Aim: To longitudinally investigate speech production (consonant proficiency, consonant errors and perceived velopharyngeal competence) in 17 internationally adopted (IA) children with unilateral cleft lip and palate (UCLP) at three time points.

Method: Consonant proficiency (percent consonants correct, consonant inventory) and number and type of consonant errors were calculated based on blind phonetic transcriptions of words from the Swedish Test of Articulation and Nasality (SVANTE). Velopharyngeal competence was perceptually rated by three blinded experienced speech-language pathologists at the ages of 3, 5 and 7-8 years.

Background: It is anticipated that in due course the burden of emergency care due to COVID-19 infected patients will reduce sufficiently to permit elective surgical procedures to recommence. Prioritizing cleft/craniofacial surgery in the already overloaded medical system will then become an issue. The European Cleft Palate Craniofacial Association, together with the European Cleft and Craniofacial Initiative for Equality in Care, performed a brief survey to capture a current snapshot during a rapidly evolving pandemic.
