Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Physical Assessment of the Respiratory Tract IV: Auscultation01:28

Physical Assessment of the Respiratory Tract IV: Auscultation

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
Actor-Observer Effect01:23

Actor-Observer Effect

The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in visual...
Respiratory System Abnormal Finding II: Palpation and Auscultation01:31

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Air-entraining Agents01:27

Air-entraining Agents

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...
Pharynx01:20

Pharynx

The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Summary

Vocal pathologies are common in acting students, with over half experiencing issues like incomplete glottal closure and laryngeal hyperfunction. Laryngopharyngeal reflux was also prevalent, particularly in those with hyperfunctioning voices.

Area of Science:

  • Vocal health
  • Performing arts medicine
  • Speech-language pathology

Background:

  • Actors face unique vocal demands impacting vocal health.
  • Understanding vocal pathology prevalence is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence of vocal pathology in first-year acting students.
  • To identify specific laryngeal abnormalities and their correlation with vocal function.

Main Methods:

  • Retrospective review of 30 graduate-level acting students (2009-2011).
  • Analysis of videostroboscopy, Voice Handicap Index-10 (VHI-10), and acoustic measures.
  • Subgroup analysis comparing hyperfunctioning and non-hyperfunctioning students.

Main Results:

  • High prevalence of incomplete glottal closure (62%), laryngeal hyperfunction (59%), and decreased mucosal wave (55%).
  • Laryngopharyngeal reflux (LPR) observed in 48% of subjects.
  • Significantly higher prevalence of videostroboscopic abnormalities and LPR stigmata in hyperfunctioning actors (P=0.04).

Conclusions:

  • Acting students exhibit significant vocal pathology, including hyperfunction and LPR.
  • Vocal training and feedback are essential to improve outcomes for actors.
  • This study provides foundational data for ongoing vocal health monitoring in performing arts education.
