Navarro-Hernandez E, Galindo-Ferreiro A. Endocanalicular Laser Dacryocystorhinostomy and its modifications: A systematic review of techniques and success rates. ARCHIVOS DE LA SOCIEDAD ESPANOLA DE OFTALMOLOGIA 2022; 97:692-704. [PMID: 35879174 DOI: 10.1016/j.oftale.2022.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 03/08/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE the main objective of this work is to review the articles that refer to transcanalicular diode laser dacryocystorhinostomy (TCL-DCR) in acquired nasolacrimal duct obstruction (NLDO), as well as its modifications. MATERIAL AND METHODS A systematic review of publications related to TCL-DCR of the lacrimal duct from 2000 to March 2021 was carried out in the MEDLINE, EMBASE and COCHRANE LIBRARY databases. The search terms in Spanish and English were: «Endocanalicular laser», dacryocystorhinostomy or «primary DCR-L» or «laser» and «tear ducts». RESULTS After subjecting the articles to the inclusion and exclusion criteria, we got 49 articles: 21 retrospective and 28 prospective studies. The bibliometric result obtained guaranteed, for this review, a level C recommendation according to the Scottish Intercollegiate Guidelines Network scale. CONCLUSIONS Currently, the classic TCL-DCR has lower success rates than its modifications, so we suggest using the latter. We prefer TCL-DCR with IS-MMC or TCDL associated with endoscopy techniques, without being able to opt for any option, since their success rates are very similar. We leave the choice to the discretion of the surgeon, depending on the management skills of endonasal techniques. More studies, with longer follow-up, and better defined criteria are necessary to clarify which is the best TCL-DCR technique.

Comparison of outcomes of conventional transcanalicular laser dacryocystorhinostomy and modified transcanalicular laser dacryocystorhinostomy. Wideochir Inne Tech Maloinwazyjne 2018; 13:401-406. [PMID: 30302155 PMCID: PMC6174177 DOI: 10.5114/wiitm.2018.77054] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Accepted: 08/29/2018] [Indexed: 11/17/2022] Open
Abstract
Introduction Transcanalicular laser DCR (TL-DCR) approaches have been developed for the formation of a fistula between the nasal cavity and the lacrimal sac to ensure the continuity of the lacrimal drainage system over the years. However, the success rate of TL-DCR has varied widely. Aim To evaluate and compare the success rates of conventional transcanalicular multidiode laser dacryocystorhinostomy and modified transcanalicular multidiode laser dacryocystorhinostomy. Material and methods Ninety-one eyes of 91 adult patients admitted with epiphora and diagnosed with chronic dacryocystitis were included in the study. The participants were divided into two groups. Group 1 consisted of 55 patients who were treated with conventional transcanalicular laser dacryocystorhinostomy. Group 2 consisted of 36 patients to whom the same surgical procedure was applied with the difference of nasal mucosa excision prior to laser osteotomy. The groups' intraoperative surgical ostium size, perioperative and postoperative complications, operative times and success rates were compared. Results The mean follow-up periods for each group were 8.88 ±2.99 months and 10.28 ±4.47 months, respectively (p = 0.077). Intraoperative mean surgical ostium sizes were 31.85 ±14.98 mm2 and 42.25 ±18.09 mm2, respectively (p = 0.004). The mean operation time in group 1 was significantly shorter compared to group 2 (18.55 ±4.05 min and 24.44 ±3.18 min, respectively, p = 0.0001). The overall success rate was 65.45% in group 1 and 75.00% in group 2 (p = 0.335). Conclusions Although the surgical ostium area was significantly greater in group 2, there was no significant difference in surgical success and patient satisfaction rates between the two groups.

