Aerocyst urethral catheter insertion compared to expansion sponges application in external dacryocystorhinostomy.
ABSTRACT To evaluate the clinical effect and complications of two different filling materials (aerocyst urethral catheter and expansion sponges) applying in external dacryocystorhinostomy (EXT-DCR) and compare their advantages and disadvantages.
A retrospective study was made in the period from April, 1 2000 to April, 1 2005. Totally 180 patients (240 eyes) underwent the EX-DCR using different filling materials and divided into three groups randomly: negative control groups (group 1), expansion sponges group (group 2) and aerocyst urethral catheter group (group 3). The gender, etiology, clinical findings, surgical technique, filling materials, the condition of ocular surface and complications were analyzed. Filling materials were removed during day 7. Postoperative success was determined by lacrimal patency to irrigation, a positive dye test, hemorrhage and errhysis conditions after extubation and subjective resolution of epiphora and liquor puris.
During a mean follow-up of 5.14±1.69 years, the success rate were 73.7% (group 1), 86.5% (group 2), 98.7% (group 3) in three groups. There was significant statistical difference among three groups in the surgical success rate and the operative complications (including hemorrhage, errhysis, periorbital ecchymosis after extubation)(P<0.05).
EXT-DCR with aerocyst urethral cathete intraoperatively have higher success rate, fewer operative complications and a high patient satisfaction ,and can be used to simplify and speed up traditional EXT-DCR.
Article: Four-year experience with intranasal transilluminating dacryocystorhinostomy using ultrasound.[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to investigate the results obtained by intranasal dacryocystorhinostomy. This was a prospective, non-randomised, non-comparative case series study of 150 patients with epiphora due to nasolacrimal duct obstruction. The same team of ophthalmic and otorhinologic surgeons performed the transilluminating intranasal dacryocystorhinostomy using ultrasound. The main outcome measures were subjective improvement of epiphora, dye testing, lacrimal probing, lacrimal irrigation, and endoscopic nasal examination. Symptomatic relief and patency of the lacrimal apparatus was achieved in 92% (138) of the patients at the 3-month follow-up and 89% (134) at the 6-month follow-up. At 1 year, only 2 patients of the 134 initial successes showed obstruction of the nasolacrimal duct. All 16 successful patients that we have followed for 4 years have sustained their improvement. Transilluminating intranasal dacryocystorhinostomy is a quick and safe option for the treatment of nasolacrimal duct obstruction. The main advantages over external dacryocystorhinostomy are avoidance of skin incision, reduced haemorrhage, shorter duration of the operation, and quicker recovery of the patient.Canadian Journal of Ophthalmology 11/2005; 40(5):627-33. · 1.47 Impact Factor

ABSTRACT: The aim of this article is to present a different endoscopic dacryocystorhinostomy technique and its results on patients with blockage of the nasolacrimal drainage system. Eleven patients (seven female and four male) who had chronic epiphora with the diagnosis of chronic nasolacrimal duct blockage were operated on using T-type ventilation tubes. Oral antibiotics, nasal steroids, oral antihistamines, and antibiotic eyedrops were given to all cases. The ventilation tubes were removed 3 months after surgery. Of 11 cases, 9 patients had unilateral and 2 patients had bilateral blockage. Eleven sides of nine patients were symptom free (85% success rate), and two patients had decreased continuation in complaints. Granulation tissue occurred in two revision patients. Endoscopic dacryocystorhinostomy using a T-type ventilation tube is an easy and cost-effective alternative and has low complication rates in the management of patients with nasolacrimal duct obstruction.The Journal of otolaryngology 07/2007; 36(3):164-7. · 0.50 Impact Factor
