Revison endonasal dacryocystorhinostomies: analysis of 44 procedures

Abstract

Purpose: To determine the success rate of revision endoscopic dacryocystorhinostomies (DCR) and to analyse 44 revision DCRs. Methods: The operative and postoperative data were collected in 44 revision DCRs. The corrections of associated structural anatomic alterations were performed during the surgery (resection of the scarr, the bone window creating, resection of the head of the middle turbinate, septoplasty, ethmoidectomy etc.) and the intubation was performed in all cases. Results: The follow-up interval ranged from 12 to 36 months. The 44 ReEDCRs were performed in adults and there were only 5 children under the age of 15. The surgery was performed under local or general anaesthesia. The most frequent secondary procedures were scar resections, creating a wider bone window, and partial middle turbinate resection. Four patients were excluded for their follow-up periods had not been completed. An average time of the tubes removal was 5.6 months. The total success rate was 84.0%; the success rate was 85.7% in the group with closed rhinostomy and 1/2 in the group of canalicular and rhinostomy obstructions. Conclusions: The endonasal revision DCR is a safe and very effective surgical procedure following the failed DCRs. The correction of associated structural anatomic alterations that may be involved in the failure of previous surgeries can be easily performed.

Mitomycin C–Enhanced Revision Endoscopic Dacryocystorhinostomy

“…We had about an 81% success rate in the nonmitomycin group 15 months after surgery. Kominek et al 14 reported an 84% success rate in nonmitomycin revision endoscopic DCR in their cohort of 44 patients. Korkut et al 15 reported an 84% success rate in revision endoscopic DCR without mitomycin as well.…”

The importance of scintigraphic qualitative and quantitative measurements in patients with epiphora due to unilateral punctum stenosis

“…In recent years, minimally invasive procedures such as endoscopic DCR and transcanalicular diode lasers have been preferred (26)(27)(28)(29)(30)(31). DSG is also useful in assessing the success of these techniques (32)(33)(34)(35)(36)(37).…”