Abstract
Background Success rates for revision dacryocystorhinostomy (DCR) are lower than primary DCR. Scarring of the sac may limit the ability of the surgeon to achieve good nasal and lacrimal mucosa apposition. This study evaluates the comparative success rates of the external and endoscopic techniques for revision DCR. Methods Seventeen consecutive revision endoscopic DCRs (average age, 60.9 years) and 13 revision external DCRs (average age, 65.1years) performed from January 1999 to December 2000 performed by separate surgeons were entered into the study. Patients with functional nasolacrimal and canalicular obstruction were excluded. The average follow-up was 11.1 months for the endoscopic DCR group and 10 months for the external DCR group. Results A successful DCR required complete relief of symptoms and an endoscopically determined anatomic patency of the nasolacrimal system. Revision endoscopic DCR surgery was successful in 76.5% of cases (13 of 17 cases) and external DCR surgery was successful in 84.6% (11 of 13 cases). This difference was not statistically significant. (p = 0.64, Fisher exact test with a two-tailed probability). Conclusion Revision endoscopic DCR has a success rate of 76.5%, which compares favorably with that of the revision external DCR (84.6%).

Abstract
This article compares the efficacy of transcanalicular laser assisted dacryocystorhinostomy (TL DCR) with conventional external dacryocystorhinostomy (Ex DCR). All patients were randomly divided into two groups - Group A included patients who underwent TL DCR and Group B included patients who underwent Ex DCR. 168 operations were done in a total of 163 patients; 79 patients in group A and 84 patients in group B. The overall success rate was 90.12% in group A and 95.40% in group B. The mean total surgical time was 17.41 min in group A and 49.49 min in group B. The duration of stay in hospital was about 3 hours for group A and about 48 hours for group B. Intra and post operative complications were more in group B than in group A. TL DCR can offer a minimally invasive technique with comparable results and better patient satisfaction than Ex DCR.

Abstract
PURPOSE To report the outcomes of transcanalicular diode laser-assisted revision surgery for failed dacryocystorhinostomy with/without distal or common canalicular obstruction. METHODS The medical records and recorded videos of consecutive transcanalicular diode laser-assisted revision surgeries performed for failed dacryocystorhinostomy between May 2011 and May 2015 were reviewed. Cases of unavailability of video and cases lost to follow up after surgery were excluded from the study. With respect to the level of obstruction, lacrimal drainage systems were divided into Group 1 (obstruction at the level of the ostium) and Group 2 (obstruction at the level of the distal or common canaliculus). Data associated with anatomical and functional success were analyzed. RESULTS Revision dacryocystorhinostomy surgeries were performed on 68 patients during the study period. Transcanalicular diode laser-assisted revision surgeries were performed on 48 eyes of 39 patients. Mean follow-up period after revision surgery was 13.3 ± 12.6 months. Overall, anatomical success rate was 83.3% (40/48) and functional success rate was 68.8% (33/48). Anatomical success rates and functional success rates in the 2 groups showed no significant difference (80.0% [24/30] vs. 86.7% [13/15], p = 0.699; 70.0% [21/30] vs. 66.7% [10/15], p = 1.000, respectively). CONCLUSIONS Transcanalicular diode laser-assisted revision surgery may be an alternative technique for failed dacryocystorhinostomy. Distal or common canalicular obstruction did not affect the outcomes of revision surgeries.

Abstract
INTRODUCTION This study aimed to evaluate the short and long-term results of endoscopic dacryocystorhinostomy (DCR) with and without silicone stenting in chronic dacrocystorhinitis due to postsaccal blockage. METHODS The study involved a case series of consecutive 89 patients (128 eyes) who underwent endoscopic DCR. All patients were operated on by the senior author. The stent group comprised 63 eyes (44 patients), for which the DCR was performed between September 2002 and September 2005. The non-stent group with 65 eyes (45 patients) underwent the DCR between October 2005 and December 2006. The follow-up duration was up to 33 months after surgery. The statistical significance (p-value) was calculated using the chi-squared test. RESULTS The short-term success rate at six months' follow-up was 70% in the stent group and 97% in the non-stent group (p=0.0005) while the long-term success rate at 33 months was only 57% in stent group compared with 89% in the non-stent group (p=0.0003). CONCLUSIONS In this study, the non-stent group showed a higher success rate than the stent group on both short and long-term follow-up. Our study suggests that postoperative stents are not necessary for primary DCR and may be associated with a worse outcome.

