Hi, Pouch Lover. As other physicians have also answered, there is a risk of damage to the lymph nodes during a brachialplasty, bur fortunately that risk is not high when performed by a surgeon familiar in the anatomy of the area and experienced in the technique. A standard or limited arm lift, that is confined to the upper arm only and not the axilla, carries the least risk. As the brachialplasty is extended into the armpit, the risk is certainly higher (but still small). There may be disruption to the tiny lymphatic channels that carry the lymph from your arm up to the lymph nodes, or there may be compression to the lymphatic channels due to swelling, garment binding, poor positioning, etc. Such lymphatic channel disruption or compression may result in enhanced and/or persistent swelling. Post-operative elevation, massage, attention to proper garment fit and arm positioning may help reduce this potential issue.Good luck should you decide to pursue an arm lift, and I hope you have the results you are looking for and an uneventful recovery!
