Surgical Corrections for Hemimandibular Hyperplasia: a Case Report
Keywords:
Orthognathic surgery, Facial asymmetry, Hemimandibular hyperplasia, Condylar hyperplasiaAbstract
Hemimandibular hyperplasia is characterized by excessive unilateral growth of the mandible. This causes facial asymmetry resulting in facial and dental imbalance followed by chewing difficulties and unsatisfactory appearance. A 3-dimensional evaluation of facial and jaw bones is required for treatment planning in this case. Orthognathic and facial recontouring surgery can accomplish sound facial, skeletal, and dental treatment outcomes.
This case report describes the evaluation, treatment planning, and complications of an 18-year-old female patient who suffered from hemimandibular hyperplasia. Her lower jaw shifted to the left side with an obvious asymmetric face. Anterior and posterior crossbite was found on the left. The patient had pre-surgical orthodontic treatment for 2 years. The patient underwent Le Fort I osteotomy and bilateral sagittal split osteotomy with mandibular recontouring procedures with satisfactory results.
