RESUMO

Complex congenital lacrimal drainage anomalies are known to be associated with several syndromes and present unique surgical challenges. Duplication of human body structures is uncommon and has been reported in the uterus (uterine didelphys), ureter (duplex ureter), duodenum, transverse colon, and nose. Lacrimal drainage anomalies have been reported in proboscis lateralis. To the best of the authors' knowledge, there are no prior reports on duplication of the lacrimal sac. The present case reports a complex congenital nasolacrimal duct obstruction that was associated with duplication of the lacrimal sac and the presence of 3 canaliculi.

RESUMO

To compare the success rates of probing with or without monocanalicular intubation, and/or inferior turbinate fracture in resolving simple congenital nasolacrimal duct obstruction (CNLDO). A randomized, double-blind clinical trial was conducted on children aged 12-36 months exhibiting symptoms of epiphora and/or mucous discharge along with a positive fluorescein dye disappearance test (DDT). Patients were randomly assigned to one of the following interventions: (1) probing; (2) probing and monocanalicular intubation; (3) probing and inferior turbinate fracture; (4) probing, inferior turbinate fracture, and monocanalicular intubation. Participants were categorized into two age groups (12-24 months and 24-36 months) and assessed for resolution of CNLDO three months post-surgery. Success was defined as the absence of epiphora or mucopurulent discharge and a negative DDT. Among the 201 participants, 51 underwent probing alone, 53 underwent probing with intubation, 47 underwent probing with turbinate fracture, and 50 underwent probing with turbinate fracture and intubation. No significant differences were observed in age, gender, or laterality of the disease between the groups (Ps > 0.05). While there was no significant difference in success rates among interventions in both age groups (Ps > 0.05), patients aged 24-36 months who underwent interventions involving intubation exhibited a significantly higher success rate compared to those without intubation (93.0% vs. 76.2%; P = 0.018). However, this difference was not observed in patients aged 12-24 months (95.7% vs. 92.9%; P = 0.551). Incorporating interventions such as intubation and/or turbinate fracture alongside conventional probing does not significantly alter the success rate of simple CNLDO resolution in children aged 12-24 months. However, older patients (24-36 months) may derive greater benefits from interventions involving intubation.

RESUMO

PURPOSE: The most prevalent lacrimal apparatus dysfunctions associated with differentiated thyroid cancer(DTC) after I-131 therapy are dry eye and nasolacrimal duct obstruction(NLDO), leading to ocular discomfort and lower quality of life for patients. It is crucial to diagnose and manage lacrimal apparatus dysfunction associated with I-131 therapy for DTC. Therefore, this review aims to comprehensively summarize and analyze the advances in mechanisms and therapeutic options underlying lacrimal apparatus dysfunction induced by I-131 therapy for DTC. METHODS: A comprehensive search of CNKI, PubMed, and Wed of Science was performed from the database to December of 2023. Key search terms were "Thyroid cancer", "I-131", "Complications", "Dry eye", "Epiphora", "Tear", "Nasolacrimal duct" and "NLDO". RESULTS: The research indicates that I-131 therapy for DTC causes damage to the lacrimal glands and nasolacrimal duct system, resulting in symptoms such as dry eye, epiphora, and mucoid secretions. Moreover, recent research has focused on exploring relevant risk factors of the condition and experimental and clinical treatments. However, there is some controversy regarding the mechanisms involved, whether it is due to the passive flow of I-131 in tears, active uptake of I-131 by the sodium-iodide symporter (NIS) in the lacrimal sac and nasolacrimal duct, or secondary metabolic and hormonal disturbances caused by I-131. CONCLUSION: It is crucial for early detection and preventive measures by ophthalmologists and the need for further studies to elucidate the mechanisms underlying the disease.

RESUMO

BACKGROUND: This prospective clinical study evaluates the effect of a silicone stent tube (SST) on the success rate of endonasal-endoscopic dacryocystorhinostomy (EN-DCR) to treat primary acquired nasolacrimal duct obstruction. METHODS: Patients were randomly assigned to receive EN-DCR with or without SST intubation over a period of 3 months. The surgery was performed using standardized techniques. Patients were assessed at three different timepoints: one day, 12 weeks and 24 weeks after the surgery. The results were compared in order to evaluate statistical differences. Surgical success was determined by means of positive irrigation procedures, as well as by the improvement of symptoms and a high level of patient satisfaction. RESULTS: A total of 56 randomized cases completed 24 weeks of follow up. 1 Patient dropped out due to malignant genesis of the nasolacrimal duct obstruction. After 24 weeks of follow up no statistically significant differences in levels of epiphora (p > .10) or patency (p > .16) were revealed. Comparisons regarding changes in time did not show levels of significance (p > .28). CONCLUSIONS: This study could not confirm a statistically significant benefit or disadvantage for SST Insertion in EN-DCR.

