Randomized Controlled Trial on Silicone Intubation in Endoscopic Mechanical Dacryocystorhinostomy (SEND): An 11-year Outcome Report. Semin Ophthalmol 2024:1-7. [PMID: 39246013 DOI: 10.1080/08820538.2024.2385391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 07/15/2024] [Accepted: 07/18/2024] [Indexed: 09/10/2024]
Abstract
PURPOSE To compare the long-term outcomes of mucosal-sparing mechanical endoscopic dacryocystorhinostomy (MMED) for primary acquired nasolacrimal duct obstruction (PANDO) with or without silicone intubation. METHODS An 11-year follow-up study of the Silicone intubation in Endoscopic Dacryocystorhinostomy (SEND) randomized controlled trial (RCT) was conducted at a university-affiliated dacryology clinic from December 2019 to March 2023. Questionnaires on symptoms, anterior segment examination, endoscopic examination with functional endoscopic dye test (FEDT) and FICI grading, and ostial size measurements using Image J software were performed by a masked ophthalmologist. The primary outcome was surgical success, defined by Munk's score ≤1 and a positive fluorescein endoscopic dye test. Secondary outcomes included risk factors for failure and outcomes of revision surgeries. RESULTS Fifty-three of the original 118 patients were evaluated at 155 ± 21 (136-218) months postoperatively. Seventy-seven percent (46/60) ostia remained successful, including 70% (19/27) of unstented and 82% (27/33) of stented ostia (p = .3). Stented ostia had larger size (p = .003), but this did not confer higher success (p = .14). Successful ostia had higher FICI scores and better ostial dynamicity (p < .05). Ostium movement was the only parameter associated with surgical success on multivariate analysis (OR 13.1, p = .01). Four (1 stented) underwent revision MMED, intraoperative mitomycin-C, and 12-week intubation. All revision ostia were functional after 141 ± 43 months. CONCLUSIONS Surgical success of MMED after 11-years was 77%, a notable reduction compared to 96% success at 1-year. Statistical advantage of silicone intubation for primary MMED was not demonstrated, though clinically, stented ostia had a higher success (82% vs 70%). The presence of a dynamic internal common opening was highly associated with long-term surgical success.

[PMID: 39048646 PMCID: PMC11269684 DOI: 10.1038/s41598-024-67620-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2024] [Accepted: 07/14/2024] [Indexed: 07/27/2024] Open
Abstract
This study aimed to elucidate the regression process of ostium granulomas under the usage of intranasal steroid after primary endoscopic dacryocystorhinostomy (DCR). The authors retrospectively reviewed 57 patients (a total of 72 ostia) who had ostium granulomas after primary endoscopic DCR between 2011 and 2015. Topical intranasal steroid spray was applied in all the patients since postoperative day 1. Adjunctive intralesional triamcinolone acetonide injections were administered for extensive and large-sized granulomas that caused impending ostium blockage. Sequential regression of the ostium granulomas and success rates of DCR were assessed using endoscopic photos. The granulomas completely disappeared in 69 (95.8%) ostia, and the average time interval from the surgery to the disappearance was 6.9 ± 2.8 months. Anatomical and functional surgical success rates were 90.3% and 84.7%, respectively. Intralesional steroid injections for ostium granulomas did not alter the outcomes compared to topical intranasal steroid usage significantly (p = 0.445). In conclusion, we observed that, by continuing the usage of intranasal steroids, ostium granulomas disappear gradually at postoperative 6 months. The intranasal surgical manipulation of granulomas, which results in more mucosal cicatricial change and impedes patient satisfaction, can be successfully avoided.

Ali MJ. Alterations of Lacrimal Sac Microbiota in Failed Dacryocystorhinostomy: The Lacriome Paper 6. Semin Ophthalmol 2024; 39:324-329. [PMID: 38461372 DOI: 10.1080/08820538.2024.2327481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 03/02/2024] [Indexed: 03/11/2024]
Abstract
PURPOSE To study the metagenomics of the microbes isolated from the lacrimal sac in patients with failed dacryocystorhinostomy (DCR). METHODS A prospective study was performed on 10 consecutive patients with failed DCR. Lacrimal sac samples were obtained for metagenomic analysis during the revision endoscopic DCR. The samples were collected intraoperatively after a full-length lacrimal sac marsupialization and immediately transported on ice to the laboratory. A whole shotgun metagenome sequencing was performed on the IlluminaTM platform following DNA extraction and library preparation. The downstream analysis of the samples was performed using various software packaged in the Squeeze Metapipeline v1.3.0 and marker gene-based metagenomic phylogenetic analysis using MetaPhlAn4. RESULTS The five major phyla identified across the samples of failed DCR include Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes, and Fusobacteria (Figure 1). The prevalent species include Stenotrophomonas maltophilia, Pseudomonas juntendi, Streptococcus pneumoniae, Acinetobacter ursingii, Citrobacter koseri, and Cutibacterium acnes (Figure 2). Among the other organisms identified, few were from genera candida and mezorhizobium. Among the viruses, the most abundant was the BeAn 58058 virus. It was interesting to note the occasional presence of plasmodium and toxoplasma species. The functional category distribution of KEGG (Kyoto encyclopedia of genes and genomes) data showed microbial metabolism to be the most involved function, followed by cellular processes. CONCLUSION This is the first whole metagenome sequencing of the lacrimal sac contents from failed DCR patients. The organisms identified varied significantly from those isolated from patients with primary acquired nasolacrimal duct obstruction (PANDO) using similar techniques and reflect altered lacrimal microbiota in surgically unsuccessful DCRs.

