Binder's Syndrome: Causes, Symptoms, and Treatment
Medically reviewed by Achuta Uppu, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Binder's Syndrome?
Care is often led by a craniofacial surgeon, a surgeon who rebuilds the bones of the face and skull, together with an orthodontist, a dentist who straightens teeth. A pediatrician may also join the care team. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Binder's syndrome?
Binder's syndrome, also called maxillonasal dysplasia, is a rare developmental defect that is present at birth. It causes underdevelopment of the middle of the face, especially the nose and the upper jaw bone, called the maxilla. The nose looks short and flat, with a flattened bridge. Most cases happen for no clear reason, but it can run in families. Boys and girls are affected in similar numbers.
Symptoms
The main signs show up in the face, most often from birth. They can include:
- A short, flat nose with a flattened or depressed nasal bridge.
- A midface that looks flat or set back (midface retrusion).
- A small upper jaw, called maxillary hypoplasia.
- A short columella, the strip of skin and cartilage between the nostrils.
- Malocclusion, meaning the upper and lower teeth do not line up when biting.
- A flat face and, in some people, a lower jaw that looks large.
Some people with Binder's syndrome also have other findings, such as an opening in the roof of the mouth (cleft palate) or small changes in the bones of the spine. The sense of smell is not affected.
Causes and who gets it
The exact cause is not fully understood. The NIH genetic and rare diseases center (GARD) says changes in genes cause the condition. Most cases happen by chance, but some families have more than one affected member. Possible environmental factors include a lack of vitamin K during pregnancy or use of the medicines warfarin or phenytoin, but no factor has been proven. It is rare; one estimate suggests fewer than 1 in 10,000 babies is born with it.
How doctors diagnose it
Doctors diagnose Binder's syndrome from the typical facial features, a detailed patient history, and a physical exam. Imaging tests help confirm it. A CT scan, which uses X-rays and a computer to make cross-sectional pictures of the body, can show the bone changes. An MRI, which uses a magnetic field and radio waves to make detailed pictures, may also be used. These images can show an underdeveloped or missing nasal spine, a thin upper jaw bone, and small or missing frontal sinuses. Special measurements of the skull and face, called cephalometric studies, can also help.
Treatment
Treatment is planned around each person's features and often takes a team of specialists. It may include:
- Braces and other orthodontic devices to straighten the teeth or reposition the jaw.
- Nose reconstruction using bone or cartilage grafts, sometimes taken from the ear or rib.
- Surgery on the upper jaw, called a Le Fort I or Le Fort II osteotomy, in which the upper jaw is cut and moved into a better position.
More than one operation is often needed. The timing depends on severity and age; some children are treated early, while others wait until the late teen years when facial bone growth is done. Support for the patient and family is also an important part of care.
When to see a doctor
Talk to a doctor soon after birth if a baby has a short, flat nose with a flat midface, or if the teeth do not line up as the child grows.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do the first evaluation, keep track of growth and development over time, and refer you to a craniofacial team when surgery is being considered. They can also help coordinate follow-up visits between the specialists involved.
Common questions
What does Binder's syndrome look like?
The face has a short, flat nose with a low or flat bridge and a midface that looks flattened. The upper jaw is small, and the teeth may not meet correctly. The nostrils and the skin between them can look unusual in shape.
Is Binder's syndrome inherited?
Most cases happen by chance and are the only one in a family. But some families have more than one affected member, which suggests genes can play a role. The exact inheritance pattern is not fully understood.
Does it affect breathing or smell?
It does not affect the sense of smell, but the nasal passages can be narrow, and this may need treatment.
Can Binder's syndrome be prevented?
It is present at birth, and there is no known way to prevent it. No suspected environmental factor has been conclusively linked to the condition.
How is it treated?
Braces can straighten the teeth, and surgery can rebuild the nose or move the upper jaw into a better position. Often more than one operation is needed. A team of specialists plans the timing based on each person.
