[Congenital choanal atresia].

In 1990-1995 the authors treated 40 children (age 1 month to 12 years) with congenital choanal atresia (CA). Bilateral CA occurred in 4, unilateral in 36 children. Complete and incomplete CA were diagnosed in 37 and 3 patients, respectively.

[Neurosensory hearing loss in children with acute and chronic otitis media diagnosed by the measurement of short-latency auditory evoked potentials].

The sensory component of acute otitis media, especially in children, has been poorly studied. In order to identify the importance of ERA for the diagnosis of the neurosensory component of hypoacusis associated with acute otitis media, we examined 56 children. In all the patients ERA were recorded, and in children over 3 years old tonal audiometry was performed.
