Coronal Synostosis

What is Coronal Synostosis

The skull in an infant is not a single, complete structure. It is a number of smaller bones that are separated by a fibrous element called a suture. The coronal sutures separate the frontal and parietal bones of the skull.

Coronal craniosynostosis occurs when these sutures close too quickly and start to fuse together. The results of this condition affect the side of the skull, causing the forehead and the frontal lobe grow and expand forward. Other noticeable effects include a flattened or recessed forehead and eye sockets that appear elevated and tilted.

One indicator that a baby is currently experiencing this condition is that they will tilt their head to the side a little, because it helps not stop seeing double.

How We Treat Coronal Synostosis

Surgical treatment can correct this issue, and, while every patient has individual circumstances, it is usually performed between the ages of 9 and 12 months.

In some cases, the posterior sutures may also need to be treated. In which case, we will take a staged approach, starting around the 3 to 6-month mark and then followed up by the fronto-orbital advancement at 9 to 12 months.

If the condition is treated early enough, the procedure we use is minimally invasive and leaves only very small scars. After the procedure, the child will need to wear a helmet for several months to make sure we achieve the best possible results.

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.






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. 



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.

Staged palate repairs

Staged palate repairs were implemented to try and reduce the chance of stunting the upper jaw growth and needing to have it surgically advanced later in life, while at the same time allowing normal speech to develop.  We know from several studies that the growth of...
