[Choice of anesthetic method and prevention of ophthalmic complication in sphenoid sinus endoscopic surgery].

OBJECTIVE

To evaluate the anesthetic method and the prevention of the ophthalmic complication in endoscopic surgery for sphenoid sinus disease.

METHOD

All 65 patients underwent local anesthesia with improved surface anesthesia. Arrest blood completely in the surgical operation. The position of sphenoid sinus, the assimilation and destruction of sinus wall, the location and the appearance of lesion were determined carefully. To avoid damaging the optic nerve, the behavior of eyes was observed intently.

RESULT

The follow up period ranged from 6 months to 2 years. Five patients were lost to follow up. 53 of 60 patients recovered. 7 patients had recurrence among them with 2 cases of inverted papilloma and 5 cases of spheniod sinusitis with nose polyp, but they were successfully resected by endoscopic endonasal sinus surgery. Ophthalmic complication occurred in 5 patients.

CONCLUSION

Endoscopic sphenoid sinus surgery can be performed successfully under local anesthesia with improved surface anesthesia. Familiarity with the anatomic marker and variable anatomy, and meticulous surgical technique are essential for reducing ophthalmic complication.
