Apert Syndrome

A condition that affects early facial and limb development, managed with coordinated care to support your child’s growth and function.

What Is an Apert Syndrome?

Understanding Apert Syndrome

Apert syndrome is a rare genetic craniofacial condition characterized by the premature fusion of certain skull bones and abnormalities affecting the face, hands, and feet. This early fusion, known as craniosynostosis, alters normal skull and facial growth and can impact breathing, vision, and jaw alignment.

Because the skull cannot expand normally to accommodate brain growth, facial structures may develop differently over time. With early diagnosis and coordinated medical care, many individuals with Apert syndrome achieve healthy development and lasting, positive outcomes.

Defining Characteristics

Apert syndrome can involve a range of differences affecting both facial growth and the hands and feet. These features vary in type and severity and may influence skull shape, midface development, and the formation and separation of the fingers and toes. Understanding the specific pattern of findings helps guide evaluation and allows care to be planned thoughtfully over time.

Eye & Eyelid Abnormalities

Shallow eye sockets that may cause prominent eyes, a widened appearance between the eyes, eyelid exposure, and vision-related concerns.

Midface Underdevelopment

Underdevelopment of the upper jaw and cheekbones, which can contribute to breathing difficulties and dental crowding.

Jaw & Bite Misalignment

A recessed upper jaw that may lead to malocclusion, chewing challenges, and speech differences.

Hand & Foot Differences

Fusion of fingers and toes, which can affect fine motor skills and mobility and may require surgical correction.

Coordinated Pediatric Specialty Care

Children with Apert syndrome require coordinated care across a dedicated team, with each step aligned to support skull and facial growth, as well as hand and foot development. Care is thoughtfully timed—from early evaluation through staged treatment and long-term follow-up—to ensure safe, consistent progress as your child grows.

Cranial Vault Procedures

Cranial vault procedures for Apert syndrome are performed to release prematurely fused skull sutures and support normal brain and skull development. In early infancy, some children may benefit from endoscopic techniques, while older children may require cranial vault remodeling, fronto-orbital advancement, or distraction-based procedures to reshape the skull and support more normal craniofacial growth.

Le Fort III Advancement

The Le Fort III osteotomy is used in Apert syndrome to advance the underdeveloped midface, including the cheekbones and upper jaw. Often performed between 6 and 10 years of age, treatment may involve distraction-based techniques or more traditional midface advancement procedures depending on airway needs, eye protection concerns, and long-term craniofacial development.

Monobloc Advancement Illustration

Monobloc Advancement

Monobloc frontofacial advancement is used in more severe cases of Apert syndrome to move the forehead and midface forward together. Often performed between 6 and 10 years of age, this procedure may use distraction-based techniques to improve intracranial space, eye protection, airway function, and overall craniofacial balance.

Monobloc Facial Bipartition Illustration

Monobloc Facial Bipartition

Monobloc facial bipartition is used in selected cases of Apert syndrome to advance the forehead and midface while correcting increased spacing between the eyes and reshaping the central facial skeleton. Often performed during childhood, this procedure may use distraction based techniques to improve facial balance, airway function, eye protection, and long term craniofacial development.

Orthognathic Surgery

Orthognathic surgery is commonly performed in Apert syndrome after facial growth is complete to refine jaw position and correct bite alignment. Typically performed during the late teenage years or early adulthood, this procedure repositions the upper jaw, lower jaw, or both to improve function, facial balance, and long-term stability following earlier craniofacial procedures.

Frequently Asked Questions

Our advanced jaw surgery procedures are designed to enhance your quality of life. With a focus on precision and patient comfort, we ensure optimal results tailored to your unique needs.

Choosing Your Care Team

How important is experience in treating Apert Syndrome?

Apert Syndrome often involves complex surgical, developmental, and functional concerns that require coordinated, specialized management. Outcomes depend heavily on a surgeon's training, clinical judgment, and familiarity with the nuances of this condition. Teams that regularly treat patients with Apert Syndrome are typically better equipped to manage both immediate surgical needs and long-term outcomes.

What is the difference between private practice and academic or hospital-based care?

In a private practice setting, care is often more streamlined and consistent, with the same surgeon closely involved in evaluation, treatment planning, surgery, and follow-up.

In academic or hospital-based settings, care may involve a larger team that can include residents or fellows participating under supervision. Both models can provide excellent care, but the structure and continuity of treatment may feel different. At our center, your care is delivered directly by your surgeon — not by residents, fellows, or surgeons in training.

Who will perform my surgery or procedure?

It is important to understand who is performing each part of your treatment. In some settings, the attending surgeon performs all critical portions of the procedure, while in others trainees may assist or participate under supervision. This should be discussed clearly in advance. At our center, your surgeon performs all critical portions of the procedure.

Will trainees be involved in my care?

Depending on the treatment setting, residents, fellows, or students may be involved in aspects of care. Patients and families should feel comfortable asking about their role and how care is supervised throughout treatment.

At our center, there are no residents or fellows involved in performing surgery.

