Oral manifestations and rehabilitation in Fraser syndrome: A case report.

Fraser syndrome (FS) is a rare recessive autosomal genetic disorder characterized by multisystemic malformations typically comprising cryptophthalmos, syndactyly, and renal defects. We report the case of a 16-year-old patient who exhibited facial asymmetry, short roots, hypodontia, and malocclusion. Oral rehabilitation included orthodontics, exodontia, and osseointegrated dental implants to improve the patient's self-esteem and eating function. We suggest short roots and hypodontia assessment in patients with FS.

Oral healthcare in Fraser syndrome.

Fraser syndrome is a rare autosomal recessive disorder characterized by renal agenesis, cryptophthalmos, syndactyly, and laryngeal stenosis. Oral manifestations are sparsely described in the literature, and patients with this syndrome might require special dental management considerations because of the associated cardiac, renal, and cognitive defects. In this report, we describe the oral/dental findings in a 22-year-old girl with Fraser syndrome, and discuss the dental management.

Fraser syndrome with laryngeal webs: Report of two cases and a review of the literature.

Fraser syndrome is a rare genetic disorder characterized by cryptophthalmos, syndactyly and laryngeal atresia. Although laryngeal webs occur uncommonly, they are the main cause of death in the first week of life in these patients. In this paper, we report two cases of Fraser syndrome with laryngeal webs. One of them was a twelve-year-old girl, primarily diagnosed with a supraglottic laryngeal web. In the course of treatment, a second web was also identified at the level of vocal cords, which is to our knowledge the first case of Fraser syndrome with two laryngeal webs in different levels.

Síndrome de Fraser: relato de caso nas vias lacrimais / Fraser Syndrome: case report in lacrimal system

A síndrome de Fraser é uma condição sistêmica caracterizada por criptoftalmo, sindactilia e anomalia da genitália, podendo se associar com alterações dos rins, do ouvido, do nariz, da laringe e do esqueleto. O criptoftalmo pode representar um achado isolado, representado por herança autossômica dominante, associado a outras anomalias congênitas, relatado como herança autossômica recessiva. Criança do sexo feminino, 9 meses, avaliada no ambulatório de vias lacrimais da Universidade Federal de São Paulo. Filha de pais consanguíneos. Ao exame, foram observados criptoftalmo total à esquerda, epífora em olho direito associada à secreção mucopurulenta, nariz em sela, implantação baixa das orelhas, malformação de conduto auditivo, aumento de grandes lábios e sindactilia de mãos e pés. A tomografia de crânio evidenciou braquicefalia ausência de septo pelúcido, proeminência dos ventrículos laterais, importante falha óssea na calota craniana, presença de afilamento do manto tecidual cerebral, fossa posterior pequena, desorganização do segmento anterior, afacia e descolamento total da retina.

Fraser syndrome is a systemic condition characterized by cryptophthalmos, syndactyly and abnormal genitalia, which may be associated with urinary tract, ear, nose, larynx and skeletal abnormalities. Cryptophthalmos can be an isolated finding (that has been reported as an autosomal dominant trait) or associated with other congenital anomalies (reported as an autosomal recessive disorder). Child, female, nine month of life, evaluated in the lacrimal setor of Federal University of São Paulo. Child of consanguineous parents. Her physical examination showed total unilateral cryptophthalmos (left side), epiphora (right side) with mucopurulent discharge, depressed nasal bridge, low set ears, atresia of the external auditory canal, prominent labia majora and syndactyly of the fingers and toes. Ocular ultrasonography showed brachycephaly, absence of septu pellucidum prominence of the lateral ventricles, a major bone defect in the skull, the presence of thinning of the mantle tissue of the brain,a reduced anterior-posterior ocular diameter, anterior segment disorganization, absence of the lens and total retinal detachment in the left eye.

Congenital High Airway Obstruction Syndrome (CHAOS) as part of Fraser syndrome: ultrasound and autopsy findings.

Congenital High Airway Obstruction Syndrome (CHAOS) is a potential lethal condition. We describe a case report of CHAOS, with additional malformations diagnosed at 20 weeks. Autopsy findings are suggestive for Fraser syndrome (cryptophthalmos-syndactyly syndrome; OMIM 219000). The diagnosis was confirmed by mutation analysis of FRAS1.

Case report: hypodontia and short roots in a child with Fraser syndrome.

BACKGROUND: Fraser syndrome is a rare autosomal recessive disorder of which there has only previously been one case reported in the dental literature. The main characteristics are cryptophthalmos, syndactyly and genital abnormalities. Orofacial findings reported are: facial asymmetry, cleft lip and palate, high arched palate, dental crowding, fusion of primary teeth, dental hypoplasia, malocclusion, and supragingival calculus. CASE REPORT: A 15 year old girl with Fraser syndrome attended Bradford and Airedale salaried dental services complaining of painful mandibular anterior teeth. On examination she presented with hypodontia, shortened roots, and the mandibular anteriors had a titanium trauma splint fixed to reduce the mobility. This had been placed 4 years previously by a paediatric specialist. However oral hygiene was poor around it and therefore the patient had calculus and gingivitis. TREATMENT: The splint was removed followed by subgingival scaling under local analgesia, fissure sealants of all posterior teeth, regular oral hygiene instruction and scaling, and occasional use of chlorhexidine gel. FOLLOW-UP: She has been reviewed regularly with frequent scalings over two years. CONCLUSION: This case reports the possibility of hypodontia and short roots being associated with Fraser syndrome.
