My breast reduction wound has opened up 20 days post op while in Thailand for a vacation. What should I do? (Photo)

Thank you for your picture.  I am sorry for your issue.  I would contact your plastic surgeon.  If your plastic surgeon is in the United States I still would contact him or her for guidance.  They could give you wound care instructions.  It the situation becomes more serious you may need to seek medical attention from a plastic surgeon in Thailand

Sorry to hear of your predicament, however here are some thoughts: 1. you are already applying local wound care with  Fucidin; 2. limit physical activities such as swimming, zip-lining, etc; 3. be vigilant for extension of the wound dehiscence (separation) as well as signs and symptoms of infection (fever, purulent drainage, pain, etc.); 4. consult your PS, upon your return from vacation.  After breast reduction or lifts, the highest points of tension, which are most prone to separation are at the junction of the areola and at the inverted "T" junction.  Occasionally a suture remnant may initiate and prolong the inflammation.  Good luck!
