Flap suturing endonasal dacryocystorhinostomy assisted by ultrasonic bone aspirator.

Acta Otolaryngol 2022 Mar-Apr;142(3-4):316-322. Epub 2022 Apr 5.

Department of Ophthalmology, University of Toyama, Toyama, Japan.

Background: In the external dacryocystorhinostomy (DCR), a sutured anastomosis technique performed between the nasal mucosal and lacrimal sac flaps reported by Dupuy-Dutemps and Bourguet was the gold standard and was believed to lead to the success of the surgery. However, because of the small working space, a flap suturing technique has not been completely established in endonasal DCR (END-DCR).

Objectives: The effect of the modified flap suture anastomosis technique using a Sonopet ultrasonic bone aspirator was retrospectively compared to that using a diamond burr in patients with nasolacrimal duct obstruction. Read More
