A 15-day-old female newborn presenting nasal obstruction since birth underwent computed tomography of the paranasal sinuses in our department due to clinical suspicion of choanal atresia. The patient presented no other complaints. Computed tomography () allowed the diagnosis of pyriform aperture stenosis, which is a rare cause of nasal obstruction in neonates and was first described in 1989.() Pyriform aperture stenosis becomes particularly significant during the first two months of life when infants are mandatory nose breathers.

ABSTRACT Technical advances in magnetic resonance imaging have allowed to accurately detect and grade endolymphatic space distension in Ménière disease; this was only possible in post-mortem histological studies until a few years ago. Magnetic resonance imaging rules out other causes of vertigo and hearing loss, and is able to evaluate the cochlear and vestibular compartments of the endolymphatic space using a dedicated protocol.
