microsomia

Pronunciation: my-crow-SO-me-ah

Congenital underdevelopment of facial structures, particularly affecting one side of the face.

Full Definition

Microsomia, also known as hemifacial microsomia or craniofacial microsomia, is a congenital condition characterized by underdevelopment of structures on one or both sides of the face. The condition primarily affects the ear, mouth, and mandible, often requiring multiple staged surgical reconstructions throughout childhood and adolescence. Treatment typically involves a multidisciplinary approach including plastic surgery, oral and maxillofacial surgery, and orthodontics.

Usage

Usage note: Distinguish from microtia (ear malformation) and micrognathia (small jaw).
