Location of stenosis at preoperative visit and intraoperative probing was recorded, and during follow\u2010up, recurrence of stenosis prompting additional surgery and complications were noted. Survival analysis was applied to compare reoperation rate depending on site of stenosis.

Canaliculodacryocystoplasty (<jats:styled-content style=\"fixed-case\">CDCP<\/jats:styled-content>) may be discussed if preoperative examination indicates canalicular stenosis and dacryocystorhinostomy is not desirable. However, the patient needs to be aware of the higher risk for additional surgery, especially if a second stenosis is found during
