Patients with microtia and congenital aural atresia should have a comprehensive hearing assessment early in life. Options for hearing habilitation should be presented, and children with bilateral aural atresia should be fitted with a bone conducting hearing device to support normal speech and language development. If atresia surgery is pursued, the microtia surgeon must be aware of certain principles. This article presents recommendations on options for potentially improving hearing in children with congenital aural atresia: assessing surgical candidacy; chronology and timing of surgeries; functional importance of certain ear structures; and understanding the possible locations of an aberrant facial nerve to avoid injury in these patients...

OBJECTIVES: Congenital Aural Atresia (CAA) is a deformity of the external ear and it is commonly associated with malformations of middle and inner ear and, in some cases, with other facial deformities. Very few assessment measures exist for evaluating the functional impairment in children with CAA. Purpose of this study is to introduce and describe an assessment Checklist, (nominated FOS Checklist) that covers feeding abilities (F), oralmotor skills (O), communication/language development (S) in children with CAA...

OBJECTIVE: To compare temporal bone thickness along a three-dimensional arc of potential osseointegrated implant sites for bone-anchored hearing aids in children with and without aural atresia using computed tomographic imaging (CT). STUDY DESIGN: Retrospective case review. SETTING: Tertiary children's hospital. PATIENTS: Children with or without aural atresia aged less than 11 years who had a temporal bone CT. INTERVENTION (S): Calvarial bone volume on CT was rendered in three-dimensional and thickness was reconstructed and measured at up to 12 defined sites along an arc of recommended implant sites...

Acquired atresia of External Auditory Canal (EAC) is seldom encountered in routine otolaryngology practice. Apart from resulting in moderate-to-severe conductive hearing impairment, it is a potentially dreaded condition which might lead to canal cholesteatoma. Suspected to develop as a consequence of a pre-existing chronic otitis externa/media, the EAC atresia leads to proximal (medial) accumulation of desquamated epithelium and denatured keratin (the canal cholesteatoma) that further leads to aggravation of the chronic otitis, thereby initiating a vicious cycle...

OBJECTIVES: Our aims were to measure and compare anatomical parameters of the ossicles in normal, congenital aural stenosis (CAS), and congenital aural atresia (CAA) ears. METHODS: This retrospective study was performed using three-dimensional reconstructed images derived from computed tomography scans of 20 normal subjects, 20 CAS patients, and 20 CAA patients. RESULTS: The lengths of the malleus handle and long process of the incus were greater in normal ears than in CAS and CAA ears (all P < 0...

OBJECTIVE: To investigate the deformations of temporal bone and mandible combined with congenital aural atresia. METHODS: A total of 158 patients with congenital aural atresia were included in the study. The raw CT data of the temporal bone was imported into MIMICS v 12 and threshold dissection, region growing and three-dimensional (3D) calculation were used to calculate 3D models. The 3D characteristics of the temporal bone and upper part of mandible were assessed...

Microtia is a congenital auricular deformity that commonly presents with associated congenital aural atresia. The most acute concern in these patients is concomitant hearing loss at birth. A team-based approach by plastic surgeons and otologists is necessary to address both the otologic and audiologic concerns of microtia and atresia. Hearing rehabilitation is imperative; yet it should not compromise the aesthetic components of reconstruction and vice versa. Here, the authors propose a framework to evaluate and manage patients with microtia and atresia with the goal of optimizing functional and cosmetic outcomes...

OBJECTIVES/HYPOTHESIS: We hypothesized that children with isolated nonsyndromic unilateral congenital aural atresia have subclinical mandibular condylar hypoplasia ipsilateral to the atretic ear, and that the Jahrsdoerfer score is associated with the degree of condylar hypoplasia. STUDY DESIGN: Retrospective self-controlled case series. METHODS: We reviewed high-resolution computed tomography scans of the temporal bones of 68 children with isolated nonsyndromic unilateral congenital aural atresia...

OBJECTIVES/HYPOTHESIS: We aim to define the frequencies of anomalies of the inner ear, oval window, and round window ipsilateral to isolated non-syndromic unilateral aural atresia. METHODS AND MATERIALS: Retrospective case series. We reviewed high resolution computed tomography scans of the temporal bones of 70 children with isolated non-syndromic unilateral congenital aural atresia. Scans were reviewed according to the Jahrsdoerfer criteria and further evaluated for anomalies of the vestibule, semi-circular canals, cochlea, internal auditory canal and vestibulocochlear nerve...

Fusion of the atlas with the occipital bone is a rare congenital dysplasia known as occipitalization of the atlas, occipitocervical synostosis, assimilation of the atlas, or atlanto-occipital fusion. It is a component of the paraxial mesodermal maldevelopment and commonly associated with other dysplasias of the craniovertebral junction. External auditory canal atresia or external aural atresia is a rare congenital absence of the external auditory canal. It occurs as the consequence of the maldevelopment of the first pharyngeal cleft due to defects of cranial neural crest cells migration and/or differentiation...

OBJECTIVE: To demonstrate the surgical technique and audiological results of a middle ear implant for restoring hearing in patients with bilateral aural atresia and microtia with conductive or mixed hearing loss. MATERIALS AND METHODS: In this prospective study, 12 subjects aged 12 years and older presenting with hearing loss and bilateral congenital aural atresia underwent surgical insertion of a middle ear implant. The patients underwent tympanomastoidectomy with a wide opening of the attic and preservation of the roof of the atresic tympanic bone to expose the middle ear and position the floating mass transducer of the implant...

CONCLUSION: Each of eight patients with bilateral microtia and atresia underwent bilateral reconstruction of the auricles and external auditory canals and were fitted bilateral canal-type hearing aids in the operated ears to replace a bone conduction hearing aid. The ability to discriminate inter-aural intensity difference (IID) and even inter-aural time difference (ITD) was retained in all these patients. OBJECTIVE: This study studied the post-operative sound lateralization ability of patients with bilateral microtia and atresia after total reconstruction of both auricles and external auditory canals, followed by fitting of bilateral canal-type hearing aids...

BACKGROUND: Deletions of the long arm of chromosome 18 cause a common autosomal syndrome clinically characterized by a protean clinical phenotype. CASE PRESENTATION: We report on a 16-month-old male infant affected by fever attacks apparently unrelated with any infectious or inflammatory symptoms, growth retardation, bilateral vertical talus, congenital aural atresia, dysmorphisms, mild psychomotor delay, and peculiar neuroradiological features. Array-CGH analysis revealed one of the smallest 18q22...

Microtia reconstruction is a challenging endeavor that has seen significant technique evolution. It is important to educate patients and their families to determine the best hearing rehabilitation and ear reconstructive options. Microtia is often associated with aural atresia, hearing loss, and craniofacial syndromes. Optimal care is provided by multiple disciplines, including a reconstructive surgeon, an otologic surgeon, an audiologist, and a craniofacial pediatrician. Microtia management includes observation, prosthetic ear, autologous cartilage reconstruction, or alloplastic implant placement...
