Purpose:
Dacryocystorhinostomy (DCR) is the standard surgical treatment for adult nasolacrimal duct obstruction. There have been relatively few studies of closed nasolacrimal duct intubation in adults. The aim of this study was to determine rates of anatomic patency following this procedure.
Methods:
The authors carried out a survey of all patients undergoing closed nasolacrimal duct intubation as a primary procedure over a period of 3 years and 4 months. There were 32 eligible patients of whom 20 attended for review.
Results:
A total of 75% of these cases had patent drainage after follow-up of between 6 months and 3 years. The proportion of patients with persistent patency after intubation was the same regardless of length of follow-up.
Conclusions:
The minimally invasive procedure of lacrimal intubation may have a role in some adults with nasolacrimal duct obstruction.

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
