What are the treatment options for Pfeiffer syndrome?
Children both with Pfeiffer syndrome types 2 and 3 will need multiple surgeries for the reconstruction of the skull, hands and feet, and other joints, and treatment for affected organs. Children with type 1 are treated with early surgery and for physical and occupational therapies. The outlook for type 1 is much better than for types 2 and 3.
What happens if Pfeiffer syndrome is not treated early?
Children with Pfeiffer syndrome types 2 and 3 often have delayed development and other issues with the brain and nervous system. Without early treatment, they’re also more likely to have life-threatening health problems.
How many types of Pfeiffer syndrome are there?
There are three types of Pfeiffer syndrome. All of them affect a child’s appearance, but types 2 and 3 are more severe. They can cause delays in development, as well as other issues with the brain and nervous system. Treatment starts soon after birth.
Is Pfeiffer syndrome dominant or recessive?
This type is inherited in an autosomal dominant pattern. Most individuals with type 1 Pfeiffer syndrome have normal intelligence and a normal life span. Type 2 includes a cloverleaf-shaped skull, due to extensive fusion of bones, as well as severe proptosis.

Can Pfeiffer syndrome eyes be corrected?
There is no cure for Pfeiffer syndrome, but it can often be treated. The treatment for Pfeiffer syndrome depends on the type and the symptoms it's causing. The main treatment for Pfeiffer syndrome is surgery.
How long can you live with Pfeiffer syndrome?

Serious complications of Pfeiffer syndrome include respiratory problems and hydrocephalus . Breathing problems are generally related to trachea abnormalities or blockages in the midface. Hydrocephalus can lead to mental impairment if not treated. Further, facial deformities may cause severe displacement of the eyes and make it hard to close the eyelids. Children with type 2 and 3 may have seizures.
What is Pfeiffer syndrome?
A Word From Verywell. Pfeiffer syndrome is a rare genetic condition that causes premature fusion of the bones of the skull of a baby while in its mother's womb. The early fusion causes deformities of the head and face. There are three subtypes of Pfeiffer syndrome and all affect appearance, but types 2 and 3 cause more problems, ...

In addition, there is an underdeveloped upper jaw ( maxillary hypoplasia ). More than 50 percent of children with Pfeiffer syndrome have hearing loss; dental problems are also common. In people with Pfeiffer syndrome, the thumbs and first (big) toes are wide and bend away from the other digits ( pollex varus and hallux varus ).
What are the characteristics of Pfeiffer syndrome?
Many of the characteristic facial features result from the premature fusion of the skull bones ( craniosynostosis ). The head is unable to grow normally, which leads to a high prominent forehead ( turribrachycephaly ), and eyes that appear to bulge ( proptosis) and are wide-set ( hypertelorism ). In addition, there is an underdeveloped upper jaw ( maxillary hypoplasia ). More than 50 percent of children with Pfeiffer syndrome have hearing loss; dental problems are also common.

