Limited Approach in Endoscopic Dacryocystorhinostomy of Pediatrics

Abstract

Background: Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR) a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences. Materials and Methods: An experimental study was done in pediatric DCR with limited approach (age < 14-year-old). After written consent, with general anesthesia, with nasal endoscopic surgery, lacrimal bone is exposed and extruded. In contrast with routine procedure, ascending process of maxillary sinus reserve; and marsupialization and wide exposure to lacrimal sac was done only by lacrimal bone defect; and cannulation preserve with temporary silicone tube. Results: Between 2006 and 2012, 16 pediatric DCR was done by a unique surgeon in 2 otorhinolaryngologic centers. Before surgery 14 (87.5) had epiphora, 3 (18.8) had eye discharge, and 3 (18.8) had eye sticky eye. Two (12.5) had history of facial trauma, and 10 (62.5) had congenital nasolacrimal duct insufficiency. Five (31.3) had history of dacryocystitis. Patients were followed for 17 +/- 9 months. Silicone tube stayed for 4 +/- 2.5 months. We could follow 7 patients and minimal improvement or need to revision surgery considered as technical failure. After surgery, 3 patients had no epiphora with complete improvement; 2 had very good improvement with confidence of the patients and parents; 2 cases had unsuccessful surgery in our patients, who needs to another surgery. One of them had several probing and surgery before our endoscopic DCR. Conclusions: Limited approach in endoscopic DCR of pediatrics can be done in noncomplicated patients, with minimal manipulation, more confidence, and acceptable results.
