Event Description

The patient/complainant reported receiving several facial implants, then subsequently experienced the stitches at site of left side mandibular implant opening with an outflow of fulid and blood (approximately 5 days post-op).Seven (7) days post-op, the doctor sewed up the incision site.Four (4) weeks post-op, the stitches had reopened, and were again sewed up under local anesthesia.Five (5) weeks post-op, the doctor sewed up the incision for the third time because they had again reopened.Almost 7 weeks postop, patient reported to physician that the stitches had opened more than ever and the implant was visible.Approximately eight (8) weeks post-op, patient had a second operation under total anesthesia, where the doctor "removed the implant, reconstructed the area, sterilized the implant clinically himself and placed it again, placing 1 screw intraorally".Three (3) months after the second surgery, the post-operative swwelling had not subsided.The patient had lost faith in the original doctor, and saw another physician who suggested a possible infection.Patient saw another doctor who diagnosed asymmetry in the face with severe swelling on the left side.The doctor prescribed an antibiotic (dalicin) to treat the infection.While taking the antibiotic, a slight reduction in swelling was observed, but after the course of antibiotics, the swelling returned and the physician recommended he visit another doctor.The device was explanted due to left side infection approximately 14 months post-op.A culture was taken and staphylococcus epidermidis was identified.