Int Ophthalmol 2024; 44:14. [PMID: 38321290 DOI: 10.1007/s10792-024-02972-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 12/04/2023] [Indexed: 02/08/2024]
Abstract
PURPOSE To evaluate the association of tear meniscus height (TMH) with clinical outcomes of patients who underwent endonasal dacryocystorhinostomy. METHODS We recruited 304 patients from two institutes. The TMH was measured using anterior segment optical coherence tomography before surgery. All patients underwent endoscopic DCR with lacrimal intubation stent insertion. The lacrimal stent was removed 2 months after surgery. The TMH was measured at 2 months and 12 months after surgery. Improvements in epiphora were assessed using a visual analogue scale (range, 0-2). Recurrence was determined based on lacrimal irrigation and endoscopic evaluation results. RESULTS All patients experienced improvements in subjective symptoms 2 months after surgery. The mean TMH also decreased significantly compared with that before surgery. During the follow-up period, four patients experienced recurrence. The mean TMH 12 months after surgery was significantly lower than that before surgery. The rate of change in the TMH was significantly associated with the use of a dacryoendoscope during sheath-guided lacrimal stent intubation at all time points. Of the 251 patients who were followed up at 12 months after surgery, three reported recurrences, and 17 reported mild improvement of epiphora. The rate of change in the TMH was significantly associated with epiphora improvement. Height was also associated with epiphora improvement. CONCLUSIONS Endoscopic DCR is an acceptable surgical procedure for managing nasolacrimal duct obstruction. Sheath-guided lacrimal stent intubation using a dacryoendoscope resulted in a greater reduction in postoperative TMH compared to the blind insertion technique, which may lead to favorable clinical outcomes.

Abstract
PURPOSE This study aimed to report the practice patterns while performing revision dacryocystorhinostomy (RevDCR) amongst oculoplastic surgeons from several regions across the globe. METHODS The survey consisted of 41 specific questions sent via email that contained a link to the Google forms. The questions covered several aspects of the respondents' practice profiles, evaluation methods, pre-operative choices, surgical techniques, and follow-up preferences while dealing with patients of prior failed DCRs. Questions were answerable either as multiple choice or free text typing. The survey respondents were anonymized. The responses were collected and analyzed, and data were tabulated to understand the preferred practice trends. RESULTS A total of 137 surgeons completed the survey. Most respondents identified themselves as experienced surgeons managing failed DCRs (76.6%, total respondents (n) = 137). The commonly preferred modalities for evaluation of a failed DCR were lacrimal irrigation (91.2%) and nasal endoscopy (66.9%). About 64% (87/137) of the respondents performed a combination of nasal endoscopy, lacrimal irrigation, and probing to localize the area of the failed DCR. A majority of the respondents used anti-metabolites (73.3%, n = 131) and stents (96.4%, 132/137) during the revision surgery. Most surgeons preferred endoscopic approach (44.5%), (61/137) for revising a failed DCR and most preferred general anaesthesia with local infiltration (70.1%, 96/137). Aggressive fibrosis with cicatricial closure was identified as the most frequently encountered cause of failure (84.6%, 115/137). The osteotomy was performed on an as-needed basis by 59.1% (81/137) of the surgeons. Only 10.9% of the respondents used navigation guidance while performing a revision DCR, mainly for post-trauma scenarios. Most of the surgeons completed the revision procedure within 30-60 minutes (77.4%, 106/137). The self-reported outcomes of revision DCRs were good (80-95%, median-90%, n = 137). CONCLUSION A significantly high percentage of oculoplastic surgeons who responded to this survey from across the globe performed nasal endoscopy in their pre-operative evaluations, preferred endoscopic surgical approach, and used antimetabolites and stents while performing revision DCRs.

