Posterior nasal septectomy in endoscopic orbital apex surgery.
OBJECTIVE
To review cases of endoscopic orbital apex surgery using posterior nasal septectomy and describe the technique and benefits.


METHODS
A retrospective chart review of all cases of endoscopic orbital apex surgery with the use of intraoperative posterior nasal septectomy over a 3-year period. Three cases are described, and the technique and limitations and advantages of this approach are detailed.


RESULTS
Endoscopic orbital apex surgery cases over a 3-year period were reviewed. Three of these cases involved the use of posterior nasal septectomy. All 3 cases involved large lesions at the orbital apex and periorbital skull base. Two of the lesions also involved the cavernous sinus and one extended in the optic canal. The alternative for all patients would have involved a transcranial approach. During the mean follow-up of 9 months, no complications were noted.


CONCLUSIONS
The use of posterior nasal septectomy in endoscopic surgery has been used for access of the skull base. This is the first description of this technique for access of orbital apical lesions. This technique improves visualization and surgical access to the orbital apex and periorbital skull base, sparing the patient larger craniofacial surgeries. No complications were noted in this preliminary patient cohort.
