Abstract

Background
Following primary cleft palate repair, individuals face a heightened risk of hearing problems, particularly conductive hearing loss, compensatory articulation disorders (CADs), resonance disorders, delayed speech and language development, and voice disorders. This study aimed to investigate the prevalence and impact of these challenges in children with cleft palate with or without cleft lip (CP± L).
Methods
This cross-sectional study included 38 children with CP± L aged 5 to 13 years. A comprehensive evaluation involved audiological assessments (audiograms, tympanograms) by an audiologist and speech-language pathology assessments (Thai Speech Parameters for Patients with Cleft Palate, Articulation Screening Test) by speech-language pathologists.
Results
The prevalence of hearing loss affected 27.63% of participants (21 out of 76 ears) and majority of cases involved conductive hearing loss. Velar substitution was the most common CAD, followed by nasalized voiced pressure consonants, phoneme-specific nasal air emission, and pharyngeal substitution. A moderate correlation was found between these CAD patterns and hypernasality at the word, sentence, and screening levels (r= 0.44, p< 0.01; r= 0.43, p< 0.01; and r= 0.40, p= 0.01).
Conclusion
For summary, the most common type of hearing loss was conductive hearing loss. The predominant CAD pattern was velar substitution. The protocol could be designed to enhance early improvement in hearing and articulation, thereby supporting academic achievement and long-term quality of life.
