Summary
Endoscopic surgery offers a highly successful treatment for epiphora (watery eyes), significantly improving outcomes compared to older methods. This minimally invasive approach provides lasting symptom relief with a high success rate in most patients.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- External dacryocystorhinostomy (OCR) was previously the standard treatment for epiphora.
- External OCR had significant patient morbidity and a low success rate.
- Limited success rates and high morbidity associated with external OCR necessitated alternative treatments.
Purpose of the Study:
- To evaluate the efficacy of endoscopic endonasal dacryocystorhinostomy (OCR) for treating epiphora.
- To assess the success rate and patient outcomes of the endoscopic surgical approach.
- To compare the benefits of endoscopic OCR with traditional external methods.
Main Methods:
- A series of 30 patients with epiphora underwent endoscopic endonasal dacryocystorhinostomy.
- The procedure utilized an endoscope and detailed knowledge of nasal lateral wall anatomy.
- Patient follow-up ranged from 6 to 18 months to assess symptom relief.
Main Results:
- Successful symptom relief was achieved in 28 out of 30 patients after a single procedure.
- The remaining two patients experienced symptom relief following a second procedure.
- The endoscopic approach demonstrated a high success rate in treating epiphora.
Conclusions:
- Endoscopic endonasal dacryocystorhinostomy is a highly effective treatment for epiphora.
- This minimally invasive technique offers significant advantages over external OCR.
- The procedure provides excellent outcomes and lasting symptom relief for epiphora patients.

01:21Tracheostomy 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...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
