    Summary
    This summary is machine-generated.

    This study details a novel hinge-type speech prosthesis for cleft palate repair. The prosthesis effectively restored clear speech, eliminating articulation errors and hypernasality.

    Area of Science:

    • Speech Pathology
    • Prosthodontics
    • Craniofacial Surgery

    Background:

    • Cleft palate significantly impacts speech clarity and resonance.
    • Existing speech prostheses can be cumbersome and require extensive adaptation.
    • Velopharyngeal insufficiency (VPI) is a common complication of cleft palate.

    Purpose of the Study:

    • To describe a novel hinge-type speech prosthesis.
    • To evaluate the functional outcomes of using this prosthesis in a patient with cleft palate.
    • To discuss the patient's adaptation and use of the prosthesis.

    Main Methods:

    • A custom-designed hinge-type speech prosthesis was fabricated.
    • The patient utilized the two halves of her native cleft velum to manipulate the prosthesis.

  • Speech function was assessed before and after prosthesis use.

    • Main Results:

    • The patient achieved speech free from articulation errors.
    • Audible nasal emission and hypernasality were eliminated with prosthesis use.
    • The patient successfully acquired the motor control to manipulate the velar section of the prosthesis.

    Conclusions:

    • The hinge-type speech prosthesis offers an effective solution for VPI in cleft palate patients.
    • Patient-specific adaptation and control are key to successful prosthesis function.
    • This innovative design facilitates improved speech intelligibility and quality of life.
