Application of high-frequency electrosurgical scalpel and methylene blue staining in endonasal dacryocystorhinostomy.

PURPOSE: To evaluate the application of a high-frequency electrosurgical scalpel and methylene blue staining in the endonasal dacryocystorhinostomy.

METHODS

This retrospective study included 37 patients (43 eyes) undergoing endonasal dacryocystorhinostomy in our hospital between 2011 and 2013 using methylene blue staining of the lacrimal sac and a high-frequency electrosurgical scalpel for cutting nasal mucosa, intraoperative stanch, and fixation of lacrimal sac and nasal mucosal flaps. Surgical efficacy, intraoperative challenges, and corresponding handling methods were evaluated and summarized.

RESULTS

Among 43 eyes, 42 were successfully cured (97.7%) and the symptoms in 1 eye were improved (2.3%). Total efficacy rate was 100%. All surgeries were successfully performed. No severe intraoperative complications were observed.

CONCLUSION

A high-frequency electrosurgical scalpel, combined with methylene blue staining of the lacrimal sac, is efficacious for nasal mucosal cutting, intraoperative stanch, and fixation of mucosal flap by cauterization, which significantly alleviates intraoperative complications and enhances surgical success rate. It deserves widespread application in clinical practice.
