Comparison of endoscopic revision for failed primary external versus endoscopic dacryocystorhinostomy

Abstract

The success rate of revisional dacryocystorhinostomy in the previous external dacryocystorhinostomy group was slightly higher than that in the previous endoscopic dacryocystorhinostomy group. Differences in preoperative and perioperative endoscopic findings were detected between the groups. Clarifying these differences in endoscopic revision will help improve the surgical outcomes of primary surgery involving either external or endoscopic dacryocystorhinostomy.

Success Rates in Powered Endonasal Revision Surgery for Failed Dacryocystorhinostomy in a Tertiary Referral Center

“…12 Interestingly, significantly more inappropriately sized or posi tioned ostium were found following previous endonasal DCR. Our study did not find this association with ostium size or position.…”

“…Previously reported success rates in adults for REEDCR range from 60% to 94% (Table 2). [8][9][10][11][12][13][14][15][16][17][18] The out come measures used vary widely, and not all studies reported both anatomical and functional success.…”

“…Stents are indicated in revision surgery, unlike the trend in primary endo scopic DCR where it is increasingly normal to omit intubation, due to the high rate of common canalicular fibrosis and multiple causes of failure. 12,20 The serrated oscillating blade allows rapid and precise fashioning of nasal and lacrimal sac mucosa with enhanced visualization of the surgical site by the attached aspirator, which removes irrigating saline and debris. Its minimally invasive approach reduces complications by avoiding adjacent tissue damage and improves surgical outcomes.…”

About endonasal laser dacryocystorhinostomy unfavorable outcomes

“…Так, например, имеются данные, согласно которым процент недостаточно эффек-тивных оперативных вмешательств составляет 5-16 % при наружном доступе и до 40 % при эндоскопическом [10,11]. Существуют также данные ретроспективного исследования 77 па-циентов, подвергшихся ревизионной ДЦРС, в результате которого также выяснилось, что успешность эндоскопической дакриоцисторино-стомии несколько меньше (80,7 %), чем наружной (84 %) [13].…”
