Objective
To evaluate the efficacy of combining an endonasal endoscopic skull-base
approach and repair with a transcranial
orbitozygomatic approach for spheno-orbital meningiomas (SOMs).
Methods
Three patients with recurrent SOMs underwent combined orbitozygomatic and endonasal endoscopic surgery. In 2 patients both procedures were done in 1 operation and in 1 patient the endonasal surgery was done 2.5 months after the craniotomy. Extent of resection, complications, morbidity, and mortality were evaluated.
Results
Gross total resection was achieved in 1 patient and near total resection in the other 2 patients with tumor left in the cavernous sinus and parapharyngeal space. Two patients suffered cranial neuropathy from the transcranial surgery and the other developed a pseudomeningocele. There were no complications from the endonasal surgery. Patients having combined single setting cranionasal surgery were discharged on day 6 and 8, whereas the patient having only the endonasal component on a later date was discharged on day 2.
Conclusions
A combined cranionasal approach involving transcranial orbitozygomatic and endonasal endoscopic approaches is an effective 2-stage surgery for resecting SOMs invading into the sinuses and paranasal compartments. The ability to perform a multilayer closure involving a vascularized nasoseptal flap additionally decreases the risk of postoperative cerebrospinal fluid leak.
