Conclusion
Powered endoscopic DCR allows the lacrimal sac to be fully exposed so that it stands proud of the lateral nasal wall after dissection. By fully preserving all the lacrimal mucosa during opening of the sac, the sac can be marsupialized into the lateral nasal wall, becoming part of the lateral nasal wall. This marsupialization is different from creating an ostium into the sac. Complete marsupialization decreases the l ikelihood of closure of the sac. In addition, preservation of the nasal mucosa allows this mucosal flap to be trimmed so that the nasal and lacrimal mucosa can be opposed to ensure primary intention healing rather than secondary intention healing and potentially lessens the risk of fibrosis and subsequent closure of the lacrimal ostium. Results of this procedure have proved to be reliable in primary, revision, and in pediatric DCRs.
