The aural atresia surgery follows the microtia repair to allow for a best cosmetic reconstruction. While surgery can be performed earlier it is usually recommended that patients wait until between ages 8-10, when sufficient rib cartilage can be obtained to create an ear that is closer to its adult size. Aural atresia results in conductive hearing loss, with normal inner ear function (as the inner ear has a different embryological origin, it is normally. Once it is established that the hearing in the inner ear is intact by audiometric testing, and high resolution CT scan determines that the middle ear configuration is amenable to successful surgical reconstruction of the external ear canal and middle ear, surgical repair for aural atresia may be an option to restore hearing.Īuricular (microtia) reconstruction surgery can improve the visual appearance of the outer ear and surgical repair of the atresia or BAHA bone-anchored hearing aid restores hearing. Frequently amplification with hearing aids or bone conduction devices ( BAHA), are utilized before aural atresia surgery is performed. Dr Hammerschlag is co-director of the Congenital Ear Development Anomalies Center at the Institute of Plastic and Reconstructive Surgery, New York University Medical Center, where aural atresia and microtia (are treated.Īuditory Testing is necessary to determine the extent of the condition’s impact on hearing for initial management for hearing loss, especially in the infant. This may also include deformation or lack of middle ear bones (auditory ossicles). Frequently, these patients are best evaluated by an experienced multi-discipline craniofacial team, which includes a plastic surgeon, otologist (ear surgeon), orthodontist, and nurse coordinator. Congenital Aural Atresia is a medical condition resulting in underdevelopment of the ear canal, causing hearing impairment. Aural atresia and microtia can be the only manifestation of hemifacial microsomia or present along with other parts of this syndrome, such as incomplete jaw development. It is frequently associated with incomplete development or absence of the outer ear (auricle), a condition known as microtia.Īural atresia (absence of ear canal, middle ear) and microtia (malformation of auricle) are part of a congenital syndrome involving variably incomplete development of the side of the face, called hemifacial microsomia. J Int Adv Otol 2019 15(2): 204-8.Aural atresia is a congenital malformation in which the ear canal and the middle ear are underdeveloped or even absent. International Consensus Recommendations on Microtia, Aural Atresia and Functional Ear Reconstruction. Many of the following publications contain the latest genetic research on Microtia and Aural Atresia. Patients with microtia and aural atresia can be guided by the consensus recommendations provided herein.Ĭite this article as: Zhang TY, Bulstrode N, Chang K, Cho YS, Frenzel H, Jiang D, et al. Recommendations include the definition and classification of microtia/atresia, treatment of microtia, treatment of congenital aural atresia, flowchart of functional ear reconstruction, and future research directions. The consensus recommendations reported herein take into account the variability in practice patterns present among experts in the field the degree of consensus was quantified by presenting the percentage of above authors who agree or partially agree with each statement. The initial testing for Aural Atresia, Congenital CAA can begin with facial genetic analysis screening, through the FDNA Telehealth telegenetics platform, which can identify the key markers of the syndrome and outline the type of genetic testing needed. The methods are expert opinion from the members of the International Microtia and Atresia Workgroup (IMAW). How does someone get tested for Aural Atresia, Congenital CAA. These deformities are often associated with ossicular chain malformations 2. The degree of external auditory canal (EAC) deformity varies from complete absence to mild stenosis, with a small tympanic membrane. All patients with microtia and external auditory atresia should be seen in the setting of a multidisciplinary team and agreed treatment outcomes should be measured, so that techniques, approaches, and results can be compared. Congenital aural atresia (CAA) causes moderate to severe hearing loss, usually conductive or mixed type 1. The aim of this report is to provide international recommendations for functional ear reconstruction in patients with microtia and aural atresia.
