OBJECTIVE: To review long-term outcomes for chronic otitis media with and without cholesteatoma in staged canal-wall-up tympanoplasty with temporary silastic sheeting and to compare hearing and recurrence results with the literature.
METHODS: Retrospective data analysis of all patients suffering from chronic otitis media with or without cholesteatoma (COMC/COM) and treated by staged canal-wall-up (CWU) technique with silastic insertion between 1992 and 2012. Literature analysis in PubMed 1990-2017.
RESULTS: 74 cases were included in the analysis. In COMC (n = 47) a total of 2 (4%) recurrent and 14 (30%) residual cholesteatoma were documented. The postoperative hearing test showed a pure-tone-average (PTA) of 36 dB hearing level (HL) and an air-bone-gap (ABG) of 21 dB HL. A significant improvement was only observed for stage I disease (PTA 8 dB HL and ABG 9 dB HL). In COM (n = 27) postoperative PTA and ABG were significantly improved by 33 dB HL and 23 dB HL, respectively. Mean postoperative follow-up was 47 months (12-173) for COMC and 22 months (2-120) for COM.
CONCLUSIONS: The cholesteatoma recurrence rate in this study reflects contemporary published rates. Assessment of hearing outcome is difficult due to the low number of cases and very high heterogeneity of published data. Still, the staged CWU procedure with temporary silastic sheeting seems to bear some advantages in regard to hearing. The role of additional factors such as Eustachian Tube function to assess outcome should be considered. An internationally agreed upon reporting system should be followed, if various surgical approaches are to be compared.
LEVEL OF EVIDENCE: 3.
