Surgery-early approach combined with condylectomy for correction of severe facial asymmetry with mandibular condylar hyperplasia: a case report.

Abstract

In patients with unilateral mandibular condyle hyperplasia, whether to perform condylectomy and orthognathic surgical procedures at the same time or orthognathic surgery in two stages for remains controversial. Reported here is a case of facial asymmetry with mandibular condyle hyperplasia, for which condylectomy and orthognathic surgery procedures were performed at the same time. A 28-year-old woman was presented to our department with chief complaints of left deviation of the mandible and right temporomandibular joint (TMJ) noise. Findings obtained in several imaging examinations led to a diagnosis of facial asymmetry associated with right mandibular condyle hyperplasia. Following 3 months of preoperative orthodontic treatment, in October 2018 under general anesthesia the patient underwent a right mandibular condylectomy, Le Fort I osteotomy, right mandibular sagittal split ramus osteotomy, and left mandibular inverted L ramus osteotomy. In examinations up to 3 years after surgery, good results were noted. For this case of severe facial asymmetry with mandibular condyle hyperplasia, early surgery and condylectomy were performed simultaneously to significantly shorten the total treatment time. The effectiveness of a surgery-early approach was confirmed by no postoperative findings indicating abnormalities in the TMJ or retroversion.
