Abstract
ABSTRACT Purpose: to describe the audiological profile of patients with Cornelia de Lange syndrome (CdLS) in an integrative review of the literature. Methods: after developing the research question, articles were searched in six databases (EMBASE, ISI of Knowledge, LILACS, MEDLINE/PubMed, SciELO, and Scopus) and in sources of information (Google Scholar, OpenGrey, and ProQuest), with the following descriptors: audiology, hearing loss, deafness, hearing disorders, and Cornelia de Lange syndrome. This review was registered in Prospero under number CRD42020191481. National and international studies were considered for analysis, using the PECO acronym. The risk of bias in the studies was analyzed with Joanna Briggs Institute protocols. Then, the studies were described and analyzed. Results: of the 1,080 articles found, 12 met the inclusion criteria. Audiological results showed that individuals with CdLS can have hearing loss - conductive hearing losses were the most frequent impairments, corresponding to 49.20% of individuals with CdLS assessed, followed by sensorineural hearing losses (13.49%). The degrees of hearing loss ranged from mild to profound. Conclusion: individuals presented with CdLS often have hearing loss, mainly due to middle ear changes, with degrees ranging from mild to profound.
