Chronic Expanding Hematoma on Latissimus Dorsi Free Flap Donor Site Grown over 17 Years

Abstract

The latissimus dorsi free flap (LDFF), that provides long vascular pedicle with rich vascularization and adequate bulk for maxillofacial defect coverage, is utilized in microvascular surgery for maxilla-mandibular reconstruction with high success rate, less morbidity, and ability to provide facial symmetry. In addition, it can reduce the risk of adjuvant therapies, such as radiotherapy. Seroma formation at the donor site following LDFF harvest has been reported as a common postoperative sequela. On the other hand, chronic expanding hematoma (CEH) in an LDFF donor site is a rare postoperative complication. in this case report, the authors describe a rare occurrence of a solidified CEH on an LDFF donor site in a male patient 17 years after mandible reconstruction surgery. For treatment, the patient underwent mass resection with drain placement and quilting suture, resulting in reduction of the hematoma and faster healing.
