“…Its incidence has been estimated at 0.6 cases per 100,000 [1] . It has different names in literature such as post-inflammatory medial meatal fibrosis [2,3] , post-inflammatory medial canal fibrosis [4] , post-inflammatory acquired atresia [5] , canal atresia [6] , and stenosis of the external auditory canal [7] . The term canal stenosis has often been used to describe cases of acquired atresia; however, these are two separate entities.…”

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. 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. 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. 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. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. 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. Preserved healthy canal skin, split-or full-thickness skin grafts, or pre-or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred. CONCLUSION:The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.

The aim of this study was to investigate the aetiology of acquired atresia and stenosis of the external auditory meatus and to present our results for surgical management. Over an 18-year period (from 1986 to 2004), data were collected prospectively from patient cohorts in Dundee and Edinburgh. Stenosis of the auditory meatus was due to chronic otitis externa in 64 per cent of cases, compared with 37 per cent of cases with acquired atresia; the latter had instead a history of chronic suppurative otitis media in 43 per cent. Surgical treatment of canal stenosis with meatoplasty alone achieved a widely patent ear canal in 80 per cent of cases, with 78 per cent of ears remaining free of discharge. Cases of acquired atresia treated with simple surgical excision of the soft tissue plug experienced a 100 per cent failure rate. The additional use of a split skin graft achieved a patent meatus in 70 per cent of cases, with hearing improvement in 79 per cent. However, the ear canal remained unstable and late recurrence was observed.

“…В среднем хорошие анатомические результаты после операции по устранению приобретенной атрезии НСП составляет примерно 60%, тогда как частота рецидивовприблизительно 20% [3,8,18,19,24,35,41,[49][50][51]. Независимо от примененного хирургического метода рецидив, по данным разных авторов, может наблюдаться через 6 мес [19], 3 года [22,23] и 9 лет [23], но в основном повторное формирование атрезии происходит в течение первого года после операции [2,29,52].…”

Характер перенесенных оперативных вмешательств может быть различен: тимпанопластика, удаление экзостозов НСП, неудачное устранение врожденной атрезии НСП [26].…”

Acquired atresia of the external acoustic meatus is a rare pathological condition characterized by obliteration of the medial part of the external acoustic canal by a soft fibrous plug. The present article presents an overview of a series of cases of acquired atresia and stenosis of the external acoustic meatus with the description of etiology, pathogenesis, and methods for the treatment of this condition. In the majority of the cases, atresia develops at the final stage of granulation external otitis with or without an accompanying dermatological pathology. Another common cause of the acquired atresia of the external acoustic meatus is the fracture of the temporal bone as well as extensive ear surgery, radiation therapy and a neoplasm in the auditory passage. The surgical strategy for the management of the acquired atresia and stenosis of the external acoustic meatus consists, besides the excision of the fibrous plug, of the application of the cutaneous flaps and/or transplants to cover the bare parts of the bone portion of the affected external canal. In spite of such treatment, the state of the external acoustic canal remains unstable, and a relapse of its atresia and stenosis can not be wholly excluded.
