Abstract
Study aims to assess the postoperative ostium shrinkage pattern and also attempted to evaluate various ostium parameters and their impact on surgical outcome by using DOS scoring system. Prospective study comprising 44 patients of NLD obstruction with 52 procedures performed during October 2016 to November 2018. Various dimensions of bony neo-ostium were recorded intraoperatively and during 1st, 3rd and 6th month follow up. Degree of ostium shrinkage and its correlation with anatomical and functional success was studied. DCR ostium (DOS) scoring system, comprised of ten various ostium parameters, was used to evaluate postoperative ostium. Intraoperative mean ostium height and width were 13.67 ± 2.76 mm and 7.0 ± 1.94 mm and surface area was 98.33 ± 38.46 mm2. Maximum ostium shrinkage (by 66.93%) occurred at 1 month and after which, average size of ostium was quite stable with little change. The anatomical and functional success rate was 94.23% and failure rate was 5.77%. DOS score was "excellent" in 40(75.92%), "good" in 9(17.31%) and "poor" in 3(5.77%) cases. Meticulous evaluation at regular intervals is important for surgeon to understand the characters of ostium during healing and also helps in early detection of pathologies and may facilitate early corrective intervention. We believe that DOS system provides an effective protocol to standardize the ostium evaluation. The ostium parameters with favourable surgical outcome are ostium location anterior to axilla of MT, circular/ oval shape with shallow base, size > 8 × 5 mm, clearly visualized and dynamic ICO, absence of ostium cicatrization, granulomas, synechiae and other pathologies.

Torun MT, Yılmaz E. The role of the rhinostomy ostium size on functional success in dacryocystorhinostomy. Braz J Otorhinolaryngol 2021; 88 Suppl 1:S57-S62. [PMID: 33888431 PMCID: PMC9734259 DOI: 10.1016/j.bjorl.2021.03.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 01/13/2021] [Accepted: 03/15/2021] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION Endonasal and external dacryocystorhinostomy procedures have both been used for the treatment of post-saccular obstruction of the lacrimal system. Functional success of these surgeries depends on several factors. OBJECTIVE To evaluate the status of the rhinostomy ostium with endonasal and external approaches in dacryocystorhinostomy operations and to determine the effect of ostium size on postoperative functional success. METHODS The charts of the patients operated in our hospital between May 2017 and January 2019 were analyzed retrospectively (ethical approval number: 2018-12.04). The patients that were operated in the ophthalmology and otolaryngology departments were included in the study. Endoscopic rhinostomy ostium measurements, punctum lavage findings and complications were recorded at 8 weeks postoperative at the earliest. RESULTS When the 64 patient charts were reviewed (76 operations), the mean ostium width was 1.85±1.11mm in the endonasal approach group and 3.60±2.24mm in the external approach group. The mean ostium areas in endonasal and external group were 14.61±16.66mm2 and 56.05±60.41mm2, respectively. The ostium was anatomically patent and punctum lavages were negative in 11 patients (6 patients in the endonasal approach group and 5 patients in the external approach group) and these cases were considered as functional failures. The rhinostomy ostium was significantly wider in the external approach group, but this was considered ineffective on functional outcomes. CONCLUSION Lacrimal duct stenosis can be successfully treated with endonasal and external methods. Tear drainage may be insufficient even in the presence of a patent ostium. Therefore, functional success should also be considered when evaluating the overall success of dacryocystorhinostomy. An anatomically patent ostium is definitely required, while it is believed that ostium size does not affect functional surgical success.

Evaluation of ostium size following endoscopic dacryocystorhinostomy as a predictive factor of outcome: A prospective study. J Fr Ophtalmol 2020; 44:397-403. [PMID: 33388192 DOI: 10.1016/j.jfo.2020.05.024] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 05/12/2020] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Endonasal dacryocystorhinostomy (DCR) is a surgical procedure that aims to increase tear drainage to treat epiphora caused by nasolacrimal obstruction by creating a bypass through the bone between the lacrimal sac and the nasal cavity. A silicone stent is temporarily put in place for 2 months to avoid early obstruction of the rhinostomy. One of the causes of surgical failure is related to progressive stenosis of intranasal ostium, due to fibrosis and new bone growth, inducing a relapse of epiphora and/or dacryocystitis. Few studies have described changes in the size of the intranasal ostium on direct post-DCR measurement or kinetics of its shrinkage. The purpose of this study is to determine whether changes in the size of intranasal ostium might be a predictor of final functional efficacy. MATERIALS AND METHODS A prospective cohort of eighteen consecutive patients undergoing endonasal DCR for chronic epiphora or chronic dacryocystitis between January 2017 and April 2018 was analyzed. Eight patients who underwent bilateral DCR, and twenty-six intranasal ostia were finally analyzed. Follow-up took place every two months for 1 year, with the silicone tube removed at 2 months. Functional success was defined as absence of recurrent epiphora or dacryocystitis. Ostium size was systematically measured on photos taken during intranasal endoscopy performed every 2 months for 1 year. RESULTS At 2 months after endonasal DCR, 23 of the 26 ostia (88.5%) were functional, but only 19 (73.1%) of them were directly measurable. The mean horizontal diameter at 2 months was 1.44 (SD 0.61) mm, and the mean vertical diameter was 0.86 (SD 0.37) mm, which corresponded to a mean area of 10 (SD 0.84)mm2. We noted a statistically significant decrease in ostium size and area between 2 and 4 months after the procedure (P -0.001), followed by a stabilization period with no statistical correlation between the size of the ostium and its final functional efficacy. At 6 months after DCR, of the 7 ostia that were not initially measurable, 3 were immediately non-functional at 2 months, 3 had a relapse of epiphora at 4 months, and 1 had a relapse of dacryocystitis at 6 months, i.e., 100% clinical failures at 6 months. The other procedures all remained functional after 1 year of follow-up. CONCLUSION The intranasal ostium of an endonasal DCR shrinks significantly within the 2 months after removal of the silicone tube and remains stable thereafter. There is no correlation between the size or area of intranasal ostium and its final functional efficacy. However, when the ostium is not measurable at the time of 2-month stent removal, all patients experienced a relapse of epiphora or dacryocystitis within 6 months.

