Patients were categorized by tumor histology (squamous, transitional, and mixed cell) and growth pattern (exophytic, endophytic, or mixed). RESULTS: Thirty patients (18 female; 60%) presented at a mean age of 46...

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...

Lacrimal canalicular lacerations can be caused by trauma to the ocular adnexa, such as a penetrating or blunt injury. Only a few cases involving the common canaliculus or lacrimal sac have been reported, and only a few reports have described the detailed course of treatment. Here, we report an acute case of common lacrimal canalicular laceration and a case of a previous common canalicular laceration. The acute case was treated with a bicanalicular stent directly inserted into the nasolacrimal duct. The case with a previous common canalicular laceration was treated with external dacryocystorhinostomy combined with monocanalicular stent insertion...

BACKGROUND: A common complication of bicanalicular intubation is dislocation of the silicone tube. METHODS: Eleven patients with prolapsed silicone tubes who had undergone bicanalicular nasal intubation were injected with a 2 per cent lidocaine solution to infiltrate the lacrimal duct mucosa. A memory wire probe was used to pull a 4-0 suture through the lacrimal passage retrogradely, allowing the suture to grab the silicone tube. Paraffin oil was applied to the contact part of the rope and the silicone tube, then the distal end of the silk thread was removed from the nostril until the tube was pulled into place...

To estimate the safety and effectiveness of endoscopic nasal dacryocystorhinostomy in the remedy of chronic dacryocystitis. The clinical data of 105 subjects with chronic dacryocystitis enrolled into our hospital were analyzed retrospectively. The subjects were distinguished into nasal endoscopic group (endoscopic dacryocystorhinostomy; i.e., 51 cases) according to their surgical methods and external-route group (external-route dacryocystorhinostomy; i.e., 54 cases). The therapeutic effect, lacrimal gland secretion function, tear film stability, degree of epiphora, lacrimal passage patency, complications, and recurrence rate were contrasted between the 2 groups...

PURPOSE: To examine the long-term success rate of pediatric endoscopic DCR surgery via telephone questionnaires, as determined by patients and their parents. METHODS: This is a retrospective cohort study of all patients who underwent DCR surgery at the Schneider Children's Medical Center of Israel between 2010 and 2020. We performed long-term follow-ups to assess the quality of life, surgical complications, and satisfaction with surgical outcomes. RESULTS: Our study includes seventy-nine patients with a total of 108 eyes...

Primary nasal tuberculosis (TB) is a rare disease even in areas with high TB burden, possibly attributed to the protective mechanism of sinonasal mucosa. Its symptoms are subtle and can be mistaken for other granulomatous inflammatory conditions. We would like to report a case of a 70-year-old Indian lady who underwent a successful left endoscopic dacryocystorhinostomy three years ago and presented with recurrent left epiphora. During nasal endoscopy, multiple ulcerative masses with crusting were detected over the left nasal vestibule, anterior nasal septum, left inferior, and middle turbinate...

OBJECTIVE: The aim of this study is to show whether journals pay attention to double-organ bias in studies on dacryocystorhinostomy (DCR) treatment. Most statistical tests are based on the assumption that each data entry is independent of the other. However, we wanted to understand whether the eye, which is a double organ in the human body, is a cause of bias and whether sufficient attention has been paid to it in published articles. DESIGN: A PubMed search was conducted between November 1997 and November 2021 in the field of ophthalmology and otolaryngology with the terms 'dacryocystorhinostomy' and the limitations of 'people' and 'randomly controlled studies'...

AIMS: To compare the outcomes of endoscopic dacryocystorhinostomy (En-DCR) in chronic dacryocystitis (CD) with or without previous bicanalicular silicone tube intubation (BSTI), and investigate whether previous BSTI influenced postoperative outcomes. METHODS: We conducted a retrospective review of medical records of CD patients (group A) who had previously undergone BSTI for nasolacrimal duct stenosis and an age- and sex-matched control group of CD patients (group B) without previous intubation receiving En-DCR from November 2017 to January 2022...

PURPOSE: To evaluate the association between meibomian gland dysfunction (MGD) and primary chronic dacryocystitis (PCD) and the effect of dacryocystorhinostomy (DCR) on tear film stability and MGD. METHODS: This prospective, interventional, non-randomized study involved 50 unilateral acquired PCD cases and 50 age-matched healthy controls. Patients with lid abnormalities, ocular trauma, previous ocular surgery, contact lens wearers, and chronic topical or systemic drug users were excluded from the study...

PATIENTS AND METHODS: Chronic dacryocystitis patients who attended the Department of Oculoplastics, Zhongshan Ophthalmic Center, Sun Yat-sen University from January 2022 to June 2022 and had En-DCR were included...

OBJECTIVES: This study aims to investigate the influence of systemic inflammation on adult patients with acquired nasolacrimal duct obstruction (ANLDO). METHODS: Peripheral venous blood analysis was performed on adult patients who underwent dacryocystorhinostomy for ANLDO between June 2020 and December 2022, during their remission period just before the surgery. Platelet, Neutrophil, Lymphocyte, Monocyte, White Blood Cell (WBC) count, Platelet/Lymphocyte ratio (PLR), Neutrophil/Lymphocyte ratio (NLR), Monocyte/Lymphocyte ratio (MLR), and systemic inflammatory index (SII) (calculated as platelet × (neutrophil/lymphocyte)) were compared with a volunteer control group...

BACKGROUND: The present study was performed to compare the effectiveness of propofol-remifentanil and propofol-hydralazine in inducing controlled hypotension in patients undergoing the dacryocystorhinostomy (DCR) surgery and reducing their bleeding volume during surgery. MATERIALS AND METHODS: The present double-blind, randomized clinical trial was performed on 70 patients who were candidates for DCR surgery and divided into two groups. In both the groups, general anesthesia protocol was performed...

PURPOSE: This study aimed to examine the differences in the biofilms and physical deposits on Crawford stents compared to large-diameter stents. METHODS: A prospective interventional study was performed on a series of patients undergoing external or endoscopic dacryocystorhinostomy (DCR) and endoluminal lacrimal duct recanalization (ELDR) with either Crawford or large-diameter stents. All the Crawford stents were retrieved at six weeks and the large-diameter ones at eight weeks following the surgical intervention...

Dacryocystorhinostomy (DCR) is an effective surgical procedure for addressing lacrimal drainage problems. However, it can be a painful operation that involves incisions both inside and outside the eye, often leading to a high incidence of postoperative nausea and vomiting. Preemptive analgesics can be employed to alleviate this unrelieved pain. Nonetheless, many of the drugs used can induce a wide range of adverse effects. Therefore, the aim of this systematic review and meta-analysis is to assess the current evidence regarding the efficacy of pregabalin in managing postoperative pain following DCR surgery...
