Summary
Videostrobokymography objectively assesses vocal fold vibration, revealing significant Open Quotient differences in patients with Reinke edema and vocal cord paralysis. This technique aids in differentiating voice disorders.
Area of Science:
- Laryngology and phoniatrics
- Bioacoustics and voice analysis
Context:
- Videostrobokymography (VSKG) offers objective assessment of vocal fold vibration.
- Traditional stroboscopy lacks objective vibratory parameter measurement.
- VSKG analyzes specific glottal regions for detailed vibration insights.
Purpose:
- To evaluate objective vocal fold vibration parameters using VSKG.
- To compare VSKG parameters in patients with various voice disorders versus healthy controls.
- To identify VSKG's utility in differential diagnosis of dysphonia.
Summary:
- The study measured Open Quotient (OQ) in 82 patients with voice disorders and healthy controls.
- Significant OQ differences were found between control and patient groups.
- VSKG revealed statistically significant OQ variations in Reinke edema and vocal cord paralysis patients across different vocal fold regions.
Impact:
- VSKG provides objective data complementing stroboscopy.
- Objective vibratory parameters enhance diagnostic accuracy for voice disorders.
- VSKG proves valuable in the differential diagnosis of functional and organic dysphonia.

Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

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.

Physical Assessment of the Respiratory Tract III: Percussion
The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
