Objectives: Children with cleft palate may experience hearing problems, including middle ear disorders, which require careful monitoring to ensure successful treatment. To diagnose these hearing disorders, appropriate tools are necessary. While traditional single-frequency tympanometry has been commonly used as a practical tool for diagnosing middle ear problems, the effectiveness of this method has been questioned in some cases. Recently, newer tests of wideband tympanometry have been developed and may be able to provide a more comprehensive assessment of middle ear conditions in children with cleft palate.
Methods: To evaluate the effectiveness of wideband tympanometry, this study analyzed 14 young children who were scheduled to undergo cleft palate repair surgery. The children’s ages ranged from 4 to 24 months. The study involved two evaluations, one before the surgery and another one month after the surgery. Different wideband absorption parameters were analyzed using the paired t test and the Wilcoxon test.
Results: The analysis of statistical data regarding tympanometric parameters before and after cleft palate surgery indicated a general enhancement in the condition of the middle ear. The study found that the middle ear pressure decreased, the absorption percentage increased, and admittance increased across all five frequencies, which is consistent with our initial assumptions.
Discussion: The results confirm that wideband tympanometry can be an effective approach to detecting changes in the middle ear after cleft palate repair surgery in children. The use of more sophisticated parameters and evaluations at various frequencies provides a more complete picture of the child’s middle ear condition, potentially replacing single-frequency tympanometry assessments in the future.

• Middle ear disorders are so common in children with cleft palate.
• Wideband tympanometry shows promise as a valuable tool for monitoring middle ear function in children undergoing cleft palate surgery.
• Wideband tympanometry provides enhanced diagnostic capabilities compared to conventional methods.
Plain Language Summary
Middle ear wideband energy absorption changes were analyzed before and after cleft palate corrective surgery in children. Wideband tympanometry was used to assess 14 children aged 4 to 24 months pre and one-month post-surgery. Results showed improvements in middle ear pressure, absorption percentage, and admittance across all frequencies post-operation. This study indicates that wideband tympanometry is more effective than traditional single-frequency tympanometry in evaluating middle ear conditions after cleft palate surgery. The findings emphasize the significance of timely surgical intervention to enhance middle ear function in children with cleft and lip palate.
