Pathologic Processes in the Larynx Leading to a Change in the Voice Function

Area of Science:

• Laryngology
• Phonetics
• Voice Science

Background:

• The larynx is a vocal organ crucial for phonation, producing sound through vocal cord vibration.
• Pathologic processes affecting the larynx can significantly alter voice function.
• Understanding these pathologies is essential for diagnosing and managing voice disorders.

Purpose of the Study:

• To systematically review the literature on common laryngeal pathologies impacting voice function.
• To identify the most frequent causes and symptoms of voice changes due to laryngeal disorders.

Main Methods:

• A systematic literature analysis was performed using major scientific databases (PubMed, Scopus, Web of Science, Embase, etc.).
• Publications from January 2000 to September 2024 were reviewed.
• The focus was on studies investigating laryngeal pathologies and their effect on voice function.

Main Results:

• Laryngeal pathologies are common, stemming from diverse factors including inflammation, trauma, and oncological diseases.
• Frequently observed symptoms include hoarseness, voice changes, dysphonia, aphonia, and pain.
• Clinicians need awareness of these symptoms for effective patient care.

Conclusions:

• Laryngeal pathology is prevalent, influenced by environmental factors like allergens and carcinogens.
• Impaired voice quality significantly reduces patients' quality of life.
• Laryngeal oncological diseases can impact overall life expectancy.
