Congenital hemifacial hyperplasia-A diagnostic dilemma

CHH is a rare developmental pathology and often presents a diagnostic dilemma to a clinician. It is characterized by marked unilateral overgrowth of hard and soft tissues of the face that is present since birth and advances with age, mostly till puberty. Though aetiology remains unknown, several factors could be considered including hormonal imbalances, diseases involving the neural system, vascular conditions, lymphatic abnormalities, mechanical influences and congenital syphilis. Hence, desired investigations should be done to rule out syndromes causing facial asymmetry. Since, management is considered when aesthetics are a prime concern, it should be planned only after growth cessation. We, hereby, present a case of 10-year-old male patient reported with chief complaint of asymmetry on left side of face from birth to supplement existing clinical knowledge.
