Vestibular evoked myogenic and periocular potentials after vestibular schwannoma surgery
No full textObjectives: We analyzed the behavior of preoperative and postoperative vestibular evoked myogenic potentials (VEMPs) and vestibular evoked periocular potentials (VEPPs) in 3 patients who had vestibular schwannoma and underwent modified translabyrinthine surgery. Methods: We compared VEMPs and VEPPs, measured with both air-conducted (AC) and bone-conducted (BC) stimulations. Vestibular evoked potentials were measured both in the immediate postoperative period and some months later. Results: At the immediate postoperative examination, VEPPs were preserved in all 3 patients with both AC and BC stimulations. The VEMPs showed stable or improved parameters in 2 of our patients and were absent in the third patient. At the follow-up examination, VEMPs did not show any significant change with respect to the previous evaluation: In contrast, VEPPs were absent in 2 of our patients with AC stimulation and in I patient with BC stimulation. Conclusions: Our results seem to indicate a greater stability and reproducibility of VEMPs compared with VEPPs. In 1 patient, who had a schwannoma of the inferior vestibular nerve, the preservation of VEPPs and the absence of VEMPs in the immediate postoperative period confirm that the saccule represents the origin of VEMPs. Furthermore, these results suggest that not only the saccule, but also the utriculus, could be implicated in the origin of VEPPs

Unilateral vestibular schwannoma associated with a Jacobson's schwannoma
No full textCoexistence of unilateral vestibular schwannoma and Jacobson's schwannoma growing in the same intracranial site is rarely observed. We present the case of 36-year-old woman with primary diagnosis of vestibular schwannoma and subsequent appearance of schwannoma to the Jacobson's nerve. Initial wait and see strategy was performed offered us the opportunity to describe Jacobson's lesion features at computed tomography over a period of 4 years. Subtotal petrosectomy with infralabyrinthine approach was subsequently executed to remove the growing mass of the temporal bone. The Jacobson's schwannoma increased its size from 0.4 cm for years whereas vestibular schwannoma size was unchanged after 7 years observation. The concomitant removal of both schwannomas is still associated with the size of the CPA lesion and to patient's symptoms
Solitary nonfamilial desmoplastic trichoepithelioma of the external auditory canal
No full textSolitary desmoplastic trichoepithelioma is a benign adnexal neoplasm first described by Brownstein and Shapiro in 1976. It can be solitary or multiple, familial or not familial.
We present the case of a young man affected by solitary non familial desmoplastic trichoepithelioma of the external auditor canal (EAC). Clinical and histological findings are described. To our knowledge this is the first reported case of solitary desmoplastic trichoepithelioma of the EAC