Comparative study of stenting and ostium packing in Endoscopic Dacryocystorhinostomy for Primary Acquired Nasolacrimal Duct Obstruction. Sci Rep 2020; 10:46. [PMID: 31913338 PMCID: PMC6949294 DOI: 10.1038/s41598-019-57019-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 12/09/2019] [Indexed: 11/09/2022] Open
Abstract
In this retrospective study, we compared the efficacy and safety of mechanical adjuvants in mucosal-sparing, mechanical endoscopic dacryocystorhinostomy (MMED) for primary acquired nasolacrimal duct obstruction (PANDO). 116 adult patients (90 female) aged 61 ± 11 received one of the following after MMED without topical mitomycin: no stenting or packing (group 1, n = 25), 1-week ostium packing by ribbon gauze (group 2, n = 29) or non-medicated absorbable gelatin sponge (group 3, n = 25), 8-week bicanalicular stenting (group 4, n = 28). 104 patients(92%) provided 12-month outcomes. Number of patients, age, gender, surgeon, and osteotomy size were comparable among groups (p = 0.4-0.9). Marginal significance was found in anatomical (group 1:80%, group 2:96.6%, group 3:96%, group 4:96.4%, p = 0.05) but not functional success (group 1:85%, group 2:85.7%, group 3:83.3%, group 4:88.9%, p = 0.75) at postoperative 12-month. Patients receiving any packing or stenting achieved better anatomical (96% versus 80%, p = 0.015) but not functional success (85% versus 86%, p = 0.90) compared to those receiving none. More patients receiving stenting developed postoperative granuloma than those who did not (87% versus 63%, p = 0.04). 1-week ostium packing was found to be as effective as 8-week bicanalicular intubation in improving anatomical outcome after MMED for PANDO. Functional outcome, however, did not differ among patients receiving mechanical adjuvant or not.

Graefes Arch Clin Exp Ophthalmol 2019; 257:1535-1540. [PMID: 31037489 DOI: 10.1007/s00417-019-04303-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2018] [Revised: 02/11/2019] [Accepted: 03/20/2019] [Indexed: 11/27/2022] Open
Abstract
PURPOSE To evaluate the clinical usefulness of the dacryoscintigraphy in patients with nasolacrimal duct obstruction prior to endoscopic dacryocystorhinostomy. METHODS One hundred thirty-five lacrimal views of endoscopic dacryocystorhinostomy (DCR) with a single surgeon for primary nasolacrimal duct obstruction (PANDO) were included. These were assigned into three groups according to the type of dacryoscintigraphy. Group 1 was a pre-sac obstruction pattern. Group 2 was an intra-sac obstruction pattern. Group 3 was post-sac obstruction pattern. Each group was evaluated for an anatomical and functional surgical success, presence of complications including granuloma, synechiae, and tube-induced inflammation at least 12 months after the surgery. RESULTS Both anatomical and functional success rate showed no significant difference among the three groups (P = .297 and .472 linear by linear association). Functional failure rate (functional failure/total failure) also showed no clinically significant differences between groups. Logistic regression analysis was performed to determine the factors associated with functional success. There were no statistically significant factors in age, sex, scintigraphy type, pre-operative endoscopic grade, post-operative granuloma, and synechiae. CONCLUSION In patients with nasolacrimal duct obstruction, preoperative evaluation of obstruction level using dacryoscintigraphy may be not useful for predicting the functional success of the endoscopic dacryocystorhinostomy.

Graefes Arch Clin Exp Ophthalmol 2018; 256:1993-2000. [PMID: 29858678 DOI: 10.1007/s00417-018-4024-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Revised: 05/05/2018] [Accepted: 05/23/2018] [Indexed: 11/28/2022] Open
Abstract
PURPOSE To determine the effect of granuloma formation in the ostium and intralesional steroid injections (ISIs) on the surgical outcome after endoscopic dacryocystorhinostomy (DCR) in patients with primary acquired nasolacrimal duct obstruction (PANDO). METHODS One hundred and eighty-three cases involving 142 patients were enrolled. The ostium granulomas were classified according to their location relative to the internal common opening (superior, anterior, and posterior positions) and to the vicinity of the ostium (inner, edge, and extra types). If an ostium granuloma was observed during the follow-up and its size increased, ISIs were performed using 0.3 ml of 40 mg/ml triamcinolone acetonide. The surgical outcomes were compared between cases with and without ostium granulomas and also between each granuloma position and type. RESULTS Ostium granulomas occurred in 71 (38.8%) of the 183 cases, and an ISI was applied in 65 cases with a mean of 2.1 injections. All of the granulomas regressed successfully after ISIs, with the success rate not differing between the cases with (85.9%) and without (83.9%) granuloma. There was no association between granuloma location and surgical outcome. However, the functional outcome was worse (60%) for inner granulomas (which are located within the ostial base) than for extra (87.8%) and edge (98%) granulomas. CONCLUSIONS ISIs can be easily applied by a surgeon to help regress an ostium granuloma and improve the ostial patency after DCR. Inner ostium granulomas are associated with a worse functional outcome, and the initiation of an early corrective intervention such as an ISI should be considered.
