Purpose of the Study:
- To introduce a new, reliable method for detecting and quantifying nasal air emission during continuous speech.
- To demonstrate the clinical utility of this method in differentiating speech disorders.
- To highlight its role in patient selection for surgical interventions and speech therapy progress monitoring.
Main Methods:
- Utilized an electronic sensor placed near the nasal opening to detect airflow.
- Transduced nasal airflow into an electrical signal.
- Recorded and displayed the signal on a digital LED readout for charting and analysis.
Main Results:
- The developed method reliably detects and quantifies the degree of nasal air emission.
- The charted data allows for clear differentiation between various speech disorders.
- Clinical application proved the method to be quick and dependable.
Conclusions:
- This innovative nasal speech evaluation technique is vital for speech disorder rehabilitation.
- The device offers a valuable tool for speech therapists in assessment and progress tracking.
- It supports informed patient selection for corrective surgical procedures and therapy regimens.
