We can distinguish several large groups of facial malformations, they are either isolated or belong to syndromes or chromosomal abnormalities.
The main deformities of the face are:
- Facial slits
- Otomandibular dysplasia (malformations associating hypoplasia or agenesis of the ear and mandibular hypoplasia)
- Congenital dysmorphisms
- Cysts and fistulas of the face
- Macroglossia and microglossia (abnormal increase or decrease in the volume of the tongue)
- Paralytic malformations
- Vascular malformations (Angiomas, lymphangiomas, arteriovenous malformations, etc.)
