8- Endoscopic Repair for Choanal Atresia
With endoscopes, choanal atresia can be clearly visualized and more precisely repaired. Powered instrumentation with burs, shaving blades and with continuous suction have augmented the technology even further. Under perfect endoscopic visualization, the drilling burs with the continuous suction-irrigation effectively repair the choanal atresia endonasally. The powered endoscopic technique preserves nasal function and avoid damage to neighboring areas e.g. palate. The 300 angled endoscope placed at 12 O'clock with its angle directed inferiorly is the ideal lens to be used. The 4 mm endoscope can be used in almost all patients even in newly-born babies in their first few weeks of age.
Video 27 demonstrates (within PDF file & better download it to your hard disk) the endoscopic technique with the 300 angled, 4 mm endoscope in 11 weeks old newly-born female baby. In addition to the atresia, the nasal bony roof (both fovea ethmoidalis and cribriform plate) has not been developed. MRI study excluded brain herniation into the nose.
