OBJECTIVE: The objective of this study was to clarify the incidence and course of @entity393 after @entity4008 to optimize the audiological follow-up. DATA SOURCES: The databases Embase, Medline (OvidSP), Web-of-science, Scopus, Cinahl, Cochrane, PubMed publisher, and Google Scholar were used. Only articles written in English were included. STUDY SELECTION: Articles published from 1985 until March 2015 describing the incidence, risk factors, or course of @entity393 after @entity693 were used. DATA EXTRACTION: The quality of the studies was assessed on three aspects: quality of audiometry, number of @entity1 , and methodological quality. DATA SYNTHESIS: For each publication, data were entered in spreadsheet software for analysis. The data were analyzed and interpreted using best evidence synthesis. CONCLUSIONS: The overall quality of the included studies was poor. A major drawback was the quality of the (description of) audiometry, severity, and timing of @entity393 .A systematic review of the literature showed an incidence of @entity393 (>25  5dB) of 14% and an incidence of 5% for profound @entity393 (>90dB). @entity1 with initial normal hearing after @entity693 showed stable normal hearing over time. However, initial @entity393 related to @entity693 can improve or deteriorate over time.We therefore recommend early audiological testing of all @entity1 who suffered @entity4008 . However, long-term audiological follow-up is only needed for @entity1 with early onset @entity393 and not for @entity1 with normal hearing at the first hearing test.
