Background and Objectives
With the recent development of endoscopic nasal surgery, endoscopic sphenopalatine artery ligation allows for secure control of posterior epistaxis with considerably low recurrence and complications. Surgical approaches to the sphenopalatine foramen to ligate the sphenopalatine artery are transantral, intranasal, and transseptal. However, the procedures have considerable limitations. Therefore, we have revised the transturbinal approach, which was described by Togawa for intranasal vidian neurectomy in 1977, to ligate the sphenopalatine artery in two patients of intractable posterior epistaxis, and describe our technique of the trans-inferior turbinate approach for endoscopic sphenopalatine artery ligation.
SURGICAL TECHNIQUE: A longitudinal incision is made along the lower border of the inferior turbinate, and the mucoperiosteal flaps are developed to the lateral nasal wall. The posterior two-thirds of the inferior turbinate bone is removed from the lateral nasal wall. The posterior lateral nasal artery on the upper flap is positively identified, and followed to the posterior end of the middle turbinate bone. The sphenopalatine foramen can be localized after removing the posterior end of the middle turbinate bone, and the sphenopalatine artery is ligated with hemoclips or divided with bipolar electrocautery.
Results
With the trans-inferior turbinate approach, it was possible to identify and ligate the sphenopalatine artery and its branches in the sphenopalatine foramen with no immediate or delayed complications.
Conclusion
The trans-inferior turbinate approach provides unobscured surgical access to the posterior nasal cavity, and enough working space for endoscopic manipulation. The posterior lateral nasal artery is a reliable surgical landmark leading to the sphenopalatine foramen. |