Abstract
AIM To compare a composite technique of endoscopic dacrocystorhinostomy with the conventional technique. METHODS A randomised prospective study was carried in the department of Otolaryngology Maulana Azad Medical College. Thirty patient selected for Endoscopic DCR were divided into two groups, one of which underwent conventional endoscopic DCR and the other group were treated with a newer technique using cautery, cold instrumentation and laser at different steps of endoscopic DCR. The patients were followed up for nine months. RESULTS/CONCLUSION By using cautery, cold instrumentation and laser at different steps of endoscopic DCR we were able to achieve a success rate of around 94% with this composite technique as compared to 83.3% in conventional endoscopic DCR surgery.

Abstract
Purpose. To compare the efficacy of endonasal endoscopic dacryocystorhinostomy and endocanalicular diode laser dacryocystorhinostomy. Materials and methods. A total of 126 dacryocystorhinostomies were performed in 111 patients with epiphora. In 55% of cases (69/126) we performed an endonasal endoscopic dacryocystorhinostomy and in 45% (57/126) we carried out an endocanalicular dacryocystorhinostomy using diode laser. The mean age at diagnosis was 63 years. The mean age was higher in the endocanalicular group than in the endonasal endoscopic group: 64 versus 62 years. There were 25 men (23%) and 86 women (77%). Results. Successful results were achieved in 73% of patients (92/126). In the endonasal endoscopic group, 83% of patients (57/69) were symptom free compared to 62% of patients (35/57) in the laser diode group. A bicanalicular nasal silicone tube was left in place for a mean of 2.32 months in the endoscopic endonasal group and for 2.82 months in the laser diode group (p=0.164). Median time of recurrence after removal of the tube was 3.56 months (range 0-9.6): 2.84 months in the laser diode group and 4.87 months in the endonasal endoscopic group (p=0.069). Conclusions. The endonasal endoscopic approach achieved better results for nasolacrimal obstruction than the endocanalicular laser diode technique.

Abstract
PURPOSE To describe current surgical techniques of dacryocystorhinostomy (DCR) and to compare their effectiveness by analysing the advantages and disadvantages between external, endonasal and transcanalicular surgery. PATIENTS AND METHODS A total of 91 DCRs were analysed using a retrospective, cross-sectional and multicentre study in 75 patients who had symptoms of nasolacrimal duct obstruction. Of these, 28 were operated using external DCR, 31 endonasal technic, and 32 transcanalicular DCR with diode laser. Outcomes were evaluated subjectively using patient symptoms for the grade of epiphora and the results from the syringing before and after surgery. RESULTS External DCR was performed in 28 cases, with 19 cases asymptomatic (67.85%), and 20 patients had a patent tract (71.42%). Endonasal DCR was performed in 31 cases, of which 19 cases were asymptomatic (61.29%), and 21 showed patency of the nasolacrimal duct (67.74%). A transcanalicular technique was performed in 32 cases, with absence of epiphora in 24 patients (75%), and the syringing was successful in 24 of them (75%). CONCLUSIONS Any of these 3 surgery techniques would be an adequate treatment for lacrimal obstruction, due to the significant development of endonasal and transcanalicular techniques in recent decades. With improvement, we could use either endonasal or transcanalicular techniques with diode laser with the same lever of effectiveness as the classic external approach, with the advantages of minimally invasive surgery.

Abstract
We report the success rate and problems associated with conventional dacryocystorhinostomy (DCR) in failed cases of Trans-canalicular, laser-assisted DCR (TCLADCR). Out of 50 patients operated by the TCLADCR technique during the period 2005 – 2006, 33 patients had failure, which was confirmed on syringing of the nasolacrimal passage. Before considering them for conventional DCR, a thorough ear, nose, throat (ENT) examination was done by an ENT surgeon, to rule out a nasal pathology. All the patients were operated by the conventional standard DCR method at a medical college. While performing the surgery, the problems that came across were identified and noted. The success rate was found to be 91% in this study in a follow-up period of one year, with no major intra-operative problems. Conventional DCR is still a gold standard and should be considered as a procedure of choice in failed cases of TCLDCR.

