What are the steps of dacryocystectomy

summary

A while ago, I had acute dacryocystitis. After going to the hospital for examination, the results showed that I still had a lacrimal sac fistula in my body, so the doctor suggested that I should have a dacryocystectomy. Now let's talk about the steps of dacryocystectomy.

What are the steps of dacryocystectomy

First: skin incision. 3 mm from the nasal side of the inner canthus, from 2 ~ 3 mm above the inner canthus ligament, cut the skin downward along the dermatoglyph. The upper part of the incision is vertical, and the lower part is curved to the temporal side, with a total length of 12 ~ 15 mm. The direction of the skin incision is roughly parallel to the anterior lacrimal ridge.

Second, separate the subcutaneous tissue and muscle layer. The incision skin and subcutaneous tissue were separated, and the orbicularis oculi muscle and superficial lacrimal fascia were separated in turn. Find out the position of anterior lacrimal ridge. Whether the medial canthus ligament should be cut or not depends on the surgeon's personal experience.

Third, separate the lacrimal sac. The superficial lacrimal fascia covering the surface of lacrimal sac was cut along the anterior lacrimal ridge under the inner canthal ligament to the upper end of nasolacrimal duct (there was honeycomb tissue between the superficial lacrimal fascia and lacrimal sac). With a periosteal separator, the lacrimal fascia was separated from the lacrimal sac by gently moving from the upper end of the nasolacrimal duct to the lower edge of the medial canthal ligament between the lacrimal fascia and the lateral wall of the lacrimal sac.

matters needing attention

According to the above content, we have a certain degree of understanding about the treatment of dacryocystectomy. In addition to these, patients need to know whether they meet the requirements of surgery before receiving treatment. In addition, postoperative care is also very important.
