Summary
This study compared endonasal endoscopic dacryocystorhinostomy (DCR) with and without nasolacrimal stents. Both methods showed success, with stenting achieving a slightly higher success rate of 96% versus 92% without stents.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Nasolacrimal duct obstruction causes epiphora.
- Endonasal endoscopic dacryocystorhinostomy (DCR) is a minimally invasive surgical approach.
Purpose of the Study:
- To compare the outcomes of endonasal endoscopic DCR with and without nasolacrimal stents.
- To evaluate the efficacy and success rates of both surgical techniques.
Main Methods:
- A prospective randomized comparative study of 50 patients undergoing endonasal endoscopic DCR.
- Patients were divided into two groups: 25 with silicone stents and 25 without.
- Follow-up assessments were conducted postoperatively at regular intervals.
Main Results:
- Both groups showed improvement in nasolacrimal duct obstruction and epiphora.
- Success rates were 96% for endonasal DCR with stents and 92% without stents.
- The majority of patients were females aged 40-49, with a higher incidence on the left side.
Conclusions:
- Endoscopic DCR is a safe and effective procedure for nasolacrimal duct obstruction.
- Short-term silicone intubation (6 weeks) in endonasal DCR is safe and successful.
- Close postoperative follow-up is crucial to manage complications and improve success rates.

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

430
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
