The intraoral vertical ramus osteotomy (IVRO) is a technically straightforward and useful technique with many applications, including management of horizontal mandibular excess, mandibular asymmetry and correction of minor mandibular deficiency. IVRO has a significant advantage over sagittal split osteotomy (SSO) from the standpoint of inferior alveolar nerve injury and risk of unfavorable split. IVRO also may be more forgiving than SSO in patients with TMJ disorders because of a condylotomy effect. IVRO has likely been criticized as a mainstream ramus osteotomy, as maxillomandibular fixation (MMF) is required with the traditional technique. Internal fixation can be readily applied to IVRO and predictably eliminate MMF. Surgical protocols for safe IVRO with internal fixation technique will be discussed in detail during this 60-minute webinar.
Learning Objectives
At the conclusion of this program, participants should be able to:
- Explain the indications and limitations of IVRO.
- Distinguish the virtual planning considerations for IVRO.
- Describe the digital workflow for cutting guide fabrication.
- Integrate IVRO with internal fixation into daily orthognathic surgery practice.

Susie Lin, DDS, MD
Dr. Lin received her DDS from New York University College of Dentistry and MD from Vanderbilt University School of Medicine. She completed her OMS residency training at Vanderbilt University Medical Center (VUMC) before she was in full-time private practice for approximately 10 years. She completed her craniofacial surgery fellowship at Chang Gung Memorial Hospital in Taiwan before returning to VUMC as full-time faculty and residency research coordinator. Her research interests include hypotensive anesthesia techniques in orthognathic surgery with regard to intraoperative blood loss, quality of surgical field and postoperative nausea and vomiting; effects of age and presence of third molars on the occurrence of unfavorable splits during SSO; use of primary septal cartilage graft for unilateral cleft rhinoplasty; and the effects of IVRO with rigid internal fixation on the TMJ and prevalence of surgical complications. Dr. Lin serves as an ABOMS Board examiner and a reviewer for JOMS.

Samuel J. McKenna, DDS, MD, FACS
Dr. McKenna is a graduate of UCLA School of Dentistry and Vanderbilt University School of Medicine. He completed his OMS residency at VUMC, where he is Professor and Chair of Oral and Maxillofacial Surgery. Before assuming the Chair position, Dr. McKenna was Residency Program Director for nearly 20 years. He has a busy academic/hospital-based practice that encompasses the full traditional scope of clinical OMS practice with an emphasis on orthognathic, facial trauma, cleft, oral and maxillofacial pathology and TMJ surgery. Dr. McKenna’s interest in IVRO stems from 40 years of experience applying this procedure to the management of skeletal jaw deformities and TMJ disease.
