Midnasal stenosis: A rare differential diagnosis to choanal atresia
Authors
We report on a male neonate with the very rare malformation of congenital midnasal stenosis (MNS). Immediately postpartum the child developed paradoxical cyanosis with recurrent cyanotic episodes in the near absence of nasal breathing. After exclusion of the most common causes, such as choanal atresia and congenital stenosis of the piriform aperture, the diagnosis of MNS was confirmed by nasal endoscopy and computed tomography. Since conservative therapy by means of local decongestant nasal spray and inhalations with epinephrine did not result in any improvement, surgical treatment was performed. After a dilatation and a tamponade attempt, bougienage of the inferior and middle nasal passages including the placement of bilateral stents made of modified endotracheal tube were performed on the 17<sup>th</sup> day of life, which resulted in sustained improvement of symptoms after an operative revision after 5 days. As the symptomatology and the food intake improved markedly during the course, removal of the nasal stents on day 37 of life revealed sufficient respiration and a persistent quiet breathing pattern without signs of dyspnea. In the follow-up examination after three months any respiratory abnormalities could not be observed. The infant was completely orally fed and thrived adequately.
