CROSSED HEMIFACIAL HYPERPLASIA: REVIEW OF THE LITERATURE AND REPORT OF A CASE

الملخص

Crossed hemifacial hyperplasia (CHH) is rare developmental condition that manifested as facial asymmetry along with co-existent enlargement of the opposite extremities. We report a case of CHH in a sixteen years old Libyan female who exhibited obvious enlargement of the lower half of the left side of the face, cheek fullness, swollen lips, displaced philtrum and fissured tongue. The teeth on left side of the jaw are larger than their counterparts on the right side, with deviation of the midline and unequal occlusal plane levels. There is an early eruption of the third molars on the left side of the mouth and the ipsilateral maxillary and mandibular alveolar ridges are enlarged. Extra-oral findings included cutaneous pigmentation on the left side of the neck, elongated and enlarged middle finger of the right hand and hypertrophied toe of the right foot without any mental or neurological defects.
