Breast volume replacement using the latissimus dorsi miniflap

Abstract

Background: Mastectomy is often recommended to women with early breast cancer who have large tumours or where the breast volume requiring resection to achieve adequate tumour clearance is too great to allow for a satisfactory cosmetic result after breast conservation surgery. The use of a latissimus dorsi muscular flap (latissimus dorsi miniflap (LDMF)) to replace the volume loss after major breast sector resection is an option where the tumour to breast volume ratio is large. The present study describes the technique and evaluates the experience of the LDMF at Royal Adelaide Hospital, Adelaide, Australia.

Methods: Between August 1997 and April 2002, 18 women aged 37-64 years underwent wide local excision for primary breast cancer with LDMF reconstruction. Tumour characteristics, breast specimen weight and postoperative sequelae were assessed. Quality of life measurements and objective assessments of aesthetic outcome were evaluated.

Results: Tumour diameter ranged from 13 to 80 mm (median 30 mm). Nine patients had multifocal or extensive intraductal component positive tumours. The weight of the resected specimens ranged from 75 to 395 g (median 130 g). There were no major postoperative complications, with a range of inpatient stay of 3-10 days. Seromas were aspirated in 14 patients but did not delay adjuvant treatment. Quality of Life results showed high patient satisfaction in all but one patient. A satisfactory cosmetic result was achieved in all but one patient who subsequently required mastectomy.

Conclusion: The LDMF procedure allows breast conservation to be achieved in women with large tumour to breast volume ratios, with satisfactory resection margins and good cosmetic and functional results. In the present experience standard oncological adjuvant treatment is not compromised.
