“…2 Surgical treatment options include balloon dilatation, lateralisation of the inferior turbinates, and nasal stent placement for a few days to weeks. 4,6 The key point is not to damage the mucosa during surgery. The aetiology and treatment of adult midnasal stenosis differ from that of newborns.…”

“…[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. [5][6][7][8] Choanal atresia, pyriform aperture stenosis and midnasal stenosis are clinically similar entities. Endoscopic evaluation plays an important role in diagnosis.…”

“…Congenital midnasal stenosis should be considered in an infant if the middle turbinate is not visible with a fibre-optic endoscope after passing the anterior end of the inferior turbinate, despite no severe septal deviation. 6 Levi et al have established diagnostic principles of clinical examination and computed tomography (CT) findings in newborns with midnasal stenosis. These authors have determined comprehensively the normative measurements of neonatal endonasal anatomical distances related to midnasal stenosis.…”

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.

“…In der Literatur wurde keine Inzidenz beschrieben. 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].…”

“…Dies wurde bereits von Syed et al als mögliche Komplikation beschrieben. Andere Komplikationen bei längerfristiger Stentimplantation sind Stentmigration, Stentbruch, Granulationen, Infektionen, Ulzerationen, sowie Nekrosen und nachfolgende Stenose im Bereich der knorpeligen Anteile der nasalen Weichteile [6].…”

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.
