Summary
Assessing speech in patients with craniofacial anomalies is crucial for treatment. The Dynamic Dento-palatography System shows improved speech sound quality post-surgery.
Area of Science:
- Speech pathology
- Biomedical engineering
- Craniofacial surgery
Background:
- Effective treatment for craniofacial anomalies requires assessing oropharyngeal function, particularly speech.
- Optimizing speech is a key goal in managing patients with craniofacial conditions.
Purpose of the Study:
- To describe the Dynamic Dento-palatography System for analyzing speech in patients with craniofacial anomalies.
- To present preliminary results on the system's effectiveness in evaluating articulatory, auditory, and acoustic speech components.
Main Methods:
- Utilized the Dynamic Dento-palatography System, featuring multi-electrode array sensors.
- Monitored tongue position during articulation to analyze speech production.
- Integrated analysis across articulatory, auditory, and acoustic speech levels.
Main Results:
- Preliminary data indicate improvements in speech sound quality after surgical intervention.
- Specific improvements noted in the production of sounds like 's' and 't'.
- The system demonstrated potential for detailed speech analysis in this patient group.
Conclusions:
- The Dynamic Dento-palatography System is a valuable tool for assessing speech in craniofacial anomaly patients.
- Post-operative speech sound quality, particularly for sibilants and stops, shows enhancement.
- Integrated analysis of speech components aids in understanding and optimizing oropharyngeal function.
