Abstract:

Symptomatic epiphora due to nasolacrimal duct obstruction (NLDO) is a common disorder and external dacryocystorhinostomy (DCR) is still considered the gold standard for its treatment. But with minimally invasive scar less surgery becoming the demand of the modern day ophthalmic surgery, there has been a renewed interest in the development of endoscopic technology. The transnasal approach to DCR was initially described a century ago. A rekindling of interest in this route led to the use of lasers in DCR.

Chronic dacryocystitis is   the indication for   Endoscopic Dacryocystorhinostomy. The surgical procedure of diversion of lacrimal flow within nasal cavity through an artificial fistula made at the level of lacrimal sac is called dacryocystorhinostomy. Initially external DCR gained popularity largely due to simplicity of technique and complexity of endonasal approaches. Recently after the advent of endoscopes, endonasal DCR regained popularity. This is largely due to technical advances in the rhinological instrumentations and endoscopes. In the study we comprehensively anal

RESULTS Overall, 531 questionnaires were returned, giving a response rate of 66.7%. Of these, 108 (20.6%) respondents indicated they were involved in lacrimal surgery. The majority of otolaryngologists seem to work in collaboration with ophthalmologists. In our survey, 98% (106) perform endoscopic dacryocystorhinostom

ABSTRACT Background: Endoscopic Endonasal Dacryocystorhinostomy (DCR) is common surgical procedure in the treatment of chronic dacryocystitis to overcome the distal naso-lacrimal system obstruction; nonetheless, after surgery, stenosis, and failure are common. Despite the satisfactory results obtained with the traditional external approach, the disadvantage of this method is the need for skin incision that cause consequent scar. Objective: To assess the outcomes of Endonasal Endoscopy Dacryocystorhinostomy with preservation of nasal and lacrimal mucosa Patients and methods: This was a clinical

Abstract:

Background: Chronic dacryocystitis is a common condition caused by an obstruction in the nasolacrimal duct, leading to excessive tearing, recurrent infections, and discomfort. The condition is often managed through dacryocystorhinostomy (DCR), which can be performed via two primary techniques: external DCR and endoscopic endonasal DCR. The external approach, a well-established procedure, requires an incision over the lacrimal sac, while the endoscopic technique offers a minimally invasive alternative with no external incision. The effectiveness, complication rates, and recovery times of these

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">The introduction of endoscopes with different degrees of angulation for endoscopic sinus surgery led to widespread use of endoscopic endonasal DCR (EDCR). The results of EDCR are not only encouraging, but are associated with many other additional advantages. Many modifications like LASER assisted endoscopic DCR, use of silicon tube for stenting, mitomycin-C application etc. have been described. However, insertion of silicon stent in endonasal DCR is most commonly used procedure. Many surgeons claim that

Abstract:

Abstract Endoscopic dacryocystorhinostomy is an established surgery for nasolacrimal duct block. We did a prospective study to evaluate the results and advantages. All the 90 patients underwent endoscopic DCR and 26 patients had septoplasty simultaneously. Postoperative evaluation of patency and relief of symptoms was done up to 6th month. Our study concludes that endoscopic. DCR is a safe, simple procedure with a better success rate and fewer complications along with review of literature.

Abstract:

BACKGROUND Dacryocystorhinostomy (DCR) can be performed via two approaches either external approach or endonasally. Earlier, external approach was preferred but with the recent introduction of endoscopy, the focus has shifted to endoscopic DCR as it is a less invasive procedure. This study was conducted to compare both the approaches. METHODS 50 patients were selected from patients attending eye and ENT OPD of a medical college in Kolkata with complaints of watering and / or discharge or with other features of chronic dacryocystitis e.g., mucocele, pyocele etc. They were then allocated in to t

<p class="abstract"><strong>Background:</strong> Dacryocystorhinostomy (DCR) is a surgical procedure performed to relief nasolacrimal duct obstruction, which involves the creation of ostium at the lacrimal bone to form a shunt in the nasolacrimal pathway. Closure of the rhinostomy opening was considered a major factor for surgical failure. Use of silicone stent in endoscopic DCR to improve the success rate of the operation have been tried by many surgeons.

Abstract:

Dacryocystorhinostomy (DCR) is the ‘gold standard’ treatment for nasolacrimal duct obstruction (NLDO). However, despite its recent technical advancements, complications are possible. Herein, to the best of our knowledge, we present the first reported case of delayed unilateral pneumocephalus after bilateral endoscopic DCR. An 85-year-old man with bilateral NLDO underwent endoscopic DCR with silicone intubation. After 1 month, he became lethargic and was admitted to emergency room. Brain CT demonstrated left pneumocephalus and a suspected microfistula in left orbital wall. Intravenous antibioti
