title: Late intracapsular seroma in subfascial buttock augmentation: a case report.
abstract: Late intracapsular seroma and hematoma have been described frequently as a complication of breast augmentation surgery. However, there are few reports of late intracapsular seroma in buttock augmentation. Textured and polyurethane implants have been used for subfascial enlargement of the buttocks. In this article, the authors report a large late intracapsular bilateral seroma caused by a retrofascial polyurethane-covered implant used for buttock augmentation: 1,200 ml on one side and 300 ml on the other. This patient's intracapsular seroma was of sudden onset 2 years and 6 months after surgery, and apparently had no relation to any trauma, use of medication, or physical exercise. Local tissues, including the gluteal fascia, were distended such that the implant was replaced inside the muscle and there was no relapse of the seroma. Late intracapsular hematomas or seromas from implants for buttock and breast augmentation may have the same etiology, and textured implants seem to be involved. All the reports on the matter are associated with textured implants. Any late seroma or hematoma caused by a smooth implant is related to an additional factor that may be considered as the etiologic agent. Further studies aimed at a large-scale assessment of the cause and actual incidence of late seromas and hematomas from textured implants are required.
