The atretic plate is generally located at the bony–cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%) the bony canal is involved in a few cases only. The ear has outer, middle, and inner portions. ![]() As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. What is the ear canal The ear canal, or auditory canal, is a tube that runs from the outer ear to the eardrum. The groove between the helix and anti-helix is called the scapha. Deformities of the external ear in the vast majority of cases result from resections of skin cancers (BCC Basal Cell Carcinoma, SCC Squamous Cell. It has an inferior and superior crus that lie either side of the fossa triangularis. The antihelix is a y-shaped region of ear cartilage. The helix is the folded outer edge of the ear. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. The external auditory canal is the opening of the ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. The auricle (pinna) is the visible portion of the outer ear. Various surgical and oncological treatment modalities have been reported. Cerumen, or earwax, is a combination of glandular secretions and desquamated epithelial cells that cleans, protects, and lubricates the external auditory canal. Delayed diagnosis is not uncommon because the symptoms of early tumors are nonspecific. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Malignant tumors of the external auditory canal (EAC) are rare tumors in the head and neck. RESULTS: Acquired stenosis occurs more commonly in males with a male: female ratio of 2–3:1 it seems to be a disorder affecting young adults. MATERIALS and METHODS: In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success. ![]() OBJECTIVE: The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal. IN investigations on the extent to which objective tests can be used to obtain information on the magnitude of the effective amplification hearing aids give. ![]()
