Hemifacial hypertrophy (also termed facial hemihypertrophy, [2] facial hemihyperplasia, [2] or Friedreich's disease) [3] abbreviated as (HFH) is rare congenital disease characterized by unilateral enlargement of the head and teeth. [4] [5] It is classified as true HFH (THFH) with unilateral enlargement of the viscerocranium, and partial HFH (PHFH) in which not all structures are enlarged. Hemifacial hypertrophy can cause a wide spectrum of defects or may involve only muscle or bone. [5] it is usually treated surgically. [6] It is believed to be a minor form of hemihypertrophy. [7]
