This study provides a systematic review of the literature on nipple-sparing mastectomy and necrotic complications in order to estimate the prevalence of necrotic complications and to investigate their significant predictors. A literature search was conducted using the MEDLINE and Ovid databases. A pooled analysis was performed for calculation of the prevalence of nipple-areolar complex (NAC) necrosis, mastectomy flap necrosis, and overall necrotic complications and to evaluate the relationships between necrotic complications and potential risk factors. A total of 44 papers were analyzed. The prevalence of overall necrotic complications was 13.7%, including 7.5% for NAC necrosis and 7.8% for mastectomy flap necrosis. Types of incisions showed significant association with the rates of NAC necrosis and mastectomy flap necrosis. Incisions involving the NAC showed a significantly higher rate of NAC necrosis than those not involving it. The prevalence of NAC necrosis was higher in the autologous tissue reconstruction group than in the prosthesis group. Active smoking and diathermy dissection were significant predictors of both NAC necrosis and mastectomy flap necrosis. The findings of this review suggest that there are several predictors of necrotic complications in nipple-sparing mastectomy. Appropriate patient selection, careful operative planning, and surgical technique refinements may reduce the risk of necrotic complications. |
