CHOANAL ATRESIA

DIAGNOSIS AND SIMPLE ENDOSCOPIC REPAIR AT REMOTE PRIMARY CARE CENTERS

Abstract

Choanal atresia (CA) is a rare, congenital malformation resulting as a failure in
communication between the posterior nasal cavity and the nasopharynx. The clinical course is
often asymptomatic in unilateral CA leading to higher rates of misdiagnosis, in comparison to
bilateral CA, which manifests itself as a surgical emergency at birth. Most cases present as
isolated 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 endoscopic
repair is currently preferred over others. Herein, we describe our experience of three cases and
share our simple stentless endoscopic technique, to facilitate physicians working in low facility
units for a timely diagnosis and prompt treatment.
