ABSTRACT

Hemimandibular hyperplasia (HH) is a facial asymmetry characterized by 3- dimensional unusual growth of half of the mandible which may develop in any age group. Treatment includes primarily surgical, but various treatment options are given in the literature, like partial or high condylectomy with orthognathic surgery and inferior border osteotomy of body of the mandible. This case report of 23-year-old female patient with a history of left-side facial asymmetry. After clinical and radiological examinations standard surgicalorthodontic treatment plan was proposed to the patient. The patient had undergone surgical procedure of high condylectomy and mandibular inferior border recontouring followed by orthodontic treatment which includes initial levelling and alignment. After alignment, patient had undergone mandibular advancement with BSSO (bilateral sagittal split osteotomy). Orthodontic treatment was continued with deep bite correction and final settling of occlusion. The final result obtained with interdisciplinary management by oral surgery and orthodontist was aesthetic for the patient, although slight asymmetry of the chin persisted.
