چکیده (انگلیسی):

Background: The round block technique (RBT) is an oncoplastic technique in which
only the perimamillary scars remain visible. We have performed RBT in cases that require
resection of the breast tissue under the nippleeareola complex (NAC) and a modified round
block technique (MRBT) in peripheral cases in which performing resection of the breast tissue
under the NAC is unnecessary. We herein report the usefulness of these techniques.
Methods: The study participants consisted of 18 patients who underwent breast-conserving
surgery (BCS) using MRBT or RBT between July 2010 and July 2011. In the cases using RBT,
de-epithelialization between the outer and inner incision lines was performed and the dermis
was cut at the side of the tumor location. For MRBT cases, the dermis was cut in all parts of the
inner and outer circles, and the skin between the inner and outer incision lines was resected.
Results: Cosmetic results were found to be excellent in three cases, good in eight cases, fair in
five cases, and poor in two cases. In this study, the cosmetic results were unacceptable (fair
and poor) in patients who underwent
25% resection or in whom the resected area was part
of the lower portion of the breast.
Conclusion: These techniques are useful for performing BCS in the upper portion of the breast.
However, if the excision volume is >20% or excision of part of the lower portion of the breast is
required, other procedures should be considered.
