Several resorbable fixation systems are used for osteosynthesis in craniofacial surgery. Recently, ultrasonic-assisted pinned resorbable systems have been introduced; however, few studies have described the associated complications during the long-term follow-up until complete resorption. In this study, we investigated the complications of craniofacial surgery using the ultrasonic-assisted pinned resorbable system with a follow-up of at least 30 months. Among patients who underwent craniofacial surgery using a commercially available ultrasonic-assisted pinned resorbable system between 2014 and 2016, those with follow-up visits for at least 30 months were included in this study. We investigated the development of complications such as local infection, exposure of the device, and reoperation related to the implant. Twenty-four patients aged 6 months to 69.4 years (median: 3.5 years) were followed up for more than 30 months. None of the patients required reoperation regardless of implants. Further, no infection or device exposure was seen among all patients. However, two patients aged 6 and 22 months who underwent cranioplasty for craniosynostosis and another patient aged 148 months who underwent cranioplasty for cranial defect exhibited plate-related bulging in the scalp during the course of resorption between 7 and 12 months of follow-up. The bulges were characterized by swelling without pain or redness and resolved spontaneously within 18 months of follow-up, which was considered to occur after complete absorption of the plate. In conclusion, subcutaneous swelling is related to resorbable plates and has a benign clinical course. We recommend that patients be informed of this phenomenon preoperatively to relieve their anxiety.
