short maxilla

A short maxillary length can result from many congenital and acquired causes. If seen in an antenatal ultrasound scan, it is often considered to have a high association with trisomy 21 .

Congenital conditions

Many conditions that can cause midfacial hypoplasia will result in a short maxillary length. These include

• 18q deletion syndrome
• Alport syndrome
• fetal alcohol syndrome
• fetal valproate syndrome
• fetal Warfarin syndrome
• Stickler syndrome group

Acquired conditions

In acquired situations (i.e. in an adult), previous surgery (e.g. for tumor resection) and trauma are important considerations.
