OBJECTIVE: Cornelia de Lange syndrome (CdLS) is a multiple developmental disorder including hearing loss. The hearing impairment in CdLS patients is not only sensorineural but also conductive hearing loss (CHL). The aim of this study was to elucidate hearing loss causes in CdLS patients and evaluate the effect of ventilation tube (v-tube) insertion in the cases of CHL.
METHODS: Thirty-two patients clinically diagnosed with CdLS were enrolled and analyzed with retrospective case review. Audiologic evaluations and imaging studies such as a temporal bone computed tomogram or brain magnetic resonance imaging (MRI) were performed for all patients. Hearing rehabilitation such as ventilation tube insertion, hearing aid fitting, or cochlear implantation was chosen depending on the audiological condition.
RESULTS: Among 32 CdLS patients who underwent auditory brainstem response test, 81.2% presented hearing loss. Imaging studies showed that only middle ear lesions without inner ear anomalies were identified in 56.3%. Notably, the soft tissue lesion in middle ear was identified even in the neonatal MRI. When 7 patients were thought to have CHL due to otitis media with effusion, v-tube insertion was applied first. However, v-tube insertion rarely improved CHL postoperatively. Moreover, middle ear lesion was not fluid effusion but soft tissue lesion according to the intraoperative finding. These lesions were not eradicated even after revision surgery of v-tube insertion.
CONCLUSION: V-tube insertion is not effective to improve hearing or eradicate otitis media with effusion in CdLS patients.
