Implantation dermoid cyst post cochlear implantation: an unusual complication

Epidermal inclusion cysts are benign epithelial tumours that can occur in any part of the body. It can be primary or secondary to trauma or surgery that leads to the implantation of the epidermal elements into dermis and subcutaneous tissue forming a benign cyst. There is paucity of literature reporting postauricular epidermal inclusion cysts following a cochlear implant surgery with the functioning implant in situ. We are reporting such a case of postauricular implantation dermoid following cochlear implant surgery, which was successfully managed surgically at our centre without compromising the functioning cochlear implant.
