Trans-nasal endoscopic holmium: YAG laser correction of choanal atresia.

ABSTRACT

Five patients with choanal atresia were treated, using a trans-nasal endoscopic HolmiumYAG laser. The age of patients ranged from 15 months to 53 years. The nasal endoscope provides excellent visualization. The advantage of the HolmiumYAG laser is its fibre-optic delivery, allowing the laser to be hand-held, giving greater precision. Good nasal airways were achieved in four out of five cases with a single treatment. The procedure was found to be safe, quick, with minimal morbidity and a shorter in-patient stay.
