A significant proportion of facial asymmetry cases are caused by abnormal growth of the mandibular condyles. Surgical management is generally based on a condylectomy performed through a pre-auricular transcutaneous access. However, this approach entails potential neurovascular, salivary, and aesthetic complications. In this study, a proof-of-concept evaluation was performed of a novel minimally invasive technique for condylectomy performed through an intraoral approach. Based on precise three-dimensional virtual planning to define intraoperative references, this technique provides an excellent access for total or partial condylectomy through a limited intraoral incision. Piezoelectric surgery with customized attachments enables the safe, accurate execution of the condylectomy. In addition, experience gained in seven consecutive cases suggests that the need for coronoidectomy can be obviated, surgical time is reduced to an average of 16.9 min, and postoperative morbidity is minimal. This alternative intraoral approach could become the treatment of choice for most condylar hyperplastic conditions.
