[Obstructive sleep apnoea syndrome in children].

Obstructive sleep apnoea syndrome is a well-known clinical entity in adults but until now it has been less well studied in children. In recent years there has been a dramatic increase in the recognition of sleep disorders in children. Our goal is to analyze scientific data published in the last few years.

Otorhinolaryngologic manifestations in Chiari malformation.

The Chiari malformation causes herniation of the cerebellar amygdalae through the foramen magnum, resulting in the descent of the brain stem and/or traction on the lower cranial pairs. It is important for otolaryngologists to recognize Chiari malformations as part of the differential diagnosis of balance disorders, because patients may initially exhibit symptoms related to the vestibular system, including ataxia, nystagmus, or vertigo. We report 2 cases.
