Recent Brachioplasty - 2 Wks Post Op. Small 1' Opening Still Not Healing Quickly...

It's not unusual for patients to have wound healing problems following arm lift surgery. The problem typically occurs where the vertical incision meets the transverse incision. This location is at risk for wound separation for a variety of reasons. These include poor blood supply to the skin flaps in this location and high levels of bacteria that occur in the axilla. Both of these factors can contribute significantly to wound breakdown in this area.Once breakdown has occurred, wounds tend to heal by secondary intention. Tissue tends to form a layer of granulation and wounds contract. The skin grows over the top of the granulation tissue. In the initial phases of healing, there may be an intense inflammatory response that can make the wound look red and angry.For these reasons, these wounds should be monitored closely. If infection appears, antibiotics should be started immediately. In the interim, local wound care should be continued with dressing changes. When this approach is taken, wounds tend to heal nicely. Rarely, scar revision may be necessary as a secondary procedure. If you have questions or concerns about how your wound is healing, it's important that you discuss them with your plastic surgeon. Your surgeon should be able to address your concerns and alleviate your anxiety.

Thank you for your question regarding a small opening after brachioplasty.
It is difficult to answer your question without pictures or a thorough physical examination. Though not common, brachioplasty incisions can open. The physical examination of the wound determines what topical treatments should be done. If your arm wound is open, please visit your plastic surgeon weekly for treatment.
Arm compression garments are essential after an arm lift or brachioplasty. The compression garments help to minimize swelling or edema. Though rare, permanent hand and forearm swelling can occur after a brachioplasty. Compression garments help to minimize this. The compression garment also helps to flatten the arm lift scar. This leads to a better cosmetic result.
Good luck with your skinnier arms.
If you have any questions, please do not hesitate to contact my office.

Unfortunately the arm pit is a difficult area to heal because of frequent motion and high normal bacterial counts, sweating, etc. Arm lifts therefore occasionally have problems like this, especially in the axilla (arm pit).
The most common reason would be absorbable sutures that are reactive and being pushed out  through the the skin but an infection could also be the cause.
The good news is that your arm lift will heal. It just needs more time.
See your board certified plastic surgeon to be checked.

I know this must be a concern for you, but it is unfortunately very common post armlift for patients to have openings occur. You should first consult your surgeon with this issue and they will give you proper instructions on how to take care of your opening in order to properly heal your wound.

When this occurs to my patients I will have them increase their protein levels and to make sure they are packing and doing dressing changes twice a day. Keeping the area clean is essential.

If for any reason the scar does not turn out favorably, you can have your surgeon perform a scar revision or you can consult with another board certified plastic surgeon about your revision. Whichever you prefer if it happens to occur.

Unfortunately it is not too uncommon to have some small areas with delayed healing after a brachioplasty. The skin quality in this area is unique. It will take several weeks to heal but it will heal well. A scar revision may or may not be necessary depending upon the result at 6 months to one year.
