Craniofrontonasal Dysplasia

CFNS


Presentation

  • Contrary to most X-linked disorders, females are much more severely affected whereas males are asymptomatic or present with a mild phenotype, frequently only displaying hypertelorism.[orpha.net]
  • Abstract A series of 10 patients with craniofrontonasal dysplasia presenting to the Oxford Craniofacial Unit since 1983 is presented.[ncbi.nlm.nih.gov]
  • However, this is quite difficult as facial involvement may not be obvious at such an early age, especially in cases with mild phenotypic presentation.[en.wikipedia.org]
  • In place of the typical craniosynostosis found in CFND, she presented with a superiorly displaced nasion and an anomalously positioned frontonasal suture. This report reveals an unreported malformation in CFND and its surgical implications.[ncbi.nlm.nih.gov]
  • A review of the relevant literature, genetic abnormalities, and pattern of inheritance is presented.[ncbi.nlm.nih.gov]
Broad Thumb
  • Coronal craniosynostosis, hypertelorism, telecanthus, broad grooved nasal tip, dental anomalies, mild syndactyly and broad thumbs, consistent with craniofrontonasal dysplasia are described in a family of four affected females over three generations.[ncbi.nlm.nih.gov]
  • thumbs) and ectodermal dysplasias (dental anomalies, grooved nails, wiry hair).[orpha.net]
High Arched Palate
  • Autopsy of the aborted male foetus showed the following features: High arched palate, a sloping forehead, flattened nose and receding chin, multiple joint contractures, particularly of the mid phalangeal joints, elbows and ankles.[ncbi.nlm.nih.gov]
  • arched palate), skeletal anomalies (clavicle pseudoarthrosis, coronal craniosynostosis, various digital and limb anomalies including syndactyly, clinodactyly of the 5th finger, broad thumbs) and ectodermal dysplasias (dental anomalies, grooved nails,[orpha.net]
  • In addition, individuals with craniofrontonasal dysplasia linked to X may have facial abnormalities including microcephaly, facial asymmetry, palpebral fissures, dry hair and extremely curly, back line of low hair, wide neck, high arched palate, cleft[ivami.com]
  • arched palate, orbital dystopia, low implant of the breasts with asymmetric nipples and volume, webbed neck, hand or foot abnormalities such as clinodactyly (most common is a curved 5th finger) and cutaneous syndactyly (webbed fingers / toes).Females[en.wikipedia.org]
Receding Chin
  • Autopsy of the aborted male foetus showed the following features: High arched palate, a sloping forehead, flattened nose and receding chin, multiple joint contractures, particularly of the mid phalangeal joints, elbows and ankles.[ncbi.nlm.nih.gov]

Esotropia
  • Patients also had cleft lip-cleft palate (10 percent), ear deformities (19 percent), strabismus or esotropia (81 percent), dry frizzy hair (100 percent), syndactyly (14 percent), and nail (100 percent) or other anomalies.[ncbi.nlm.nih.gov]

Eruptions
  • Because of this, correction in later patients was delayed until after eruption of permanent maxillary incisors. The mean anterior interorbital distance was reduced in patients from 184 percent to 98 percent of sex-matched controls.[ncbi.nlm.nih.gov]
Ear Deformity
  • Patients also had cleft lip-cleft palate (10 percent), ear deformities (19 percent), strabismus or esotropia (81 percent), dry frizzy hair (100 percent), syndactyly (14 percent), and nail (100 percent) or other anomalies.[ncbi.nlm.nih.gov]
Large Ears
  • B, Side profile of the boy showing large ears, mandibular prognathia, midface hypoplasia, and, together with the left-hand panel, scaphocephaly.[ncbi.nlm.nih.gov]

Average Intelligence
  • In conclusion, individuals diagnosed with frontonasal dysplasia usually are of average intelligence and can expect a normal life span. The affected individual may die shortly after birth if corrective surgery is not performed as soon as possible.[ruralneuropractice.com]
Papilledema
  • Fundus examination was negative for papilledema, but revealed bilateral mild exocyclotorsion of the fundi. The patient also exhibited hyperopia with astigmatism in both eyes.[ncbi.nlm.nih.gov]

Treatment

  • A treatment algorithm for craniofrontonasal dysplasia based on timing and technique is offered to decrease the need for revision and improve outcomes.[ncbi.nlm.nih.gov]
  • There is no ‘standard treatment’ for people with CFND due to the large variations in phenotypic expression.[en.wikipedia.org]
  • At 10 months after birth when she visited our hospital, signs of craniostenosis were not recognized and cosmetic improvement was considered the main purpose of the treatment.[ncbi.nlm.nih.gov]

  • However, surgical treatment measures are helpful in correcting certain physical defects In such cases, the prognosis is better and the affected individuals are able to live near normal lives, despite challenges as a result of their condition Additional[dovemed.com]
  • Bella came into this world with a poor prognosis, and was diagnosed with a rare syndrome called Frontonasal Dysplasia. Bella has undergone some major surgeries since I last wrote about her.[throughthetulips.ca]
  • Genetic counseling, appropriate treatment and prognosis were explained in detail to the parents but they decided to give consent for do not resuscitate (DNR). Baby died at 36 hours of life.[ruralneuropractice.com]
  • Yet, all of them are very valuable in determining the prognosis of an individual. In the subheadings below, the most common classifications will be explained.[en.wikipedia.org]

Etiology

  • (Etiology) The exact cause of Craniofrontonasal Dysplasia, a rare inherited condition, is currently not known.[dovemed.com]
  • In the last two decades increased knowledge about the structure and function of the human genome has enabled the discovery of the molecular etiologies of most forms of syndromic craniosynostosis, which in turn has allowed for the analysis of normal and[books.google.es]

Epidemiology

  • As such there is little information and no consensus in the published literature regarding the epidemiological statistics. The incidence values that were reported ranged from 1:100,000 to 1:120,000.[en.wikipedia.org]

  • Performing this surgery at such an early age can limit the further development of facial asymmetry, if the asymmetry is caused by the craniosynostosis, and prevents prolonged elevated intracranial pressure (ICP).[en.wikipedia.org]
  • Before corrective surgery, eye drops and ointment are critical to keep the eye moist and prevent blindness if the child is unable to close their eye.[hopkinsallchildrens.org]
  • This study was funded by an unrestricted grant from Research to Prevent Blindness (RPB), New York, N.Y., and the National Institutes of Health CORE Grant P30 EY008098 to the Eye and Ear Foundation of Pittsburgh, Pa.[ncbi.nlm.nih.gov]