Reference role of middle turbinate axilla in lacrimal sac localization assisted by computed tomographic dacryocystography-reference value of middle turbinate in locating lacrimal sac. BMC Ophthalmol 2022; 22:500. [PMID: 36539768 PMCID: PMC9764462 DOI: 10.1186/s12886-022-02740-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND The middle turbinate axilla (MTA) has always been used as a stable anatomic landmark for endoscopic surgeons to locate the lacrimal sac on the lateral nasal wall. Yet, little is known about whether the lacrimal sac size will affect the positioning effect of MTA on lacrimal sac. The aim of this study was to investigate the regularity of lacrimal sac size and lacrimal sac localization through the reference position of the MTA on computed tomographic dacryocystography (CT-DCG) images. METHODS A series of 192 endoscopic dacryocystorhinostomy (DCR) surgeries were performed. All the patients had been diagnosed as unilateral nasolacrimal duct obstruction and received CT-DCG examinations. According to the maximum transverse diameter of the lacrimal sac on CT-DCG, the patients were classified into three groups. Measurements were taken on CT-DCG parasagittal images. RESULTS The average distance from the sac superior fundus (SSF) to the MTA was 7.52 mm ± 3.23 mm, and it increased with the increase of the maximum transverse diameter of the sac among groups (p < 0.01). The average distance from the common canaliculus (CC) to the MTA was 3.95 mm ± 2.49 mm. No significant difference was observed among the groups (p = 0.11). The average distance from the CC to the SSF was 3.41 mm ± 1.31 mm, and it increased with the increase of the sac transverse diameter among groups (p < 0.01). CONCLUSIONS The lacrimal sac can be accurately located on the lateral nasal wall by the reference position of the MTA on CT-DCG images. The distance of the SSF to the MTA and the SSF to the CC is related to the lacrimal sac size. The relative position of the CC to the MTA is relatively stable on CT-DCG images, which make it possible to locate the lacrimal sac of different sizes and the corresponding nasal mucosa incision design in endoscopic DCR.

Abstract
AIMS The authors sought to assess the changes in eyelid position after silicone tube insertion and removal in endoscopic dacryocystorhinostomy. METHODS The authors retrospectively reviewed 60 eyes of 48 consecutive patients who underwent endoscopic dacryocystorhinostomy operation at Korea University Guro Hospital, Seoul, Republic of Korea, between April 2019 and November 2019. All cases were evaluated to discern eyelid positioning, focusing on the marginal reflex distance 1, medial palpebral fissure, central palpebral fissure (PF-2), lateral palpebral fissure (PF-3), and medial canthal angle (MCA) before surgery and at 1 week and 1, 2, 3, and 4 months postoperatively. RESULTS Twelve patients (25%) were operated on bilaterally and 36 patients (75%) were operated on unilaterally. The average patient age was 56.5 years and 9 men (18.8%) and 39 women (81.3%) were included in this study. At 2 months postoperatively, all values of interest (marginal reflex distance 1 , medial palpebral fissure, PF-2, PF-3, and MCA) had decreased significantly (P < 0.05, Friedman test), but the changes in PF-3 immediately after surgery were not significant (P = 0.062, Wilcoxon rank-sum test). From 2 to 3 months after surgery, all 5 indicators of interest increased significantly. After silicone tube removal, whereas there was no statistically significant difference in medial palpebral fissure, PF-3, and marginal reflex distance 1 values; the changes in PF-2 and MCA values as compared with before surgery was 0.47 mm (P = 0.02, Wilcoxon test) and 3.25° (P = 0.000, Wilcoxon test), respectively, which was significantly different. However, with these small gaps, it will be difficult to notice the changes in PF-2 and MCA values during clinical examination. CONCLUSION Insertion of a silicone tube during endoscopic dacryocystorhinostomy leads to temporary deformation of the lid position. However, after silicone tube removal, all eyelids recovered to their original shape.

Abstract
Purpose Endoscopic endonasal balloon-assisted dacryoplasty is a minimally invasive surgical approach that can be applied after failure of dacryocystorhinostomy with recurrence of distal acquired lacrimal obstruction. Methods At the Department of Otolaryngology, San Raffaele Hospital, Milan (Italy), from December 2016 to October 2020, 14 patients underwent trans-nasal balloon-assisted dacryoplasty after a failed dacryocystorhinostomy (both external and endoscopic endonasal). The routinary pre-operative work-up included multidisciplinary study of the lacrimal disease, which consisted in primary ophthalmological and otorhinolaryngological visits associated with nasal endoscopy, in which a radiological exam was added if needed. The surgical approach includes pneumatic enlargement of the stenotic rhinostomy, created during the primary dacryocystorhinostomy, using a high-pressure trans-nasal balloon catheter. Anatomical success was considered when the ostium was patent upon irrigation, while functional success was considered as resolution of epiphora or free lacrimal flow on functional test. Results Among 14 patients included and after a mean follow-up of 19.5 months (range 13–51 months), anatomic success was achieved in 100% of patients and functional success was achieved in the 85.7% (12/14). Operative time ranged from 9 to 28 min (mean 18 min) and no complications were reported. Conclusion Trans-nasal balloon-assisted dacryoplasty is a mini-invasive surgical approach to treat failed dacryocystorhinostomies with reliable and stable outcomes in the long term. The absence of post-surgical complications, high success rate and short operative time are the main features of this innovative procedure.

