Abstract
PurposeTo review delayed-onset skin flap complications associated with pediatric cochlear implantation (CI) in our institute, analyze the etiology, and explore effective treatment strategies.MethodsRetrospective analyses of 811 children who had undergone cochlear implantation between January 2003 and March 2019 were performed. Twelve (1.48%) patients developed skin flap complications after CI. We present a classification of flap issues and wound histopathology following cochlear implantation. The interventions for flap problems included drug treatment, aspiration, local wound care, revision surgery, and explantation depending on the clinical situation. The temporalis myofascial reconstructive option is discussed.ResultsSeven subjects were cured with conservative treatment. Five cases with flap infection or necrosis underwent revision surgery, with wound closure in three cases (60%) and revision surgery with explantation in the remaining two cases (40%). Explantation ultimately led to wound healing in all cases. They all achieved excellent performance through re-implantation.ConclusionFlap complications after CI are rare but treatable. Comprehensive treatments should be developed to achieve a stable and healed wound for CI.

Summary
Cochlear implantation (CI) is the most effective technique for treatment of bilateral severe to profound sensorineural hearing loss. Since the 1960 s, almost 1 million patients have benefited from CI, and it is generally a safe procedure in experienced hands. As with all surgical procedures, there are complications associated with CI. The complications depend on patient condition, the type of implant device, and the surgical technique. Skin flap issues are the most common complications associated with CI. The frequency of skin flap complications reported in the
