Abstract

Introduction: The purpose of the study was to provide an overview of our initial experience utilizing urinary bladder matrix (UBM) for reconstructing avulsed injuries resulting from trauma. Materials and Methods: This retrospective case series evaluated patients presented with avulsed soft tissue injuries to the head and neck who underwent reconstruction with UBM. Patients were treated by Oral and Maxillofacial Surgery Service in Louisiana State University Health Sciences Center (Baton Rouge, LA). Descriptive variables were collected. Descriptive statistics were calculated. Results: Eight patients (mean age 55.8 y) met our inclusion criteria. Wounds were located in the scalp (n=2, 25%), mandible (n=2, 25%), upper eyelid (n=1, 12.5%), cheek (n=1, 12.5%), nose (n=1, 12.5%), or neck (n=1, 12.5%). The depth of the wound extended from the skin to the subcutaneous tissue (n=1, 12.5%), muscle (n=2, 25%), bone (n=3, 37.5%), and/or cartilage (n=1, 12.5%). The mean wound diameter was 47.9 cm2(range 17-85 cm2). Wounds were classified as acute (n=6, 75%) or chronic wounds (n=2, 25%). At 6 months, all patients had achieved complete healing with no need for additional surgical procedures (n=8, 100%) with a mean healing time of 36.5 days (range 14-90 d). Conclusion: Urinary bladder matrix minimize donor-side morbidity, eliminates contraction, and offers a wide range of product sizes to cover a wide range of maxillofacial soft tissue defects in a single-stage manner.
