Facial asymmetry with enlarged frontal sinus and hyperplasia of the cranial, nasal, and mandible bones.

Abstract

The conditions of facial asymmetry are caused by congenital or acquired diseases, and several unclassifiable syndromes with unknown etiologies exist. In this report, a case of facial asymmetry with enlarged frontal sinus and hyperplasia of the frontal cranial bone and nasal bone is presented. Although the etiology of the facial malformation was clear, it was thought that the cause of the enlarged frontal sinus was related to the unidentified bony hyperplasia and facial asymmetry related to hemimandibular hyperplasia.
