Abstract
Objectives To systematically review the literature to evaluate the indications, safety, and efficacy of the Draf IIb procedure and to evaluate the added advantages of technical factors such as stents and flaps. Data Sources Articles published until July 2019 on Medline and Cochrane databases. Review Methods After a systematic review based on the 2018 PRISMA guidelines was conducted, 26 of 1533 articles were included and reviewed for indications of Draf IIb; surgical technique; use of flaps, stents, grafts, or mitomycin; complications during and after surgery; and success or recurrence rate. Results The main indication for Draf IIb was chronic frontal rhinosinusitis (61.82%). The postoperative patency rate was 87.85%. When flaps/grafts were applied, the rate was 93.5%, but their added value was not statistically significant. Stents could be an alternative for revision surgery. Treating frontal pathologies other than chronic rhinosinusitis was also satisfying. Safety was comparable to Draf III: no perioperative complications were reported, only a few postoperative ones (eyelid ecchymosis and periorbital cellulitis in 0.2% of the cases, hyposmia in 1.55%). Conclusion When properly indicated, Draf IIb frontal drilling is a safe and highly effective surgical technique for frontal pathology treatment, with efficiency and safety comparable to the Draf III, making it a valid option when a bilateral approach is not needed. More studies are required to confirm the added values of flaps, grafts, and stents.
