ABSTRACT
BACKGROUND:
Incision planning is a critical factor in nipple-sparing mastectomy outcomes. Evidence on optimal incision patterns in patients undergoing nipple-sparing mastectomy and immediate microvascular breast reconstruction is lacking in the literature.METHODS:
A single-institution retrospective review was performed of consecutive patients undergoing nipple-sparing mastectomy and immediate microvascular autologous reconstruction from 2007 to 2019. Outcomes-including major mastectomy flap necrosis, full nipple-areola complex necrosis, and any major ischemic complication of the skin envelope-were compared among incision types. Multivariable logistic regression identified factors associated with major ischemic complication.RESULTS:
Two hundred seventy-nine reconstructions (163 patients) were identified, primarily using internal mammary recipient vessels (98.9 percent). Vertical incisions were used in 139 cases; inframammary, in 53; lateral radial, in 51; and inverted-T, in 35. Thirty-two cases (11.5 percent) had major mastectomy flap necrosis, 11 (3.9 percent) had full nipple-areola complex necrosis, and 38 (13.6 percent) had any major ischemic complication. Inframammary incisions had higher rates of major ischemic complication (25 percent) than vertical (5.8 percent; p < 0.001) and lateral radial (7.8 percent; p = 0.032) incisions. Inverted-T incisions also had higher rates of major ischemic complication (36.1 percent) than both vertical (p < 0.001) and lateral radial (p = 0.002) incisions. Inframammary incisions (OR, 4.382; p = 0.002), inverted-T incisions (OR, 3.952; p = 0.011), and mastectomy weight (OR, 1.003; p < 0.001) were independently associated with an increased risk of major ischemic complication. Inframammary incisions with major ischemic complication demonstrated significantly higher body mass index, mastectomy weight, and flap weight compared to those without.CONCLUSIONS:
Inframammary and inverted-T incisions are associated with a higher risk of major ischemic skin envelope complications after nipple-sparing mastectomy and immediate microvascular breast reconstruction. Radial incisions can be considered to optimize recipient vessel exposure without compromising perfusion. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.
