Facial nerve schwanoma
Among parotid tumors, Eneroth could demonstrate two cases with neurogenic origin 4 and in a review of parotidectomies Nussabaum found only one case of neurilemmoma of the facial nerve 5. Multisession CyberKnife radio surgery allows us to treat schwannomas with multiple shots of a dose, which does not cause adverse effects. A study of four diverse cases. Favorable recovery was only observed in 16 patients who underwent stripping surgery. Schwannoma is a benign, capsulated perineural tumour of neuroectodermal derivation that originates from the Schwann cells of the neural sheath of motor and sensory peripheral nerves: I would be happy to review his specific neuro-imaging studies and clinical records to determine that with more certainty.
Extracranial Facial Nerve Schwannoma Treated by Hypo-fractionated CyberKnife Radiosurgery
My husband was recently diagnosed with a facial nerve schwannoma
Magnetic resonance imaging of facial nerve schwannomas. The facial nerve schwannomas are manifested in different ways. Perineural extension of a head and neck malignancy may follow the course of the greater superficial petrosal nerve and gain access to the temporal bone through the facial hiatus. Facial twitching followed by progressive paresis is also a common symptom of this type of tumor. Langerhans cell histiocytosis commonly affects the temporal bone; not only is it rare for this disease to produce a facial palsy but also more aggressive or destructive bone changes would be expected in Langerhans cell histiocytosis. Unlike schwannoma, malignant preservation difficult.
Facial Nerve Schwannoma of Parotid Gland: Difficulties in Diagnosis and Management
Introduction Facial nerve schwannomas are rare benign tumors, which originate along the facial nerve. Schwannomas and Neuro-fibromas are nerve damaging masses. This is because surgical tumor resection inevitably causes facial nerve palsy and requires a scheduled neuroanastomosis. Abstract Objectives Facial nerve schwannomas may be misdiagnosed as vestibular schwannomas VSs if the tumor is confined to the internal auditory canal IAC without involvement the geniculated ganglion or labyrinthine segment of facial nerve. A year-old female noticed a swelling in her right mastoid process. You are quite correct in that vestibular and trigeminal schwannomas are more common schwannomas. View at Google Scholar J.

To receive news and publication updates for Case Reports in Otolaryngology, enter your email address in the box below. We planned a fractionated CyberKnife radiosurgery for three consecutive days. Although it has been widely used for treating acoustic neuroma, there are few reports regarding its use in facial nerve tumors, however, the number is increasing 2. In the absence of pathological conditions, the geniculate ganglion is not usually observed under intravenous gadolinium-based enhancement.
