Abstract

Objectives Cranioorbital lesions present a great challenge for neurosurgeons and ophthalmologists. There is no consensus on the choice of surgical approach. The aims of this study were to investigate 49 cases of cranioorbital lesions and evaluate surgical approaches and outcomes. Patients and Methods A retrospective study was done on 49 patients (51 operations) from 2009 to 2018. Information about the lesion was used to decide whether the supraorbital eyebrow approach (SEA) or pterional approach (PA) was performed. Results Twenty-eight patients had surgical resection using SEA, 21 patients received PA, each group included one case of recurrence, who underwent reoperation via the same approach. SEA provided better cosmetic satisfaction, and a shorter incision than PA ( p < 0.05). There was no significant difference in total resection rates, visual outcomes, recovery of ptosis, and other new surgical-related complications between SEA group and PA group ( p > 0.05). Forty-nine cases of proptosis (94.1%, 49/51) were improved. Thirty-three patients (33/37, 89.2%) who underwent follow-up for longer than 12 weeks had a modified Rankin Scale (mRS) score ≤ 3. Conclusion Surgery is the preferred treatment for cranioorbital lesions, but total resection is difficult. SEA may be a more minimally invasive option for some more limited lesions superior to optic nerve. PA may be more reasonable for the lesion with obvious hyperostosis and more extensive lesions.
