    Palate repair in children with cleft palate improves Eustachian tube function. Repaired palates allow for better middle ear pressure equalization, suggesting increased tubal stiffness and reduced obstruction.

    Area of Science:

    • Otolaryngology
    • Pediatric Surgery
    • Speech and Hearing Science

    Background:

    • Cleft palate significantly impacts Eustachian tube (ET) function.
    • ET dysfunction can lead to middle ear pathologies in children with cleft palate.

    Purpose of the Study:

    • To assess the ventilatory function of the Eustachian tube in infants and children with cleft palate.
    • To evaluate the impact of palatal repair on Eustachian tube function.

    Main Methods:

    • Assessment of Eustachian tube ventilatory function.
    • Comparison of pressure equalization abilities between children with open clefts and those who underwent palatal repair.
    • Evaluation of Eustachian tube function in repaired cleft palate patients against normal subjects.

    Main Results:

    • Children with repaired palates demonstrated improved ability to equilibrate applied positive middle ear pressures compared to those with open clefts.
    • Eustachian tube function in many repaired cleft palate patients approached that of normal subjects.
    • Differences in function are attributed to variations in tubal compliance.

    Conclusions:

    • Palatal repair positively influences Eustachian tube ventilatory function in children with cleft palate.
    • Improved function post-repair is likely due to increased tubal stiffness, reducing obstruction.
    • Excessive tubal compliance may cause or worsen functional Eustachian tube obstruction.
