[Videolaryngoscopy and videolaryngostroboscopy in phoniatrics]

Area of Science:

• Otolaryngology
• Speech-Language Pathology
• Medical Imaging

Background:

• Phoniatrics relies on accurate laryngeal assessment.
• Traditional laryngoscopy has limitations in dynamic vocal fold evaluation.
• Videolaryngoscopy (VLS) and videolaryngostroboscopy (VLSS) offer advanced visualization.

Purpose of the Study:

• To investigate the clinical utility of VLS and VLSS in phoniatrics.
• To assess the diagnostic capabilities of these imaging modalities for laryngeal pathologies.
• To explore their application in objective vocal cord analysis.

Main Methods:

• Examination of 150 patients with laryngeal lesions and 50 healthy subjects.
• Utilizing VLS and VLSS for laryngeal visualization.
• Objective measurement of vocal cord vibration, amplitude, frequency, and oscillation asynchronicity.

Main Results:

• VLS and VLSS provided objective data on vocal cord function in normal and pathological states.
• These techniques successfully identified functional and organic laryngeal diseases.
• Pre- and postoperative comparisons of laryngoscopic findings were facilitated.

Conclusions:

• VLS and VLSS are valuable tools for diagnosing and documenting laryngeal diseases.
• These methods enhance the evaluation of the vocal apparatus.
• Applications include biofeedback therapy and training in phoniatrics.
