A series of 65 cases of choanal atresia seen in 19 years is reviewed. We use a wisp of cotton fiber held under the nose and a plastic catheter passed into each nasal cavity to test nasal patency. Horizontal computerized tomography is confirmed as the radiological study of choice, and a standard endoscopic technique used during surgical correction is described.

AbstractChoanal atresia is a developmental anomaly where there is failure of communication of the nasal cavity to the nasopharynx. The atresia can be membranous or bony in nature, but may be mixed as is seen in most of the cases. Bilateral choanal atresia is an emergency condition and newborns can have severe respiratory distress and cyanosis at birth. Failure to pass an 8 F catherter through the nasal cavity more than 5.5 cm from the alar rim points to the presence of choanal atresia. In emergency, bilateral choanal atresia is managed with an oropharyngeal airway. Flexible nasal endoscopy and CT scan can confirm the diagnosis of choanal atresia. Surgery is the definitive treatment which can be done either by transnasal or transpalatal approach. The transnasal endoscopic route is currently the preferred procedure and can be performed as a minimally invasive procedure. This has less complications and a high success rate. We studied four cases of unilateral choanal atresia presented to our hospital, with respect to the etiological factors, clinical features and management.

Although the most common form of nasal obstruction in neonates is soft tissue edema, congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. In addition to the well described choanal atresia, CT imaging of the newborn in respiratory distress reveals two other forms of bony nasal cavity deformities: nasal pyriform aperture stenosis and nasal cavity stenosis. All of the three types of bony nasal cavity deformities have characteristic anatomical features, are associated with distinctive congenital anomalies, and are postulated to have differing embryological causes. Five patients with congenital bony nasal cavity deformities are presented. These cases illustrate the clinical and radiological presentation of varied types of congenital nasal cavity obstruction as well as the criteria used to guide clinical management.

Acoustic rhinometry is a recently developed method for the objective assessment of nasal patency. In this study, acoustic rhinometry was used to measure changes in nasal cavity dimensions in the immediate response to nasal allergen challenge in eight pollen-sensitive subjects. Acoustic rhinometric changes were compared with subjective symptoms, as well as histamine in nasal secretions, cytology of nasal mucosal scrapings, and changes in olfactory function. A significantly greater decrease in nasal airway caliber occurred following allergen challenge as compared to buffer diluent challenge in the same individuals (70% ± 1% versus 22% ± 5%). During an allergic response, a strong correlation was found between the minimum cross-sectional area and the volume of the nasal cavity measured by acoustic rhinometry (r = .9). However, no correlation was observed between nasal airway caliber and concomitant subjective congestion reported by the subjects. Amodest decrease in olfactory function was seenfollowing allergen challenge (3.1 ± 1.4 fewer odors identified correctly out of 20; p = .08). However, the alterations of olfactory function did not correlate with changes in nasal patency. The results presented in this study demonstrate that acoustic rhinometry has great potential as a reproducible method for the objective assessment of nasal obstruction occurring in nasal allergen challenge studies.

Choanal atresia (CA) is a rare, congenital malformation resulting as a failure incommunication between the posterior nasal cavity and the nasopharynx. The clinical course isoften asymptomatic in unilateral CA leading to higher rates of misdiagnosis, in comparison tobilateral CA, which manifests itself as a surgical emergency at birth. Most cases present asisolated malformations, but it may also be associated with other congenital anomalies in 20-50%of cases. Currently, the most important diagnostic tool for CA is computerized tomography (CT)and confirmatory diagnosis is usually achieved with the help of nasoendoscopic examination.Although, different surgical approaches have been used in the past, transnasal endoscopicrepair is currently preferred over others. Herein, we describe our experience of three cases andshare our simple stentless endoscopic technique, to facilitate physicians working in low facilityunits for a timely diagnosis and prompt treatment.
