Head-to-Head Analysis of Vertical vs Horizontal Incision Patterns in Breast Reconstruction: Surgical Outcomes and Aesthetic Implications.

Background: Modern aesthetically optimized breast reconstruction requires collaboration between the patient, breast surgeon, and plastic surgeon. To optimize both surgical outcome and aesthetic results, incision patterns must be carefully planned.

Objectives: We aimed to determine whether vertical or horizontal orientation of mastectomy incision was preferred in the general population and to analyze corresponding complication profiles.

Methods: A retrospective review was performed of all patients undergoing bilateral mastectomy followed by autologous breast reconstruction utilizing either vertical or horizontal incision from January 2011 to November 2022. Postoperative complications of the 2 incision patterns were analyzed. Additionally, crowdsourcing was utilized to assess aesthetic implications of horizontal and vertical incision patterns on postoperative pictures of completed breast reconstruction. Survey rater demographics were also analyzed to assess differences in scoring based on voter characteristics.

Results: There were no significant differences in postoperative breast complications between patients with horizontal or vertical incisions when considering wound, infection, seroma, hematoma, fat necrosis, or overall complications (P > .05). Crowdsourcing showed that, regardless of voter demographics, vertical incisions were preferred over horizontal incisions (P < .001). Additionally, voters who knew someone who had undergone breast reconstruction were more likely to rate all incision patterns higher than other voters (P < .001).

Conclusions: Although there are no significant differences in complication profiles between vertical and horizontal incisions in autologous breast reconstruction patients, vertical incision patterns are preferred aesthetically by the general population.
