Summary
Endoscopic endonasal dacryocystorhinostomy (DCR) is increasingly replacing external DCR for lacrimal sac obstructions. However, current results suggest external DCR may still have a slightly higher success rate.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
- Surgical Techniques
Background:
- External dacryocystorhinostomy (DCR) was the gold standard for lacrimal sac or nasolacrimal duct obstructions.
- Endoscopic endonasal techniques have gained prominence, particularly with advancements in functional endoscopic sinus surgery (FESS).
Purpose of the Study:
- To review reasons for lacrimal sac obstruction and diagnostic procedures.
- To compare external DCR with endoscopic endonasal DCR techniques.
- To discuss the role of adjuvants in DCR surgery.
Main Methods:
- Literature review comparing external and endonasal dacryocystorhinostomy.
- Analysis of diagnostic procedures and therapeutic indications.
- Discussion of surgical modifications and adjuvant use (laser, mitomycin, fluorouracil, silicon intubation).
Main Results:
- Endoscopic endonasal DCR is increasingly performed by ENT surgeons and ophthalmologists.
- Published success rates for endonasal DCR appear slightly lower than those for external DCR.
- Adjuvants and modifications to endonasal techniques are discussed.
Conclusions:
- While endonasal DCR is gaining acceptance, external DCR may offer superior success rates.
- Further research may be needed to optimize endonasal DCR outcomes.
- The choice of technique depends on patient factors and surgical expertise.

Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Tracheostomy Decannulation
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
