Summary
Diode laser-assisted transcanalicular dacryocystorhinostomy (TCL-DCR) is a minimally invasive procedure for nasolacrimal duct obstruction. This study found an 83.3% success rate, demonstrating its effectiveness in restoring tear drainage.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Nasolacrimal duct obstruction (NLDO) causes epiphora and impacts quality of life.
- Traditional dacryocystorhinostomy (DCR) techniques can be invasive.
Purpose of the Study:
- To evaluate the efficacy of diode laser-assisted transcanalicular dacryocystorhinostomy (TCL-DCR) for NLDO.
- To analyze success rates, procedure time, and laser energy requirements.
Main Methods:
- A prospective case series of 126 consecutive TCL-DCR procedures in 122 patients.
- Utilized a 980 nm diode laser for osteotomy creation under endoscopic guidance.
- Bicanalicular silicone stent intubation was performed in all cases.
Main Results:
- The average procedure time was 12 minutes, with an average of 245 Joules of laser energy used.
- An overall success rate of 83.3% was achieved, defined by absence of epiphora and patent nasolacrimal drainage.
- The average follow-up period was 12 months.
Conclusions:
- 980 nm diode laser-assisted TCL-DCR with bicanalicular intubation is a safe and effective minimally invasive surgical option.
- The procedure offers a high success rate for treating nasolacrimal duct obstruction.
- This technique represents a valuable addition to lacrimal surgery.
