Surgical management of lesions of the sphenoid lateral recess.
BACKGROUND
Pneumatization of the sphenoid sinus occasionally includes an extensive lateral recess creating an area beneath the temporal lobe that is relatively inaccessible to surgical intervention. Pathology in this anatomic location presents special surgical and therapeutic challenges. Recently, several authors have described the endoscopic transpterygopalatine fossa approach to this anatomic region. This approach is associated with minimal morbidity while providing direct endoscopic surgical access for managing a variety of disease processes in this region.


METHODS
This study presents eight cases requiring this approach or a modification of this approach. Six patients presented with temporal lobe meningoencephaloceles with cerebrospinal fluid rhinorrhea. Each case was managed successfully through this surgical approach.


RESULTS
One patient experienced transient postoperative palatal anesthesia due to injury to the greater palatine nerve and another complained of ipsilateral dry eye postoperatively. Two other patients had neoplasms (inverting papilloma and chondrosarcoma), which were successfully addressed through this technique. There were no postoperative complications in these patients.


CONCLUSIONS
We have previously described the relationships of neural and vascular structures in this anatomic region. This article will review these relationships as they pertain to this surgical approach and will discuss the indications, techniques, and surgical outcomes in this series of patients. This approach is a valuable addition to the endoscopic armamentarium of the experienced endoscopic surgeon.
