Surgical Management of Post-Traumatic Breast Bisection Following Seat Belt Injury: A Series of Three Cases and Technique Description

Post-traumatic breast bisection secondary to seat belt injury is a rare and often unrecognized entity that may mimic breast cancer. It results from the formation of a transfixing fibrotic scar band responsible for a sharp linear deformity of the breast. Few cases have been reported in the literature, most often as isolated case reports. We report a single-center retrospective series of three patients who underwent surgical management in our institution for post-traumatic breast deformity following seat belt injury. Clinical, radiological, operative, histopathological and follow-up data were analyzed. All patients presented with a transfixing fibrotic band deformity associated with imaging-confirmed fat necrosis. The delay between trauma and surgical consultation ranged from 3 to 9 months. Surgical management consisted of bilateral reduction mammoplasty with complete excision of the fibrotic tissue. Glandular reconstruction relied on the use of a posterior glandular flap, combined with lipomodeling. Postoperative courses were uneventful. Follow-up exceeded 12 months for all patients, with stable and satisfactory aesthetic outcomes and no recurrence of deformity. Post-traumatic breast bisection must be recognized to avoid confusion with breast malignancy and to ensure appropriate management. Surgical treatment is based on excision of fibrotic tissue and glandular reshaping. The posterior glandular flap, combined when necessary with lipomodeling, represents a simple, reproducible, and effective technique, providing durable aesthetic results.
