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 1.
Congenital conditions
Many conditions that can cause midfacial hypoplasia will result in a short maxillary length. These include:
Acquired conditions
In acquired situations (i.e. in an adult), previous surgery (e.g. for tumour resection) and trauma are important considerations.