Abstract
Our purpose was assess the long-term efficacy of 4-mm coronary balloon catheter dacryoplasty in revision endoscopic dacryocystorhinostomy (RevEnDCR). This retrospective interventional case-series was performed for patients who underwent RevEnDCR aided by a 4-mm coronary balloon catheter (CBC) dacryoplasty. The indications for the surgery were previously failed DCRs by external or endoscopic approach where the ostium showed near total cicatrization with or without the presence of organized granuloma threatening the internal common opening (ICO). The coronary balloon (4 × 10 mm, SPALNO, Cardiomac, Haryana, India) with the guidewire was used and a minimum of >12 months of follow-up was considered for analysis. Ten lacrimal systems of eight patients with mean age of 48.8 years underwent CBC-assisted revision endoscopic DCR. Of the 10 failed DCRs, 6 had a previous external approach DCR and 4 were endoscopic DCRs. Grossly stenosed ostium with near total cicatricial closure were noted in half of the patients (50%, 5/10) while the remaining half, in addition, showed organized granulomas threatening the ICO. The surgical technique using CBC was found to be minimally invasive, easy to perform with multiple advantages like uniform clearance of the area in front of ICO and more predictable lacrimal sac flaps. At a mean follow-up of 20 months, anatomical and functional success were achieved in 90% (9/10) of the eyes. We conclude that coronary balloon catheter-assisted revision endoscopic DCR is a minimally invasive and viable alternative in select group of patients of failed DCR with near total cicatrisation or organized granulomas threatening ICO.

Abstract
BACKGROUND Endoscopic dacryocystorhinostomy (EN-DCR) is an increasingly common procedure performed by otolaryngologists. While EN-DCR has a high rate of success at relieving blockage of the lacrimal system, little is known regarding associated postoperative infection (POI) rates and risk factors. OBJECTIVE The purpose of this study was to identify factors associated with the occurrence of postoperative orbital and rhinologic infection in a large cohort of patients undergoing EN-DCR. METHODS A retrospective review of 582 patients who underwent EN-DCR was performed. All patients received antibiotic prophylaxis as a single intraoperative intravenous administration and a ten-day postoperative oral course. Clinical and demographic information was reviewed, including the occurrence of acute orbital or rhinologic infection within 30 days of surgery. Multivariable analysis was performed to identify risk factors associated with POI. RESULTS Fifteen of 582 patients (2.6%) developed POI following EN-DCR. The most common POI was acute rhinosinusitis (10/15, 66.7%), followed by acute dacryocystitis (2/15, 13.3%), preseptal cellulitis (2/15,13.3%), and acute bacterial conjunctivitis (1/15, 6.7%). The majority of patients (464/582, 79.7%) underwent concurrent endoscopic sinus surgery (ESS). In most cases (302/464, 65.1%), ESS was performed to address comorbid rhinosinusitis, whereas 7.8% (36/464) of patients underwent surgery to enhance surgical access to the lacrimal sac. Patients who underwent concurrent ESS were less likely to develop POI (OR: 0.17, CI: 0.04-0.80, p < 0.05). Evidence of mucopurulence at surgery increased the likelihood of POI (OR: 6.24, CI: 1.51-25.84, p < 0.05). CONCLUSION Mucopurulence at the time of surgery significantly increased the risk of POI, whereas concurrent ESS, performed most commonly to address comorbid rhinosinusitis, significantly decreased the risk of POI. Awareness of risk factors for POI and appropriate surgical management of concurrent rhinosinusitis can lead to reduced infectious complications after EN-DCR.