Abstract
OBJECTIVE In the current study, whereas the results of endoscopic primary and revision endoscopic dacryocystorhinostomies (END-DCR) were evaluated, the success rates in patients who did or did not undergo nasal surgery were also compared. METHODS A retrospective medical record review of 70 patients (with a total of 72 affected cases) who were admitted to our clinic with a primary complaint of epiphora between January 2002 and July 2009 was performed. Patients who required additional nasal procedures were also included in the analysis. A successful DCR was defined as relief of symptoms on testing with irrigation at the last follow-up visit. RESULTS The success rates were 82.1% (23/28 DCRs) in the primary END-DCR group and 84.1% (37/44 DCRs) in the revision END-DCR group. There were no significant differences between the groups regarding overall surgical success rates (P = 0.829). The need for additional nasal surgery was significantly higher in the revision cases (52.3%) than the primary cases (28.6%; P = 0.048). No significant difference regarding success rates existed between the patients who required an additional septoplasty or ancillary sinus surgery and the patients who did not have nasal pathology and underwent END-DCR alone (P = 0.456). The mean follow-up period was 11 months in the revision END-DCR group and 8 months in the primary END-DCR group. CONCLUSIONS Endoscopic DCR should be considered as the treatment of choice in cases with intranasal pathologies. Endoscopic DCR is a safe and effective procedure in revision cases, as well as in primary cases.

Abstract
OBJECTIVE To evaluate the clinical outcome and efficacy of endocanalicular laser dacryocystorhinostomy using a multidiode laser in cases unresponsive to medical therapy, probing or intubation of pediatric nasolacrimal duct obstruction. METHODS Eight children with nasolacrimal duct obstruction were treated with a multidiode laser. The study was prospective, non-randomized, and noncomparative. The patients, 2 (25%) males and 6 (75%) females, ranged in age from 8 to 13 years (mean 11.25±2.43). Surgery was performed under general anesthesia. All procedures were performed using a multidiode laser. The nasal passage was visualized with a 30° nasal video endoscope. In all cases, silicone stents were inserted. The main outcome measure was resolution or improvement of the epiphora and no major laser damage intranasally. Patients were followed for at least 6 months. RESULTS The endocanalicular laser dacryocystorhinostomy failed in one of the 8 (12.5%) cases, which had been secondary to trauma. The others were due to primary nasolacrimal duct obstruction. External dacryocystorhinostomy was performed on the failed case. None of the cases with primary nasolacrimal duct obstruction had obstruction after the endocanalicular laser dacryocystorhinostomy operation. CONCLUSIONS Endocanalicular laser dacryocystorhinostomy using a multidiode laser appears to be an effective technique in cases unresponsive to medical therapy, probing or intubation of primary nasolacrimal duct obstruction.

Abstract
Objective: We present a prospective, non-comparative case series study of 126 consecutive diode laser-assisted transcanalicular dacryocystorhinostomy (TCL-DCR) procedures on 122 patients. We analyzed success rate, procedure time and amount of laser energy needed for a 5 mm osteotomy. Materials and Methods: One hundred and twenty-two patients with nasolacrimal duct obstruction were included in the study. The procedure was performed under general anesthesia, and the nasal mucosa was anesthetized. An endoscope was used for examination of the lacrimal pathways. The site of osteotomy was determined with transillumination of the lateral nasal wall. We achieved osteotomy by applying laser energy via an optic fiber. We used a 980 nm diode laser with power of 10 Watts. We inserted a bicanalicular silicone stent as the last step. Success of procedure was absence of epiphora (subjective), or patency of the lacrimal drainage system on irrigation (objective). Results: We performed 126 successive endoscopic laser (EL-DCR) with bicanalicular intubation in 122 patients. The average procedure time was 12 min, and on average 245 Joules of laser energy was needed. The silicone stents were removed three to eight months after surgery. We observed absence of epiphora and a patent nasolacrimal duct on irrigation in 105 out of 126 treated eyes. Eighteen patients had epiphora despite a patent nasolacrimal duct on irrigation. This yields a success rate of 83.3%, with an average follow-up period of 12 months. Conclusions: The 980 nm EL-DCR with bicanalicular intubation is a new contribution to the field of lacrimal surgery. It is a minimally invasive quick procedure yielding a high success rate.

