Objectives: (1) Estimate the degree of postoperative aeration in middle ear after canal wall down tympanoplasty with soft‐wall reconstruction (CWD SWR) for cholesteatoma. (2) Characterize relationship between and hearing outcome. (3) Propose an ideal state order to obtain satisfactory outcome CWD SWR. Methods: This retrospective study was conducted our tertiary referral hospital 2001 2013. Seventy‐eight ears cholesteatoma treated surgically at by planned two‐stage SWR were included. Postoperative scored one year second‐stage surgery computed tomography (CT). The patients divided into 4 bins according audiometric air‐bone (A‐B) gaps: 0‐10, 11‐20, 21‐30, >30 dB. Results: significantly greater smaller A‐B gap (0‐10 11‐20 dB) compared larger (21‐30 dB). In contrast bins, those gaps showed reaeration antrum mastoid cavity. Conclusions: Promoting entire is necessary achieve better undergoing ventilation tube insertion placement large silicone sheet from protympanum cavity first‐stage are candidate procedures promote aeration.