[PMID: 32521057 DOI: 10.1002/lary.28795] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/10/2020] [Accepted: 05/14/2020] [Indexed: 11/08/2022]
Abstract
OBJECTIVES/HYPOTHESIS Revision endoscopic dacryocystorhinostomy (END-DCR) is the preferred approach for failed primary surgeries, yet quality data on long-term outcomes are lacking. This study aimed to evaluate three aspects of revision END-DCR: 5-year success rates, patient satisfaction, and the primary surgical approach's possible impact on revision. METHODS This retrospective study included all revision END-DCRs conducted at Kaplan Medical Center between the years 2002 and 2015. For long-term follow-up analysis, two subgroups of first and second revision END-DCRs with a minimum of documented 5-year follow-up after surgery were defined. Data were analyzed according to the primary surgical approach. Surgical success was defined by either anatomical (observed patent lacrimal flow) or functional (symptoms cessation) success. Patient satisfaction was measured by a questionnaire. RESULTS After exclusions, a total of 45 eyes from 38 patients who underwent revision END-DCR surgeries were included in the study. The yearly success rates from immediate to 5 years following the first revision were 93.3%, 75.5%, 71.1%, 68.9%, 68.9%, and 68.9% for the entire cohort, respectively. Immediate and 5-year success rates following the second revision were 88.8% and 77.8%, respectively. Primary END-DCR showed favorable 5-year success rates and patient satisfaction over primary external dacryocystorhinostomy (EXT-DCR) in both first and second revisions, but this did not reach significance. CONCLUSIONS Revision END-DCR carries an excellent short-term success rate, which decreases mainly throughout the first 2 years following surgery. Postoperative follow-up should be maintained within this timeframe. Revision END-DCR following either primary endoscopic or EXT-DCR produces comparable surgical outcomes and patient-reported satisfaction. LEVEL OF EVIDENCE 3b Laryngoscope, 131:E682-E688, 2021.

Abstract
The aim of this study is to assess the etiologic factors of primary dacryocystorhinostomy (DCR) failure according to DCR techniques and also to determine risk factors for the prediction of failure in revision external DCR. Retrospective review was performed in patients who underwent revision external DCR for previous DCR failure between 2008 and 2018. All patients underwent full ophthalmic and intranasal examination, lacrimal probing, and irrigation. Patients were classified into following groups according to previous DCR type: external, endoscopic endonasal, and transcanalicular laser DCR. Potential etiologic factors were compared between 3 groups. Multivariate analysis was performed to identify risk factors for failure in revision external DCR. About 115 eyes from 109 patients constituted the external (50.4%), endonasal (31.3%), and laser (18.3%) DCR groups. Among 27 (23.5%) patients with intranasal pathologies, septal deviation (33.3%) is the most common finding. The commonest cause of failure was inadequate ostium size in external (37.9%), endonasal (36.1%), and laser (66.7%) DCR groups. Inadequate ostium size and cicatricial lacrimal ostium scarring were observed significantly more common in the laser (P = 0.047) and external DCR group (P = 0.043), respectively. The success rate for revision external DCR was 85.2%. Canalicular or common canalicular obstruction (P = 0.032), intranasal pathology (P = 0.003), and bilateral obstruction (P = 0.025) demonstrated a significant independent association with failure in revision external DCR. Inadequate ostium size was the most common cause of failure in primary external, endonasal, and laser DCR. Canalicular or common canalicular obstruction, intranasal pathology, and bilateral lacrimal obstruction were significant predictors of failure in revision external DCR.

Abstract
Endoscopic DCR is an endonasal minimally invasive procedure to bypass an obstructed nasolacrimal duct by creating a direct fistula between the lacrimal sac and the nasal cavity. This is a retrospective case series review of the author's experience in endoscopic DCR in the period from 2007 to 2017. This series included 193 adult patients with a mean age of 47 years who underwent endoscopic DCR surgery. In this study, both primary and revision cases were reviewed including non-stented primary cases and bilateral simultaneous surgeries at the same session. Causes of failure in primary surgeries were stated, and indications of secondary cases were also reviewed. As a conclusion, endoscopic DCR remains the standard procedure in treating nasolacrimal duct obstruction with its consequent symptoms of epiphora, recurrent or chronic dacryocystitis.

Abstract
Background Although several studies have commented on causes of dacryocystorhinostomy (DCR) failure, detailed description of anatomical findings in such cases remains insufficient. Objective Our objective was primarily to analyze radiologic, endoscopic, and intraoperative findings in patients presenting with failed DCR and secondarily to assess the outcome of revision endoscopic DCR (endo-DCR) carried out at our institution. Methods Twenty-four failed DCRs presenting to our tertiary care center were retrospectively analyzed. Data collection included patients’ history, diagnostic, and management data, as well as thorough analysis of sinonasal CT scans, along with endoscopic and intraoperative findings. Outcome was also assessed in 21 cases with revision endo-DCR performed. Results The anterior part of uncinate process was not previously removed in 15 sides (62.5%), with unopened agger nasi in 13 sides (54.2%). The lacrimal bone was detected covering the posterior sac despite removal of the anterior ascending process of maxilla in 9 sides (37.5%). Rhinostoma was anterior to lacrimal sac in 2 sides (8.3%) and was below the sac in 7 sides (29.2%). Fibrous membrane covered the rhinostoma despite removal of all sac-overlying bones in 6 sides (25%). Other findings included intranasal adhesions, septal deviation, lateralized middle turbinate, granulation tissue, foreign body reaction, and chronic sinusitis. Nineteen of the 21 revision endo-DCRs were successful (90.5%). Conclusion This study provides a precise anatomical description of findings in cases of failed DCR. Such information is paramount in helping surgeons enhance their learning curve, refine the surgical technique, and improve patients’ outcome.

