    Summary

    Aerodynamic assessment helps evaluate prosthetic obturation effectiveness for speech. Successful obturation reduces respiratory effort by maintaining intraoral speech pressures in patients with surgical defects.

    Area of Science:

    • Speech-language pathology
    • Prosthodontics
    • Aerodynamics

    Background:

    • Assessing the seal between oral and nasal cavities is crucial for speech clarity after surgery.
    • Prosthetic obturation aims to restore this seal.
    • Understanding the impact of surgical defects on speech aerodynamics is essential.

    Purpose of the Study:

    • To evaluate the effectiveness of prosthetic obturation using aerodynamic assessment.
    • To quantify the impact of obturation on speech pressures and respiratory effort.
    • To understand patient responses to altered oral and pharyngeal structures.

    Main Methods:

    • Utilizing aerodynamic assessment, specifically the pressure-flow technique.
    • Measuring intraoral speech pressures during nonnasal consonant productions.

  • Quantifying respiratory effort in individuals with and without prosthetic obturation.

    • Main Results:

    • Individuals with large surgical defects exhibit increased respiratory effort to maintain speech pressures.
    • Successful prosthetic obturation effectively maintains intraoral speech pressures.
    • Obturation significantly reduces the respiratory effort required for speech production.

    Conclusions:

    • Aerodynamic assessment is a valuable, quantitative tool for evaluating prosthetic obturation.
    • Effective obturation improves speech aerodynamics by reducing respiratory workload.
    • This technique aids clinicians in managing speech outcomes post-surgery.
