Abstract:
Objective To assessment the effect of autologous mastoid cortical bone to cover the mastoidetomy defect via transmastoid and posterior tympanotomy approach surgical technique during cochlear implantation in a ‐dults .Methods A total of 58 adults patients with profound sensorineural hearing loss accepted cochlear implantation from January 2010 and June 2014 ,which were using autologous mastoid cortical bone to cover the mastoidetomy de‐fect via transmastoid and posterior tympanotomy approach surgical technique .By observing postoperation complica‐tion the effect of surgery was evaluated .ABR were obtained for each patients at first ,third and sixth month after op‐eration .The patients which were not using autologous mastoid cortical bone to cover the mastoidetomy defect via transmastoid and posterior tympanotomy proach surgical technique acted as control group .Results No depression was found in the postauricuhtr site .None of the patients had experienced any immediate or delayed postoperative in ‐fection complication such as wound infection ,post - auricular abscess ,acute otitis media ,chronic otitis media ,in‐tracranial complication and necrotic of cortical bone .Autologous cortical bone cap had grew together with remnant cortical bone in all cochlear implantation patients .All implanted processor were in a good position ,all patients had good results after turning on the implant .The ABR thresholds were elevated about 70 dB compare to pre - operation values(P< 0 .05) .There was no significant difference compare to control group (P> 0 .05) .Conclusion The tech‐nique of autologous mastoid cortical bone to cover the mastoidetomy defect in cochlear implantation surgery can pre ‐vent depression of the postauricuhtr site ,remain stability of the implanted processor ,and have a good aided hearing thresholds after operation .
