Nonvestibular Schwannomas of the Brain: A 7-Year Experience

Giant recurrent dumbbell-shaped hypoglossal schwannoma in an elderly male: A case report

“…The most recent preferential surgical approach is a far lateral approach with a partial resection of the condyle to open the hypoglossal canal (3,16). In order not to destroy the condyle and induce craniocervical instability, in the present study, a far lateral suboccipital approach (no drilling of the hypoglossal canal) in combination with a transcervical approach was used to resect the intra-and extracranial region of the tumor in a one-stage procedure.…”

“…For the management of benign cranial base tumors, particularly in patients with giant recurrent tumors and an advanced age, an individual end-point of surgery should be considered, taking into account the life expectancy of the patient and the natural course of the disease (16). Additional studies on hypoglossal schwannomas are required, particularly cases in which the hypoglossal schwannoma was not totally resected, not only in order to develop more definitive and secure surgical treatments, but also to reduce the resultant unnecessary suffering of patients.…”

“…Although 39 cases of dumbbell-shaped, hypoglossal schwannoma have been described in the literature to date (3,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), only a small proportion of these cases (<30%) achieved a complete tumor resection (12), and no recurrent cases were reported. At present, the standard surgical technique used for the treatment of hypoglossal schwannomas is the far lateral approach with partial resection of the condyle, which exposes the hypoglossal canal (3,16). Complete tumor resection is difficult due to intradural and extradural growth through the enlarged hypoglossal canal.…”

Surgical Management of Jugular Foramen Schwannomas With Hearing and Facial Nerve Function Preservation: A Series of 23 Cases and Review of the Literature

“…E-mail: mario.sanna@gruppootologico.it DOI: 10.1097/01.mlg.0000246193.84319.e5 4% of all intracranial schwannomas. 1,2 During the past 30 years, there has been a dramatic rise in the number of reports, [1][2][3][4][5][6][7][8][9] although the majority of the articles still present case reports. This increase may be attributed to enhanced physician awareness and the improvements in imaging techniques.…”

Gamma Knife surgery for trigeminal schwannoma

“…Despite this distinction, trigeminal schwannomas remain relatively rare and constitute between 0.8 and 8% of all intracranial schwannomas and less than 0.5% of all intracranial tumors. 3,12,22,29,32,[38][39][40]47 Complete resection can be curative; however, even in the best of hands it is associated with a risk of significant neurological complications and death. 29,32,38,39,47 Even more disheartening is the fact that gross-total resection is not always feasible, and lesion recurrence afterwards is not uncommon.…”
