Hemimandibular Hypertrophy - Hybrid Variants: Report of Two Cases
A 34-year-old male patient reported to the out-patient department with a complaint of asymmetric appearance of his face. He had been involved in a road accident 15 years ago that had caused severe trauma to his chin. There were no other contributory findings in his dental, medical, and family history. On clinical examination, marked facial asymmetry was observed in the lower region of the face with deviation of the chin to the left. The mandibular body and ramus appeared longer and wider on the right side as compared to the left side []. Intra-oral examination revealed transverse canting of occlusal plane on the right side. Posterio-anterior view of the skull demonstrated elongation of the condyle on the right side. Height of the ramus and body of the mandible were also larger along with transverse canting of the occlusal plane on the right side []. Three-dimensional computed tomography (CT) image showed elongation and enlargement of condyle, ramus, and body of the mandible on the right side []. Scintigram demonstrated hot spots indicative of increased uptake of radioisotope in the condylar region on the right side []. Thus on the basis of clinical and radiographic features, diagnosis of hemimandibular hypertrophy-elongation hybrid variant of the right side was confirmed. Patient was referred to the oral and maxillofacial surgery department, where orthognathic surgery was done and both function and esthetics of the patient's facial structure were restored [].
