“…Pendred syndrome, the most common syndromic cause of SNHL, is another syndromic condition that is inherited in an autosomal recessive fashion and usually causes congenital SNHL, often at birth, via enlarged vestibular aqueduct, a common inner ear deformity (Smith et al, 2005;Morton and Nance, 2006;Azaiez et al, 2007;Wémeau and Kopp, 2017). Studies of cochlear implantation in children with Pendred syndrome found that they have better speech perception compared to children who are deaf due to enlarged vestibular aqueduct not caused by Pendred syndrome despite the possibility of mild surgical complications due to the inner ear malformations caused by Pendred (Kontorinis et al, 2011;van Nierop et al, 2016;Mikkelsen et al, 2019;Mey et al, 2020). Other studies indicate that early diagnosis of SNHL, followed by cochlear implantation and rehabilitation, is also beneficial in Usher and Waardenburg Syndromes (Young et al, 1995;Loundon et al, 2003;Cullen et al, 2006;Hartel et al, 2017;Alzhrani et al, 2018;Nair et al, 2020).…”
