Microtia and congenital aural atresia (CAA) are congenital anomalies that are so common that every otolaryngologist should be familiar with the initial evaluation and care of the patient. When one ear hears normally, speech and language development should be normal. The gross and fine motor development of the baby or child is not expected to be affected in isolated cases of microtia and CAA. Current technologies allow for reconstruction or habilitation of the microtic ear when the child is several years of age. The hope is that tissue engineering can eliminate donor site morbidity. Temporary prosthetic ears will remain an option. Aural atresia work continues to be very dependent on the patient anatomy and the need or desire for better hearing in the affected ear.

Introduction: Despite the reported auditory deficits and developmental challenges in children with unilateral microtia and aural atresia (UMAA), there remains a lack of consensus on early intervention with bone conduction hearing aids (BCHAs) to restore binaural hearing due to the uncertain clinical benefits and intolerability of the conventional devices. Previous studies investigating the auditory benefits under binaural hearing condition were limited and demonstrated controversial opinions in heterogenous patient groups with various devices. Our study aimed to evaluate the audiological performance, including monoaural and binaural hearing, and subjective satisfaction of the ADHEAR system, a novel adhesive BCHA, in experienced pediatric users with UMAA.

Objectives: Implantable bone conduction hearing devices offer excellent auditory rehabilitation. Transcutaneous devices, which use an implanted magnet, are gaining popularity due to higher skin complications associated with traditional percutaneous devices. The Cochlear Baha® Attract System (Cochlear Corporation, Sydney, Australia) is a transcutaneous device and is regarded as a passive transcutaneous implant.

Background: Congenital aural atresia (CAA) is a complex condition that can present in various forms, including Schuknecht type B stenosis, characterized by a congenitally narrow bony external auditory canal (EAC). This study aims to evaluate the long-term surgical outcomes of canal-tympanoplasty in patients with CAA Schuknecht type B.
Methods: The study included 21 ears diagnosed with CAA Schuknecht type B that underwent canal-tympanoplasty.