Who will follow me after treatment or surgery?

Long-term follow-up is an important part of care for many conditions managed at our center. In some practices, post-treatment care may be shared among multiple providers, while in others the surgeon remains closely involved throughout recovery and monitoring. At our center, your surgeon personally follows you throughout recovery and long-term care.

How involved is the surgeon throughout the process?

Comprehensive care includes direct surgical involvement in evaluation, treatment planning, surgery, and long-term follow-up. Consistency throughout the process helps maintain continuity of care.

At our center, your surgeon is directly involved at every stage — from initial evaluation through treatment and follow-up.

Understanding Apert Syndrome

What is Apert Syndrome?

Apert Syndrome is a genetic condition characterized by premature fusion of the skull bones along with fusion of the fingers and toes, a condition called syndactyly. The early fusion of skull sutures restricts normal skull and facial development, resulting in a prominent forehead, midface underdevelopment, and characteristic hand and foot differences.

What causes Apert Syndrome?

Apert Syndrome is caused by mutations in the FGFR2 gene. The vast majority of cases arise as completely new mutations with no prior family history. This means it was not inherited and was not caused by anything either parent did or was exposed to during the pregnancy.

How does Apert Syndrome affect the face?

The midface is typically underdeveloped, resulting in a flat facial profile, a prominent forehead, widely spaced and protruding eyes, and a jaw relationship where the lower jaw extends beyond the upper jaw. The roof of the mouth may be highly arched or cleft.

Does Apert Syndrome affect the brain?

Premature skull fusion can restrict brain growth and increase intracranial pressure. Early evaluation and monitoring by a neurosurgeon is a standard part of care for children with Apert Syndrome.

Does Apert Syndrome affect breathing?

Yes. Midface underdevelopment frequently causes narrowing of the nasal airway, obstructive sleep breathing, and in some cases significant airway compromise. Airway monitoring and management are important components of care, particularly in early childhood.

Are there learning or developmental differences?

Developmental outcomes vary. Some individuals with Apert Syndrome have typical cognitive development, while others may benefit from early developmental and educational support. Close monitoring and early intervention are important.

Surgical & Treatment Considerations

What surgeries are typically involved in Apert Syndrome?

Surgical care is staged over many years and typically includes cranial vault surgery in infancy to relieve intracranial pressure, hand surgery to separate fused digits, midface advancement during childhood or adolescence to improve the airway and facial profile, and jaw surgery in adolescence or adulthood to address the bite.

What is the role of midface advancement in Apert Syndrome?

Midface advancement moves the bones of the upper face and jaw forward to improve facial balance and relieve obstructive breathing. The procedure may be performed in stages and is often combined with distraction techniques to achieve the necessary degree of advancement.

When is jaw surgery considered?

Orthognathic surgery to correct the bite and jaw relationship is typically planned after facial growth is complete. It is coordinated with orthodontic treatment and may be combined with additional facial contouring procedures.

Long-Term Monitoring & Growth

Will my child need follow-up throughout childhood and adolescence?

Yes. Apert Syndrome requires staged surgical care and ongoing monitoring of intracranial pressure, facial growth, airway function, hand function, vision, speech, dental development, and bite alignment across childhood, adolescence, and into adulthood.

Can individuals with Apert Syndrome live full lives?

Yes. With well-coordinated, staged care across multiple specialties, many individuals with Apert Syndrome go on to live meaningful, independent lives. Outcomes are influenced by the severity of the condition and the quality and timing of care.

Traveling & Out-Of-Town Patients

Do families travel to your center for treatment?

Yes. We regularly care for families traveling from outside the region for specialized craniofacial care.

How long do families typically need to stay near your center?

Because Apert Syndrome is managed through staged procedures across many years, the local stay is discussed for each procedure individually. After cranial vault surgery in infancy, families should generally plan for approximately two to three weeks locally so the team can closely monitor intracranial pressure, healing, and airway status before travel — this is genuine ongoing clinical monitoring. For midface advancement using distraction, the treatment timeline is extended and the full plan is discussed with families well in advance. For orthognathic jaw surgery in adolescents and adults, patients are typically discharged within two to three days and recovering well. Out-of-town patients should plan to remain locally for approximately one week primarily to attend their first post-operative visit, where the surgeon confirms healing and clears travel home. Air travel is generally appropriate within approximately two weeks. All timelines vary based on the complexity of the procedure, recovery progress, and the patient's overall condition, and your surgeon will provide specific guidance for each stage of treatment.

Is driving home different from flying?

Yes. Ground travel is generally permitted sooner than air travel. Cabin pressure changes are a particular consideration after cranial and midface procedures, and flying clearance is procedure-specific. Your surgeon will advise accordingly.

What can families expect during evaluation and treatment planning?

Evaluation at our center includes craniofacial examination, airway assessment, imaging review, and a detailed discussion of the staged treatment plan across procedures. Families leave with a clear understanding of what to expect at each stage and how follow-up between visits will be coordinated.
