Background: Restenosis and reclosure of the choana are challenging complications after repair of choanal atresia (CA). Modifications to bone drilling with no injury to surrounding nasal soft tissues may reduce postoperative reclosure. Objectives: Our study aims to assess the effectiveness of piezoelectric device in preservation of muco-periosteal flaps and its outcome in reducing postoperative granulation tissue formation and restenosis. Methods: 20 patients with unilateral boney or boney membranous choanal atresia underwent removal of the atretic plate using the piezoelectric device with preservation of the muco-periosteal flap to cover the borders of the neo-choana. Checkup of the cases ranged from 6 months to 2 years duration. Results: 15 patients out of 20 showed patent choana postoperatively and throughout the follow up period with a success rate of 75%. Only 5 patients developed reclosure of the choana with a failure rate of 25%. Conclusion: Results of the study revealed that drilling of boney atretic plate using the piezoelectric device was effective in preservation of the muco-periosteal flap, thus reducing the postoperative granulation tissue formation and reclosure of the choana.
