Technique for fabrication of splint preventing postsurgical restenosis in choanal atresia

The Effectiveness of Local Gentamicin and Dexamethasone Drops in Posterior Choanoplasty

“…3 Most authors agree with the use of a stent for any surgical approach, although exact duration is still controversial, ranging from 4 months 15,16 to 2 days. 17 Schoem et al 3 was able to show by experience that stenting was not necessary for the successful repair of both unilateral and bilateral CA. This author attributes high success rates without stenting to the evolution of the transnasal approach.…”

Atresia de coana: análise de 16 casos - a experiência do HRAC-USP de 2000 a 2004

“…In all our patients submitted to transpalatal technique, a stent was used during an average period of 2 months. Most authors agree with the use of a stent in transpalatal surgeries, although permanence time is still controversial, showing a range of 3-4 weeks 11,12 to 2 days 13 . Despite the fact that the permanence time adopted by our service is longer than that discussed in the literature, none of the patients presented adverse events due to this issue.…”

A Simplified Approach of Customized Acrylic Nasal Stent Fabrication

“…A number of materials are used for this purpose, which include ribbon gauze (Clauden nasal ribbon gauze; Lohmann Technologies Corp, Hebron, Kentucky, USA), fingerstall packing (Rhinotamp; Vostra, Aachen, Germany), cellulose packs (Surgicell; Johnson & Johnson Medical, Arlington, Texas, USA), foam packs (Gelfoam; Mallinckrodt Baker Inc, Phillipsburg, New Jersey, USA), catheters (Ethmo Ballooncatheter; Spiggle & Theis, Dieburg, Germany) and Argyle nonconductive connective tubing (Argyle, Division of Sherwood Medical, St Louis, Missouri). [3][4][5][6][7][8] These materials keep the wound surfaces apart, prevent formation of hematoma and prevent restenosis due to scarring. Eventually, epithelization occurs around them, securing the long-term patency of the surgically established airway.…”
