[Results of the surgical management of congenital malformations of the external auditory canal and of the middle ear in children with special reference to vein xenografts].
The paper deals with the possibility of surgical reconstruction of congenital malformations of the ear, the choice of a proper surgical method with the utilization of calf-vein xenografts, and with postoperative effects of the employed operative technique modified by the authors. The research material comprised 70 children between 3 and 17 years of age treated in years 1992-1995. Reconstructive surgery was performed in 24 children (29 ears). Calf-vein xenografts were used for myringoplasty and for the lining of the bony walls of the postoperative cavity (of the created external auditory canal and of the mastoid cavity). Hearing improvement was gained in 79% of cases, and in 55% of patients it was 24 dB or higher. Patent and epithelilized external auditory canals were obtained in 81% of the operated "atretic" ears. Failures referred to fibrodermal restenosis and lack of hearing improvement. Surgical treatment of bilateral congenital aural "atresia" can be performed in children at 4-6 years of age. Vein xenografts are a good reconstructive material recommended in congenital aural malformations for myringoplasty and canaloplasty.