Abstract
PURPOSE To report the results of transcanalicular-endonasal revision dacryocystorhinostomy (DCR) with a semiconductor diode laser in cases of failed external DCR. DESIGN Prospective, nonrandomized, interventional case series. METHODS Fifteen cases in 13 patients with failed external DCR underwent transcanalicular-endonasal DCR with a semiconductor diode laser. A functional successful outcome was defined as a patent nasolacrimal drainage system in nasolacrimal irrigation and a resolution of the symptomatic epiphora and/or mucoid discharge. RESULTS The patients were followed for a mean postoperative period of 27.3 months (range, nine to 54 months). The mean duration of the surgery was 19.6 minutes. After the initial revision transcanalicular-endonasal DCR surgery, patency to irrigation was obtained in 12 cases (80%), and 15 cases (100%) after a second revision treatment. Three cases required repeated revision surgery, and three other cases were considered to be functional failures in spite of a patent lacrimal system after the final revision surgery. The overall functional success rate was 80% (12 cases) at the final examination (mean, 27.3 months after surgery), and there were no intraoperative and postoperative complications. The presence of a canalicular obstruction or granulation tissue was not significantly related to the success rates of the revision surgery. The length of time between the primary and revision surgery, gender, age, the duration of the first revision surgery, and the timing of stent removal were also not significantly related to the failed cases. CONCLUSION Transcanalicular-endonasal DCR is a minimally invasive procedure and is recommended for patients as an alternative procedure for failed external DCR.

Abstract
PURPOSE To evaluate the effectiveness of transcanalicular dacryocystorhinostomy with diode laser in treatment of epiphora in adults. METHODS A prospective, noncomparative, interventional case series of transcanalicular dacryocystorhinostomy in 25 patients presenting with epiphora due to nasolacrimal obstruction. Patient age ranged from 32 to 72 years. Patients were evaluated postoperatively at 12, 24, and 36 months. Patients were evaluated for symptom improvement through a visual analog scale, and patency of osteotomy by lacrimal system irrigation with fluorescein and direct visualization by nasal endoscopy. Success was defined as resolution of epiphora. RESULTS Transcanalicular dacryocystorhinostomy was able to re-establish patency of the lacrimal system in 88% of cases after 36 months of surgery. No differences were found between patients older than 65 years and younger patients (chi-square, p > 0.05). Early (12 months) and late (36 months) results were similar (chi-square, p > 0.05). CONCLUSIONS In this prospective series, transcanalicular dacryocystorhinostomy was effective in treatment of epiphora in adults with little morbidity.

Abstract
PURPOSE To determine the safety and efficacy of the diode laser with intraoperative mitomycin C in endocanalicular laser dacryocystorhinostomy (ECL-DCR). METHODS In a prospective case series of 40 ECL-DCRs using the diode laser, mitomycin C was placed intraoperatively in all cases. The main outcome measure was resolution or improvement of epiphora and no major laser damage intranasally. Patients were followed for at least 18 months. RESULTS Forty consecutive ECL-DCRs on 30 patients (23 females, 7 males, mean age 62 years) were performed from April 2000 to December 2001. The success rate at 12 months postoperatively was 87.5%. All failures were due to a constricted nasal osteotomy. No significant intraoperative or postoperative complications were recorded. CONCLUSIONS Diode laser ECL-DCR with mitomycin C appears to be a safe and effective treatment modality for primary acquired nasolacrimal duct obstruction.

