“…Others have published on the Sommerlad soft palate repair technique (Andrades et al, 2008; Becker & Hansson, 2013; Doucet et al, 2013; Luyten et al, 2013; 2014; Yang et al, 2013; Cairns et al, 2014; Moar et al, 2016; Rossell-Perry et al, 2015; Dissaux et al, 2016; Nyberg et al, 2018; Bruneel et al, 2018; Klinto et al, 2018; Mapar et al, 2019; Smyth & Wu, 2019). In 3 studies, the Sommerlad intravelar veloplasty was part of a protocol of delayed hard palate closure (Doucet et al, 2013; Dissaux et al, 2016; Klinto et al, 2018 [in 2 of 3 centers]); in another 2 studies, gold standard speech methodology was not used (Andrades et al, 2008; Yang et al, 2013); in 3 studies detailed speech results were not given (Becker & Hansson, 2013; Rossell-Perry et al, 2015; Moar et al, 2016). The Luyten et al (2014) study is subject to bias due to different surgeons in different countries and different languages of the speech and language therapists and participants (Hutters & Henningsson, 2004).…”
