Does Cleft Palate Repair Surgery Restore Normal Neural Processing for Infant Faces?

The current study used electroencephalography (EEG) to investigate adults processing of infant faces with cleft lip/palate before and after surgical repair. We found enhanced N170 responses for faces pre-repair surgery compared to post-repair surgery, suggesting that cleft lip/palate repair surgery may restore a more abnormal N170 response. Additionally, the P200 was smaller for the pre-repair surgery faces compared to post-repair surgery, which likely reflects the P200 responding to atypicality for face stimuli as the post-repair surgery faces would appear more face-typical.
