Choanal atresia may be membrane of bony, unilateral or bilateral. Approximately 90%
of the choanal atreus are bony type. Unilateral choanal atresia often eludes the diagnosis
because of the absence of subjective symptoms in the neonatal period.
However, bilateral choanal atresia presents at birth with cyclic respiratory distress
aggravated by feedings. so complete bilateral choanal atresis is considered as a neonatal
emergency. Examinations for the diagnosis of chonal atresia include 1) attempt at
passing a rubber catheter of probe through the patient's nose. 2) mirror examination of
the nasopharynx, 3) digital examination of the nasopharynx, 4) X-ray examination after
installation of radiopaque materal into the nasal cavity. But, computed tomography has
become accepted method for evaluation of choanal atresia
Surgical repair of choanal atresia is accomplished via transpalatal of transpalatal
approach. Advantages of the transpalatal approach are improved exposure and the
preservation of mucosal flap along the newly formed apertures. On the other hand, the
transpalatal approach carries the risk of injury to the greater palatine neurovascular
complex, and requires longer operative time.
Arter careful physical and radiographic examinations, we accomplished the surgical
repair of the complete bony bilateral choanal atropia via transpalatal approach without
complications.
