Abstract

PURPOSE: The aim of this study was to describe the surgical method of endoscopic conjunctivodacryocystorhinostomy with Jones tube insertion using a Castroviejo double-ended lacrimal dilator and to elucidate the surgical outcomes. METHODS: Under general anesthesia and preoperative epinephrine soaking, a monopolar needle cautery instrument was used to remove the nasal mucosa over the lacrimal and maxillary bone junction. After the lacrimal and maxillary bone junction was exposed, an oval osteotomy was formed. A Castroviejo double-ended lacrimal dilator was then inserted to create a direct fistula from the conjunctiva to the nasal cavity through the bony ostium. The dilator was grasped and withdrawn using smooth forceps to determine the tube length. The selected tube was then inserted into the fistula with a guide probe. Following removal of the probe, the inserted tube was fixed with 7-0 Ethilon suturing. RESULTS: Among 39 patients, a total of 49 cases were examined. The success rate was 73.4% (36/49 eyes). The average surgical time was 29.1 minutes for single-eye operations and 47.3 minutes for double-eye operations. Lateral migration (6/13; 46.2%), medial migration (3/13; 23.1%), granulation tissue obstruction (2/13; 15.4%), inflammation (1/13; 7.7%), and malpositioning (1/13; 7.7%) were the noted complications that led to reoperation. CONCLUSIONS: In conclusion, surgical management of endoscopic conjunctivodacryocystorhinostomy using a Castroviejo double-ended lacrimal dilator has several advantages. Using this device, easier surgical procedure, shorter surgical time, and more favorable success rate can be achieved without serious complications.
