Effect of timing of external dacryocystorhinostomy on surgical outcome.

PURPOSE: To present our experience with external dacryocystorhinostomy (DCR) outcome and to compare cases of early and late DCR. METHODS: Retrospective data review of all patients who had external DCR with silicone intubation in a 7-year period. Data were collected and analyzed concerning patients' preoperative and postoperative symptoms, and the lacrimal drainage system examination before, during, and after surgery. RESULTS: In all, 162 patients underwent 195 DCR surgeries for nasolacrimal duct obstruction. Success was achieved in 81% of surgeries. Success rates were higher in patients who had early DCR (tearing only or early inflammatory signs of the lacrimal sac, 84% success) than in cases that had late DCR (more than 6 months after inflammation started, 77% success). These differences were statistically insignificant. Failure of DCR was much higher in posttraumatic DCR than in DCR for other etiologies. Complications (in 9% of surgeries) were generally mild and infrequent, except 1 case of meningitis. CONCLUSIONS: In experienced hands, external DCR has good postoperative success with a low complication rate. Early DCR does not have a substantial advantage over late surgery with regard to surgical outcome.

Posterior lamellar gold-weight extrusion.

We report a case of a man who had undergone gold eyelid loading for lagophthalmos 22 years earlier. During examination for a complaint of foreign body sensation in the operated eye, the gold weight was found under the palpebral conjunctiva. Although extrusion of a gold weight through the skin anteriorly is well recognized, posterior extrusion has not been previously reported. Although such an extrusion involves tarsal plate erosion, the patient's complaints in this case were minor, probably due to the chronic nature of the process. This finding should serve to draw the attention of surgeons using gold eyelid loading to the possible, albeit rare, complication of posterior extrusion.
