Non-endoscopic Mechanical Endonasal Dacryocystorhinostomy.

Area of Science:

• Ophthalmology
• Otorhinolaryngology
• Surgical Innovation

Background:

• Endoscopic dacryocystorhinostomy presents challenges including limited rhinostomy size, higher failure rates, and costly equipment.
• There is a need for alternative, cost-effective dacryocystorhinostomy techniques.

Purpose of the Study:

• To introduce and describe a modified non-endoscopic mechanical endonasal dacryocystorhinostomy (NE-MEDCR) technique.
• To present a feasible and less expensive alternative to endoscopic dacryocystorhinostomy.

Main Methods:

• The NE-MEDCR procedure is performed under general anesthesia with nasal mucosa decongestion.
• A vitrectomy light probe is inserted through the canaliculus for transillumination.
• Surgical steps involve nasal mucosa incision and removal, bone removal with a lacrimal punch, lacrimal sac incision, and silicone intubation.

Main Results:

• The NE-MEDCR technique avoids the need for expensive instrumentation.
• The procedure is adaptable to standard ophthalmic surgical settings.
• This method addresses limitations associated with endoscopic approaches.

Conclusions:

• The modified non-endoscopic mechanical endonasal dacryocystorhinostomy (NE-MEDCR) is a viable alternative to endoscopic techniques.
• NE-MEDCR offers a cost-effective and practical solution for dacryocystorhinostomy, improving accessibility.
• This technique is suitable for routine ophthalmic surgical environments.
