OBJECTIVE: To investigate the diagnose therapy and the postoperative curative effect of traumatic ossicular chain disruption and dislocation.
METHOD: Eight cases (8 ears) with traumatic ossicular chain disruption. Six cases of unilateral conductivity deafness, 2 of mixed deafness still with conductive primarily. Eight ears all were performed tympanic exploration and ossicular replacement prosthesis, 1 ear with TORP (total ossicular replacement prosthesis). 4 ears with PORP (partial ossicular replacement prosthesis), 2 with ossicular chain reset, 1 with artificial incus reconstruction. The treatment effect was compared by the preoperative and postoperative ABG (air bone gap).
RESULT: Preoperative average ABG was 42. 9 dB, the average ABG 3 weeks after operation was 22.3 dB, which reduced 20.6 dB compared to the preoperative, having a statistically significant difference (t = 22.10, P < 0.01). The average ABG was 18.6 dB 6-8 months after operation, which reduced 24.3 dB compared to the preoperative, having a statistically significant difference (t = 12.813, P < 0.01).
CONCLUSION: The conductivity hearing loss after traumatic ossicular chain disruption or dislocation is preferred operation treatment, and replacement should use different ways according to the operation in case, and the hearing improvement was obvious.
