Experiencing dimpling, bumpy lumps, or irregularities a year after thigh lift surgery can be concerning and may indicate several potential issues. It's essential to consult with your plastic surgeon to determine the cause and appropriate treatment. Here are some possible reasons for these symptoms: 1. Scar tissue formation: After surgery, the body naturally forms scar tissue as part of the healing process. In some cases, this scar tissue can cause irregularities or bumps in the skin's appearance. This is more common in areas where the skin was tightened or where there was significant tissue manipulation during the thigh lift procedure. 2. Seroma or hematoma: Fluid accumulation (seroma) or blood pooling (hematoma) under the skin can lead to lumps or bumps. While seromas and hematomas typically occur shortly after surgery, they can persist or develop later, especially if they were not adequately drained or resolved initially. 3. Fat necrosis: In some cases, fat cells may undergo necrosis (cell death) due to inadequate blood supply or trauma during surgery. This can lead to the formation of firm, irregular lumps or nodules under the skin. 4. Infection: Infections can cause inflammation and swelling, leading to the formation of lumps or bumps in the affected area. While infections are more common shortly after surgery, they can occur later if bacteria enter the surgical site. 5. Tissue laxity or recurrence of laxity: Thigh lift surgery aims to remove excess skin and tighten the remaining tissue. However, over time, the skin and underlying tissues may lose elasticity, leading to the recurrence of laxity or the development of new sagging. 6. Poor wound healing: Factors such as smoking, diabetes, poor nutrition, or other medical conditions can impair wound healing and increase the risk of complications such as irregular scarring or tissue irregularities. It's crucial to have a thorough evaluation by your plastic surgeon to determine the cause of the dimpling, bumpy lumps, or irregularities after thigh lift surgery. Treatment options may include massage therapy, scar management techniques, revision surgery, or other interventions depending on the underlying cause.