Abstract
In summary, this project proposes to explore the feasibility of a new temporary implant and surgical technique to improve the DCR procedure. This is a significant improvement over current DCR practice for the following primary reasons: (1) it eliminates the risk of injury to both the eye and upper lacrimal system; (2) it permits tear flow into the nose immediately following surgery, potentially 6 months earlier than current practice and procedure, which frequently does not re-establish normal tear flow until stents are removed. Plans have been made to implant stents of different sizes and proportions into cadavers in order to test implantation and removal of the stent via external and intranasal approaches.

Abstract
BACKGROUND The aim of this study was to investigate the results obtained by intranasal dacryocystorhinostomy. METHODS 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. RESULTS 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. INTERPRETATION 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.

Abstract
PURPOSE To describe the outcomes of endocanalicular laser dacryocystorhinostomy (ECL DCR) for patients with nasolacrimal duct obstruction (NLDO). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS One hundred eight consecutive patients who underwent ECL DCR. METHODS The records of the patients who underwent ECL DCR at 1 of 2 academic centers were reviewed and the data analyzed. MAIN OUTCOME MEASURES Success was defined as the resolution of symptoms or unobstructed lacrimal irrigation. RESULTS One hundred eighteen consecutive ECL DCR surgeries performed on 108 patients between June 1997 and June 2003 were reviewed, excluding 6 lost to follow-up. Endocanalicular laser DCR was the initial surgical intervention for all cases except 6 that had previously undergone surgery (external or endonasal DCR) at outside hospitals. Twenty-seven of the surgeries were considered failures on the basis of recurrent epiphora or discharge, or reflux on nasolacrimal irrigation. One of the failures was permanently corrected with balloon dacryoplasty. Nine of the other failures had a repeat procedure, with 7 remaining patent after one repeat procedure and an additional one remaining patent after a third procedure. All 6 ECL DCR procedures that were performed after external or endonasal DCR at an outside institution remained patent. Among the 102 initial lacrimal surgeries in this series, there was a 73.6% success rate. The overall success, including repeat procedures, was 81.5%. The success of this technique as a repeat procedure after previous external, endonasal, or ECL DCRs was 87.5%. CONCLUSIONS Endocanalicular laser DCR offers a minimally invasive alternative procedure for the treatment of NLDO. In our series, the success rates are comparable to those previously reported. The technique had a high success rate when used to treat recurrent NLDO after previous lacrimal surgery.

Abstract
PURPOSE To compare success rates of external dacryocystorhinostomy (DCR) and endoscopic endonasal DCR for acquired nasolacrimal duct obstruction (NLDO). DESIGN Retrospective, comparative, nonrandomized clinical study. PARTICIPANTS One hundred forty-three patients (176 surgeries) operated for acquired NLDO. METHODS A review of electronic medical records of patients with acquired NLDO who underwent DCR at the Jules Stein Eye Institute from 1999 to 2004 was performed. Data regarding the lacrimal drainage system, comprehensive eye examination, surgical outcome, and postoperative nasal endoscopy were analyzed. MAIN OUTCOME MEASURES Surgery failure was defined as (1) no marked improvement in tearing or any episode of postoperative dacryocystitis, (2) inability to irrigate the lacrimal system postoperatively, and (3) postoperative nasal endoscopy with scarring in the intranasal osteotomy or no visualization of fluorescein dye. Postoperative nasal endoscopy was performed in all failed cases and in >50% of all patients. RESULTS One hundred forty-three patients (48 male and 95 female; mean age, 63 years) underwent 176 DCR surgeries for acquired NLDO. Success was achieved in 135 cases (76.7%), and failure in 41 (23.3%). Of the 41 failed cases, anatomical obstruction at the fistula site was found in 20 (49% of failed cases), whereas functional failure with no evidence of obstruction was found in 21 (51%). Surgery revision was performed in 22 cases (12.5%), but it was successful in only 9 (5.1%); patients who failed the first revision were likely to fail additional revisions (P = 0.02). History of facial trauma was associated with surgery failure. In our patients, endoscopic DCR (86 cases) had a significantly higher success rate than external DCR (90 cases), 84% versus 70% (P = 0.03). Complications included 1 patient with nose bleeding on the first postoperative day that resolved with nasal packing and 2 patients with sump syndrome that resolved after endoscopic revision. CONCLUSIONS The success rate of DCR for acquired NLDO in our group of patients was 77%, lower than reported in previous studies, with endoscopic surgery showing better results. Success rates of revision surgery were relatively low (<50%), and patients who fail the first revision are not likely to benefit from additional revisions.

