“…RAOM is diagnosed in children with ≥3 OM episodes in 6 months or ≥4 in 12 months, and COME if ME effusion behind the intact eardrum persists for >2 months ( Rosenfeld et al, 2016 ). Combined, these OM types and surgery are associated with 4–11× risk of permanent HL ( Rach et al, 1988 ; Beyea et al, 1999 ). RAOM/COME cause defects in language ability, auditory perception, sound localization and auditory processing in 5–11% of school-age children, which impedes academic progress ( Morrongiello, 1989 ; Zargi and Boltezar, 1992 ; Moore, 2007 ; Hind et al, 2011 ; Skarzynski et al, 2015 ; Graydon et al, 2017 ; Cordeiro et al, 2018 ; Leach et al, 2020 ).…”
