Sammanfattning

Introduction and purpose – Hemimandibular hyperplasia (HH) is a developmental unilateral three-dimensional enlargement of the mandible resulting in distortion of the mandible with occlusal, functional and aesthetic problems. HH typically becomes apparent in puberty. The treatment depends on the growth activity. Ongoing growth activity can be detected with a bone scintigraphy, and treatment and observation with an occlusal splint. In order to treat the dentofacial deformity both the maxilla and the mandible often need to be corrected, because the maxillary growth compensates for the mandibular growth deviation. The purpose of this article is to elucidate the aetiology, incidence and treatment of hemimandibular hyperplasia. As a supplement, a presentation of a group of patients treated in the Department of Oral and Maxillofacial surgery, Aarhus University Hospital, Denmark, is included. Material and methods – 26 patients with hemimandibular hyperplasia or hemimandibular elongation in treatment at the Department of Oral and Maxillofacial Surgery, Aarhus University Hospital, Denmark, were reviewed. Radiographic analysis and patient records were evaluated and related to the literature. Results and conclusions – Hemimandibular hyperplasia should be diagnosed as early as possible in order to assess abnormal growth activity and growth pattern and determine the optimal time for treatment. Compensatory growth and dentoalveolar alterations should be minimized and high condylectomy considered in cases with active growth. Two-jaw surgery is needed to correct deformities of the mandible and maxilla. Stability of the orthognathic surgical treatment is difficult to predict because hyperactive growth may recur after high condylectomy and orthognathic surgery. The aetiology is unknown, though genetic determinants, trauma and infection are discussed as possible factors.
