Effectiveness of ventilation tube insertion for conductive hearing loss in children with chronic otitis media with effusion and non-syndromic cleft palate: a systematic review protocol.

Abstract

This review will investigate the efficacy of ventilation tube insertion versus non-surgical options in the management of chronic otitis media with effusion in children with non-syndromic cleft palate by assessing the degree of conductive hearing loss. Chronic otitis media with effusion is common in children with cleft palate due to associated eustachian tube dysfunction. It can lead to impaired hearing and can hinder speech and language development. The main treatment options are drainage of effusion with ventilation tubes, surveillance, or amplification with hearing aids. Each of these approaches has its advantages but there is currently no consensus on the most appropriate management in children with cleft palate. Eligible studies will include children (<18 years) with cleft palate not associated with a genetic syndrome, diagnosed with chronic otitis media with effusion, who have undergone insertion of ventilation tubes compared with either surveillance or amplification with hearing aids. A comprehensive search of MEDLINE, CINAHL, Embase, and Scopus will be conducted to find published literature. Gray literature searches will be conducted through the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and ProQuest Dissertations and Theses Global. Two reviewers will screen studies, conduct critical appraisal of eligible studies, assess the methodological quality, and extract the data. Where possible, studies will be pooled in statistical meta-analysis, with heterogeneity of data being assessed using the standard χ 2 and I2 tests. PROSPERO CRD42021255861.