Abstract
OBJECTIVES To compare the causes of failure between external and endoscopic dacryocystorhinostomy (DCR) techniques for the treatment of lacrimal obstruction. STUDY DESIGN A retrospective cohort study. METHODS The study population consisted of 53 consecutive patients who underwent revision endoscopic DCR from 2002 to 2013 for lacrimal duct obstruction. Identified causes of previous DCR failure were compared between patients whose initial surgery was performed through an external versus an endoscopic approach. RESULTS Reasons for surgical failure after external (n = 21) versus endoscopic (n = 32) DCR included cicatricial closure of the internal lacrimal ostium (52.4 versus 53.1%; p = 0.96), inadequate removal of bone overlying the lacrimal sac (23.8 versus 9.4%; p = 0.15), sump syndrome (9.5 versus 9.4%; p = 0.99), and intranasal adhesions (65 versus 37.5%; p = 0.05). Adhesions that involved the middle turbinate were a particularly impactful cause of failure when the DCR was performed through an external versus the endoscopic approach (57.1 versus 28.1%; p = 0.04). Septoplasty was more likely to be needed at the time of revision surgery if the initial procedure was performed externally (71.1 versus 15.6%; p = 0.02). Surgical success rates for revision DCR were comparable between the groups (75.0% external versus 73.3% endoscopic; p = 0.90), with a mean follow-up of 12.7 months. CONCLUSION DCR failure associated with intranasal adhesions was more likely to occur when the surgery was performed through an external rather than an endoscopic approach. Endoscopic instrumentation allowed for identification and correction of intranasal pathology at the time of DCR, including an enlarged middle turbinate or a deviated septum, which may improve surgical outcome.

Abstract
BACKGROUND Endoscopic dacryocystorhinostomies (eDCRs) show patency rates between 81% and 94%. However, dacryocystorhinostomy (DCR) failure and the need for revision remain a significant challenge. One of the principal challenges in revision eDCR is the need to surgically identify the correct osteotomy site and maintain long-term patency in the setting of previously instrumented and potentially scarred tissue. At the same time, the surgeon must assume that the blood supply to the commonly described anterior and posteriorly pedicled flaps has been compromised. OBJECTIVE The objective of the study is to describe a novel flap technique for revision eDCR. METHODS The superior based mucosal flap is a novel technique that provides a vascularized mucosa preserving technique in revision eDCR despite previous instrumentation of the lacrimal system. This technique provides wide exposure of the revision osteotomy site while simultaneously allowing a viable mucosal flap to be replaced at the conclusion of the procedure, thereby minimizing bone exposure and cicatricial restenosis. RESULTS The authors have utilized this technique in 13 procedures with 100% positive identification of the lacrimal sac, a 0% complication rate, and a 100% success rate after a mean follow-up of 26.93 ± 10.33 months (range 6-35 months). CONCLUSION The eDCR using the superior pedicled mucosal flap provides excellent exposure of the maxillary bone and the lacrimal sac. This method preserves vascularity of the flap using a superiorly based pedicle which is typically inviolate during both open and endoscopic primary DCR. The mucosal flap can then be replaced, thereby minimizing bone exposure and optimizing patency.

Abstract
INTRODUCTION Secondary acquired nasolacrimal duct obstruction (SANDO), where the obstruction is caused by a known process, is becoming more commonly treated by endoscopic dacryocystorhinostomy (endoDCR). This study evaluates outcomes of endoDCR for cases of SANDO in comparison to endoDCR outcomes treating primary acquired nasolacrimal duct obstruction (PANDO). METHODS All patients undergoing endoDCR from 2006 to 2015 at a tertiary referral center were reviewed for etiology of nasolacrimal duct obstruction (NLDO) and success of procedure. Inclusion criteria were preoperative determination of NLDO via probing and irrigation, greater than 60-day follow up with assessment of duct patency via probing and irrigation after silicone tube removal, and postoperative survey for recurrent epiphora. Exclusion criteria were cases treating partial NLDO, patients undergoing concurrent conjunctivodacryocystorhinostomy, and patients lost to follow up or with incomplete records. Preanalysis stratification was performed for the following preexisting conditions: PANDO, granulomatosis with polyangiitis, sarcoidosis, midfacial radiotherapy, radioactive iodine therapy, severe prolonged sinusitis, prior failed DCR, and midface trauma. The primary outcome was postoperative anatomical patency of the nasolacrimal system with resolution of epiphora. Fisher-Freeman-Halton exact tests were performed comparing each SANDO group to the PANDO group with statistical significance set at p < 0.05. RESULTS Fifty-nine cases of NLDO underwent endoDCR in this series, 21 of which had a diagnosis consistent with SANDO. All patients treated with the aggressive perioperative management protocol the authors describe achieved anatomical patency. Patients with history of radioactive iodine therapy and radiotherapy had statistically worse outcomes compared with patients with PANDO, p = 0.011, p = 0.045, respectively. Stratified groups with increased intranasal sinus inflammation trended toward worse outcomes, but were not statistically different. CONCLUSIONS EndoDCR is a viable approach for the treatment of SANDO. In patients with history of radiotherapy or radioactive iodine therapy, however, endoDCR demonstrated decreased success rates as compared with patients with PANDO. Modifications of operative and postoperative management based on underlying etiology of NLDO may improve outcomes of endoDCR in SANDO cases. The authors describe an aggressive protocol for perioperative management of patients with pathologic nasal inflammation undergoing endoDCR.