Abstract
INTRODUCTION The aim of this paper is to highlight the use of the Holmium YAG laser in the endoscopic placement of Lester Jones tubes in patients with a blocked canaliculus or failed lacrimal pump function. MATERIALS AND METHODS Sixteen cases with a non-functional canaliculus were included over a one-year period. Following caruncle excision, a 19 G needle is inserted through the medial canthal tissues into the nasal space. Nasal endoscopy confirms the accurate positioning in relation to the nasal anatomy. With the Holmium YAG laser, a tissue channel is fashioned around the guide needle through the structures of the lateral nasal wall to facilitate an accurate and secure placement of the Jones tube. RESULTS The endoscopic, laser-assisted placement reduces the operating time to less than 20 minutes, minimizes tissue trauma and does not require the initial surgical steps of an open DCR procedure. There were 14 cases (87.5%) with securely retained tubes and two cases (12.5%) that required tube replacement. The advantage of the procedure is especially great in revision surgery where the ostium is opened through scar tissue. CONCLUSIONS Nasal endoscopy with the assistance of the Holmium YAG laser offers simplicity and precision in the placement of Jones tubes. It minimizes tissue trauma and increases the surgical success rate.

Abstract
PURPOSE To compare the success rates of a new mechanical endonasal dacryocystorhinostomy (MENDCR) technique and the conventional external dacryocystorhinostomy technique (Ext-DCR). METHODS A prospective, nonrandomized interventional comparative case series of 31 consecutive MENDCRs and 24 Ext-DCRs performed from January 1999 to December 2000. Patients with anatomic nasolacrimal duct obstruction were included in the study; previous lacrimal surgery and functional nasolacrimal and canalicular obstruction were exclusion criteria. Two surgeons performed the MENDCRs, using a standardized operative technique, which involved creation of a large bony ostium and mucosal flaps between the lacrimal sac mucosa and nasal mucosa. One surgeon performed all Ext-DCRs. RESULTS Twenty-seven patients (8 men, 19 women) underwent 31 MENDCRs. The average age of the patients was 62.9 years (range, 15 to 86 years; SD, 19.1 years). In 11 cases (35.4%), a septoplasty was required at the time of surgery, and in 6 cases (19%), further endoscopic sinus surgery was performed. In the Ext-DCR group, 23 patients (7 men, 16 women) underwent 24 DCRs. The average age was 59.6 years (range, 22 to 86 years; SD, 18.5 years). No other nasal procedures were performed at the time of surgery in this group. The average follow-up time was 13 months for the MENDCR group and 12.4 months for the Ext-DCR group. Success was defined as relief of symptoms and by anatomic patency, which was assessed by history, fluorescein flow on nasal endoscopy, and lacrimal syringing. In the MENDCR group, surgery was successful in 29 of 31 DCRs (93.5%); 1 of 2 failed cases was anatomically patent but symptomatic, yielding an anatomic patency rate of 96.8%. In the Ext-DCR group, the success rate was 95.8% (23/24 DCRs); the failed case was anatomically patent but symptomatic, giving an anatomic patency rate of 100%. The differences in overall success and anatomic patency were not statistically significant (P = 0.6 and P = 0.56, 1-tailed Fisher exact test). CONCLUSIONS The success rate of MENDCR (93.5%) compares favorably with that of standard external DCR (95.8% in this study). MENDCR relies on the creation of a large ostium and mucosal flap apposition. A larger, randomized prospective trial is needed to fully assess the efficacy of this new technique.