RESUMO

PURPOSE: Exploring the prevalence of dry eye (DE) and the changes of tear film stability in patients with primary acquired obstruction of the nasolacrimal duct (PANDO). METHODS: In this cross-sectional, observational study, 370 eyes in 223 patients with PANDO were assessed. The ocular surface disease index (OSDI) was used to evaluate ocular surface symptoms, and the Keratograph 5M non-invasive ocular surface analyser was used to assess ocular surface parameters. According to the TFOS DEWS II criteria, patients with OSDI ≥ 13 and NIKBUT < 10 s were diagnosed with DE. RESULTS: Of the 223 PANDO patients, 65 (29.1%) met the diagnostic criteria for DE. Compared with patients without DE, PANDO patients with DE were significantly older (p < 0.001), had a longer duration of epiphora (p = 0.023), and more likely to have a positive regurgitation on pressure over the lacrimal sac (ROPLAS) sign (p = 0.003). Multifactorial analysis showed that older age, positive ROPLAS and hypertension were significant independent predictors of DE (p < 0.05). Among the 147 unilateral PANDO patients without DE, the TMH, NIKBUT-first, NIKBUT-average and bulbar erythema scores were significantly higher in the PANDO sides. CONCLUSIONS: This study illustrated the prevalence of DE in PANDO patients was 29.1% and DE is more likely to occur in those who are older, have hypertension and are positive for ROPLAS. In addition, in patients with unilateral nasolacrimal duct obstruction, a decrease in tear film stability was observed in the healthy eye.

RESUMO

OBJECTIVE: Congenital nasolacrimal duct obstruction (CNLDO) is a pediatric disorder with a wide range of pathology. If untreated, the condition may end up with serious complications. Multiple treatment options for CNLDO exist throughout the literature, and there is an ongoing debate on the best intervention for each disease subgroup and the best timing of such interventions. This study compares the success and failure rates of silicone tube intubation (STI) against probing and balloon dilation (BD). METHODS: The authors searched the literature for relevant articles using PubMed, Scopus, web of Science, and Cochrane Library until January 2024. Using RevMan 5.4, the authors compared STI's success and failure rates to probing and BD using risk ratios (RRs) and a random-effect model. In addition, the complication rate of monocanalicular intubation (MCI) versus bicanalicular intubation (BCI) was investigated. The authors used the leave-one-out method to check for influential studies and to resolve heterogeneity. RESULTS: The screening process resulted in 23 eligible articles for inclusion in the authors' review. Silicone tube intubation had a higher chance of resolving the symptoms of CNLDO than probing (RR = 1.11; 95% CI: 1.04, 1.20; P = 0.004) while having less risk of surgical failure (RR = 0.48; 95% CI: 0.30, 0.76; P = 0.002]. Monocanalicular intubation showed no statistically significant difference when compared with BCI in terms of surgical success and failure; however, MCI had a lower risk of complications (RR = 0.68; 95% CI: 0.48, 0.97; P = 0.04). In addition, STI did not demonstrate any significant difference from BD. CONCLUSION: There was no significant difference in success/failure between MCI and BCI; monocanalicular had fewer complications. Silicone tube intubation did better in terms of surgical success than probing, especially in children over 12 months, suggesting that it is the preferred intervention for older patients with CNLDO.