Abstract
BACKGROUND To compare the frequency of appearance of complications, anatomical success and functional success after conventional endoscopic dacryocystorhinostomies (EN-DCRs) or EN-DCR with otologic T-Type ventilation tube combined with silicone tube intubation in repeated revision cases. METHODS Twenty-two patients who had epiphora and recurrent dacryocystitis after at least a previous failed revision DCR as well as 22 patients receiving conventional EN-DCR only were enrolled in the study between January 2008 and December 2011. Operations were performed by using an otologic T-tube combined with silicone tube intubation. Oral antibiotics, nasal steroids, oral antihistamines, and antibiotic eyedrops were given to all cases. The ventilation tubes were removed 6 to 20 weeks after surgery. RESULTS Of 22 cases, all cases achieved anatomical success, 19 cases were symptom free, and 3 cases had decreased continuation in complications with a functional success rate of 81.8%. The overall success rates were significantly higher than those in patients undertaking conventional EN-DCR only (P < 0.01). CONCLUSION The revision endoscopic DCR has a high rate of failure. The usage of a T-type ventilation tube can significantly improve the success rate of surgery. TRIAL REGISTRATION NUMBER ChiCTR-INR-17012160, retrospectively registered on July 27th, 2017.

Abstract
PURPOSE The aim of this study is to report the histopathological, Immunohistochemical, and ultrastructural features of a dacryocystorhinostomy ostium cicatrix. METHODS A prospective histopathological study was performed in a tertiary eye care setting. Scarred nasal mucosal tissues obtained during endoscopic revisions of 10 previously failed dacryocystorhinostomies secondary to complete cicatricial closure of the ostia were studied. The tissue specimens were analyzed using hematoxylin and eosin, periodic acid-Schiff staining. Special stains used include Masson's trichrome and Alizarin red. Immunohistochemistry was performed using vimentin, smooth muscle actin, CD3, CD5, and CD20. Specimens were processed for ultrastructural analysis as per standard protocols for transmission electron microscopy. RESULTS The respiratory epithelial regeneration was noted to be complete. Irregular laying of deeply eosinophilic and hyalinized collagen with intervening fibroblasts was noted. Focal areas of new bone formation were seen within the cicatricial tissue with osteocytes and ongoing osteoblastic rimming. The infiltrates were mixture of both T and B lymphocytes and were positive for CD3, CD5, and CD20 immunostaining. Electron microscopy showed disorganized collagen fibrils with numerous fibroblasts and mononuclear inflammatory infiltrate. Amorphous bony osteoid within a fibrillar background with metabolically active osteoblasts showed a vesicular cytoplasm, hyperplastic proliferating mitochondria, large Golgi apparatus, and dense endoplasmic reticulum. CONCLUSION There is new bone formation within the dense connective tissues of a dacryocystorhinostomy cicatrix. This study may provide useful inputs for further basic science studies aimed at better understanding of wound healing in failed dacryocystorhinostomy.

Abstract
Purpose The aims of this study were to report the preliminary experience of using telescopes, which were enabled for navigation guidance, and their utility in complex endoscopic lacrimal surgeries. Methods Navigation enabling of the telescope was achieved by using the AxiEM™ malleable neuronavigation shunt stylet. Image-guided dacryolocalization was performed in five patients using the intraoperative image-guided StealthStation™ system in the electromagnetic mode. The “look ahead” protocol software was used to assist the surgeon in assessing the intraoperative geometric location of the endoscope and what lies ahead in real time. All patients underwent navigation-guided powered endoscopic dacryocystorhinostomy. The utility of uninterrupted navigation guidance throughout the surgery with the endoscope as the navigating tool was noted. Results Intraoperative geometric localization of the lacrimal sac and the nasolacrimal duct could be easily deciphered. Constant orientation of the lacrimal drainage system and the peri-lacrimal anatomy was possible without the need for repeated point localizations throughout the surgery. The “look ahead” features could accurately alert the surgeon of anatomical structures that exists at 5, 10 and 15 mm in front of the endoscope. Good securing of the shunt stylet with the telescope was found to be essential for constant and accurate navigation. Conclusion Navigation-enabled endoscopes provide the surgeon with the advantage of sustained stereotactic anatomical awareness at all times during the surgery.

