Surgical treatment of congenital aural atresia – is it still justified?

Abstract

For 90% of the patients in group 1 and 79% of the patients in group 2, the postoperative ABG was within 0 and 30 dB. The most common complications were recurrent infection, lateralization of the tympanic membrane, and restenosis of the ear canal.

Middle ear abnormalities in Van Maldergem syndrome

“…Sometimes the inner ear can be affected too [Schuknecht, ]. Overall, patients with unaffected middle ear and hearing ossicles, have best surgical outcomes [Cremers et al, ; Schuknecht, ; Jahrsdoerfer et al, ; Oliver et al, ; Edfeldt and Strömbäck, ; Moss et al, ]. The patient presented here had a total bony atresia over part of the external meatus, resembling a type IIA aural atresia in the Altmann–Cremers classification [Cremers et al, ].…”

Long-term results of atresiaplasty in patients with congenital aural atresia

“…The average number of hospital admissions during the first postoperative year was 10 (range [5][6][7][8][9][10][11][12][13][14][15][16][17] per patient. At the end of the follow-up, the cumulative number of visits was 21 (range 7-39).…”

“…Moreover, in 12 patients, the mean postoperative PTA was 18 dB HL better than preoperatively [6]. Edfeldt et al (2015) reported that over 80% of their 100 atresia patients obtained an ABG less than 30 dB HL. Nadaraja et al (2013) performed a systematic review to compare the hearing results of atresia surgery and osseointegrated bone conduction device in CAA patients [11].…”

“…In our study, only three patients (21%) -those with a stenotic ear canal -had a postoperative PTA of 30 dB HL or less -i.e. a result that could be considered successful [12].…”

The interdisciplinary approach to the rehabilitation of the patients presenting with congenital atresia of the external auditory canal and the concomitant microtia

“…Ряд авторов предлагают использовать передний доступ; при этой технике создание трепанационной полости борами начинают в области предполагаемой проекции наружного слухового прохода отступя от височно-нижнечелюстного сустава и ниже уровня средней черепной ямки. Наиболее распространен трансмастоидалный доступ с широким вскрытием антрума и аттика, который позволяет минимизировать такие послеперационные осложнении, как рестеноз канала, инфицирование среднего уха и повреждение лицевого нерва [20,21].…”
