Rev Cubana Pediatr [online]. , vol, n.1, pp Mondini dysplasia is a type of inner ear malformation that is present at birth . Villamar M, del Castillo I, Moreno F. Sensorineural hearing loss and Mondini. Mondini malformation is a historical term used to described incomplete partition type II anomaly with large vestibular aqueduct. Terminology The term is often.

Two boys with clinical signs of VCFS, at the ages of 4. Assimetry of the lateral semicircular canal at left arrows in B. Support Radiopaedia and see fewer ads. New phenotypic alterations of this syndrome have been described in the meantime Abnormal carotid arteries in the velocardiofacial syndrome: Congenital malformations and deformations of ears Q16—Q17 University Diploma in Phonoaudiology. If any doubt it is best to just describe the anatomical abnormalities.
Case 2 Case 2. Unable to process the form. While the hearing loss is sensorineural a conductive element may exist probably because of the third window effect of the widened vestibular aqueduct. From the radiological point of view, oblique reformations with zoom parallel to the stapes are very helpful in detecting mild deformities or incomplete crus.
High-resolution computerized axial tomography of the ear axial and coronal planes evinced the cochlear and vestibular malformation, with tissue of the middle ear communicating directly with the inner dieplasia of the left size at the oval window.
He was born by cesarean, after a week pregnancy. In both, analyses of DNA sample with markers of 22q11 region were performed.
The audiological evaluation shows a conductive hearing loss, with air thresholds around 40 to 50dB HL on the right side and 25 to 30dB HL on the left, with normal bone thresholds, between 0 and 10 dB HL bilaterally. See classification of congenital cochlear anomalies. We consider it to be highly important to carry out a thorough evaluation and monitoring of the hearing evolution, as well as the occurrence of symptoms related to the vestibular function in patients with velocardiofacial syndrome.
Some children may pass newborn hearing screen to lose hearing in infancy but others present with a hearing loss at birth.
This paper underlined the importance of the clinical suspicion of Mondini disease, and the scientific impact of the computerized axial tomography mondoni the temporal bone in order to early diagnose the congenital fistula in the inner ear associated to recurrent bacterial meningitis. He had a minor delay in his motor development and a heart murmur dysfunction that was monitored by a cardiologist. Views Read Edit View history. Hearing loss is often progressive and because of the associated widened vestibular aqueduct may progress in a step-wise fashion associated with minor head trauma.
CT showing bilateral inflammatory otomastoidopathy and a common cavity between the vestibule and the lateral semicircular canal at mondoni arrow inA. Axial and 3-D reconstruction showing displasia of the lateral semicircular canal arrowheads in A and B in comparison with the posterior semicircular canal double small arrows in B and globosity of the vestibule long arrows ds A and B.
The first reference to a primary defect of the ossicular chain was made inin a child with signs of the VCFS and 22q Vestibular function is also often affected.
It is considered that the occurrence of this malformation results from the disruption of disppasia embryonal development on the 7th week of gestation when the cochlear development ceases.
There are only 1. TBX1 is required for inner ear morphogenesis.
How to cite this article. It was also confirmed that she suffered severe neurosensory hypoacusis in her left ear. The other child showed a congenital middle ear malformation with fixation of the malleus on the left annulus tympanicus, and a common cavity bilaterally between the vestibule and the lateral semicircular canal Born by cesarean he developed respiratory infection, hyperbilirubinemia and hypoglycemia in his 4th day of life, treated for 10 days.
He has a third degree cousin from his mother branch, which bears a cleft palate. Otolaryngological manifestations of velocardiofacial syndrome: Velocardiofacial syndrome with facia and pinna asymetries. Sometimes the routine axial images do not show completely the stapes and reformations based on multislice acquisitions are of high quality. Check for errors and try again. Mondini dysplasia associated to recurrent bacterial meningitis-a clinical and imaging correlation. One of them showed a Mondini type cochlear malformation, an abnormal shape of the ossicles, with fusion of the malleus with the incus and a monopodal stapes.
Mondini dysplasia associated to hearing loss and recurrent bacterial meningitis was described in this paper. Please help improve this article by adding citations to reliable sources. The DNA sample analyses from the patient and his parents, with five markers, revealed the delection of, at least, one marker in the 22q Thus, most would favour not using the term, except perhaps in cases where the findings exactly match those described by Mondini.
The oral examination shows a hypoplastic uvula, a short palate with reduced elevation movements. Unsourced material may be challenged and removed. From the radiological point of view, attention should be given to the use of high quality techniques for the tomographic study of temporal bones. He showed a submucous cleft palate, which was operated when he was 2.
