[EGG used in laryngeal diseases]

Area of Science:

• Otolaryngology
• Medical instrumentation
• Diagnostic imaging

Context:

• Laryngeal diseases encompass a range of conditions affecting the voice box, including vocal polyps, nodules, paralysis, cancer, and Reinke's edema.
• Accurate diagnosis is crucial for effective treatment and patient outcomes.
• Current diagnostic methods may have limitations in providing objective, quantitative data.

Purpose:

• To analyze Electroglottography (EGG) parameters in patients with various laryngeal diseases.
• To evaluate the diagnostic significance of Electroglottographic waveform characteristics.
• To establish EGG as a quantitative and objective tool for laryngeal disease diagnosis.

Summary:

• Electroglottography (EGG) was performed on 237 patients with laryngeal diseases (vocal polyp, nodule, paralysis, cancer, Reinke's edema) using the Dr. Speech science for Windows program.
• Abnormal EGG waveform changes were observed and found to correlate with the type, position, and size of the laryngeal disease.
• The study demonstrates that EGG waveform alterations provide a quantitative and objective index for diagnosing laryngeal diseases.

Impact:

• Electroglottography offers a non-invasive method for assessing laryngeal function.
• The findings support the integration of EGG analysis into routine clinical practice for laryngeal disease diagnosis.
• This objective data can aid clinicians in differentiating between various laryngeal pathologies and guiding treatment strategies.
