ABSTRACT
Objective To analyze the medical and audiological features of trauma induced stapes fracture ,and to summarize the key diagnostic points and to observe the effects of surgical treatment .Methods Five patients with trauma induced stapes fracture confirmed by the surgical exploration from January 1995 to October 2013 were retro_spectively reviewed .Ossicular chain reconstruction was performed on each patient .The preoperative and postopera_tive pure-tone thresholds were compared to judge the effects of surgical treatment .ResuIts The surgical explora_tion revealed 4 cases of stapes feet fracture ,1 case of stapes neck fracture with temporal bone fracture and peripheral paralysis of the facial nerve .Different types of ossicular reconstruction were performed according to the exploration results:2 cases with autogenous stapes remodeling ,1 case with allogenous stapes remodeling ,1 case with bone piece of external acoustic meatus ,and 1 case with artificial auditory ossicle(TORP) implanting .Additionally ,the case of peripheral paralysis of the facial nerve received facial nerve decompression .After the operation ,5 patients felt that their hearing was improved .The mean postoperative pure-tone threshold was 30 .7 dB HL ,and the mean ABG(air-bone-gap) was 18 dB HL while the mean preoperative pure-tone threshold was 61 dB HL(t=6 .725 ,P<0 .05) and the mean ABG was 38 .7 dB HL(t=3 .616 ,P<0 .05) .The facial nerve functions of the case with facial paralysis recovered to House-Brackmann Grade I three months after receiving facial nerve decompression .ConcIu_sion Stapes fractures are rare .Being different from the general conductive hearing loss ,patients with stapes fracture usu_ally have the acoustic stapedius reflex .Through ossicular reconstruction ,we can yield a satisfying hearing recovery .
