Introduction: Cochlear implantations have become a routinely performed and successful surgical intervention in both adults and children. The current article reports the complications encountered in the first 100 case of cochlear implantation at Zagazig university hospital. Also this article evaluate the relation of theses reported complication to the surgical technique, age of children, presence of co-morbidity, and the presence of inner ear anomalies.
Methods: We performed a prospective analysis of all cases that underwent cochlear implantation from October 2010 till June 2015 (100 case) at Zagazig university hospital. Two surgical techniques were used in our university, the classic approach used in 92 cases and the nonmastoidectomy approach used in 8 cases.
Results: The minor complications rate was 32%. The major complications rate was 8%. They were device failure in 3 cases, device extrusion in 3 cases, Facial nerve paralysis in one case, CSF otorhinorhea in one case. The incidence of complications was significantly more in non-mastoidectomy approach than classic approach. Also, the incidence of complications was significantly more in cases with comorbidity. But both the age of the patient and the presence of inner ear anomalies were not presenting a significant factor in the rate of the complications.
Conclusion: Cochlear implantation continues to be reliable and safe surgery. Rate of complications in our institute is comparable to the international recorded rates. Classic approach was safer than non-mastoidectomy approach.
