Omura K, et al. - Researchers elucidated their surgical technique designed to minimize bone exposure while maximizing the frontal neo-ostium area created with Draf type II and III procedures. The lacrimal sac was fully exposed and used a superior lateral anterior pedicle flap to cover the exposed bone during the Draf procedure. Findings suggested the Draf type II and III procedures with lacrimal sac exposure and a superior lateral anterior pedicle flap to be convenient and effective. In all patients, the neo-ostium remained patent. Researchers did not note any complications, such as synechiae or orbital injury in any of the patients.
