Purpose: Advances in surgical approaches have improved access for total or near-total resection of spheno-orbital meningiomas (SOM). Herein, the outcomes of multidisciplinary resection and reconstruction of SOM via frontotemporal orbitozygomatic craniotomy at a single institution are evaluated. Methods: A retrospective chart review was performed of all patients with SOM who underwent joint neurosurgical and oculofacial plastic resection via frontotemporal orbitozygomatic craniotomy between January 1999 and December 2018. Demographic data, clinical presentation, risk factors for meningioma, radiographic imaging, pathology results, postoperative outcomes, and surgical complications were reviewed. The outcome measures assessed included visual acuity, pupillary function, color vision, ocular motility, visual fields, and proptosis. Results: A total of 48 patients were identified having had multidisciplinary frontotemporal orbitozygomatic craniotomy for SOM of which 43 met inclusion criteria. A mean follow-up period of 23.9 ± 20.4 months (range 1-60) was observed. There were 35 patients who underwent primary resection and 8 patients who had prior surgical resection. The main presenting complaints were proptosis (88%), headache (44%), and reduced vision (12%). Gross total resection was achieved in 15 patients (35%) while near-total or subtotal resection was achieved in the remainder. Histologic analysis revealed World Health Organization grade I meningioma in 72% of tumors, grade II in 23%, and grade III in 5%. Mean visual acuity (Logarithm of the Minimum Angle of Resolution) improved from 0.24 ± 0.46 preoperatively to 0.09 ± 0.13 postoperatively (p = 0.03). Surgery improved proptosis, with a reduction in mean Hertel exophthalmometry from 22.37 ± 3.78 mm to 17.91 ± 3.84 mm (p < 0.001), of which 80% had no residual proptosis or developed subsequent recurrence. Exophthalmic index calculated by radiologic evaluation also improved from a mean preoperative value of 1.32 ± 0.19 to 1.12 ± 0.13 at the 6-month interval after surgery (p < 0.001). Before surgery, 19 (45%) patients had a relative afferent pupillary reaction with improvement in 9 (24%) after surgery. Of the 14 (33%) patients with preoperative ocular motility deficit, 7 (16%) had resolution of ocular motility deficit postoperatively. The most common surgical complications were temporalis muscle atrophy with temporal hollowing (14%), wound infection (7%), neurogenic strabismus secondary to trochlear nerve palsy (5%), restrictive strabismus (5%), and aponeurotic blepharoptosis (5%). Conclusions: Multidisciplinary frontotemporal orbitozygomatic for resection of SOM is a safe and effective means of tumor removal. It can provide improved visual acuity and proptosis metrics, as well as relief of optic neuropathy and ocular motility deficits.
