After cochlear implantation: Complications related to flap around implants

OBJECTIVE: To report complications related to flap around implants after cochlear implantation, possible causes of such complications and treatments. METHODS AND MATERIAL: We performed a retrospective analysis of children in whom complications related to flap around implants occurred after undergoing cochlear implantation in our department from 2005 to 2016. RESULTS: Complications among 1500 cochlear implantation (CI) recipients by the same surgeon included hematoma (n = 20) and seroma around implants (n = 15), of which most (n = 10) recovered in 2 weeks after effective drainage, utility of antibiotics and pressure dressing, but 5 developed flap necrosis and had to undergo contralateral re-implantation. Four patients developed abscess around implants, of whom 2 recovered after 2 weeks of drainage, gentamicin irrigation and use of antibiotics, but 2 patients ended up with flap necrosis and had to receive contralateral reimplantation. CONCLUSIONS: Immediate drainage, pressure dressing and antibiotics can be used to effectively control seroma around implants. For seroma lasting for more than two weeks without improvement, surgical drainage may be need.
