Joseph H. Dayan, MD
Plastic & Reconstructive Surgeon
My Role at MSKWe post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

About Me
- Associate Attending Surgeon
I am a plastic surgeon who specializes in microsurgical reconstruction. This is a versatile skill that allows me to address a number of reconstruction challenges in people who have undergone surgery for breast cancer and head and neck cancers. My passion is to use surgical innovation and individualized care to help cancer survivors preserve or restore their relationship with their body.

A major part of my practice is breast reconstruction. I am skilled at a number of techniques that use a person’s own tissue. These include DIEP, GAP, and PAP flaps. More recently, I pioneered the DUG flap technique, enabling even more people to be treated in this manner.
Microsurgical tissue transfer is also useful for nerve reconstruction. For example, people with facial paralysis due to parotid cancer, acoustic neuroma, or Bell’s palsy and people with developmental facial paralysis can benefit. I serve as Director of the Facial Paralysis Program at MSK. I have extensive experience using the full spectrum of techniques for facial reanimation after facial paralysis. These include multiple nerve transfers, nerve grafts, and muscle transplants.
My research is focused on lymphedema, and I serve as Co-Director of Lymphatic Surgery and Research at MSK. I am recognized as an international expert in lymphedema, serving as president and co-founder of the American Society for Lymphatic Surgery and as a board member of the Lymphatic Education and Research Network. I use both microsurgical and other techniques for the treatment of people with lymphedema and I have pioneered techniques to safely perform lymph node transplantation. I also use novel imaging studies to develop tailored treatment plans for each person I care for.
A plastic and reconstructive surgeon is a doctor with special training in cosmetic and reconstructive surgery. These procedures restore function and appearance.
