Principles of Surgical Technique in DCR

Many different ways of creating a rhinostomy have been described, but the main objectives are:

1 To create a rhinostomy from the sac through the lateral nasal wall.

2 To create a rhinostomy that is about 5 mm wide (Figure 14.16a, b).

3 To minimize trauma to the lacrimal system and sac.

4 To minimize damage to the mucosa around the rhi-nostomy site.

5 To avoid a high rhinostomy, as this can produce a sump syndrome.

6 To avoid collateral mucosal damage in the nose, to minimize the formation of adhesions.
