Exam
B) Incomplete closure and breathy voice C) Hyperfunction of the posterior glottis D) Increased mucosal wave speed Answer: B Explanation: The anchored epithelium prevents full medial contact, creating a persistent gap. Question 21. Granulomas on the vocal process are most often related to which triad? A) Smoking, alcohol, and reflux B) Reflux, intubation, and vocal misuse C) Allergy, infection, and trauma D) Aging, hormonal changes, and dehydration Answer: B Explanation: The combination of LPR, prolonged intubation, and phonotrauma predisposes to granuloma formation. Question 22. Contact ulcers typically form on which anatomical landmark? A) Anterior commissure B) Vocal process of the arytenoid C) Posterior subglottis D) Subglottic trachea Answer: B Explanation: The vocal process is the point of maximal contact during phonation, making it prone to ulceration.
Exam

Exam
Explanation: Talbot’s law describes how stroboscopic illumination creates the illusion of slow motion. Question 29. In stroboscopic evaluation, a “hourglass” closure pattern indicates: A) Complete closure with symmetrical vibration B) A posterior gap with anterior contact C) A central gap surrounded by lateral contact D) Irregular, chaotic vibration Answer: C Explanation: The hourglass shape reflects a central (mid‑membranous) gap while the lateral edges meet. Question 30. Which stroboscopic parameter assesses the regularity of each vibratory cycle? A) Amplitude B) Periodicity C) Symmetry D) Phase lag Answer: B Explanation: Periodicity refers to the consistency of the cycle-to-cycle timing of vibration. Question 31. A decreased mucosal wave amplitude on stroboscopy most likely corresponds to: A) Vocal fold atrophy B) Vocal fold stiffness from a cyst or edema C) Normal aging D) Hyperfunctional MTD without structural lesion

The s/z ratio is an aerodynamic measure that assesses: A) Phonation frequency range B) Glottal efficiency and respiratory support C) Vocal fold closure strength D) Subglottic pressure only Answer: B Explanation: The s/z ratio compares the duration of voiceless /s/ to voiced /z/; an elevated ratio suggests inefficient phonation. Question 36. Maximum phonation time (MPT) is most directly affected by: A) Vocal fold length B) Respiratory support and glottic efficiency C) Pitch of the voice D) Presence of vocal nodules only Answer: B Explanation: MPT reflects how long a person can sustain phonation with a single breath, depending on breath support and efficient glottic closure.
