King Abdulaziz Medical City, Kingdom of Saudi Arabia
Introduction: Choanal atresia (CA) is the developmental failure of the nasal cavity to communicate with nasopharynx. The definitive treatment is surgical, and different surgical techniques and approaches are used. We describe our experience in treating CA using new entity, Omni guide co2 laser.
Material and methods: We retrospectively evaluated 7 patients with CA operated in our Institute in King Abdulaziz Medical City in Riyadh from 2012 to 2014.
Results:. Bilateral presentation was 4 cases and unilateral was 3 cases . OmniGuide co2 laser used in two cases (1 case 3 times). Revision from 1 month to 1 year after first operation with OmniGuide co2 laser . Revision rate with OmniGuide co2 laser 100% . All revsion cases (5 cases) balloon dilation was used, if restonsosis memembrane (granulation tissue) but if restenosis fibers tissue the microdebrider was used.
Conclusion: using Omni Guide co2 laser does not decrease the rate of revision & it is expensive device.
