Method: 71 ears of post-mastoidectomy (discharging 53 ears anddried up 18 ears) were undergone with reconstruction of middle ear. The posterior wall of external auditorycanal, mastoid cavity and chain of ossicles were reconstructed with homologous costal cartilage. Result: 69 ears of71 cases were near normal structure followed up 6 months to 5 years after operations. The result showed hearingimprovement over 15 dB were 55 ears (77.5％) and under 15 dB were 11 cases (15.5％). Five cases (7.0％)were failed. Conclusion: Reconstruction of middle ear with homologous costal cartilage is a ideal surgery toreconstruct hearing structure and avoid infection of middle cavity after radical mastoidectomy.
