hz) and intensity (dB), is referred to as:

Phonetogram. ***Phonetogram*** - A phonetogram, also known as a **voice range profile**, visually plots the **pitch** (fundamental frequency, in Hertz) against the **loudness** (intensity, in decibels) of the human voice. - It helps assess the **vocal range** and quality, often used in diagnosing and monitoring voice disorders. *Phonogram* - A phonogram is a **recording of sound**, not specifically a graphical representation of pitch and loudness ranges. - For example, a **heart sound recording** is a type of phonogram, showing sound intensity over time. *Phoneme* - A phoneme is the **smallest unit of sound** in a language that can distinguish one word from another (e.g., 'p' in 'pat' vs. 'b' in 'bat'). - It is a linguistic concept, not a tool for measuring vocal range or intensity. *None of the options* - This option is incorrect as "Phonetogram" accurately describes the specified representation.

Q: All of the following are true about spasmodic dysphonia except which of the following?

It is not a type of focal laryngeal dystonia.. ***Correct Answer: "It is not a type of focal laryngeal dystonia" - This statement is FALSE (the exception)*** - **Spasmodic dysphonia IS a form of focal laryngeal dystonia**, characterized by involuntary spasms of the laryngeal muscles during speech. - Its classification as a **dystonia** underscores its neurological origin affecting specific muscle groups. - This is the correct answer because the question asks for the FALSE statement ("except"). *Incorrect Option: "It may be of adductor or abductor type" - This is TRUE* - **Spasmodic dysphonia** can present in two main forms: **adductor spasmodic dysphonia** and **abductor spasmodic dysphonia**. - These types are distinguished by whether the vocal folds spasm in an adducted (closed) or abducted (open) position. *Incorrect Option: "Abductor type is characterized by a breathy quality of voice" - This is TRUE* - In **abductor spasmodic dysphonia**, abrupt, involuntary spasms cause the vocal folds to open too widely, leading to air escaping during phonation. - This excessive air leakage results in a **breathy** or whispered voice quality, often with voice breaks. *Incorrect Option: "Adductor type is characterized by a strained or strangled voice" - This is TRUE* - **Adductor spasmodic dysphonia** involves involuntary spasms that cause the vocal folds to clamp shut too tightly and frequently. - This excessive vocal fold adduction results in a **strained, strangled, or choked** vocal quality, with sudden voice stoppages.
