Summary
Functional voice disorders stem from vocal misuse. A classification and treatment approach showed excellent results for hysterical aphonia, habituated hoarseness, and falsetto voice, with good outcomes for vocal abuse and postoperative dysphonia.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Psychosomatic Medicine
Background:
- Functional voice disorders arise from vocal misuse or abuse.
- These disorders are identifiable by normal laryngeal structures despite voice quality aberrations.
- Prolonged functional dysphonia can lead to secondary laryngeal pathology.
Purpose of the Study:
- To present a classification system for functional voice disorders.
- To outline a diagnostic and treatment approach for these conditions.
- To evaluate the efficacy of the proposed approach in a clinical setting.
Main Methods:
- Classification of functional voice disorders into five types based on clinical experience.
- Diagnosis and treatment of 52 patients with these disorders.
- Follow-up of 48 patients for a median of 16 months to assess therapeutic outcomes.
Main Results:
- Five types identified: hysterical aphonia/dysphonia, habituated hoarseness, falsetto voice, vocal abuse, and postoperative dysphonia.
- Therapy achieved excellent results in 92% of patients (48/52) for types 1, 2, and 3.
- Good results were observed for types 4 and 5 functional voice disorders.
Conclusions:
- The proposed classification and treatment approach are effective for functional voice disorders.
- Early recognition and intervention are crucial for successful management.
- The study highlights the potential for significant voice improvement with appropriate therapy.
