Foreign substance injection for esthetic purposes associated with delayed unilateral sciatic nerve impairment: A surgical case report.

ABSTRACT

Attempts at body contour modifications have led to the use of different alloplastic materials that can irreversibly damage health and risk patients' lives. These modeling substances can induce a general autoimmune inflammatory response, producing a very heterogeneous clinical spectrum ranging from mild and severe systemic to local symptoms that sometimes affect peripheral nerves. We report a unique case of a tumor-like sciatic nerve impairment produced months after the injection of a modeling substance into the buttocks for esthetic purposes. The patient was treated with a surgical decompression of the sciatic nerve that encompassed the removal of the injected mass. This approach ultimately yielded a complete neurological recovery of the affected nerve. We emphasize the diagnostic approach and surgical management employed in this unique case and review the current literature on this infrequent complication.
