Greater superficial petrosal nerve (GSPN) schwannomas are very rare tumors. There are only 15 reports, described so far. In this study the authors discuss the clinical presentation, radiological features, surgical approach, post-operative outcome and follow up of 3 cases of this rare schwannoma of the middle fossa, possibly originating from GSPN together with the review of existing literature. The presenting features were facial paresis in all cases, xerophthalmia in case 1, and tinnitus in case 2. Imaging studies showed a sub-temporal extradural mass on the anterosuperior aspect of the petrous bone in all cases. All tumors were removed through a subtemporal extradural microsurgical approach. Improvement of facial weakness and xerophthalmia as an end result is characteristic post-operative finding. © Ansari et al.; Licensee Bentham Open.