RESUMO

PURPOSE: To investigate whether patients with craniosynostosis exhibit higher rates of nasolacrimal duct obstruction (NLDO) and to explore potential risk factors. METHODS: Retrospective review including all craniosynostosis patients treated at both the Divisions of Ophthalmology and Plastic, Reconstructive, and Oral Surgery at The Children's Hospital of Philadelphia between 2009 and 2020 was conducted. Synostosis characteristics, lacrimal disorders, and genetic data were collected. Main outcome measures were the rate of NLDO and associations with anatomical and syndromic/genetic risk factors. RESULTS: The total of 767 participants had a mean age of 2.8 ± 3.8 years, 465 (60.6%) were males, 485 (63.2%) had no syndromic association; 631 (82.3%) had one major suture involved, 128 (17%) had involvement of 2 to 4 major sutures, and 429 (55.9%) underwent craniofacial surgery. Forty-eight (6.2%) patients had NLDO, which more prevalent in the genetic/syndromic group (11.0% vs. 3.5%, respectively, p < 0.001), with the highest prevalence observed in patients with Apert syndrome (n = 4, 30.8%). The genetic variants most associated with NLDO were EFNB1 (n = 1, 100%) and FGFR2 (n = 6, 19.4%). There was no association between NLDO and the number or types of sutures involved or a history of craniofacial surgery. CONCLUSIONS: Nasolacrimal duct obstruction is more common in patients with craniosynostosis compared to the general population. Having a putative syndrome or a putative genetic variant and female sex were risk factors for NLDO. Ophthalmic evaluations for all craniosynostosis patients and careful assessments of any symptoms of tearing are recommended.

RESUMO

PURPOSE: Data supporting treatment recommendations for congenital nasolacrimal duct obstruction (CNLDO) in patients with craniofacial abnormalities is scarce. This study reports the incidence, clinical features, and outcomes of patients with concomitant craniofacial abnormalities and CNLDO. METHODS: This multi-center, retrospective, population-based cohort study included all patients diagnosed with CNLDO before age 6 during a 10-year period in a single US county. RESULTS: Of the 17,713 live births during the study period, 1998 infants were diagnosed with CNLDO, among whom 41 (2.05%) had associated congenital craniofacial abnormalities, yielding a birth prevalence of 23.1 (95% CI 16.6-31.4) per 10,000 live births. Craniofacial patients were significantly older at time of diagnosis (6.2 months) compared to uncomplicated CNLDO (3.7 months; p = 0.035). There was no significant difference in mean age at spontaneous CNLDO resolution, but 31.7% of craniofacial patients required probing for CNLDO resolution, compared to 14.5% in the CNLDO group (OR 2.76 [95%CI 1.41-5.39] p = 0.003). All but two patients with craniofacial abnormalities had resolution of symptoms after initial probing. Intraoperative probing findings indicated that 8 of 13 craniofacial patients had complex obstructions. CONCLUSIONS: The similar age at spontaneous resolution indicates that watchful waiting until approximately one year of age is a reasonable approach even in patients with craniofacial abnormalities, though more of these patients may require surgical intervention.

RESUMO

BACKGROUND: Utilizing expanded endoscopic approaches to the maxillary sinus for the endonasal management of a variety of tumors is increasing in popularity. The nasolacrimal duct (NLD) may be injured inadvertantly or need to be removed during tumor resection or to augment visualization. Management of the NLD can take the form of transection alone, transection with stenting, or performing a formal dacryocystorhinostomy to avoid postoperative sequelae of injury. The purpose of this study was to review the literature and determine the optimal management of the NLD during expanded maxillary sinus approaches. METHODS: A systematic review of Ovid, Embase, Medline, and Cochrane databases was performed to identify studies involving expanded approaches to the maxillary sinus and that explicitly reported the status of the NLD and postoperative outcomes. RESULTS: Nineteen studies were included in the analysis and divided into two groups: NLD-preserving (n = 9 studies; n = 191 patients in aggregate) and NLD-involving (n = 10 studies; n = 296 patients in aggregate). In the NLD-preserving subgroup, one patient out of a subgroup aggregate of 191 patients (0.5%) developed epiphora. In the NLD-involving subgroup, sharp transection alone was the most common method of NLD removal and was associated with a low rate of epiphora (study rates: 0 to 18.2%; aggregated subgroup rate: 7.0%, 21 / 296). Spontaneous resolution of symptoms was common (60%-100% cases). CONCLUSIONS: The NLD should be preserved when feasible from an exposure and tumor-control perspective. When pathology or approach requires the removal of the NLD, rates of persistent epiphora are very low, regardless of surgical technique. When expanded maxillary approaches are employed, particularly for benign tumors, and require removal of the NLD, sharp transection is the simplest method of removal, provides a low rate of postoperative epiphora, and is supported by the available literature.