Abstract
Purpose: The purpose of this study was to evaluate the results of a teamwork revision endoscopic dacryocystorhinostomy (DCR) in eyes with previously failed external DCR. Methods: This retrospective study was performed on 50 failed external DCR subjects who underwent a teamwork revision endoscopic DCR by an ophthalmologist and an otolaryngologist. Paranasal sinus CT scanning was performed for each patient before the revision surgery. During surgery, any abnormal tissue noticed before silicone intubation was sent for pathological evaluation. Results: Endoscopic revision DCR was performed on 50 failed external DCR subjects with one-year follow-up. Of these, 31 were female (62%). The age range of the subjects was 18-88 years (mean: 59.98 years). Sinus CT showed at least one abnormality in 94% of cases. Revision endoscopy showed septal deviation (66%), scar formation (32%), ostium problems (28%), and sump syndrome (6%). Pathologic and clinical findings showed that chronic inflammation had a significant association with scar tissue and septal synechia (P = 0.001 and 0.008, respectively). At the final follow-up, anatomical and functional success was achieved in 45 out of 50 (90%) of subjects. Conclusion: Endoscopic revision DCR when performed as cooperation of otolaryngologists and ophthalmologists may help resolve the endonasal problems and increase the success rate.

Abstract
BACKGROUND The aim of this study was to report the outcomes of powered endoscopic dacryocystorhinostomy (PEnDCR) in patients with lacrimal sac within the sinus. MATERIALS AND METHODS Retrospective analysis was performed on all patients who underwent PEnDCR and were intraoperatively documented to have complete lacrimal sac in sinus. Data collected included demographics, clinical presentations, associated lacrimal and nasal anomalies, intraoperative findings, intraoperative guidance, complications, postoperative ostium behavior, and anatomical and functional success. A minimum follow-up of 6 months postsurgery was considered for final analysis. RESULTS A total of 17 eyes of 15 patients underwent PEnDCR using standard protocols, but with additional intraoperative guidance where required and careful maneuvering in the ethmoid sinus. The mean age of the patients was 37.2 (range 17-60) years. Of the unilateral cases, 69% (nine of 13) showed left-side predisposition; 80% of patients showed regurgitation on pressure over the lacrimal sac area. Associated lacrimal and nasal anomalies were observed in 13.3% (two of 15) and 40% (six of 15), respectively. At a mean follow-up of 6.6 months, anatomical and functional success were observed in 93.3% (14 of 15). One patient showed failure secondary to cicatricial closure of the ostium. CONCLUSION An entire sac within an ethmoid sinus poses a surgical challenge. Good sinus-surgery training, thorough knowledge of endoscopic anatomy, careful maneuvering, and use of intraoperative navigation guidance result in good outcomes with PEnDCR.

Abstract
Background The aim of this study was to assess the etiological factors contributing to the failure of a dacryocystorhinostomy (DCR). Patients and methods Retrospective review was performed in 100 consecutive patients who were diagnosed with anatomically failed DCR at presentation to a tertiary care hospital over a 5-year period from 2010 to 2015. Patient records were reviewed for demographic data, type of past surgery, preoperative endoscopic findings, previous use of adjuvants such as intubation and mitomycin C, and intraoperative notes during the re-revision. The potential etiological factors for failure were noted. Results Of the 100 patients with failed DCRs, the primary surgery was an external DCR in 73 and endoscopic DCR in 27 patients. Six patients in each group had multiple revisions. The mean ages at presentation in the external and endoscopic groups were 39.41 years and 37.19 years, respectively. All patients presented with epiphora. The most common causes of failure were inadequate osteotomy (69.8% in the external group and 85.1% in the endoscopic group, P=0.19) followed by inadequate or inappropriate sac marsupialization (60.2% in the external group and 77.7% in the endoscopic group, P=0.16) and cicatricial closure of the ostium (50.6% in the external group and 55.5% in the endoscopic group, P=0.83). The least common causes such as ostium granulomas and paradoxical middle turbinate (1.37%, n=1) were noted in the external group only. Conclusion Inadequate osteotomy, incomplete sac marsupialization, and cicatricial closure of the ostium were the most common causes of failure and did not significantly differ in the external and endoscopic groups. Meticulous evaluation to identify causative factors for failure and addressing them are crucial for subsequent successful outcomes.
