Q78 What is the maximum that can be transplanted in one session?
Conclusion
The limit per session depends jointly on safe donor extraction, surgery duration and the time grafts spend outside the body. We do not promote a fixed maximum unit count.
Supporting information
All operations.
Longer time outside the body worsens graft survival conditions. A published non-shaven series reported a daily limit of around 3,000 units: Park JH, You SH, Kim NR. Ann Plast Surg. 2019;82(3):262–268. DOI: 10.1097/SAP.0000000000001679 (658 cases).
Risks and limitations
Attempting excessive transplantation in one session increases both overharvesting risk and risks to graft survival. Extensive needs usually require staged procedures.
Next steps
Ask the doctor to explain the specific factors limiting your session.