RESUMO

PURPOSE: The objective of this study was to analyze the impact of different factors on the success rate of probing for congenital nasolacrimal duct obstruction (CNLDO). METHODS: A retrospective analysis was conducted on 239 eyes of 202 patients who underwent probing for CNLDO between 2014 and 2019. Patients were divided into three age groups (12-24 months, 25-36 months, and over 36 months) and two groups based on the type of membranous obstruction (MO) and incomplete complex obstruction (ICO), with complete complex obstruction (CCO) cases being excluded. The study involved administering general anesthesia (GA) to all participants during the probing procedure. The patients were then monitored at scheduled intervals for up to 6 months after the surgery. Success was defined as an improvement in symptoms and signs, and logistic regression and Fisher's exact test were used for statistical analysis. RESULTS: The mean age of the patients was 25.48 ± 13.38 months, and the total success rate was 86.61%. The success rate for MO was 92.8%, 95.87%, and 97% in age groups 1, 2, and 3, respectively. The success rate for ICO was 91.17%, 80%, and 23.52% in age groups 1, 2, and 3, respectively. The success rate for MO was significantly higher than ICO in all age groups. The success rate for ICO was significantly lower in age group 3 (p = 0.009). CONCLUSION: The study found that probing performed within the first 36 months had high success rates regardless of age and type of obstruction. However, the success rate significantly decreased in patients undergoing probing for ICO at 36 months or later.

RESUMO

Among secondary forms of nasolacrimal duct obstruction caused by radioactive iodine therapy, its distal forms localized in the area of the Hasner's valve are predominant. In this regard, during dacryocystorhinostomy (DCR) there is a high probability of developing the sump syndrome, for which the anatomical prerequisite is that the lower edge of the DCR ostium is above the level of obstruction. In such cases, we propose to supplement DCR with a counteropening in the area of the Hasner's valve. PURPOSE: This study analyzes the clinical effectiveness of dacryocystorinostomy with a counteropening. MATERIAL AND METHODS: The outcomes of 49 surgeries (49 patients) with secondary acquired nasolacrimal duct obstruction due to radioactive iodine therapy were analyzed, including 34 DCR and 15 DCR with a counteropening. The clinical outcomes were analyzed over the longest possible period after surgery. The analysis included the severity of tearing on the Munk scale, the characteristic of the formed ostium on the M. Ali scale and the height of the tear meniscus. Differences were considered significant at a confidence level of 95% (p≤0.05). RESULTS: Analysis of the results of the performed surgeries showed that DCR was clinically effective in 30 (88%) cases, DCR with a counteropening - in 15 (100%) cases. The differences were not statistically significant in the total sample, but were statistically significant when comparing the results of surgeries in patients with distal obliteration. CONCLUSION: The developed and clinically tested method of DCR with a counteropening in the area of the Hasner's valve was completely effective in 15 patients with secondary nasolacrimal duct obstruction caused by radioiodine therapy.

RESUMO

The article analyzes the literature data concerning the anatomical structure of the tear ducts with a focus on morphometric studies of individual structures. It is noted that, despite the high information content of cadaveric studies, most of the information to date has been obtained with the use of intravital radiation visualization methods. It is shown that the lacrimal drainage system has age, gender, and racial characteristics. Most studies focus on features of the bone nasolacrimal canal, while there is a relative shortage of research devoted to soft-tissue nasolacrimal duct. The analysis showed that most of the studies are devoted to particular morphometric indicators, which makes it difficult to obtain a complete objective picture of the size of the tear duct. Information about its volume can be found only in a couple of studies. The numerical values of the obtained data vary, which can be explained by a different approach to the selection of research subjects, sample sizes, anatomical criteria and the calculation method of morphometric parameters. There are only a few studies on morphometric parameters of the nasolacrimal duct in healthy humans, which is extremely important for determining the pathogenesis of disorders of the patency of the lacrimal drainage system.

RESUMO

A 47-year-old Japanese woman presented with a 1-year history of right-sided epiphora. On initial consultation, the patient had a high right tear meniscus height. CT images revealed bilateral soft tissue opacification in the nasal cavity and maxillary, frontal, and ethmoid sinuses. The lesion in the right nasal cavity and maxillary sinus involved the right lacrimal sac and nasolacrimal duct. Blood test results showed elevated eosinophil count. Endoscopic sinus surgery and excisional biopsy of the nasolacrimal duct were performed. Histopathological examinations of the excised right nasolacrimal duct and nasal polyps from the nasal cavity and maxillary sinus showed high levels of eosinophilic inflammatory infiltrates. The definite diagnosis of eosinophilic chronic rhinosinusitis was made, based on clinical, radiological, and histopathological findings. At 1.5-year follow-up, tear meniscus height was normal, the lacrimal drainage system remained patent, and the rhinosinusitis did not recur.

