Hi, thank you for your question regarding the thigh lift and thigh reduction as well as the posterior body lift to include the low back and buttock lift. Congratulations on your significant weight loss history! The posterior body lift includes an incision that extends from the hip, to the top of the buttock crack, and to the other or contra-lateral hip. It basically joins the tummy tuck or abdominoplasty incisions across the back. This procedure takes me approximately 4 hours under general anesthesia to complete and requires approximately about a 2 week recovery. Your post-operative position for the posterior back lift surgery should be a straight back. Most patients prefer to be flat on their back without the head of the bed being elevated. After a posterior body lift, sitting in a chair is not suggested as this puts too much strain on the lower back. After approximately 3 to 4 weeks, you are allowed to sit at a 45 degree angle and at approximately 6 to 8 weeks, you are allowed to sit at a 90 degree angle. Often, I combine the posterior body lift or circumferential lower body lift with the medial thigh lift or thigh reduction. During a thigh reduction, I perform thigh liposuction and usually make an incision from the groin to the knee. After liposuction, an inner thigh incision is made and a large elliptical area of inner thigh skin and fat from the groin to the knee is removed. This procedure takes me approximately 4 hours to complete under general anesthesia. Because of the nature of the incision and the high risk of blood clots, I have you in a monitored unit for 48 hours after the posterior body lift and thigh reduction surgery. You will also be placed on blood thinners for 2 weeks. Ideally, after your thigh lift or thigh reduction, your thighs should be straight at the hips and knees with your ankles above your heart. If you combined the posterior body lift with the thigh lift, you do not want the hips bent or the knees flexed as this puts undue stress on the lower back incision. Therefore, your recovery position should be flat on your back with your legs straight. You can be flat on your back or straight on your abdomen. The recovery from a medial thigh lift is approximately 2 weeks. If you combine the posterior body lift and the medial thigh lift, the recovery time is approximately 2-3 weeks. If you have a standing job, you should be able to return to work 3-4 weeks after surgery. If you have a sitting job, please plan to return at approximately 4-6 weeks. You should be able to perform activities of daily living at approximately 2-3 weeks. However, bending at the waist will be significantly limited for 4-6 weeks. I would also suggest you avoid stairs for approximately 3-4 weeks as this puts undue pressure on the medial thigh incision. You should be in a compression garment for a minimum 6 weeks. If you continue to have swelling after 6 weeks after your posterior body lift and medial thigh lift, you may need to continue to wear your compression garment for an extended period of time. I hope you find this information useful and I wish you luck on your upcoming surgery.
