Nonendoscopic endonasal dacryocystorhinostomy: Outcome in 134 eyes

Aims:To evaluate the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN-DCR) in patients with nasolacrimal duct obstruction (NLDO) in India.Methods:Retrospective case series of NEN-DCR between July 2012 and October 2014. All patients had follow-up >3 months. Success was defined anatomically as patency on irrigation and functionally as relief from epiphora.Results:A total of 122 patients (134 eyes; 81 female; mean age 37 ± 18 years) were included. Indications were primary acquired NLDO in 92 (68%) eyes of adults (>18 years), NLDO in children (<18 years) in 22 eyes (16%), acute dacryocystitis in 13 eyes, failed prior DCR in six eyes, and secondary acquired NLDO in one eye. Mean duration of surgery was 36 min (range: 16–92). At a median follow-up of 6 months (range: 3–15), 86% eyes had functional success and 85% had anatomical success. Revision NEN-DCR was successful in 13/16 eyes. All patients with acute dacryocystitis were completely symptom-free at final visit. In children, (17/22) 77% achieved functional success after primary NEN-DCR which improved to 100% after one revision. Tube-related epiphora and granuloma in ten eyes resolved after removal.Conclusion:NEN-DCR gives good outcome in primary NLDO and is also effective in those with acute dacryocystitis and in children with NLDO. The technique obviates the need for an endoscope and has an acceptable safety profile and thus may be particularly suited for the developing nations.     

Paediatric endoscopic endonasal dacryocystorhinostomy in congenital nasolacrimal duct obstruction

Objectives The objectives of this study were to report a series of paediatric patients who underwent endoscopic endonasal dacryocystorhinostomy (DCR) for primary congenital nasolacrimal duct obstruction (NLDO).Methods This is a retrospective, noncomparative review of all consecutive cases in two lacrimal clinics between January 1999 and October 2004. The main outcome measures were patients’ demographics, previous treatments, clinical presentation, operative and postoperative complications, postoperative follow-up and resolution of epiphora.Results Twenty-one patients (15 males) with a mean age of 6±3.5 years (range, 2–14 years) underwent 26 endoscopic DCR operations for congenital NLDO. Sixteen cases were unilateral, and five were bilateral. In 13 cases (50.0%), there was a history of epiphora and chronic dacryocystitis with or without a mucocele. Two cases (7.7%) presented with acute dacryocystitis, and 11 (42.3%) had only a history of epiphora. Previous procedures included probing and irrigation in 25 cases (96.2%) and insertion of Crawford tubes in 19 cases 973.1%). During a mean postoperative follow-up period of 18±8 months, the anatomical success rate (free flow of fluorescein sodium and patency of ostium on nasal endoscopy) was 100%, and the clinical success rate (resolution of epiphora) was 92.3%.Conclusion Endoscopic endonasal DCR is an effective treatment modality for congenital NLDO that compares favourably with the reported success rates of external DCR.     

Effects of Merogel coverage on wound healing and ostial patency in endonasal endoscopic dacryocystorhinostomy for primary chronic dacryocystitis

Purpose

To investigate the effects of Merogel coverage on ostial patency in endonasal endoscopic dacryocystorhinostomy (EES-DCR) for primary chronic dacryocystitis (PCD).

Methods

In all, 260 patients with unilateral PCD were randomized into two groups: the Merogel group and the control group. All patients underwent EES-DCR. The Merogel group received Merogel covering the wound 1–2 mm around the ostium and the control group received no treatment. Patients were followed up for 9 months. The mucosal epithelialization of the wound, the proliferation of fibrosis tissue, and the success rate of ostial patency were compared.

Results

Our study included 112 patients in the Merogel group and 115 patients in the control group. At the 2-week review, intact mucosal epithelium lined the ostia in 96 Merogel patients compared with 80 control patients (ITT analysis: χ ²=4.502, P=0.034). At the 9-month review, scars were present in 18 patients in the Merogel group compared with 39 patients in the control group (ITT analysis: χ ²=9.909, P=0.002, ITT analysis). No differences were observed in the granulation formation between the two groups. The success rate of ostial patency reached 94.6% (106/112) in the Merogel group compared with 80% (92/115) in the control group (ITT analysis: χ ²=4.151, P=0.042).

Conclusion

Merogel coverage may enhance the success rate of EES-DCR for PCD by promoting mucosal epithelial healing and preventing excessive scarring.

Pediatric endonasal dacryocystorhinostomy: A multicenter series of 116 cases

We report our experience with pediatric endonasal dacryocystorhinostomy (DCR). Multicenter, retrospective, noncomparative study. Cases of pediatric endonasal DCR during 2006–2011 were included from six oculoplastic units. Patients over the age of 16 years were excluded. The outcomes of pediatric endonasal DCR are presented. Indication for surgery, demographics, previous interventions, intraoperative or postoperative complications, follow-up duration, and success rate (defined as significant improvement of epiphora) were evaluated. In total, 116 endonasal DCRs were performed for 103 patients. The mean follow-up period was 8 months (range 3 months to 4 years), with 1 patient lost to follow-up. There were 48 males (mean age 5 years and 9 months) and 50 females (range of 4 months to 16 years), with a total of 98 cases of congenital nasolacrimal duct obstruction (CNLDO) (84.5%) and 18 cases of acquired nasolacrimal duct obstruction (ANLDO) (15.5%). Previous interventions included probing 75.9% (88/116), massaging 43.1% (50/116), and intubation 39.7% (46/116). There were no intraoperative complications. There was one case of postoperative pyogenic granuloma. There were no cases of postoperative infection and postoperative hemorrhage. Ninety percent of procedures were considered successful. Complete symptom resolution was observed in 78% (90/116), significant improvement in 12% (14/116), partial improvement in 2% (2/116), and no improvement in 8% (9/116). In our series, we demonstrated that endonasal DCR is a safe operation and has an overall success rate of 90% for pediatric NLDO.
