[Semiconductor laser use in endoscopic transnasal dacryocystorhinostomy]

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Context:

• Nasolacrimal duct obstruction is a common condition requiring surgical intervention.
• Endoscopic transnasal dacryocystorhinostomy is a standard surgical approach.
• Minimally invasive techniques are increasingly preferred in sinonasal surgery.

Purpose:

• To evaluate the efficacy and benefits of using a semiconductor laser in endoscopic transnasal dacryocystorhinostomy.
• To assess the impact of semiconductor laser on surgical outcomes and patient recovery.

Summary:

• This study investigated the application of a semiconductor laser in 8 patients undergoing endoscopic transnasal dacryocystorhinostomy for nasolacrimal duct obstruction.
• Following septal resection, polypectomy, or sinus resection, a fiberoptic probe identified the lacrimal sac, and laser resection of overlying mucosa and bone was performed.
• Seven patients achieved complete epithelization and patent ostia at six months. One case of restenosis was successfully re-treated with the semiconductor laser, resulting in a patent ostium.

Impact:

• Semiconductor laser use significantly reduces intraoperative bleeding, adhesion formation, and granulation tissue.
• The technique offers a simpler, faster, and effective method for endoscopic dacryocystorhinostomy.
• This approach holds promise for improving surgical success rates and patient outcomes in treating nasolacrimal duct obstruction.
