A new Y-shaped nasal mucosal flap with tumescent sponge support improves recovery after endoscopic dacryocystorhinostomy. This modified technique shows better endoscopic scores and fewer patient visits compared to the conventional D-shaped flap.
Area of Science:
- Otolaryngology
- Ophthalmology
- Surgical Innovation
Background:
- Endoscopic dacryocystorhinostomy (DCR) is a surgical procedure to restore tear drainage.
- Conventional DCR techniques can have variable postoperative recovery outcomes.
- Optimizing flap design and support is crucial for successful DCR outcomes.
Purpose of the Study:
- To introduce and describe a novel modified Y-shaped nasal mucosal flap with tumescent sponge support for endoscopic DCR.
- To compare the postoperative recovery between the modified Y-shaped flap and the traditional D-shaped flap in endoscopic DCR.
Main Methods:
- A retrospective comparative study involving 25 patients (Group A) with the modified Y-shaped flap and 30 patients (Group B) with the conventional D-shaped flap.
- Postoperative follow-up at 1 week, 1 month, 3 months, and 12 months.
- Assessment of endoscopic scores and number of otorhinolaryngology and ophthalmology visits.
Main Results:
- Group A demonstrated significantly lower Lund-Kennedy endoscopic scores at 1 week, 1 month, and 3 months postoperatively compared to Group B.
- Patients in Group A required fewer postoperative visits to otorhinolaryngology and ophthalmology departments.
- At 12 months, Group A achieved a 100% anatomical patency rate and a 96% symptomatic cure rate, versus 90.0% and 83.3% for Group B, respectively.
Conclusions:
- The modified Y-shaped nasal mucosal flap with tumescent sponge support offers excellent anatomical patency and symptomatic cure rates in endoscopic DCR.
- This innovative technique leads to improved postoperative recovery, evidenced by lower endoscopic scores and reduced patient visits.
- The modified Y-shaped flap represents a promising advancement in endoscopic dacryocystorhinostomy surgical procedures.