Abstract
AIM The aim of this study was to assess the success rate of bicanalicular intubation of lacrimal drainage apparatus in chronic dacryocystitis patients who were at high risk of failure of surgery of dacryocystorhinostomy. MATERIAL AND METHODS A total of 24 patients with chronic dacryocystitis (25 eyes) including 11 males and 13 females (age range 3-80 years) having high risk factors of failure of dacryocystorhinostomy were enrolled. Factors such as previous attacks of acute dacryocystitis, trauma in lacrimal sac region, previously failed dacryocystorhinostomies, formation of false passages in the lacrimal drainage apparatus were considered. Conventional dacryocystorhinostomy followed by bicanalicular intubation of the lacrimal drainage apparatus with Jain metal silicone the lacrimal intubation tube (20-23 gauge) was performed in all these patients. The patients were followed up at weekly intervals for two months, at 6 months and at 1 year post surgery. RESULTS A total of 25 eyes in 24 patients (including 11 males and 3 females) were operated upon using the technique of bicanalicular intubation of lacrimal drainage apparatus with conventional external dacryocystorhinostomy. The procedure was successfully performed in 22 out of the 25 eyes. Perioperative complications included punctual damage due to recurrent attempts at passing these probes in 2 patients and mild damage to nasal mucosa in 5 patients. The majority of patients did not experience any untoward symptoms from these silicone tubes. However, in three eyes there was felt a mild foreign body sensation and two patients had chronic conjunctival erythema. The tubes could not be retained in two of these three eyes. Additionally, in one eye there was spontaneous extrusion of tubes whilst sneezing 3 months after surgery. All these three eyes had a recurrence of symptoms due to non-retention of the tubes and needed re-operation. On average the tubes were retained for a period of six months before they were spontaneously extruded or removed. Fifteen patients retained the silicone tubes for more than 1 year. The procedure gave a success rate of 76% (19/25 eyes) and these were the eyes in which the tubes had been retained for more than 6 months. The success was not influenced by the age or sex of patient, laterality of eye, aetiology of chronic dacryocystitis, or evidence of bony deformity or abnormality of the sac. CONCLUSIONS Bicanalicular intubation for lacrimal drainage system is a simple, inexpensive and straight forward adjunct to conventional external dacryocystorhinostomy. The procedure is strongly indicated for patients with chronic dacryocystitis who are at high risk of surgical failure. Carefully performed, it gives a 76% success rate and is not influenced by the different variables examined.

Abstract
We will refer to lacrimal system pathologies involving the outflow pathways, as well as to the recent advances in the management of canalicular and lacrimonasal duct anomalies, including modifications to dacrycystorhinostomy technique, treatment for congenital obstructions, and lacrimal intubations. Special emphasis will be placed on the usefulness of nasal and canalicular endoscopy for the examination and treatment of congenital obstructions and endonasal pathologies, as an aid for intubations and lacrimal surgery, as well as on reasons for failed procedures.

Abstract
AIMS To utilise the improved optical qualities of newly developed lacrimal endoscopes and newly miniaturised laser fibres for diagnostic visualisation and laser surgery of the lacrimal system. METHODS A KTP laser (wavelength 532 nm, 10 W energy) was used for laser assisted dacryocystorhinostomy (DCR) with endolacrimal visualisation in 26 patients. Bicanalicular silicone intubation was placed in all patients for at least 3 months. RESULTS After 3-9 months of follow up, the silicone tube in all 21 patients who underwent KTP laser DCR are still patent, three patients have eye watering in extremely cold weather and two required a conventional DCR. CONCLUSIONS The KTP laser generates enough power to open the bony window in DCR surgery. Precise endolacrimal visualisation via a specially designed miniendoscope is essential for surgical success.
