“…To provide better care for CA in newborns, it is critical to segregate the different possibilities of nasal obstruction. At birth, nasal obstruction may be related to neonatal rhinitis, rhino-septal deviations due to obstetric trauma, nasal dysgenesis (stenosis of the piriformis orifice anteriorly, stenosis of the nasal aperture in the middle part, and CA posteriorly), cerebral malposition (meningoceles and meningoencephaloceles), congenital endonasal masses (nasolacrimal cysts, dermoid cysts, nasal hemangiomas), embryonic tumors, or arhinia [5,6]. With an estimated incidence of 1/5000 and 1/7000 births, CA is more rarely bilateral and may sometimes be part of a polymalformative framework, the most frequent of which is CHARGE (colobomas, cardiac (heart) defects, choanal atresia, retardation of growth and cognition, genitourinary anomalies, and ear anomalies) syndrome [1,4,[6][7][8].…”

Bilateral choanal atresia is a surgical emergency because of the risk of neonate death from acute asphyxia if treatment is delayed. Its diagnostic confirmation is often endoscopic or CT scan and requires a search for associated malformations.We present the case of a nine-year-old girl who was referred to the ENT department with suspected adenoid pathology. Her medical history showed respiratory distress at birth treated as a neonatal infection. We suspected bilateral choanal atresia due to the absence of fogging on mirror test and failure to pass a 6Fr or 8Fr suction catheter through the nasal cavity into the nasopharynx. Facial CT confirmed the presence of bilateral mixed osteo-membranous choanal atresia. Transpalatal choanoplasty was successfully performed with pre and postoperative endoscopic examination. This clinical case adds to the limited literature on bilateral choanal atresia diagnosed long after birth, raising once again the lack of knowledge of choanal atresia by some health workers, emergency neonatal care, the mechanism of breathing in the newborn, and the management of this malformation. Transpalatal choanoplasty is a good alternative when technical conditions do not allow an endoscopic endonasal approach.

“…Congenital nasal obstructions are generally classified according to their anatomical location as anterior, midnasal and posterior. 1 The most common posterior type (1 in 5000 to 8000 births) and the most severe congenital nasal obstruction is choanal atresia, followed by pyriform aperture stenosis anteriorly (1 in 25 000 births). [1][2][3] Congenital midnasal stenosis has been previously described as a component of many syndromes, but it was first reported precisely in 2004 by Raghavan et al 4 Case series have subsequently been presented, and diagnosis and treatment modalities have been discussed in the literature.…”

Midnasal stenosis in adults with normative values

Background Congenital midnasal stenosis has previously been described as a cause of nasal obstruction in infants, and conservative and interventional treatments have been suggested. However, midnasal stenosis in adults has not been reported and related normative measurements have not been studied. Methods Three adult patients presented with nasal obstruction and, based on examination and radiological findings, were diagnosed with midnasal stenosis. Anatomical measurements were studied in axial and coronal computed tomography scans, and compared with findings for 161 healthy individuals. Results Anatomical measurements showed that the endonasal cavity was larger in males than females. The midnasal region was found to be constricted in patients compared to healthy controls. Conclusion This is the first study to report on midnasal stenosis in adults and to define normative anatomical measurements in adults. In patients presenting with nasal obstruction, midnasal stenosis should be suspected during endoscopic visualisation of medially located middle turbinates and uncinate processes in nasal cavities. A definitive diagnosis of midnasal stenosis can be made by examining paranasal sinus computed tomography scans. Endoscopic middle turbinectomy, complete uncinectomy, mega maxillary antrostomy and partial anterior ethmoidectomy have been suggested to relieve midnasal stenosis.

“…Die Engstelle bei einer mittleren nasalen Stenose ist laut Syed et al auf ein ungleiches Wachstum der seitlichen Nasenwand oder eine übermäßige Faltung der Nasenscheidewand zurückzuführen [6]. Laut Sohal et al kann die mittlere nasalen Stenose durch eine angeborene Verdickung der Nasenscheidewand oder eine knöcherne Verengung der Nasenhöhle selbst entstehen [7]. Die Engstelle liegt zwischen dem Nasenseptum und der unteren Nasenmuschel [8].…”

In diesem Beitrag berichten wir über ein männliches Neugeborenes mit der sehr seltenen Fehlbildung einer angeborenen mittleren nasalen Stenose (engl.: midnasal stenosis; MNS) im Rahmen einer Deletion-Duplikations-Mutation auf Chromosom 7. Nach Ausschluss der häufigsten Ursachen rezidivierender zyanotischer Episoden, vor allem während der Nahrungsaufnahme, wurde mittels nasaler Endoskopie und einer Computertomografie die Diagnose einer MNS gestellt. Da die konservative Therapie keine Besserung erbrachte, erfolgte die operative Behandlung im Sinne einer Bougierung des unteren und mittleren Nasenganges einschließlich des Einsetzens von beidseitigen Stents, die zu einer anhaltenden Besserung der Beschwerden führte.