How many births are affected by Pfeiffer syndrome?
Pfeiffer syndrome affects about 1 in 100,000 births. The syndrome is named after German geneticist Rudolf Arthur Pfeiffer (1931–2012), who described it in 1964.
What is Pfeiffer syndrome?
Pfeiffer syndrome (OMIM 101600, also known as type 5 acrocephalosyndactyly, craniofacial-skeletal-dermatologic dysplasia, or Noack syndrome) is part of a family of syndromes characterized by acrocephalosyndactyly – the premature closure of skull sutures (craniosynostosis) that are separated into five types [1]. First described in 1964 by German geneticist, Rudolf Arthur Pfeiffer who noted eight individuals in three generations of a family with notable abnormalities of head, hands, and feet in an autosomal dominant inheritance pattern. Since his discovery, at least six additional Pfeiffer pedigrees and at least a dozen sporadic cases have been recorded, making Pfeiffer syndrome's incidence rate of 1 in 100,000 individuals [2], [3], [4]. Given the paucity of cases, there is scarce follow up data on patients [1]. Pfeiffer syndrome is genetically heterogeneous and caused by mutations in FGFR1 and FGFR2. It has been noted that both Pfeiffer and Crouzon syndrome, another member of the acrocephalosyndactyly family, are caused by similar pathological variant FGFR2 mutations [5], [6], [7]. Interestingly, there have been no reports of scoliosis in Pfeiffer syndrome, but there have been case reports of scoliosis in Crouzon syndrome, begging the question if the patient's craniosynostosis syndrome has been misclassified [8]. Due to this genetic and phenotypic overlap between Crouzon and Pfeiffer syndrome, patients with the same pathologic variant have been diagnosed as the other in the past. However, there are certain pathologic variants exclusively reported as Pfeiffer syndrome in medical literature [9]. Pfeiffer syndrome is subdivided into three broad phenotypes with overlap. Point mutations in Ser351Cys of FGFR2 meaning cysteine replacement of serine at amino acid codon 351 is associated with a more severe phenotype and decreased survival [10]. Type 1 (classic) is more commonly hereditary with sporadic cases reported while in type 2 and 3 only sporadic cases have been reported except for an exclusive type 2 pedigree. Type 1 is associated with FGFR1 or 2 mutations while type 2 and 3 are exclusively FGFR2 mutations. 2
What are the different types of Pfeiffer syndrome?
Pfeiffer syndrome can be subdivided into three subtypes with overlap: Classic or type 1 is the most mild with brachycephaly (flat head syndrome), midface hypoplasia, finger and toe abnormalities, normal lifespan and intellect, with good outcome post surgery. Type 2 is specifically characterized by trilobolated or cloverleaf skull, extreme proptosis, finger and/or toe abnormalities, elbow ankylosis and/or synostosis, beak-shaped nose, and developmental and neurologic complications (ie, hydrocephalus) due to limited brain growth. Type 3 is classified by the more severe abnormalities of type 2 but without the characteristic cloverleaf skull ( Table 1 ). Types 2 and 3 are characterized by shortened life expectancy due to neurologic and respiratory problems [4, 14].
Is Pfeiffer syndrome autosomal dominant?
Genetic counseling should be considered for affected patients prior to conceiving as Pfeiffer syndrome's autosomal dominant inheritance pattern results in 50% chance of transmission. Advanced paternal age is a noted risk factor for de novo or sporadic mutation [13].
How to treat craniofacial abnormalities?
These are done with fronto-orbital and Le Fort III advancement starting in the first year of life (as early as three months of age) with suturectomy to release the synostotic sutures and open up intracranial space for bone growth. The second stage involves mid-facial surgery to reduce exophthalmos and midfacial hypoplasia. If TCS is present, patients usually eventually require tracheostomy to treat the side effect of obstructive sleep apnea due to combined maxillary hypoplasia, choanal stenosis, and macroglossia. Cosmetic surgical repair can be done for other abnormalities relevant to each patient's phenotype. An interprofessional care team involving neurosurgery, pediatrics, plastics, and skilled nursing among others is the best approach for favorable patient outcome with a plan tailored to the individual patient's strengths and weaknesses [15, 16].
Is Pfeiffer syndrome detected in the prenatal period?
Pfeiffer syndrome is rarely detected in the prenatal period. As few as 6 cases have been identified prenatally, usually by ultrasound showing presence of cloverleaf skull deformity [11, 12]. Other sonographic signs include brachycephaly, acrocephaly, craniosynostosis, hypertelorism, and hand feet anomalies, but are not as reliably seen.
Is Pfeiffer syndrome a good prognosis?
As mentioned, type 1 Pfeiffer syndrome has a good prognosis with normal life expectancy and intellect, although long term follow up has been poor due to paucity of cases. This prognosis is assuming that the patient undergoes multiple staged surgeries starting within the first year of life. Type 2 and 3 Pfeiffer syndrome have poor prognosis with neurodevelopmental complications and childhood death being common. Severity of syndrome is the most relevant factor in prognosis. Craniofacial appearance improves with age. A study reviewing clinical course of seven children with type III Pfeiffer syndrome noted that even given severe manifestations, aggressive medical and surgical management can result in favorable outcomes [1, 14, 15].
Is Pfeiffer syndrome a rare disease?
Pfeiffer syndrome is a rare disease with both specific bony abnormalities and variant phenotypes from patient to patient that make it a distinct acrocephalosyndactyly syndrome. Given the paucity of follow up, this case provides a unique assessment of long-term viability of pediatric surgical modifications and the body's physiological adaptation to accommodate them. Imaging features consist of characteristic craniosynostosis patterns including brachycephaly, acrocephaly, or cloverleaf shaped skull, brain stem herniation, obstructive hydrocephalus, pelvic kidneys, compressed gallbladder, and hydronephrosis.
