Supra-Pericranial vs Sub-Pericranial Dissection

Today, we welcome back Dr. Andrew Jenzer, a renowned expert in oral and maxillofacial surgery and a Clinical Associate in the Department of Surgery at Duke University, where he specializes in craniomaxillofacial trauma and reconstructive surgery. Dr. Jenzer is known for his expertise in the "coronal approach," a technique vital to his field, and in this conversation, he shares his wealth of knowledge and practical tips for mastering it. He outlines the overall approach before detailing the nuances of implementing it. You’ll discover how to conceptualize the layers of the skull, transition to exposing the zygomatic arch, and how to best approach the upper facial skeleton. We discuss the best resources for learning about the method, details on how to make the initial incision, and common misconceptions about the approach. You’ll also learn how to prepare effectively for the procedure, reduce the probability of bacterial infection and other complications, navigate various tissues, leverage Pitanguy’s Line, and much more.
