Congenital Hemifacial Hypertrophy: A Case With Unilateral Tonsillar Hypertrophy and Parapharyngeal Space Lipoma.

Congenital hemifacial hypertrophy, an uncommon developmental disease, is characterized by unilateral overgrowth in at least one body part, which can result in significant asymmetry. Meckel reported the first patient of congenital hemifacial hypertrophy in 1822. Since then, numerous cases have been investigated. This study reports a 2-year-old child diagnosed with hemifacial hypertrophy combined with unilateral tonsillar hypertrophy and parapharyngeal space lipoma. We concentrated on the treatment options as well as the related head and neck symptoms.
