Abstract:
OBJECTIVE:To analyze the factors and biological characteristics of infection after cochlear implantation so as to control the risk factors and improve the treatment of postoperative infection.
METHOD:A retrospective study was conducted to analyze the clinical data of 316 patients receiving cochlear implantation from July 2001 to October 2011.
RESULT:Postoperative infection was found in five of the 316 cases and one transferred case. The six cases recovered after clinical therapy without explantation. One case underwent explantation due to recurrent meningitis after implantation of 8 years later.
CONCLUSION:The pathogens of infection after cochlear implantation are staphylococcus aureus, pseudomonas aeruginosa, etc. The key infectious factor is the formation of bacterial biofilm, which can be removal by chemical agents to control the postoperative infection, especially the flap infection. It is not necessary to remove the artificial cochlea when the postoperative infection occurs. Positive perioperative interventions and postoperative infection control can improve the outcome of cochlear implantation.
