Lambdoid Synostosis

What is Lambdoid Synostosis

Lambdoid craniosynostosis (also known as posterior plagiocephaly) is the rarest of the four types of craniosynostosis. If it occurs, though, it can lead to a flattening of the back of the head on whichever side is affected. It can also offset the growth of the mastoid process on the same side (ipsilateral mastoid bulge).

There are a number of signs that may indicate that the child is experiencing this condition. The ear on the affected side may be further back and toward the fused suture (though this is not always the case). It could also cause one side of the baby’s head to appear flat, one ear to be higher than the other, and the top of the head may tilt to one side.

How We Treat Lambdoid Synostosis

This condition can be treated through surgery. This procedure will help restructure the posterior fossa to create more space and allow for normal brain development. This procedure will also help restore the symmetry of the skull and maintain it throughout their development years.

Similar Conditions

Lambdoid craniosynostosis is rare enough that it is sometimes confused with posterior positional deformational plagiocephaly. It may also be associated with other forms of craniosynostosis, where more than one suture begins to fuse prematurely.

That is why the Cleft & Craniofacial Institute of Utah will carefully monitor and evaluate every case to make sure that your child is properly diagnosed and treated.

Our Expertise

Cleft Lip/Palate

 Cleft lips and palates are one of the most common birth anomalies that affect about 1/600 newborn babies in the United States and around 1/500 in the state of Utah.  Clefts can range from quite mild to fairly severe.  Most of the time they are an isolated anomaly, but are also associated with a number of gentic syndromes.  Depending on what structures are involved dictates the complexity of the treatment plan.   Our team works together with you to make a customized plan for  your baby.  Even the most severe of cases should be able to be treated with only a few surgical interventions by a well coordinated and efficient team.

Craniosynostosis

The skull is made up of several different bones that are joined together by growth plates called "sutures."  Craniosynostosis is a condition where one or more of these sutures fuse prematurely causing an abnormal head shape, decreased cranial volume, and the possiblilty of raised intracranial pressure.  The treatment of craniosynostosis is surgical and the goals of surgery are to increase the volume of the skul and to correct the abnormal appearance of the head shape.  There are two methods of surgical correction: open vault reconstruction and strip craniectomy.  Dr. Griner's extensive training allows him to perform these complex procedures without the need for blood transfusions and spending only 1-2 nights in the hospital.

Syndromes

There are many syndromes that can affect the shape of the head and face and include Aperts, Crouzon, Pfieffer, Treacher Collins, and many others.  Most of these syndromes include many other complex anomalies and need to be treated in a coordinated approach in order to reduce the number of operations the child will need.  These syndromes are rare and require specialists that are very familiar with the intricacies of each syndrome.  Dr. Griner's unique training provided him with extensive experience with craniofacial syndromes and makes him the premier choice to guide the management of your child's needs in Utah.

Ear Deformities

Ear deformities range from mild changes in shape to the complete abscence of an ear and deafness.  Mild deformities can be treated in the first few weeks of life while others will require reconstructive surgery and hearing aids.  No matter the severity, our specialists work together to provide normal appearance and improved hearing.