RESUMO

PURPOSE: To study the outcomes of balloon dacryoplasty (BD) or (BDCP) in children with persistent congenital nasolacrimal duct obstruction (pCNLDO) by using new and reused balloon catheters. METHODS: Our retrospective analysis focused on managing pCNLDO by using the BD or BDCP technique. The study included children aged >1 year to <12 years who underwent single or multiple probings before. Our specific lacrimal workup included a detailed history and examination, as published earlier. We used conventional, straight, 2 mm × 13 mm/3 mm × 15 mm lacrimal balloons (FCI, Ophthacath). We have described a technique to use the same catheter for three BD procedures (1 new + 2 reuse). The outcomes were categorized as complete success, partial success, and failure. The minimum follow-up of each child was 6 months. RESULTS: We analyzed 64 children (89 eyes) with a mean age of 58 months (15-132 months). All children (100%) had epiphora with discharge and positive FDDT. All children underwent BD under general anesthesia - new balloons in 59 eyes and reused balloons in 30 eyes. The balloons were plasma sterilized akin to vitrectomy cutters and tubings of phaco machines. We noted three leaks from reused balloons (2 from the balloon tip and 1 from the plastic hub). At a mean follow-up of 14.5 months, complete success was noted in 77 eyes (86.5%) (52 new and 25 reuse), while 8 eyes had partial success (8.9%) (4 new and 4 reuse). Failure of BD was noted in four eyes (4.5%) (3 new and 1 reuse). None had significant complications with new or reused balloons. CONCLUSION: BD or BDCP is a quick, safe, easy, and effective procedure that resolves pCNLDO symptoms satisfactorily. Carefully reusing a conventional balloon catheter is possible with comparable efficacy and no additional complications in pCNLDO.

RESUMO

Continuous exposure to foreign substances initiates a sustained inflammatory reaction in the body, and subsequent chronic inflammation is recognized as one of the causes of lymphoma. Most lymphomas caused by foreign bodies are composed of 2 major phenotypes. Diffuse large B-cell lymphoma arising from metallic prosthesis, also called metallic implant-associated lymphoma and T-cell phenotype anaplastic large cell lymphoma, commonly associated with breast implants. Augmentation rhinoplasty is often performed to improve the esthetics of the nasal dorsum and various synthetic materials have been used as implants. The occurrence of lymphoma originating from a nasal implant is scarcely documented, and even more uncommon is its manifestation as epstein-barr virus (EBV)-negative extranodal marginal zone lymphoma. Here, the authors describe a rare case of B-cell lymphoma of the nose and nasolacrimal duct in a 49-year-old woman who underwent rhinoplasty with a silicone implant 20 years ago.

RESUMO

PURPOSE: To report the incidence, clinical characteristics, and outcomes of acute dacryocystitis among a large, population-based cohort of children born with congenital nasolacrimal duct obstruction (CNLDO) over a 10-year period. METHODS: This multicenter retrospective, population-based cohort study included all patients diagnosed with acute dacryocystitis in a cohort of patients diagnosed with CNLDO before age 5 years in Olmsted County, Minnesota, United States of America from January 1, 1995, through December 31, 2004. RESULTS: Of 1,998 patients with CNLDO, there were 70 cases (36 female [(51%)]) of acute dacryocystitis during the study, yielding an incidence rate of 243 per 100,000 children (95% CI, 170-316). Mean age at diagnosis was 9.0 months. Patients who developed dacryocystitis were significantly less likely to be born via C-section (OR = 0.29, P = 0.009). Less than half of patients with dacryocystitis were treated with oral/intravenous antibiotics (46%), but whose who were had a significantly higher odds of requiring probing (OR = 8.50, P = 0.004). Spontaneous CNLDO resolution was significantly less likely to occur in patients diagnosed with acute dacryocystitis compared with those without (OR = 2.46, P = 0.001). The median age of spontaneous resolution in the dacryocystitis group (6.0 months) was significantly older than the uncomplicated CNLDO group (P = 0.012). CONCLUSIONS: Pediatric acute dacryocystitis is an uncommon complication of CNLDO and is associated with both a lower likelihood of and older age at spontaneous resolution of CNLDO symptoms.
