Abstract
Objective To investigate the diagnosis and surgery of orbital neurilemomas. Methods The data of 32 eyes of 32 patients with pathologically confirmed obital neurilemoma were analyzed retrospectively. Results Of 32 cases with orbital neurilememas , 18 patients were male(56.25%), 14 patients were female(43.75%). A/B ultrasound were applied in 32 cases, and neurilemomas was found low to medium reflect or echo in the ultrasound. CT scanning illustrated soft tissue with high density mass in 26 cases, 6 cases were heterogeneity. MR imaging were examed in 10 cases and most of the neurilememas located in the muscle cone or in the superior part of the orbit. Surgical approach was lateral orbitotomy in 18 cases(56.25%), anterior orbitotomy in 12 cases(37.50%), transcranial orbitotomy in 2 cases(6.25%). Visual acuity was improved in 8 eyes(25.00%), remained unchanged(46.87%), and decreased in 9 eyes(28.13%). Early postoperation ptosis in 7 eyes (21.87%), disturbance of eyeballs in 9 eyes(28.13%), and 2 eyes(6.25%) occurred recurrence. Conclusion Modern medical imaging, especially CT scanning and MRI, can demonstrate the site, configuration, and characteristics of the tumors, and contribute to the diagnosis and surgical approach.Complete orbital neurilemomas extirpation can decrease the rate of recurrence and complication.
